Abstract

This retrospective study incorporates a six years, six months (January 2000-June 2006) laboratory data comprising 258 isolates of Salmonella. Cultures were identified by standard methods. Salmonella enterica serotype Typhi (S.Typhi) was the more frequent serotype isolated i.e., 61.62% with the remaining 38.37% being Salmonella enterica serotype Paratyphi A (S. Paratyphi A). There was emergence of S. Paratyphi A as the predominant serotype in 2003-2004 with resurgence of serotype Typhi thereon. A total of 66.27% isolates were resistant to one or more antibiotics. MDR S. Typhi was 10.69% and while 13.13% were MDR S. Paratyphi A. There was decrease in resistance to ampicillin, cotrimoxazole in 2004 and nalidixic acid beyond 2005 and increase in resistance to cefuroxime. We also documented a decrease in resistance to ciprofloxacin after 2005.

摘要

这项回顾性研究纳入了2000年1月至2006年6月共六年零六个月的实验室数据,包括258株沙门氏菌分离株。采用标准方法对培养物进行鉴定。肠伤寒沙门氏菌(S.Typhi)是分离出的较常见血清型,即61.62%,其余38.37%为甲型副伤寒沙门氏菌(S.Paratyphi A)。甲型副伤寒沙门氏菌在2003 - 2004年成为主要血清型,随后伤寒血清型再次出现。共有66.27%的分离株对一种或多种抗生素耐药。多重耐药伤寒沙门氏菌为10.69%,而多重耐药甲型副伤寒沙门氏菌为13.13%。2004年对氨苄西林、复方新诺明的耐药性下降,2005年以后对萘啶酸的耐药性下降,对头孢呋辛的耐药性增加。我们还记录到2005年以后环丙沙星耐药性下降。
