serotype Choleraesuis: a rare pathogen isolated from perianal abscess.

Infections with non-typhoidal salmonella (NTS) most commonly cause localised infections such as cutaneous abscesses in humans and are a leading source of foodborne illness. Here, we present a unique case of NTS Choleraesuis in a perianal abscess in an immunocompetent patient without any comorbidities.A woman in her late 40s was diagnosed with a perianal abscess with an unknown origin of infection. The patient has undergone an incision and drainage. Her pus culture and sensitivity report yielded serotype Choleraesuis. Then, the patient recovered after treatment with intravenous antibiotics and supportive treatment.We present an unusual case of serotype Choleraesuis, which is rarely reported as a causative agent of perianal abscess in India. This case has been reported for its rarity in India.
