Transmission of Salmonella clones between different animal species in a horse and cattle breeding region in Japan

Nobuo ARAI, Hidekazu Niwa, Eri Uchida‐Fujii, Yuiko Sawa et autres

Sequence type 34 (ST34) Salmonella enterica serovar Typhimurium and its monophasic variant (Salmonella 4,[5],12:i:-) are the most prevalent clones among humans and animals worldwide, including in Japan. Although cross-species transmission may have occurred in the background of global spread, the matter remains …

Genetic basis of R-phase H:z27 antigen expression and phylogenetic relationships of Salmonella enterica serovar Senftenberg

Chieko Kato, Takahiro OCHIAI, Yuta Ohno, Ikuo Uchida et autres

Abstract Salmonella enterica serovar Senftenberg (S. Senftenberg) is one of the most common serovars isolated from various animals and humans. According to the White–Kauffmann–Le Minor scheme, its antigenic formula is defined as 1,3,19:g,[s],t:–, whereas 1,3,19:z27:– was formerly designated as serovar Simsbury but …

Characterization of α-hemolysin-specific monoclonal antibodies for detection in the culture supernatant of pathogenic Escherichia coli strains

Tomoko Kohda, Masafumi Mukamoto, Masahiro Kusumoto, Hideyuki Arimitsu

α-Hemolysin (α-Hly) is produced by pathogenic Escherichia coli and is implicated in a variety of diseases. In the swine, enterotoxigenic E. coli (ETEC) and Shiga toxin-producing E. coli (STEC) strains cause post-weaning diarrhea and edema disease, respectively, and most of these strains …

Association between farm-level antimicrobial usage and antimicrobial resistance in Escherichia coli isolates from healthy swine in ten farms in Japan

Yukino Tamamura-Andoh, Sota Kobayashi, Itsuro YAMANE, Mafumi Watanabe et autres

We examined the antimicrobial resistance of 1,493 Escherichia coli isolates from 440 swine fecal samples (211 and 229 samples were obtained from the sow and fattening groups, respectively) on ten farms and analyzed the association between the antimicrobial resistance rate and the …

Multiplex allele-specific PCR and DNA chromatography to identify genotypes of Salmonella enterica serovar Typhimurium and its monophasic variants

Nobuo Arai, Yukino Tamamura-Andoh, Taketoshi Iwata, Ayako Watanabe-Yanai et autres

We constructed a simple genotyping method combining multiplex allele-specific PCR and DNA chromatography for Salmonella enterica subsp. enterica serovar Typhimurium and its monophasic variant. The developed method can be used to estimate the genetic background of isolates, and it facilitates easy identification …
