Abstract: Faecal prevalence of gastrointestinal bacterial pathogens, including Campylobacter, Escherichia coli O157:H7, Salmonella, Shigella,Yersinia, as well as Arcobacter, were examined in 317 faecal specimens from 44 animal species in Belfast Zoological Gardens, during July-September 2006. Thermophilic campylobacters including Campylobacter jejuni,Campylobacter coli and Campylobacter lari, were the most frequently isolated pathogens, where members of this genus were isolated from 11 animal species (11 of 44; 25%). Yersinia spp. were isolated from seven animal species (seven of 44; 15.9%) and included, Yersinia enterocolitica (five of seven isolates; 71.4%) and one isolate each of Yersinia frederiksenii and Yersinia kristensenii. Only one isolate of Salmonella was obtained throughout the entire study, which was an isolate of Salmonella dublin (O 1,9,12: H g, p), originating from tiger faeces after enrichment. None of the animal species found in public contact areas of the zoo were positive for any gastrointestinal bacterial pathogens. Also, water from the lake in the centre of the grounds, was examined for the same bacterial pathogens and was found to contain C. jejuni. This study is the first report on the isolation of a number of important bacterial pathogens from a variety of novel host species, C. jejuni from the red kangaroo (Macropus rufus), C. lari from a maned wolf (Chrysocyon brachyurus), Y. kristensenii from a vicugna (Vicugna vicugna) and Y. enterocolitica from a maned wolf and red panda (Ailurus fulgens). In conclusion, this study demonstrated that the faeces of animals in public contact areas of the zoo were not positive for the bacterial gastrointestinal pathogens examined. This is reassuring for the public health of visitors, particularly children, who enjoy this educational and recreational resource.

Abstract: Polydactylism, a genetic defect characterized by partial or complete duplication of the digit, has been described in a wide range of vertebrates. Among ungulates, polydactyly appears to be relatively common in domestic camelids, with reports in dromedary camels (Camelus dromedarius), llama (Lama glama) and alpaca (Vicugna pacos). However, in wild South American camelids polydactyly has been reported only in a vicuna kept in a zoo (Vicugna vicugna), but not in wild populations. Here a finding of polydactyly in a free-ranging guanaco is described. We propose the hypothesis that this malformation has an atavistic-genetic origin.

Abstract: The most important problems of Artificial Insemination (AI) in Camelidae is its timing in relation to ovulation in the she-camel. The present article reviewed collection of semen, processing of semen, manipulation of the female and semen deposition technique in Camelidae species. Commonly, semen is collected by electroejaculation, artificial vagina (AV), flushing of the epididymus with saline solution, while the more accepted methods are the former two methods. Semen is usually used in raw condition or after extension, depending on the method of semen processing. In the fresh raw method, whole semen is used within minutes or after few hours. Extension of the semen ejaculate is carried out by adding extenders and it is required in more efficient use of AI, in short-term preservation or liquid semen (within a few hours or days) and long-term preservation or frozen semen (months or years). In short-term preservation, semen is used extended under different temperatures (30, 25 or 4 degrees C). Long-term preservation is carried out by cryopreservation. Packaging methods such as pellets, ampoules or in plastic straws with different volumes (0.25, 0.5 or 4 ml) represent different freezing procedures. The quality and survival of spermatozoa of post-thaw semen are highly variable from one male to the other, even after using the same freezing technique. To ensure that the inseminated females ovulate, hormonal manipulation of ovarian activity is used such as the induction of follicular activity and ovulation, as well as, synchronization of these phases in a group of females. The best time for insemination can only be determined by ultrasonography and/or rectal palpation of the ovaries. The other alternative is to inseminate at known intervals following induction of ovulation by hormonal treatment with human-chorionic gonadotropin (hCG) or gonadotropin-releasing hormone (Gn-RH).

