11株益生菌对32种抗菌药物的敏感性试验

The sensitivity test of eleven helpful living bacteria strains about 32 kinds antibacterial

以6株猪源乳杆菌、1株植物乳杆菌和4株芽孢杆菌对32种抗菌药物进行了敏感性试验。结果表明:猪源乳杆菌对32种抗菌药物的耐受性达53.1%￣71.9%,而植物乳杆菌对12种药物有耐受性;4株芽孢杆菌几乎对所有参试的抗菌药物(杆菌肽除外)均具有敏感性。试验结果对微生物饲料添加剂的研制及其在畜禽生产中的应用具有指导意义。

6 strains porcine lactobacillus, 1 strain plant lactobacillus and 4 strains sporangium bacilliform bacteria were detected the sensitivity to 32 kinds antibacterial in this test. The results showed that 6 strains porcine lactobacillus had the resistant to 53.1%-71.9% antibacterial of 32 kinds antibacterial; 1 strain plant lactobacillus had the resistant to 12 of the 32 kinds antibacterial; and 4 strains sporangium bacilliform bacteria were sensitive to 32 kinds antibacterial except Bacitracin. This test results have scientific guidance meaning for developing and application in livestock and poultry production of microbe animal feed additive.
