Summary: The pathogenicity of B. pumilus strains isolated from cows with and without endometritis was evaluated in this study using a cell-culture-based approach. These strains were found to possess specific genes related to enzyme production and caused damage to endometrial bovine cells in a dose-dependent manner. These findings have important implications for understanding the role of this pathogen in the disease.

Summary: In this study, a bacterial strain identified as Bacillus amyloliquefaciens with probiotic potential was isolated from the digestive tract of rohu fish. The strain showed strong antimicrobial activity, tolerance to a wide range of pH and bile salt concentration, and high adhesion properties, with the presence of putative probiotic marker genes. The findings suggest the potential use of this strain in the aquaculture industry.

Summary: In this study, traditional fermented foods and soil samples were collected from various provinces in China, leading to the selection of 9 Bacillus strains that passed resistance tests for acid, alkali, bile salt, and trypsin. Out of these, 3 strains showed antibiotic sensitivity to more than 29 antibiotics. Gene analysis confirmed that these 3 strains belong to Lysinibacillus capsici and Bacillus halotolerans. Animal experiments confirmed their safety, and L. capsici 38,327 and 38,328 exhibited protective effects in a Salmonella typhimurium infection mouse model. These findings suggest that selected L. capsici strains can be used as novel probiotics for intestinal health.

Summary: In this study, two potential probiotics were isolated from the intestinal tract of Rhynchocypris lagowskii and their probiotic potential was assessed. The strains demonstrated excellent tolerance to various stress conditions and exhibited inhibitory effects against common bacterial pathogens. These findings suggest that these probiotics can be used for the healthy breeding and disease prevention of R. lagowskii.

Summary: The aim of this study was to isolate Bacillus species with good probiotic properties from yak feces. Various tests were conducted on the isolated Bacillus, which included identification, antibacterial activity, tolerance, hydrophobicity, auto-aggregation, sensitivity, growth performance, antioxidants, and immune indexes. A safe and harmless Bacillus pumilus strain with high survival rate, hydrophobicity, auto-aggregation, and antibacterial activity was identified. Feeding mice with this strain promoted weight gain, improved gut health, and enhanced immune response. This study confirms the probiotic effects of Bacillus pumilus isolated from yak feces and provides a theoretical basis for clinical application and development of new feed additives.

Summary: In this study, two bacterial strains with antagonist activity against Vibrio parahaemolyticus were isolated from saline sediment in Mexico. The draft genome sequences of these strains were determined, and the analysis revealed the presence of biosynthetic gene clusters responsible for antimicrobial metabolite production. The findings suggest the potential of these strains as probiotics in shrimp aquaculture.