Abstract: Four camelid species exist in South America: two wild, the guanaco (Lama guanicoe) and the vicuna (Vicugna vicugna), and two domestic, the alpaca (Lama pacos) and the llama (Lama glama). However, the origin of the domestic species has been a matter of debate. In the present study, variations in chromosome G banding patterns and in two mitochondrial gene sequences have been used to study the origin and classification of the llama and alpaca. Similar patterns in chromosome G band structure were observed in all four Lamini species, and these in turn were similar to the bands described for camels, Camelus bactrianus. However, fine and consistent differences were found in the short arms of chromosome 1, separating camels, guanacos and llamas from vicunas and alpacas. This pattern was consistent even in a hybrid guanaco x alpaca. Equivalent relationship showed the complete cytochrome b gene sequences, and the minimum expansion tree of the partial control region sequence, grouping guanaco with llama and vicuna with alpaca. Phylogenetic analyses showed V. vicugna and L. guanicoe as monophyletic groups. Analysis of both gene sequences revealed two clades within vicuna, concordant with the two described subspecies, but the results for guanaco did not confirm existence of the four previously proposed subspecies. The combined analysis of chromosomal and molecular variation showed close genetic similarity between alpacas and vicunas, as well as between llamas and guanacos. Although directional hybridization was revealed, our results strongly support the hypothesis that the llama would have derived from L. guanicoe and the alpaca from V. vicugna, supporting reclassification as V. pacos.

Abstract: The vicuna (Vicugna vicugna; Miller, 1924) is a conservation success story, having recovered from near extinction in the 1960s to current population levels estimated at 275 000. However, lack of information about its demographic history and genetic diversity has limited both our understanding of its recovery and the development of science-based conservation measures. To examine the evolution and recent demographic history of the vicuna across its current range and to assess its genetic variation and population structure, we sequenced mitochondrial DNA from the control region (CR) for 261 individuals from 29 populations across Peru, Chile and Argentina. Our results suggest that populations currently designated as Vicugna vicugna vicugna and Vicugna vicugna mensalis comprise separate mitochondrial lineages. The current population distribution appears to be the result of a recent demographic expansion associated with the last major glacial event of the Pleistocene in the northern (18 to 22 degrees S) dry Andes 14-12 000 years ago and the establishment of an extremely arid belt known as the 'Dry Diagonal' to 29 degrees S. Within the Dry Diagonal, small populations of V. v. vicugna appear to have survived showing the genetic signature of demographic isolation, whereas to the north V. v. mensalis populations underwent a rapid demographic expansion before recent anthropogenic impacts.

Abstract: In the present work, polymerase chain reaction-single strand conformation polymorphism and sequencing were used to investigate the length and nucleotide variability in the Control Region mitochondrial DNA of the four South American camelid species from Argentina. To asses these the complete Control Region of 20 animals, 5 each of guanaco, llama, alpaca and vicuna species were cloned. Seventy-three clones corresponding to the 20 animals were screened and 7 different SSCP patterns were identified. Sequencing of all clones showed 9 different haplotypes contained in the 350 bp hypervariable segment of the Control Region. Interestingly, 3 guanacos, 3 vicunas, 3 alpacas and 1 llama were heteroplasmic for different nucleotide positions. The screening of the Control Region mitochondrial DNA in blood samples from about 200 wild guanacos from Argentine Patagonia supported the above results. After comparison with other vertebrate species, we concluded that nucleotide substitutions are the main cause of heteroplasmy found in Control Region mitochondrial DNA of these taxa.

Sahley, Catherine Teresa; Vargas, Jorge Torres; Valdivia, Jesus Sanchez. Biological sustainability of live shearing of vicuna in Peru. Conservation Biology. 2007 Feb; 21(1): 98-105. ISSN: 0888-8892
NAL call no.: QH75.A1C5
Abstract: The vicuna's (Vicugna vicugna) fiber is highly valued as an export product that is made into luxury fabric and clothing. The price of fiber in 2004 was $566/kg, which makes the fiber a potentially important source of income for Andean agropastoral communities and serves as an incentive to allow vicuna grazing on high-elevation Andean landscapes. It is presumed that a shorn vicuna has little value for poachers, so shearing vicunas could serve as a disincentive to poaching. Thus, the supply of vicuna fiber may be sustainable if it is procured through live shearing, which should serve as a powerful conservation tool. We evaluated the effects of capture and shearing on the demography of vicuna in one site located in the Salinas Aguada Blanca Reserve, Arequipa, Peru, where vicunas were captured and shorn in spring and then returned to the wild. We conducted fixed-width line-transect censuses from 1997 to 2003 of this population. We compared the proportion of young born to females that were shorn versus females that were unshorn for the 3 years in which shearing occurred. We evaluated the effect of capture and shearing on proportion of young born to shorn and unshorn females at a second site, Picotani, Puno. The wild population in Arequipa that underwent capture and shearing showed a steady increase in total population and average density between 1997 and 2003. No significant difference was found between the proportion of young per female for shorn and unshorn females at either site. We conclude that in spring, capture and live shearing of vicunas can be biologically sustainable. Further research is needed to determine whether shearing during winter months is biologically sustainable.

