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.
