貂源铜绿假单孢菌的分离鉴定及其致病性研究
Isolation and identification of Pseudomonas aeruginosa from minks and study on pathogenicity of P. aeruginosa
摘要
Abstract
A Pseudomonas aeruginosa strain was isolated from the lung of a dead mink from Weihai of Shandong Province. We identified the P. aeruginosa based on colony characteristics, biochemical tests and PCR. Pathogenicity test showed that the LD50 for mice was 1.4× 107 CFU/mL,and the MLD was 8.0× 106 CFU/mL. we successfully isolated the same bacteria as infectious bacteria. Drug susceptibility test showed that the isolated strain was sensitive to drugs including gentamicin, ciproflaxin, norfloxacin, and cefoperazone,but resisted to penicillin and streptomycin. Phylogenetic analysis showed that the isolate was closely related to members of P. aeruginosa from the wheat, therefore we inferred the bacteria originally coming from contaminated feed.关键词