Abstract: The aim of this study was to investigate the participation of Neospora caninum and Toxoplasma gondii in abortion cases of Peruvian llamas and alpacas. Fifteen aborted foetuses were recovered from two main rearing areas of camelids in Peru (Central or South Andean region). Foetal histopathology was used to detect the presence of protozoal-associated lesions in target organs. N. caninum and T. gondii infections were confirmed by immunohistochemistry (IHC) combined with PCR and by PCR alone, respectively. The influence of the species (llama and alpaca), foetal age (first, second and third gestational periods) and geographical location (Central or South Andean region) of the foetuses was also studied. Thirteen of the samples (26%, 13/50) showed lesions suggestive of protozoal infection. N. caninum infection was detected by either IHC or specific PCR in 14 out of 50 foetuses (28%), of which 8 also showed protozoal-associated lesions. T. gondii DNA was not detected in any of the foetuses analysed. Protozoal infection was more frequent in the foetuses from the second gestational period (P<0.05, Fisher F-test). No significant association was observed between protozoal infection and species or geographical location (P>0.05, chi 2 test). The results of the present study indicate that neosporosis should be included during the differential diagnosis of abortion in llamas and alpacas.

NAL call no.: SF380.I52
Abstract: The isthmus and uterotubal junction (UTJ) from oviducts of adult female vicunas (Vicugna vicuna) were used to study the epithelial cell ultrastructure. Scanning microphotographs revealed a mosaic pattern made up of ciliated and secretory cells with abundant microvilli. In the isthmus only a few secretory cells were present, scattered among numerous ciliated cells while in the UTJ the secretory cells prevail. The abundance of secretory cells suggests that the UTJ cells may possess special characteristics for sperm binding. No studies exist in either the vicuna or any of the other South American Camelids (SAC) concerning carbohydrates involved in sperm or embryo interactions on the oviductal surface. Identification of these sugars seems relevant to the mechanism involved in the sperm-oviduct interaction. As a first step in the determination of the molecular mechanism implicated in the formation of sperm reservoirs in the oviduct, lectin affinity for the oviductal mucosa was studied. High concentrations of glycosaminoglycans inside the two types of epithelial cells, and on their glycocalyx were observed with histochemical methods. The carbohydrates on the epithelial surface were labeled with fluorescent by lectins and analyzed with confocal scanning microscopy. The cell surface showed abundant l-mannopyranosyl, l-glucopyranosyl, o-galactosyl, N-acetyl glucosamine, and N-acetylneuraminic acid residues and few l-linked N-acetyl galactosamine residues. Neither l-l-fucopyranosyl nor o-N-acetyl galactosamine residues were observed in any part of the oviduct. The distinct ultrastructural characteristic of the UTJ as well as the presence of high concentrations of sugar residues on the mucosa surface of this portion of the oviduct could be related to its function as a sperm reservoir.

