Abstract
This study aimed to use lactic acid bacteria isolated from piglet faeces todevelop probiotics, allowing for the effective control ofEscherichia coli and Salmonella. Lactic acid bacteria were isolated from the faeces ofsuckling piglets and identified by16SrRNA sequencing, then examined for haemolysis; gelatinase activity; and resistance toacid, bile, and pancreatin. The antimicrobial activity ofselected lactic acid bacteria isolates was examined for 8E.coli and 7Salmonella strains. One-hundred and sixty-four lactic acid bacteria isolates were identified from 118piglet faecal samples, and 13lactic acid bacteria isolates were selected from analyses ofhaemolysis; gelatinase activity; and resistance toacid, bile, and pancreatin. Ofthe selected 13lactic acid bacteria isolates, Limosilactobacillus reuteri PF20-3 and PF30-3 strains had the highest antibacterial activity against E.coli and Salmonella.
