Salmonella enterica subsp. enterica serovar Heidelberg is a highly clonal serovar frequently associated with foodborne illness. To facilitate subtyping efforts, we report fully assembled genome sequences of 17 Canadian S Heidelberg isolates including six pairs of epidemiologically related strains. The plasmid sequences of eight isolates contain several drug resistance genes. © Crown copyright 2016.
Carbapenem-resistant Enterobacteriaceae (CRE) are a pressing public health issue due to limited therapeutic options to treat such infections. CREs have been predominantly isolated from humans and environmental samples and they are rarely reported among companion animals. In this study we report on the isolation and plasmid characterization of carbapenemase (IMP-4) producing Salmonella enterica Typhimurium from a companion animal. Carbapenemase-producing S. enterica Typhimurium carrying blaIMP-4 was identified from a systemically unwell (index) cat and three additional cats at an animal shelter. All isolates were identical and belonged to ST19. Genome sequencing revealed the acquisition of a multidrug-resistant IncHI2 plasmid (pIMP4-SEM1) that…
Foodborne infections caused by Salmonella enterica serovars are a significant problem worldwide. Presented here is the genome sequence of the nontyphoidal S. enterica serovar Typhimurium mutant strain NC983, a potential vaccine candidate. Copyright © 2016 Troxell et al.
This study reported and analysed the complete sequences of two oqxAB-bearing IncHI2 plasmids harboured by a clinical S. Typhimurium strain and an S. Indiana strain of animal origin, respectively. Particularly, pA3T recovered from S. Indiana comprised the resistance determinants oqxAB, aac(6′)Ib-cr, fosA3 and blaCTX-M-14 Further genetic screening of 63 oqxAB-positive Salmonella spp. isolates revealed that the majority carried IncHI2 plasmids, confirming that such plasmids play a pivotal role in dissemination of oqxAB in Salmonella spp..

Salmonella enterica is a leading cause of enterocolitis for humans and animals. S. enterica subsp. enterica serovar Typhimurium infects a broad range of hosts. To facilitate genomic comparisons among isolates from different sources, we present the complete genome sequences of 10 S Typhimurium strains, 5 each isolated from human and bovine sources.

Salmonellae are a significant cause of morbidity and mortality globally. Here, we report the first complete genome sequence for Salmonella enterica subsp. enterica serovar Java strain NCTC5706. This strain is of historical significance, having been isolated in the pre-antibiotic era and was deposited into the National Collection of Type Cultures in 1939.© Crown copyright 2016.