DOI : http://dx.doi.org/10.1017/S0030605306000639
Abstracts: Vicuna Vicugna vicugna are an emblematic species of one of the major arid ecosystems of the neotropics: the puna or altiplano. Excessive commercial hunting of vicuna for their valuable fleece in the past caused a severe decline in the population, with the vicuna almost becoming extinct by the mid 20th century. Effective protection resulted in the recovery of some populations and, recently, limited vicuna exploitation has been allowed. Research is urgently required to underpin the design of the management systems used for this exploitation. We present the results of a 2-year study on habitat utilization of vicuna in Laguna de Pozuelos UNESCO Biosphere Reserve in Argentina. Vicuna did not use the study area homogeneously but preferred vegetation communities dominated by grasses (known locally as pajonal and esporal) and with high overall plant cover. Vicuna were less selective in 2003, when overall habitat quality decreased, than in 2002. This change is predicted by habitat selection theory. We also found that members of family groups spend more time foraging than members of non-reproductive groups. Solitary vicuna spend more time standing up than members of groups, consistent with the observation that herding behaviour is related to protection against predators. Heterogeneous use and habitat selectivity suggest that exploitation of vicuna needs to take spatial behaviour into account in the establishment of the optimal location of capturing sites.

Abstract: The current program of vicuna conservation includes their live-capture for wool harvest in the Andes Region in northern Chile. Here, we describe studies that assess the impacts on the species of different variables relating to the capture process. The immediate physical and physiological effects on vicuna of contrasting capture methods, chase distances and restraint were measured. Comparisons between two methods of capture showed that cortisol concentrations were higher in animals herded using vehicles alone compared to those herded using a combination of vehicles and local people on foot. Blood glucose levels, heart rate and respiratory rate showed an immediate but ephemeral response to herding into a corral. The range of distances over which animals were herded caused less noticeable changes in blood and physical parameters. The most marked changes were associated with restraint, during which there were significant increases in creatine kinase, packed cell volume and rectal temperature. The implications of changes in these parameters on vicuna welfare and conservation are discussed.

Abstract: Antibodies are glycoproteins comprising two heavy and two light chains. Surprisingly, all members of the family Camelidae possess a fraction of antibodies devoid of both light chains and the first constant domain (CH1). These kinds of antibodies are known as heavy chain antibodies (HCAbs). There are three subclasses of IgG in dromedaries, namely IgG(1), IgG(2) and IgG(3) Of which, IgG(2) and IgG(3) are of the HCAbs type. In the present work, the different IgG isotypes from guanaco (Lama guanicoe), llama (Lama glama) and vicuna (Vicugna vicugna) were purified and characterized. Interestingly, it was found that IgM was capable of binding to protein A. The different subclasses of immunoglobulins were also assayed for their ability to fix complement. Both IgG(1) and the total serum were able to fix complement, whereas IgG(2) and IgG(3) fixed complement even in the absence of antigen. (c) 2005 Elsevier B.V. All rights reserved.

Abstract: Environmental enrichment by increasing foraging behaviour and providing food item choice are widely practised and generally accepted as effective methods for reducing stereotypic behaviour in captive animals. In this study, the effectiveness of increasing foraging patch choice and food item choice on reducing motor stereotypy in two captive vicugna were examined. For the purposes of the study, first, browse was added to the vicugna's enclosure as an additional forage item and, second, the vicugna's normal feed was divided: half being provided in the indoor quarters and half in the outdoor yard. The results revealed that providing browse as an additional forage item increased the observed stereotypic behaviour; however, dividing the vicugna's feed, and therefore increasing forage patch choice, decreased stereotypy. This study was limited because of the small sample size and because the area in which the vicugna were performing stereotypic behaviour was partially visually obscured. However, this study has implications for animal welfare because it highlights the need to evaluate the suitability of foraging enrichment items, and suggests that more research into accommodating the adaptive foraging behaviour of this species in captivity may be necessary.

