几种鸡源肠道菌对沙门氏菌的体外生物拮抗试验

Biological Antagonistic Assay of Some Chicken Intestinal Bacteria against Salmonella in vitro

用从健康鸡消化道分离的鸡源乳酸杆菌 4株 ,双歧杆菌 2株 ,芽孢杆菌 2株 ,对引起雏鸡腹泻的鸡白痢沙门氏菌和鸡副伤寒沙门氏菌进行体外生物拮抗试验。试验结果显示 :3株乳酸杆菌、2株双歧杆菌、1株芽孢杆菌对致病性沙门氏菌均有明显的生物拮抗作用 (P <0 .0 1) ,而 1株乳酸杆菌和

The biological antagonstic assay of 4 stains of Lactobacillus 2 strains of Bifidobacteria and 2 strains of Bacillus isolated from healthy chickens against chicken Salmonella pullorum and Salmonella paratyphi causing chicken diarrhea was Conducted in vitro.The results showed 3 strains of Lactobacillus,2 strains of Bifidobacteria and 1 stain of Bacillus had remarkably antagonstic effect on Salmonella (P<0.01),but 1 stain of Lactobacillus and Bacillus had no one on them.
