Alerts in Pakistan
Extensively drug-resistant (XDR) Salmonella was first reported in Sindh, Pakistan, in 2016. Since then, several districts have reported cases caused by multiple XDR S. enterica serovar typhi variants belonging to clade H58 and carrying multiple novel genomic integrations of the extended-spectrum beta-lactamase gene. Most cases are managed with meropenem and azithromycin, and most national guidelines recommend those drugs for treating cases of Salmonella typhi in Pakistan. We report a case of carbapenem-resistant Salmonella typhi infection that required treatment with a last-resort antimicrobial drug.
