Antimicrobial prescribing practices for enteric bacterial infections in an integrated health care system, Wisconsin, 2004-2017.
J Infect Public Health
January 2025
Marshfield Clinic Research Institute, Marshfield, WI, United States. Electronic address:
Background: Few studies have evaluated antibiotic prescribing practices for bacterial enteric infections. Unnecessary antibiotics can result in adverse events and contribute to the emergence of antimicrobial resistance. We assessed treatment practices among patients with laboratory-confirmed enteric infections in a regional healthcare system in Wisconsin, USA.

Article Synopsis
- Cockroaches show varying levels of susceptibility to Typhimurium infection, and their gut microbiota plays a key protective role against this colonization.
- Research indicates that the presence of commensal bacteria in the gut does not directly compete with Typhimurium but helps activate the cockroach's defenses by boosting antimicrobial peptide production.
- The study reveals that specific minority bacterial species, rather than the overall number or diversity of gut bacteria, are important for understanding infection susceptibility, highlighting cockroaches as a potential model for studying microbial interactions and reducing disease spread.
Serovars, virulence factors, and antimicrobial resistance profile of non-typhoidal Salmonella in the human-dairy interface in Northwest Ethiopia: A one health approach.

Article Synopsis
- * In a study conducted in Northwest Ethiopia from June 2022 to August 2023 across 58 dairy farms, 362 samples were tested for NTS, resulting in detection of 28 isolates (7.7%), with S. Uganda being the most prevalent serovar.
- * The study found that 100% of NTS isolates had the invA virulence gene, 21.4% had spvC, and a high proportion (89.3%) were resistant to at least
Peritonitis-related bacterial infections: a large-scale case-series retrospective study in 160 domestic animals (2009-2022).

Bacterial peritonitis infections comprise a life-threatening clinical condition in domestic animals that commonly lead to sepsis and high mortality. A set of bacterial pathogens have been identified in septic peritonitis in livestock and companion animals. Nonetheless, most descriptions are restricted to case reports or limited to only one domestic species, and a restrict number of comprehensive studies involving this infection has focused on a great number of domestic animals.

Introduction: Non-typhoidal (NTS) is a major cause of gastroenteritis worldwide, often associated with meat consumption and meat processing. Research on NTS infection and circulating serovars in meat value chains in Uganda is limited. We aimed to establish NTS prevalence, antimicrobial resistance, and risk factors among slaughterhouse workers, and to identify potentially zoonotic serovars in the pork value chain.
