Mitigation of Salmonella associated with poultry carcasses is primarily accomplished by rendering or carcass composting. While rendering temperatures and pressures are well established for pathogen inactivation in poultry carcasses, parameters controlling composting processes are less defined in part because multiple conditions and procedures are utilized. Consequently, limited knowledge exists...

Two experiments evaluated prebiotics added to feed on the recovery of Salmonella in broilers during grow-out and processing. In Experiment 1, "seeder" chicks were inoculated with Salmonella Typhimurium and placed with penmates. Treatments were: basal control diet, added 0.3% bamboo charcoal, 0.6% bamboo charcoal, or 0.12% Aromabiotic (medium chain fatty acids). The ceca from seeders and...

While horizontal transmission is a route clearly linked to the spread of Campylobacter at the farm level, few studies support the transmission of Campylobacter spp. from breeder flocks to their offspring. Thus, the present study was carried out to investigate the possibility of vertical transmission. Breeders were monitored from the time of housing day-old chicks, then throughout the laying...

Publication date: September 2016 , Volume 67 Author(s): J. Brändle, K.J. Domig, W. Kneifel Via butyric acid fermentation, clostridia – mainly Clostridium tyrobutyricum – are able to transform lactic acid into butyric acid, acetic acid and gas (H2 and CO2). The presence of clostridial endospores in milk may lead to severe quality defects in semi-hard and hard cheeses. As a consequence of...

Jie Ren, Yu Sang, Yongcong Tan, Jing Tao, Jinjing Ni, Shuting Liu, Xia Fan, Wei Zhao, Jie Lu, Wenjuan Wu, Yu-Feng Yao The two-component system PhoP-PhoQ is highly conserved in bacteria and regulates virulence in response to various signals for bacteria within the mammalian host. Here, we demonstrate that PhoP could be acetylated Pat and deacetylated deacetylase CobB enzymatically in vitro and in...

Summary Listeria monocytogenes FrvA (Lmo0641) is critical for virulence in the mouse model and is an ortholog of the Bacillus subtilis Fur- and PerR-regulated Fe(II) efflux P1B4-type ATPase PfeT. Previously, FrvA was suggested to protect against heme toxicity. Here, we demonstrate that an frvA mutant is sensitive to iron intoxication, but not to other metals. Expression of frvA is induced by high...

Publication date: Available online 4 March 2016 Author(s): Megan E. Meek, Frances M. Van Dolah Abstract Phytoplankton rarely occur as unialgal populations. Therefore, to study species-specific protein expression, indicative of physiological status in natural populations, methods are needed that will both assay for a protein of interest and identify the species expressing it. Here we...

Abstract This study developed growth/no growth models to describe the effect of NaNO2 and NaCl on Enterococcus growth. Enterococcus spp. were incubated in deMan, Rogosa and Sharpe broth formulated with NaNO2 (0–210 ppm) and NaCl (0–1.75%) at 4–15C up to 1,080 h under aerobic and anaerobic conditions. Growth responses (growth: 1 or no growth: 0) for all the combinations were collected. The growth...

Marta I. Sánchez, Inès Pons, Mónica Martínez-Haro, Mark A. Taggart, Thomas Lenormand, Andy J. Green Parasites and pollutants can both affect any living organism, and their interactions can be very important. To date, repeated studies have found that parasites and heavy metals or metalloids both have important negative effects on the health of animals, often in a synergistic manner. Here, we show...

Recently, the plasmid-mediated colistin resistance gene mcr-1 was found in Enterobacteriaceae from humans, pigs and retail meat in China. Several reports have documented global presence of the gene in Enterobacteriaceae from humans, food animals and food since. We screened several well-characterised strain collections of Enterobacteriaceae, obtained from retail chicken meat and hospitalised...

Hui Sun, Jana Kamanova, Maria Lara-Tejero, Jorge E. Galán Microbial infections usually lead to host innate immune responses and inflammation. These responses most often limit pathogen replication although they can also result in host-tissue damage. The enteropathogenic bacteria Salmonella Typhimurium utilizes a type III secretion system to induce intestinal inflammation delivering specific...

Abstract Intentional food crime is plural in nature in terms of the types of crime and the differing levels of financial gain. Successful models of food crime are dependent on how well the crime has been executed and at what point, or even if, detection actually occurs. The aim of this paper is to undertake a literature review and critique the often contradictory definitions that can be found in...

Summary In Salmonella enterica and related species, translation elongation factor EF-Tu is encoded by two widely separated but near-identical genes, tufA and tufB. Two thirds of EF-Tu is expressed from tufA with the remaining one third coming from tufB. Inactivation of tufA is partly compensated by a doubling in the amount of EF-TuB but the mechanism of this up-regulation is unknown. By...

This study was undertaken to study acrylamide formation during deep-fat frying of ripe and unripe banana chips at 150, 170 and 190C up to 360 s. The moisture content, oil content, color and texture of the fried chips were also monitored during frying. The acrylamide formation was higher in ripe banana chips than unripe banana chips at all temperatures of frying. Acrylamide formation followed...
