| Abstract: | Between 2011 and 2012, a total of 896 pig fecal samples were collected from nine
provinces in Korea, and 50 salmonella enterica susp.
enterica serovar Typhimurium (S. Typhimurium) was
isolated. The characteristics of the 50 strains were analyzed, and 4 strains were
identified as Salmonella enterica subsp. enterica
serovar 4,5],12:i:-. Salmonella 4,5],12:i:- could not be distinguished
from S. Typhimurium through phage typing, antimicrobial resistance
testing or multiple-locus variable-number tandem repeat analysis (MLVA). However, among
the four Salmonella 4,5],12:i:- strains, one (KVCC-BA1400078) was
identified as a Salmonella 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
Salmonella 4,5],12:i:- in Korea poses a significant threat of
horizontal transfer between pigs and humans. |
