The stool samples from 245 patients with diarrhea were tested for heat labile toxin (LT) and heat stable toxins (ST) by passive latex agglutination and enzyme immunoassay methods respectively. Twelve (4.9%) enterotoxigenic E. Coli ETEC strains were isolated. Five strains (2%) expressed ST, and 7 (2.8%) expressed LT.

This study aims to validate sanitation standard operating procedures (SSOP) of the pre-cooling system in two immersion stages with different temperatures followed by dripping for 3 minutes. The variables evaluated were temperature, weight, microbiological quality, and safety of chicken carcasses. Groups of indicator microorganisms were quantified and the occurrence of Salmonella spp.

Enterotoxigenic (ETEC) is a major pathogen causing diarrhea in humans and animals, with increasing antimicrobial resistance posing a growing challenge in recent years. Lytic bacteriophages (phages) offer a targeted and environmentally sustainable approach to combating bacterial infections, particularly in eliminating drug-resistant strains. In this study, ETEC strains were utilized as indicators, and a stable, high-efficiency phage, designated vB_EcoM_JE01 (JE01), was isolated from pig farm manure.

Background: Globally, diarrhoeagenic Escherichia coli (DEC) has been implicated in the spread of waterborne diseases and abattoir wastewater has played a role in its dissemination into watersheds. This study isolated and characterised DEC from the abattoir wastewater-impacted Iyi-Etu River and other water sources at the Amansea livestock market settlement.
Methods: A total of 96 water samples comprising river water (upstream, downstream 1, downstream 2), borehole, well, sachet and abattoir wastewater samples were tested for DEC.
