Unilateral Breast Abscess by an Extremely Drug Resistant Salmonella enterica serovar Typhi: First Case Report from Pakistan

Abstract

Invasive salmonellosis caused by Salmonella typhi and Salmonella paratyphi is a serious life-threatening complication in immunocompromised patients. Since blood cultures have only 40-80% sensitivity, very limited diagnostic modalities are left. Here, authors present a case of a 24-year-old pregnant lady who develops a unilateral breast abscess harbouring Salmonella typhi. The isolate was Extremely Drug Resistant (XDR), that is resistant to first line drugs, ciprofloxacin and ceftriaxone. She was successfully treated with combination of injection meropenem and tablet azithromycin and continued for 14 days. To the best of authors knowledge, this was the first reported case of Salmonella enterica serovar Typhi in a pregnant lady from Pakistan.
