background: multidrug resistance in salmonella enteritidis isolates is a public health problem worldwide; the present study, therefore, was designed for antimicrobial-resistance determination in this strain. methods: salmonella strains isolated from poultry samples by biochemical positive and negative tests were subjected to pcr and identified as salmonella enteritidis. for detection and identi...

In the present study, a series of experiments were conducted to evaluate the ability of a combination of 3 ATCC lactobacilli (LAB3) or a commercially available probiotic culture (PROB) to reduce Salmonella enterica serovar Enteritidis (Salmonella Enteritidis) in broiler chicks. Additionally, we varied the timing of PROB administration in relationship to Salmonella challenge and determined the i...

The objectives of this study were to enumerate Salmonella enterica serovar Enteritidis colonization in fecal, cecal, and internal organs, and to compare the level of virulence gene expression (hilA) of experimentally challenged laying hens fed different dietary molt-induction regimens. Twelve Salmonella-free Single Comb Leghorn hens (>50 wk old) hens were randomly assigned to each of 6 treatmen...

We evaluated the effect of a Lactobacillus-based probiotic culture (FM-B11) for reduction of Salmonella Enteritidis in neonatal broiler chicks. In all experiments, chicks were challenged with approximately 10(4) cfu of Salmonella Enteritidis upon arrival at our laboratory, and the treatments were administered 1 h postchallenge. Cecal tonsil samples were obtained 24 h posttreatment and enriched ...

Salmonella Enteritidis is one of the agents that is responsible for outbreaks of human foodborne salmonellosis caused by Salmonella Enteritidis and is generally associated with the consumption of poultry products. Inactivated Salmonella Enteritidis cell vaccine is one of the available methods to control Salmonella Enteritidis in breeders and laying hens, however results in terms of efficacy var...

this study was conducted to investigate the effect of bacillus subtilis and licheni formis on broiler breeder performance and gastrointestinal health of their progenies. a total of 336 broiler breeder hens (cobb 500) from 22 to 32 weeks of age were used in a completely randomized design of 2 × 2 factorial arrangement with four treatments, each with seven replicates. dietary treatments included:...

Background and Aim: Ciprofloxacin-resistant Salmonella spp. are among the most important causative agents of food-borne infections. The marA efflux pump in this bacterium plays a significant role in the development of drug resistance. The aim of this study was to investigate marA efflux pump gene expression in Ciprofloxacin resistant Salmonella enteritidis clinical strains by Real Time PCR. Mat...

We investigated the efficacy of feed supplemented with caprylic acid (CA), a natural, 8-carbon fatty acid for reducing Salmonella enterica serovar Enteritidis colonization in commercial broiler chickens. In separate 3- and 6-wk trials, 1-d-old straight-run broiler chicks (n = 70 birds/trial) were assigned to a control group (challenged with Salmonella Enteritidis, no CA) and 2 replicates of 0.7...
