This study aimed to use lactic acid bacteria isolated from piglet faeces to develop probiotics, allowing for the effective control of and . 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 and 7 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, PF20-3 and PF30-3 strains had the highest antibacterial activity against and .
本研究旨在利用从仔猪粪便中分离出的乳酸菌开发益生菌，以有效控制和。从哺乳仔猪粪便中分离出乳酸菌，并通过16S rRNA测序进行鉴定，然后检测其溶血情况、明胶酶活性以及对酸、胆汁和胰酶的抗性。对选定的乳酸菌分离株进行抗菌活性检测，检测了8株和7株。从118份仔猪粪便样本中鉴定出164株乳酸菌分离株，并通过对溶血情况、明胶酶活性以及对酸、胆汁和胰酶的抗性分析，选出13株乳酸菌分离株。在选定的13株乳酸菌分离株中，PF20 - 3和PF30 - 3菌株对和具有最高的抗菌活性。
