S. typhimurium S. enteritidis S. Kentucky chicken meat MultiplexPCR The present study was conducted for identification of molecular characterization of Salmonella enterica isolated from chicken meat by using multiplex-PCR isolated from 200 samples of fresh chicken meat and 100 samples of ready to eat chicken meat. Samples were assessed by performing the pre-enrichment and enrichment culture, bi...

This study was carried out to investigate the presence of Salmonella sp in flocks of white laying hens. In different farms, the transport boxes of twelve flocks were inspected at arrival for the presence of Salmonella. Four positive (A, B, L and M) and one negative (I) flocks were monitored at each four weeks using bacteriological examination of cecal fresh feces up to 52 weeks. Birds were also...

Salmonella enterica is frequently associated with outbreaks of human salmonellosis, and products of avian origin, such as eggs and chicken meat, are the main vehicles of its transmission. The present study describes the occurrence of different serovars of Salmonella enterica and phagotypes of S. enterica serovar Enteritidis in eggs destined for human consumption. Four thousand eggs obtained fro...

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.

in diagnostic and research bacteriology settings with budget and staff restrictions, fast and cost-effective genome extraction methods are desirable. if not inactivated properly, cellular and/or environmental dna nucleases will degrade genomic material during the extraction stage, and therefore might give rise to incorrect results in pcr experiments. when crude cell extracts, proteinase k–treat...

A retrospective study that involves the analysis of laboratory diagnostic data collected during the period 1996-2006 was conducted. A total of 3417 Salmonella isolations involving 183 different serotypes was recorded from 1999-2006, inclusive, at the Onderstepoort Veterinary Institute, Agricultural Research Council, South Africa. The most common serotypes were Salmonella enterica subspecies ent...

Salmonella enterica subspecies enterica serotype Enteritidis is a major cause of egg-borne human salmonellosis. The ability to survive in egg albumen at chicken body temperature was hypothesized to be an important factor involved in the predominant contamination of eggs by this specific serotype. Eighty-nine Salmonella strains from different serotypes, belonging to 5 serogroups, were incubated ...

Salmonella enterica ssp. enterica serovar Typhimurium and Salmonella enterica ssp. enterica serovar Enteritidis are the major dominating serotypes of Salmonella in poultry and poultry products. Infection by Salmonella Typhimurium is an important cause of morbidity and mortality in poultry. Rapid differentiation of Salmonella Typhimurium from other Salmonella serotypes including Salmonella Enter...

A quantitative real-time PCR (qPCR) designed to detect Salmonella enterica subsp. enterica serovar Enteritidis, targeting the sdf gene, generated positive results for S. enterica subsp. enterica serovar Typhimurium (CFSAN033950) and S. enterica subsp. enterica serovar Nottingham (CFSAN006803) isolated from food samples. Both strains show pulsed-field gel electrophoresis (PFGE) patterns distinct...

We report the genome sequence of Salmonella enterica subsp. enterica serovar Give (CFSAN012622), isolated from imported chili powder in 2014. This genome contains genes previously reported to be specific only to S. enterica serovar Enteritidis. This strain shows a unique pulsed-field gel electrophoresis (PFGE) pattern clustering with serovar Enteritidis (JEG X01.0005).
