Genomic Surveillance of <i>Salmonella</i> London and Rissen Reveals International Transmission Patterns and Expanding Antimicrobial Resistance - Shanghai Municipality, China, 2020-2024.

ABSTRACT:

What is already known about this topic?

Non-typhoidal Salmonella (NTS) represents a leading cause of foodborne gastroenteritis worldwide. The epidemiological landscape of NTS continues to evolve, with specific serotypes emerging as significant human pathogens through contaminated food products. This evolution occurs particularly within the context of globalized food supply chains and widespread antimicrobial use in agricultural settings.

What is added by this report?

This study integrated local isolates from Shanghai with global genomic data to reveal distinct international transmission patterns for Salmonella London and Rissen. S. London disseminated through historical, geographically segregated clades, whereas S. Rissen demonstrated recent inter
