Japanese encephalitis virus (JEV) is a zoonotic flavivirus that is transmitted by mosquitoes and vertebrate-amplifying hosts, including birds. Domestic ducks are susceptible to JEV infection and develop various levels of viremia. We tested the pathogenicities of seven JEV strains in newly hatched domestic ducklings. All inoculated ducklings showed stunted growth. Two JEV strains caused notable mortalities of 12.7% and 31.7%, respectively, highlighting that some emerged JEV strains may thus be pathogenic in newly hatched domestic ducklings.

Background: Enterotoxigenic Escherichia coli (E. coli) is one of the most prevalent causes of diarrhea in young animals. Postbiotics derived from yeast have the potential to positively influence the mucosal microbiota in the jejunum, therefore it was hypothesized that Saccharomyces yeast postbiotics could enhance the microbiota and mucosal immune response in the jejunum, mitigating the effects of infection with enterotoxigenic E.

Salmonellosis outbreaks are global issues primarily associated with the consumption of poultry products, which may be infected with Salmonella. The use of lytic bacteriophages could be a safe and effective approach to reduce Salmonella prevalence in poultry and subsequently the incidence in humans. This study examined the value of prophylactic phage treatment on Salmonella levels in chickens and the effect of such treatment on their overall gut microbiome.

Controlled source electromagnetics (CSEM) uses electromagnetic fields (EMF) to detect oil reservoirs. Atlantic haddock, Melanogrammus aeglefinus, is a commercially important demersal fish species that can potentially be impacted by such surveys due to potential overlap with egg distribution. In this study, haddock eggs were exposed to EMF, replicating CSEM survey conditions in a laboratory.

There are extensive differences in the caecal microbiota of chicks from hatcheries and those inoculated with faecal material from adult hens. Besides differences in microbial composition, the latter chickens are highly resistant to Enteritidis challenges, while the former are susceptible. In this study, we tested whether strains from genera , or can increase chicken resistance to and when defined microbial mixtures consisting of these bacterial genera are administered.
