Salmonella is a major zoonotic foodborne pathogen that persists on poultry farms worldwide. The present study aimed to survey the prevalence of and antimicrobial resistance enterica serovar Enteritidis (S. Enteritidis) recovered from broiler chickens in Shandong Province, China. A total 280 isolates were identified 923 chicken samples between 2013 2018. Among isolates, S. (n = 128, 45.7%) was p...

the purpose of this study was to survey infections with salmonella spp. in poultry flocks in the vicinity of tehran and to determine the most frequent serogroups and serotypes implicated. twenty-eight samples of pullet, layer, and broiler flocks were randomly collected (n=1463), including freshly dropped feces from live birds or visceral organs from dead birds. in most flocks, 60 samples were t...

this survey of salmonella and specifically salmonella enteritidis contamination in broiler flocks carried out in amol as one of the most important poultry breeding centers, used as manure, yolk sac, papers and visceral organs from dead birds. standard cultural methods were used for salmonella isolation. slide agglutination or tube agglutination tests were erformed using salmonella somatic o pol...

Poultry is a major reservoir for foodborne Salmonella serovars. Salmonella Typhimurium, Salmonella Enteritidis, Salmonella Heidelberg, Salmonella Kentucky, and Salmonella Senftenberg are the most prevalent serovars in U.S. poultry. Information concerning the interactions between different Salmonella species and host cells in poultry is lacking. In the present study, the above mentioned Salmonel...

The effect of colistin sulfate on reducing Salmonella enteritidis (S.enteritidis) infection in broilers and contamination from broiler carcasses was evaluated. 40000 birds in two separate houses were considered. Colistin sulfate was added in to the feed of the test group as 100g containing 1,200,000IU/ton of feed for the whole period (56 days). To isolate S.enteritidis, samples were taken from ...

US Department of Agriculture Food Safety and Inspection Service (FSIS) data on Salmonella enterica serotype Enteritidis in broiler chicken carcass rinses collected from 2000 through 2005 showed the annual number of isolates increased >4-fold and the proportion of establishments with Salmonella Enteritidis-positive rinses increased nearly 3-fold (test for trend, p<0.0001). The number of states w...

Toll-like receptors (TLR) recognize evolutionarily conserved molecular motifs (pathogen-associated molecular patterns) of infectious microbes and initiate innate immune response upon activation with relevant pathogens. This study investigated the acute effect of Salmonella Enteritidis challenge on TLR mRNA expression in cecum and spleen of birds from 3 distinct genetic lines. Chicks from broile...
