The type III secretion system (TTSS) encoded by Salmonella enterica serovar Typhimurium pathogenicity island 2 (SPI2) is employed by Salmonella enterica for interaction with host cells during the intracellular phase of pathogenesis. This TTSS secretes a set of SPI2-encoded proteins in vitro and translocates Salmonella serovar Typhimurium translocated effectors (STE) that are encoded by genes ou...

We announce the draft genome sequence of Salmonella enterica subsp. enterica serovar Manhattan strain 111113, isolated from a patient during an outbreak in northern Italy. The genome, which was obtained with Illumina MiSeq technology, is composed of 21 contigs for a total of 4,684,342 bp, with a G+C content of 52.17%.

Salmonella enterica serovar Typhimurium (S. Typhimurium) is a common cause of gastroenteritis in humans. Here, we report the draft genome sequences of 10 isolates of an S. Typhimurium phage type 135 variant that is linked to egg-associated outbreaks in Tasmania, Australia.

The sequences of nine genomes of Salmonella enterica serovar Bovismorbificans were compared to study the diversity and distribution of this emerging virulent serovar. These whole-genome sequences fill some gaps in knowledge of the diversity of the isolates used in this investigation.

In several bacterial systems, mutant cell populations plated on growth-restricting medium give rise to revertant colonies that accumulate over several days. One model suggests that nongrowing parent cells mutagenize their own genome and thereby create beneficial mutations (stress-induced mutagenesis). By this model, the first-order induction of new mutations in a nongrowing parent cell populati...

In this study, we assessed the presence of IS26 in food-borne ASSuT-type Salmonella enterica isolates. A new genetic region (R3) was described, that included a C14 caspase gene between IS26 elements. R3 was present in two Salmonella Rissen isolates from a swine carcass and a meat handler, collected at the same abattoir. Furthermore, a new rearrangement of resistance region R1, harboring the bla...

The genome of Salmonella enterica subspecies enterica serovar Enteritidis phage type 8 strain EN1660, isolated from an outbreak in Thunder Bay, Canada, was sequenced to 46-fold coverage using an Illumina MiSeq with 300-bp paired-end sequencing chemistry to produce 28 contigs with an N50 value of 490,721 bp.

SigD is translocated into eucaryotic cells by a type III secretion system. In this work, evidence that the putative chaperone SigE directly interacts with SigD is presented. A bacterial two-hybrid system demonstrated that SigE can interact with itself and SigD. In addition, SigD was specifically copurified with SigE-His(6) on a nickel column.

Here, we report draft genome sequences of 26 isolates of Salmonella enterica subsp. enterica, representing eight serotypes, which were isolated from cows in a Pennsylvania dairy herd, the farm on which they were reared, and the associated off-site heifer-raising facility over an 8-year sampling period.

The complete genome sequences of two isolates of Salmonella enterica serovars Anatum and Anatum var. 15+ revealed the presence of two plasmids of 112 kb and 3 kb in size in each. The chromosome of Salmonella Anatum (4.83 Mb) was slightly smaller than that of Salmonella Anatum var. 15+ (4.88 Mb).
