| Description | Due to significant stress, piglets after weaning are at an increased risk of developing gastrointestinal diseases, which can manifest as severe diarrhea, substantial morbidity, and mortality. To prevent these issues or mitigate them in the early stages, it is advisable to provide piglets with suitable probiotics. Lactic acid bacteria (LAB) sourced from the gastrointestinal tracts of wild pigs represent a promising yet underexplored source of probiotics for use in weaned piglets. In this study, 76 LAB strains from wild and domestic pigs were collected, sequenced, and identified. The presence of antibiotic resistance genes and hemolysin production was assessed to ensure the safety of these LAB strains for the host. LAB strains without resistance genes and hemolytic activity underwent further genotypic and phenotypic characterization to determine their beneficial probiotic properties. This included detecting genes for bacteriocins, adhesin-like factors, carbohydrate-active enzymes (CAZymes), and bile salt hydrolase. Additionally, in vitro tests were conducted to determine minimum inhibitory concentrations, antimicrobial activity against pathogens, and API tests for the utilization of carbohydrate substrates. |
