Hybrid strains of enterotoxigenic/Shiga toxin-producing , United Kingdom, 2014-2023.

Diarrhoeagenic (DEC) pathotypes are defined by genes located on mobile genetic elements, and more than one definitive pathogenicity gene may be present in the same strain. In August 2022, UK Health Security Agency (UKHSA) surveillance systems detected an outbreak of hybrid Shiga toxin-producing /enterotoxigenic (STEC-ETEC) serotype O101:H33 harbouring both Shiga toxin () and heat-stable toxin (). These hybrid strains of DEC are a public health concern, as they are often associated with enhanced pathogenicity.

Background: Enterotoxigenic F4 E. coli (F4-ETEC) pose an economic threat to the swine industry through reduced growth, increased mortality and morbidity, and increased costs associated with treatment. Prevention and treatment of F4-ETEC often relies on antimicrobials; however, due to the threat of antimicrobial resistance, antimicrobial use is being minimized, and hence alternative control methods are needed.

Background: The emergence of antibiotic resistant microorganisms associated with conventional swine production practices has increased interest in acid-based compounds having antimicrobial properties and other biological functions as nutritional interventions. Despite the interest in organic acids and monoglycerides, few studies have examined the effects of the combination of these acid-based additives in weaned pigs under disease challenge conditions. Therefore, this study aimed to investigate the effects of dietary supplementation with blend of organic acids and/or medium-chain fatty acid monoglycerides on intestinal health and systemic immunity of weaned pigs experimentally infected with an enterotoxigenic Escherichia coli (ETEC) F18 at 4-week of age.

Enteropathogens are major contributors to mortality and morbidity, particularly in settings with limited access to water, sanitation, and hygiene infrastructure. To assess transmission pathways associated with enteropathogen infection, we measured household environmental conditions and assayed 22 enteropathogens using TaqMan Array Cards in stool samples from 276 six-month-old children living in communities along a rural-urban gradient in Northern Ecuador. We utilized multivariable models, risk factor importance, and distance-based statistical methods to test factors associated with infection.

Milk is commonly screened both for indicators of animal disease and health, but also for foodborne hazards. Included in these analyses is the detection of , that can produce an enterotoxin, causing staphylococcal food poisoning (SFP), which often leads to sudden onset of significant gastrointestinal symptoms in humans. Epidemiological data on SFP are limited, particularly in low- and middle-income countries.
