Six month follow-up study on Salmonella typhi and Salmonella paratyphi. A infections for carrier state

ABSTRACT

Humans are the only natural reservoir of Salmonella typhi and Salmonella paratyphi A., therefore, the disease can be acquired through proximity with a person who is a chronic carrier. Most often this involves acquisition of organisms via ingestion of food or water contaminated with human excreta. A follow up study was carried out at the Armed Forces institute of Pathology [AFIP] Rawalpindi on 22 patients at two monthly intervals over a period of six months, with the objective to detect Salmonella typhi and Salmonella paratyphi A carrier state among these patients. Follow up investigations included stool cultures for both salmonella infections. None of our cases terminated as chronic carrier for Salmonella typhi and S. paratyphi A
