Abstract
This study aimed to use lactic acid bacteria isolated from piglet faeces to develop probiotics, allowing for the effective control of Escherichia coli and Salmonella. Lactic acid bacteria were isolated from the faeces of suckling piglets and identified by 16S rRNA sequencing, then examined for haemolysis; gelatinase activity; and resistance to acid, bile, and pancreatin. The antimicrobial activity of selected lactic acid bacteria isolates was examined for 8 E. coli and 7 Salmonella strains. One-hundred and sixty-four lactic acid bacteria isolates were identified from 118 piglet faecal samples, and 13 lactic acid bacteria isolates were selected from analyses of haemolysis; gelatinase activity; and resistance to acid, bile, and pancreatin. Of the selected 13 lactic acid bacteria isolates, Limosilactobacillus reuteri PF20-3 and PF30-3 strains had the highest antibacterial activity against E. coli and Salmonella.
