Pre & Mains Notes
1. Salmonella Infections: Beyond Typhoid & Diarrhoea
WHAT HAPPENED
Experts highlight that Salmonella infections are broader than typhoid, with non-typhoidal Salmonella often causing undiagnosed gastroenteritis and sometimes severe bloodstream infections.
CORE ISSUE
India needs stronger surveillance and a One Health approach to address Salmonella transmission and rising antimicrobial resistance.
KEY DETAILS
Two major groups: S. Typhi and S. Paratyphi cause typhoid/paratyphoid, while non-typhoidal Salmonella (NTS) commonly causes gastroenteritis.
Transmission: NTS has a wider animal–environment–human cycle; poultry, eggs, meat and other animal-derived foods can act as sources.
AMR threat: Drug-resistant Salmonella is increasing; resistance to fluoroquinolones in S. Typhi reached 85% in 2015–19 in the cited study.
Way forward: Strengthen food safety, sanitation, surveillance and antimicrobial stewardship; use blood culture for suspected typhoid rather than relying solely on the Widal test.
WHY IT MATTERS
Salmonella demonstrates the One Health connection between humans, animals, food and the environment, while antimicrobial resistance threatens effective treatment.
