对 1989 年至 1998 年间获得的 11 份婴儿沙门氏菌肉鸡分离株进行了抗菌敏感性和脉冲场凝胶电泳 (PFGE) 分析。 1993 年之后分离的 7 株婴儿沙门氏菌菌株与 2001 至 2003 年间最近分离的菌株具有相似的抗菌敏感性。将 PFGE 谱与 2001 至 2003 年间从 22 只明显健康的肉鸡中获得的 22 株菌株进行比较，主要集群包括 1993 年之后分离的 7 株。我们无法澄清该血清型流行的原因长期以来，抗生素的使用并不总是与其流行相关。
Eleven broiler isolates of Salmonella Infantis obtained between 1989 and 1998 were examined for antimicrobial susceptibility and pulse field gel electrophoresis (PFGE) profiles. Seven strains of S. Infantis isolated after 1993 harbored similar antimicrobial susceptibilities to the recent isolates between 2001 and 2003. In comparison of PFGE profile with 22 isolates obtained from 22 apparently healthy broiler chickens between 2001 and 2003, the predominant cluster included the seven strains isolated after 1993. We could not clarify the reasons why the serovar has been prevalent in the broiler industry for a long time, but current antimicrobial usage is not always linked to its prevalence.
