Abstract:

The experiment was aimed to identify the bacterial distribution and drug resistance situation in deer farm environment form Xifeng county, Liaoning province. We collected manure, water, air and feed samples from deer farm for isolation and identification of bacteria, bacterial count, bacterial 16S rDNA PCR amplification, sequencing analysis, and the pathogenic bacteria and conditional pathogenic bacteria of drug sensitivity test. The results showed that there were 27 strains of bacteria isolated and purified, enumeration of male and female deer's pellet feed, fodder and water were 1.0×105,8.7×104,2.7×107 CFU/g and 2.9×104 CFU/mL, respectively. Description of water and fodder did not conform to the standard of the national health requirements; 16S rDNA gene sequences comparison in NCBI showed that these bacteria belonged to 15 kinds of different kinds, like Escherichia coli, Shigella sp., and so on. There were 13 kinds of pathogenic bacteria and conditional pathogenic bacteria. The 13 kinds were resistant to furazolidone, polymyxin B and cephalexin, and were sensitive to ceftriaxone, ciprofloxacin and amikacin. These results provided basis for efficient control of the disease in deer farm.