NAL call no.: QP251.A5
Abstract: The aim of the present study was two-fold. First, to evaluate the effect of exogenous progesterone on ovarian follicular dynamics in order to assess its ability to synchronize ovarian activity in the vicuna. Secondly, to evaluate the ovarian response to the treatment with eCG through the observation of the structures developed in the ovaries. Follicular dynamics was monitored daily by transrectal ultrasonography in 12 adult, non-pregnant vicunas. Plasma progesterone and estradiol-17 beta concentrations were measured in blood samples collected daily. In experiment 1, intravaginal devices containing 0.33 g of progesterone were inserted into the vagina and kept in place for 5 days (treatment group, n=8). After progesterone withdrawal, five animals were further monitored in order to evaluate the efficacy of the CIDRReg. to synchronize the emergence of a dominant follicle. In experiment 2, four females received 750 IU of eCG IM. Two were previously monitored ultrasonographically to confirm the absence of a dominant follicle at the beginning of the superstimulatory treatment (group A). The other two animals had a CIDRReg. inserted into the vagina for 5 days and the superstimulatory treatment was applied 24 h after device withdrawal (group B). Females from both groups were surgically explored 96 h after eCG injection; the ovaries were exposed and the number of newly formed structures produced by each ovary was counted. Peak progesterone concentrations (25.9+or-5.29 nmol l-1, mean+or-S.E.M.) were attained on day 1 after device insertion, remained high until the day of device withdrawal (9.7+or-1.98 nmol l-1) and decreased to 5.5+or-1.13 nmol l-1 the day after. There was no follicle development to the state of dominance after device insertion. Moreover, mean follicle diameter steadily decreased after insertion of the device until the minimum mean value (1.85+or-0.17 mm) was recorded on day 5 (P=0.006). Similarly, plasma concentrations of estradiol-17 beta remained below 35 pmol l-1 during the period of progesterone treatment in all animals and the mean estradiol-17 beta declined with the lowest value (22.1+or-2.19 pmol l-1) being recorded on day 4 after device insertion. After superstimulation of follicular development with eCG, the total number of follicles that developed was 33 in group A and 58 in group B and the mean number of newly developed ovarian structures per female was 22.75+or-4.26. In conclusion, progesterone released by the CIDRReg. exerts a negative effect on ovarian follicular development and function suggesting intravaginal devices could be used to synchronize the beginning of follicular waves during a superstimulatory treatment. There was also a tendency for greater ovarian follicular development when the animals were previously treated with progesterone.

Abstract: The vicuna (Vicugna vicugna) is a rare species of the camel family that is related to the llama and is found only in the high Andes. It is exploited for its wool. This article discusses the future of the species in Chile, where it has been protected and managed for 30 years. The discussion is with reference to proposals for management of the animal for the commercialization of its wool in the Region of Tarapaca, under the aegis of the Ministry of Agriculture (MINAGRI) and CONAF. These bodies have put forward various strategic plans of action for the conservation and management of the species, both in the wild and in captivity and these are outlined, along with analyses of the market and demand for the animalAEs wool.

Abstract: A method for the determination of clean down yield and quality (mean fiber diameter and distribution of down fibers) in fleece samples with heterogeneous fibers without its separation is described. The method is based on clean yield determination followed by subsampling using the Minicore equipment and automatic measurement of fiber diameter of a large number of fibers using the Laserscan equipment. Applying the criterion that down fibers have a fiber diameter equal or below 30 micro and hair fibers above that value and using the resulting mean fiber diameter, standard deviation and density of both types of fibers in the Wildman formula it is possible to determine down yield accurately and quickly. Predicted down yield in vicuna fleece samples with known yield adjusted to 99%, independently of density of fibers assumed. Predictions which consider fiber length did not improve the adjustment. The method is proposed for routine analyses of South American Camelid individual fleece samples.

Abstract: The highlands of South America form a special ecosystem with an important biodiversity. Since 4 000 or 5 000 years ago, two species of domesticated camelids have developed in this region: the llama and the alpaca, as well as two non-domesticated ones, the guanaco and the vicuna. During the Incas period, these genetic resources played an important role in the development of this ancient culture, but the protagonistic role of Camelids ended abruptly with the Spanish conquest of that South American region five centuries ago. The Spaniards initiated their colonization with the systematic elimination of the camelids and replaced them with their own domestic species, principally sheep and cattle. Along with the Spanish conquest, the mines period begins in these highlands as well; the mines' development requested not only an important quantity of camelids' meat, vegetables and natural energy but also large llama caravans, in order to transport the mines products from highlands to the coast. However, the pastoral communities in those high-risk environments have played a major role in conserving the llama, alpaca, guanaco and vicuna species. The mining activity along with human pressure on the fragile ecosystem resulted not only in an important loss of biodiversity but also, and most importantly, in the reproduction of poverty. Consequently, today like five centuries ago, the highlands of South America are characterized by three elements: poverty, soils of low quality and camelids. And it is through these elements that they try to resolve their main problem, that is poverty. The analysis of market trends, the review of the historical context of the use of native breeds, and the efforts of highlands people suggest that the rational use of South American Camelids, both domestic and wild ones, can be an economic alternative in many production systems in the South American highlands, on the condition that the regional governments in co-operation with the producers are able to find new markets with fair prices and improve the quality of camelids' products.

