Characteristics of Salmonella enterica Serovar 4,[5],12:i:- as a Monophasic Variant of Serovar Typhimurium
Salmonella enterica subspecies enterica serovar 4,[5],12:i:- (S. 4,[5]12:i:-) is believed to be a monophasic variant of S. enterica serovar Typhimurium (S. Typhimurium). This study was conducted to corroborate this hypothesis and to identify the molecular and phenotypic characteristics of the S. 4,[5]12:i:- isolates in Japan. A total of 51 S. 4,[5]12:i:- isolates derived from humans, cattle, sw...

Introduction: In Iran, invasive nontyphoidal Salmonella (iNTS) disease causes severe bacteremic illness among children <5 years old. The global yearly incidence of iNTS disease in children was reported to be in the 3.4 (range 2.1-6.5) million cases, (overall incidence 49 cases (range 30-94) per 100,000 population), the iNTS case-fatality ratio (CFR) of 20% yielded 681,316 deat...
متن کاملMolecular Characterization of a Salmonella Typhimurium Isolate from Caspian Pony
Typhoid disease or salmonellosis is a common sickness in horses. In several epidemiological studies inhospitalized horses, several serotypes of Salmonella often are predominant in nosocomial infections.Transportation, overcrowding, dehydration, oral antimicrobial therapy and infections are the risk factorswhich may activate latent or subclinical salmonellosis. In this study, t...
متن کاملGenomic subtraction identifies Salmonella typhimurium prophages, F-related plasmid sequences, and a novel fimbrial operon, stf, which are absent in Salmonella typhi.
Salmonella typhimurium causes systemic and fatal infection in inbred mice, while the related serotype Salmonella typhi is avirulent for mammals other than humans. In order to identify genes from the virulent strain S. typhimurium ATCC 14028 that are absent in S. typhi Ty2, and therefore might be involved in S. typhimurium mouse virulence, a PCR-supported genomic subtractive hybridization proced...
متن کاملDiversity of Plasmids Encoding Virulence and Resistance Functions in Salmonella enterica subsp. enterica Serovar Typhimurium Monophasic Variant 4,[5],12:i:- Strains Circulating in Europe
Plasmids encoding resistance and virulence properties in multidrug resistant (MDR) Salmonella enterica (S.) serovar Typhimurium monophasic variant 4,[5],12:i:- isolates recovered from pigs and humans (2006-2008) in Europe were characterised. The isolates were selected based on the detection by PCR-amplification of S. Typhimurium virulence plasmid pSLT genes and were analysed by multi-locus sequ...
