Characterization of <i>Salmonella enterica</i> serovar Typhimurium and <i>Salmonella enterica</i> serovar 4,[5],12:i:- isolates from pigs presenting with diarrhea in Korea

다국어 초록 (Multilingual Abstract)

<P>Between 2011 and 2012, a total of 896 pig fecal samples were collected from nine provinces in Korea, and 50 <I>salmonella enterica </I>susp. <I>enterica</I> serovar Typhimurium (<I>S</I>. Typhimurium) was isolated. The characteristics of the 50 strains were analyzed, and 4 strains were identified as <I>Salmonella enterica</I> subsp. <I>enterica</I> serovar 4,[5],12:i:-. <I>Salmonella</I> 4,[5],12:i:- could not be distinguished from <I>S</I>. Typhimurium through phage typing, antimicrobial resistance testing or multiple-locus variable-number tandem repeat analysis (MLVA). However, among the four <I>Salmonella</I> 4,[5],12:i:- strains, one (KVCC-BA1400078) was identified as a <I>Salmonella</I> 4,[5],12:i:- clone isolated from humans in the United States, and another (KVCC-BA1400080) was identified as DT193, which has been primarily isolated from humans and animals in European countries. The presence of <I>Salmonella</I> 4,[5],12:i:- in Korea poses a significant threat of horizontal transfer between pigs and humans.</P>
