Abstract: In order to report the detection and main biological characteristics of pathogenic bacteria isolated from wild takin in the process of the natural survival, four strains of the predominant bacteria from pathologic tissues of dead takin's livers, spleens and lungs were examined and isolated.The detections of biochemical characteristics and 16S rDNA gene were conducted.The strains were isolated and identified as K.pneumoniae.The four isolates had pathogenicity to mice.LD50 of the four isolates were 2.9×107, 2.9×107, 4.5×107 and 1.1×108 CFU, respectively.The antibiotic sensitivity test revealed that the strains were sensitive to cephalothin and so on, moderate sensitive to amikacin and so on, and resistant to erythrocin and so on.The four strains of K.pneumoniae were the primary bacterial pathogen leading to the death of takin.

Key words: takin; K.pneumoniae; isolation and identification; LD50
