Transboundary and Emerging Diseases, Volume 69, Issue 5, Page 2544-2558, September 2022. Poultry and poultry-derived products such as meat and eggs are among the main sources of non-typhoidal Salmonella (NTS) transmission to humans.

Transboundary and Emerging Diseases, Volume 69, Issue 4, Page 1847-1861, July 2022. Campylobacter jejuni (C. jejuni), is considered among the most common bacterial causes of human bacterial gastroenteritis worldwide. The epidemiology and the transmission dynamics of campylobacteriosis in Egypt remain poorly defined due to the limited use of high-resolution typing methods.

Transboundary and Emerging Diseases, Volume 69, Issue 4, Page e693-e703, July 2022. Vibrio cholerae O1 El Tor variants have been the major causative agents of cholera worldwide since their emergence in the 2000s. Cholera remains endemic in some regions in Malaysia. Therefore, we aimed to investigate the genetic characteristics of the V.

Transboundary and Emerging Diseases, Accepted Article. The primary goals of this cross-sectional study were to screen various food/water, and human samples for the presence of Salmonella species, and to assess the phenotypic and genetic relationship between resistances found in food and human Salmonella isolates to critically important antibiotics.

Transboundary and Emerging Diseases, Accepted Article. Campylobacter infection is an important cause of genital failure in ruminants in developed countries. Although historically Campylobacter fetus subspecies fetus has been the main cause of abortion in sheep, C. jejuni is also increasingly associated with sheep abortions.

Transboundary and Emerging Diseases, Accepted Article. Live bird markets (LBMs) provide integral hubs for 95% of poultry produced for food. Surveillance systems in LBMs serving smallholder farmers in sub-saharan Africa are often non-functional and data about public health risks and emerging pathogens are lacking. Studies in Kenya have reported 29% – 44% Campylobacter-prevalence in poultry.

Transboundary and Emerging Diseases, Accepted Article. Staphylococcus aureus is a pathogen that can affect multiple host species. Evidence of transmission between humans and animals and among different animal species has been reported in recent years. In this study, we investigated 284 free-living red deer (Cervus elaphus) in the Central Italian Alps to assess the prevalence and molecular characteristics of S.

Transboundary and Emerging Diseases, Accepted Article. Antimicrobial resistance (AMR) is a global concern and controlling its spread is critical for the effectiveness of antibiotics. Members of the genus Salmonella are broadly distributed, and wild boar may play an important role in its circulation between peri-urban areas and the environment, due to its frequent interactions both with livestock or human garbage.

Transboundary and Emerging Diseases, Accepted Article. Brucellosis is a zoonotic and contagious infectious disease caused by Brucella spp, which causes substantial economic losses to animal husbandry and leads to severe public health problems. Brucella have evolved multiple strategies to escape host immunity and survive within host cells. Elucidating the immune evasion strategies during Brucella infection will facilitate the control of brucellosis.

Transboundary and Emerging Diseases, Accepted Article. Poultry and poultry-derived products such as meat and eggs are among the main sources of non-typhoidal Salmonella (NTS) transmission to the human.

Transboundary and Emerging Diseases, Accepted Article. Vibrio cholerae O1 El Tor variants have been the major causative agents of cholera worldwide since their emergence in the 2000s. Cholera remains endemic in some regions in Malaysia. Therefore, we aimed to investigate the genetic characteristics of the V. cholerae O1 El Tor strains associated with outbreaks and sporadic cases to elucidate the molecular evolution among the strains circulating in this region. A total of 45 V.

Transboundary and Emerging Diseases, Accepted Article. Campylobacter jejuni (C. jejuni), is considered among the most common bacterial causes of human bacterial gastroenteritis worldwide. The epidemiology and the transmission dynamics of campylobacteriosis in Egypt remain poorly defined due to the limited use of high-resolution typing methods. In this pilot study, we evaluated the discriminatory power of multiple typing ‘gene-by-gene based’ techniques to characterize C.

Transboundary and Emerging Diseases, Accepted Article. Coxiella burnetii causes coxiellosis in animals and Q fever in humans, a potentially debilitating zoonotic disease commonly transmitted through domestic ruminants. To prevent transboundary spread of C. burnetii, animals may be tested prior to export. In alpacas, this process is complicated by the lack of scientific evidence for C.

Shiga toxin‐producing Escherichia coli (STEC) is an important foodborne pathogen capable of causing severe gastrointestinal diseases in humans. Cattle and sheep are the natural reservoir hosts of STEC strains. Previously, we isolated 56 STEC strains from anal and carcass swab samples of cattle and sheep in farms and slaughterhouses.

Toxoplasma gondii may cause fatal infection in European brown hares (Lepus europaeus). However, the role of this parasite in terms of mortality rate in tularemia endemic areas, amount of parasites in affected organs and circulating genotypes, are still unknown. In total, 36 hares (killed or found dead) were submitted for pathomorphological examination as a part of the national tularemia and brucellosis monitoring.

Small ruminant brucellosis remains endemic in many low and middle‐income countries (LMICs), where it poses a major economic and public health burden. Lack of resources to support long‐term vaccination, inherent characteristics of small ruminant production systems such as mixing of different flocks for grazing and limitations of the vaccines currently available, which can induce abortion in pregnant animals, have all hindered the effectiveness of control programs.

Salmonellosis is one of the most important bacterial diseases in pigeons. This study aimed to estimate the prevalence of Salmonella spp. in domestic pigeons (Columba livia f. domestica) in Poland, its antimicrobial susceptibility (both phenotypic and genotypic), and its capability for biofilm formation. The presence of selected virulence genes, nucleotide homology of selected genes, and susceptibility to bacteriophages were investigated as well.

Porcine circovirus type 3 (PCV3) is considered a new circovirus and since it first description has been widely reported in most of the swine‐producing countries. Multisystemic inflammation and reproductive failure are consistent and concerning issues associated with PCV3 infection. This report describes the clinical and pathological features of a chronic reproductive disorder in a swine herd in Argentina associated with the presence of PCV3.

Mycobacterium (M.) bovis can infect cats and is a demonstrated zoonosis. We describe an outbreak of M. bovis in pet cats across England and Scotland associated with feeding a commercial raw food diet. Forty‐seven cats presented with (pyo)granulomatous lesions, lymphadenopathy, pulmonary and/or alimentary disease over a one‐year period where M. bovis infection was suspected or definitively diagnosed, and the cats all consumed the same specific brand of commercial raw venison pet food.

Brucellosis in small ruminants caused mainly due to Brucella melitensis is an important zoonotic disease characterized by abortion, retained placenta, infertility, orchitis, epididymitis, and rarely arthritis. Small ruminants are the main source of economy for the rural and marginally poor farmers and brucellosis is resulting in huge economic losses due to abortions and infertility and causing public health concern among the small ruminant keepers.
