This study reports a botulism outbreak on a pig farm. Clostridium botulinum type C was detected using PCR. The gene encoding the toxin corresponds to a novel type C neurotoxin recently described in a human botulism outbreak, raising the question of its prevalence in pigs and the related risks to humans.

Interest in the conversion of manure in biogas via anaerobic digestion (AD) is growing, but questions remain about the biosafety of digestates. For a period of one year, we monitored the impact of three mesophilic agricultural biogas plants (BPs) mainly fed with pig manure (BP1, BP3) or bovine manure (BP2) on the physicochemical parameters, the composition of the microbial community and the concentration of bacteria (E. coli, enterococci, Salmonella, Campylobacter, Listeria monocytogenes, Clostridium perfringens, Clostridium botulinum and Clostridioides difficile).

Article Synopsis
  • * This study analyzes immune responses in broiler chickens to identify key immune factors that could lead to better vaccine development against Campylobacter, building on previous studies with Leghorn chickens.
  • * The findings show that while vaccinated broilers didn't reduce Campylobacter colonization, they exhibited a systemic immune response with specific antibody production and increased expression of certain immune genes, despite low levels of mucosal antibody production.

Article Synopsis
  • The text discusses the challenges of combating a leading zoonotic disease in Europe, primarily found in poultry, as there is currently no effective vaccine available for this infection in chickens.
  • A study focused on the immune responses and gut microbiota changes in chickens after vaccination with a DNA/protein flagellin-based vaccine, which previously showed promise in providing some protection.
  • The results indicated that while vaccinated chickens had reduced bacterial loads and produced specific antibodies, their gut microbiota composition also changed significantly, suggesting vaccination may influence both immune response and gut health.
