Background:Salmonella Enteritidis phage type 8 (PT8) is a major poultry-associated Salmonella strain implicated in foodborne outbreaks in the United States. We previously reported that two plant-derived compounds generally recognized as safe (GRAS), trans-cinnamaldehyde (TC), and eugenol (EG), significantly reduced S. Enteritidis colonization in broiler and layer chickens. To elucidate potentia...

Salmonella enterica subsp. enterica serovar Enteritidis emerged in the late 1980s as the most isolated Salmonella serovar worldwide. Here, we report the draft genomes of 256 S Enteritidis strains isolated from humans, food, chickens, and farm environments in Brazil. These draft genomes will help enhance our understanding of this serovar in Brazil.

The protective effect of hyperimmune IgY fraction of egg yolk prepared from hens hyperimmunized with multiple species of Eimeria oocysts on experimental coccidiosis was evaluated in young broilers. Chickens were continuously fed from hatch with a standard diet containing hyperimmune IgY egg yolk powder or a nonsupplemented control diet and orally challenged at d 7 posthatch with 5.0 x 10(3) spo...

The prevalence of Salmonella enterica serovar Enteritidis is gradually decreasing in poultry flocks in the EU, which may result in the demand for a vaccine that allows for the differentiation of vaccinated flocks from those infected by wild-type S. Enteritidis. In this study, we therefore constructed a (Salmonella Pathogenicity Island 1) SPI1-lon mutant with or without fliC encoding for S. Ente...

Background: Poultry products have been recognized as major sources of human gastrointestinal disease caused by Salmonella spp. and several outbreaks have been reported where eggs were the source of human infection. OBJECTIVES: This study was carried out to determine the prevalence of Salmonella spp. in the quail egg interior contents from retail stores of Semnan, Iran and to characterize the i...

Poultry meat and eggs contaminated with Salmonella enterica serovar Enteritidis or Salmonella enterica serovar Typhimurium are common sources of acute gastroenteritis in humans. However, the exact nature of the immune mechanisms protective against Salmonella infection in chickens has not been characterized at the molecular level. In the present study, bacterial colonization, development of path...

salmonella enterica is considered as one of the major pathogens in public health, worldwide. diseases caused by salmonella enterica serovars are especially prevalent in developing countries. it is one of the emerging pathogen in food-borne diseases, which is often found in contaminated chicken eggs. the aim of this study was to apply a pcr–rflp method using sau3ai and hhai restriction endonucle...

A microarray-assisted gene expression screen of chicken heterophils revealed glycogen synthase kinase-3β (GSK-3β), a multifunctional Ser/Thr kinase, to be consistently upregulated 30-180 min following stimulation with Salmonella enterica serovar Enteritidis (S. Enteritidis). The present study was designed to delineate the role of GSK-3β in regulating the innate function of chicken heterophils i...
