Non-typhoidal salmonellosis presenting as acute calculus cholecystitis.

Non-typhoidal Salmonella spp.are Gram-negative bacilli, which typically cause a clinical picture of gastroenteritis and, less commonly, patients may become a chronic carrier of the pathogen within their gallbladder. We describe a rare clinical presentation of a non-typhoidal Salmonella spp. infection as acute calculus cholecystitis in an adult patient. Salmonella enterica subsp. Salamae (ST P4271) was grown from cholecystostomy fluid, and the patient subsequently underwent a laparoscopic cholecystectomy that demonstrated a necrotic gallbladder fundus. We advise that microbiological sampling of bile is essential, especially in the context of foreign travel, to detect unusual pathogens as in this case or common pathogens that may have unusual antimicrobial resistance. Given the necrotic gallbladder as in this case, we also advise that early cholecystectomy should be strongly considered in these patients. © BMJ Publishing Group Limited 2019. No commercial re-use.
