Salmonella Newport Gastroenteritis in an Adult- A Rare Case Report

Abstract

Salmonella Newport is a major cause of food-borne infection which occurs due to consumption of contaminated food items. Stool sample from a suspected case of enteric fever was received in the Central Microbiology Laboratory of a tertiary care teaching hospital in Southern India. The bacterial isolate was identified on the basis of Gram Staining, cultural characteristics and biochemical reactions as Salmonella species. Agglutination for serotyping was done and it was found to be agglutinable by only Polyvalent O antiserum. For further speciation, the isolate was sent to the National Institute of Cholera and Enteric Diseases (NICED), Kolkata, West Bengal, India and was identified as Salmonella enterica serotype Newport. The patient responded well to ciprofloxacin therapy. As the diagnosis of Non-Typhoidal Salmonellosis (NTS) is often challenging, patients with suspected Salmonella infections are usually given empirical antibiotic therapy which can cause an increase in drug resistant NTS.
