To determine the prevalence of the virulence plasmid in Salmonella Typhimurium isolates from pigs in Japan, a total of 106 porcine isolates were subjected to PCR amplification for the detection of the virulence plasmid. Out of the isolates of S. Typhimurium, 38 (35.8%) harbored the virulence plasmid. The presence of the virulence plasmid was widely observed in the isolates from systemically infected pigs (92.0%, 23/25), compared with diarrheic (18.8%, 12/64) and apparently healthy pigs (17.6%, 3/17) (P<0.01).
为了确定日本猪源鼠伤寒沙门氏菌分离株中毒力质粒的流行情况，共对106株猪源分离株进行了PCR扩增，以检测毒力质粒。在鼠伤寒沙门氏菌分离株中，38株（35.8%）携带毒力质粒。与腹泻猪（18.8%，12/64）和健康猪（17.6%，3/17）相比，在全身感染猪的分离株中广泛观察到毒力质粒的存在（92.0%，23/25）（P<0.01）。
