Non-typhoidal salmonellosis is a foodborne disease caused by spp. Most outbreaks of this disease are commonly associated with consuming contaminated meat products, hence the importance of monitoring ready-to-eat artisanal pork sausages for the presence of these bacteria. A total of 494 samples of grilled and smoked barbecue artisanal pork sausages were collected at food outlets from 12 municipalities of the Department of Quindío, Colombia, between 2017 and 2022.

Paratyphoid B fever (PTB) is caused by an invasive lineage (phylogroup 1, PG1) of Salmonella enterica serotype Paratyphi B (SPB). However, little was known about the global population structure, geographic distribution, and evolution of this pathogen. Here, we report a whole-genome analysis of 568 historical and contemporary SPB PG1 isolates, obtained globally, between 1898 and 2021.

Enteric fever is caused by the infection of Gram-negative bacteria, Salmonella enterica serovar Typhi and Salmonella enterica serovar Paratyphi (S. Paratyphi) A, B and C, through contaminated food and water. The disease almost exclusively affects the populations living in low- and middle-income countries, with the World Health Organization Southeast Asian Region (WHO SEAR) having the highest endemicity.

Article Synopsis
  • The study investigated trends and spatial patterns of typhoid and paratyphoid fever (TPF) in Yunnan Province to inform better prevention strategies.
  • From 1989 to 2022, there were over 206,000 TPF cases, peaking in July and August, with the highest incidence in the 25-34 age group and among farmers.
  • Results indicated a significant decrease in TPF incidence, with specific high-incidence areas identified, suggesting that prevention efforts should target these hotspots and seasons.
