Salmonella enterica subsp. enterica serovar Typhimurium strain YU39 was isolated in 2005 in the state of Yucatán, Mexico, from a human systemic infection. The YU39 strain is representative of the multidrug-resistant emergent sequence type 213 (ST213) genotype. The YU39 complete genome is composed of a chromosome and seven plasmids.

The objective of this research was to determine whether variation in the presence of fimbrial protein SefD would impact efficacy of bacterins as measured by recovery of Salmonella enterica serovar Enteritidis (Salmonella Enteritidis) from the spleens of hens. Two bacterins were prepared that varied in SefD content. Also, two adjuvants were tested, namely, water-in-oil and aluminum hydroxide gel...

Foodborne diseases caused by Salmonella enterica serovar Enteritidis (S. Enteritidis) are a significant health problem. Pregnancy, state of immunological tolerance, is a predisposing condition for the development of infections with intracellular pathogens. Salmonella species can cause pregnancy complications such as chorioamnionitis, transplacental fetal infection, pre term labor, abortions, ne...

Salmonella spp are among the main causative agents of foodborne diseases. Some phenotypes associated with increased drug resistance and virulence are regulated by quorum sensing (QS). In the present study, the autoinducer (AI)-1- and -2-mediated QS mechanisms were characterized in Salmonella enterica serovar Enteritidis PT4 for the first time. Salmonella Enteritidis did not produce AI-1. Phylog...

UNLABELLED To assess diversity of Salmonella enterica serotypes present in poultry and their environment from southern Brazil, the Kauffmann-White-Le Minor (KWL) scheme was used to serotype a total of 155 isolates. Isolates were then re-examined with nested PCR and sequencing of the dkgB-linked intergenic sequence ribotyping (ISR) region that assesses single nucleotide polymorphisms occurring a...

background and objectives : salmonella is one of the leading causes of food-borne diseases. increasing occurrence of antimicrobial resistance, especially multidrug-resistance, in salmonella serovars is a major public health problem worldwide. this study was carried out to detect class i integrons and antibiotic resistance profiles in clinical isolates of salmonella serovars collected from seven...

An asd-deleted (Deltaasd) mutant of Salmonella enterica serovar Pullorum (SP) was constructed using an improved method of gene knockout by combining the pi-suicide plasmid system with the Red Disruption system. The asd gene was efficiently knocked out by the recombinant suicide vector, which replaced the asd gene with the CmR gene. Based on the balanced lethal host-vector system, the phenotype ...

Salmonella enterica subsp. enterica serovar Thompson strain RM6836 was isolated from lettuce in 2002. We report here the complete sequence and annotation of the genome of S. Thompson RM6836. This is the first reported complete genome sequence for S. Thompson and it will enhance our understanding of this serovar and provide another point for comparative studies between Salmonella enterica strains.

We report the draft genomes of four Salmonella enterica isolates evaluated for the contribution of plasmids to virulence. Strains SE163A, SE696A, and SE710A carry plasmids demonstrated to facilitate plasmid-associated virulence, while SE819 is less virulent and has been used as a recipient for conjugation experiments to assess plasmid-encoded virulence mechanisms.

Here, we report a 4.87-Mbp draft genome sequence of the multidrug-resistant (MDR) Salmonella enterica subsp. enterica serovar Bardo strain CRJJGF_00099, isolated from dairy cattle in 2005.