Abstract: The objective of the present study was to characterize ovarian activity in non-mated vicunas, relating ovarian structures (evaluated by transrectal ultrasonography, daily for 30 days) to changes in plasma concentrations of estradiol-17beta and progesterone. Ovarian follicular activity occurred in waves, characterized by the follicle emergence, growth and regression. The mean duration of follicular waves was 7.2 +/- 0.5 days (mean +/- S.E.M.), with a range of 4-11 days. The follicular growth phase averaged 3.0 +/- 0.2 days, the static phase 1.4 +/- 0.1, the regression phase 2.9 +/- 0.3 days, and the inter-wave interval was 4.2 +/- 0.3 days. The mean growth rate during the growing phase was 1.8 +/- 0.1 mm/day, while the duration of the interval from 6 mm to maximum diameter was 1.4 +/- 0.1 days. The mean maximum diameter of the dominant follicle was 8.4 +/- 0.3 mm (range: 6.2-11.2) and mean diameter of the largest subordinate follicle was 5.4 +/- 0.1 mm. There was an inverse relationship between the size of the largest follicle and the total number of follicles (r = -0.21, P = 0.002). Follicle activity alternated between ovaries in 77% of the waves, with 40% of dominant follicles present in the left ovary and 60% in the right ovary. Plasma estradiol-17beta concentrations also had a wave-like pattern, varying between 12.0 and 62.8 pmol/l. Plasma progesterone concentrations remained below 5.0 nmol/l and there was no ultrasonographic evidence of ovulation during the study.

Abstract: In the landscapes of the high plains at over 4 000 meters above sea level, thousands of years ago the Incas domesticated two species of the South American camelids: Alpaca and Llama, using techniques that are a mystery to these days. The first one would later be used as a source of soft, fine and resistant fibre and the second one as a mean of transportation. From the two species that continued being wild: Guanaco and especially Vicuna, a fantastic and very fine fibre was obtained, which was reserved only for nobility. Its threads were mixed with gold threads to create varied work of art. It was the fibre of the gods. Reproduced with permission of CAB Abstracts.

Abstract: Based on a sample of 53 faeces, the diet of Puma concolor [Felis concolor] was studied in a protected area of the Bolivian altiplano. The largest contribution to the diet in number of preys came from medium and small rodents (98%), but camelids made up the main contribution in biomass (53%), corresponding little more than half to domestic species and the rest to Vicugna vicugna. Our results disagree with the hypothesis that pumas feed mainly on those prey most available in its environment, because it seems to prefer vicunas over livestock. However, our estimate of the quantity of livestock consumed suggests that a program of control of puma predation should be started urgently, to avoid larger management problems between the protected area's administration and local inhabitants.

Sahley, C.; Torres, J.; Sanchez, J. Neoliberalism meets pre-Columbian tradition: campesino communities and vicuna management in Andean Peru. Culture and Agriculture. 2004; 26(1/2): 60-68. ISSN: 1048-4876
Abstract: This paper first presents a brief history of vicuna conservation efforts in Andean Peru, and then focuses on tracing legal, biological, and social developments from the mid-1990s to the present. It also points out the importance of the vicuna as an ancient, as well as current, symbolic or archetypal species for Andean communities, and the importance of the human-vicuna interaction for the conservation of the vicuna. Finally, the paper makes recommendations for enhancing the conservation prospects for the vicuna. The paper places special emphasis on the importance of conserving the vicuna as a wild mammal, and argues that legislation to conserve it should prioritize the species' biological needs as well as the needs of Andean campesino communities whose land they inhabit. It is argued that because vicunas are a wild species, legislation should not address them as if they were domestic livestock, even though they now form part of Andean communities' livelihood strategies and "livestock portfolio".
