Summary: The present study showed that dietary supplementation of PHB did not affect the growth parameters of rainbow trout fingerlings, but significantly reduced total coliform counts and increased intestinal villus length and width. This suggests that PHB can be used as an alternative microbial control agent for improving intestinal health in rainbow trout.

Summary: This study develops a general theory for the time-dependent transient electrophoresis of a weakly charged spherical colloidal particle in a polymer gel medium. The Laplace transform of the transient electrophoretic mobility is derived by considering the hydrodynamic interaction between the particle and the gel medium based on the Brinkman-Debye-Bueche model. The theory covers both transient gel electrophoresis and transient free-solution electrophoresis, with the relaxation time for the former being shorter and decreasing as the Brinkman screening length decreases.

Summary: This study analyzed the composition of the intestinal microbiome in poultry and found that different samples at different stages had different microbial community compositions, but the compositions were not significantly correlated with the ability to colonize Salmonella. The study also found a correlation between the microbial compositions of commercial seeds and commercial products, but this correlation could not predict the efficacy of the products.

Summary: Microbial community assembly is a complex process that determines community structure and function. This study investigated how external nutrient supply rate influenced interactions and therefore community assembly. The presence of algae strongly influenced community assembly, leading to convergence of initially diverse bacterial consortia. This study highlights the importance of understanding assembly processes in complex phototroph-heterotroph communities for global ecosystem functioning.

Summary: This study examines the responses of bacterial populations in a coastal Holocene groundwater system to salinity and other environmental factors (EFs), finding that bacterial diversity is independent of salinity, while no significant increase or decrease in abundant bacterial relative abundance is observed with salinity changes. However, rare taxa exhibit growth with salinity, correlating significantly with sulfate concentration. The study suggests that the spatial organization of microbial communities is complex and influenced by multiple factors on a regional scale.

Summary: Understanding how soil microbial communities respond to temperature changes is crucial for understanding their distribution and abundance. By studying a unique area in Iceland with a stable warming gradient, researchers found that soil bacterial communities in grassland and forest adapted similarly to warming, with significant changes occurring at soil temperatures 6-9 degrees Celsius above ambient.

Summary: On November 5, 2020, an outbreak of H5N8 highly pathogenic avian influenza virus occurred at an egg-hen farm in Kagawa prefecture, Japan, resulting in 100% mortality of chickens. Phylogenetic analysis revealed that the virus is closely related to H5N8 HPAIVs isolated from wild bird feces collected in Hokkaido (Japan) and Korea, as well as to those isolated in European countries during the winter of 2019-2020.

Summary: Virulent fowl adenovirus serotype 4 (FAdV-4) causes hydropericardium syndrome (HPS) in chickens, resulting in high mortality and economic losses. In this study, a recombinant fiber-1 protein of FAdV-4 was produced and its immunogenicity and protective efficacy were evaluated. The protein induced high levels of neutralizing antibodies in immunized chickens, providing protection against clinical signs of infection and viral load reduction.

Summary: The study found that Japanese native chickens exhibit varying susceptibility to different strains of H5 highly pathogenic avian influenza viruses, with two breeds showing some degree of resistance to certain viruses while being more sensitive to others compared to commercial broiler chickens. This suggests that the pathogenic characteristics of HPAIVs differ significantly between native and commercial chickens.

Summary: In recent years, there has been an increase in the occurrence of fowl adenovirus 2 (FAdV-2) in China, posing a significant threat to the poultry industry. This study investigated the epidemiology, phylogenetic relationship, genomic characteristics, and pathogenicity of FAdV-2. The results showed that FAdV-2 was the most commonly detected serotype among various FAdV serotypes. Genetic analysis revealed that these FAdV-2 strains formed a distinct branch within the FAdV-D group and had a high nucleotide similarity with reference strains. Recombination analysis identified recombination events between FAdV-2 and FAdV-11 in some strains. Pathogenicity experiments demonstrated that a recombinant FAdV-2 strain caused a high mortality rate and more severe disease in chickens. These findings contribute to our understanding of FAdV-2 and provide a basis for vaccine development.

The results showed that perceived severity and perceived benefits positively influenced vendors' self-efficacy in the wholesale market, while perceived barriers negatively affected self-efficacy in both the wholesale and retail markets. Moreover, cues to action mediated the relationship between perceived severity, perceived benefits, and self-efficacy, and also mediated the effect of perceived susceptibility among wholesale market vendors.
