Isolation-dentification And Drug Sensitivity Study On The Bacteria Of The Canine Otitis Media In Nanchang

Canine otitis media in our working dogs for police use is a frequently-occurring disease, according to case statistics from Dog Disease Research Center of Ministry of Public Security, the average annual incidence rate of dog disease is 3.86%. and the climate of Nanchang area is warm and humid, which is especially suitable for breeding of bacteria, so the disease incidence rate is higher in the this area, reaching 6.54%. If the disease can not be effectively treated in time, will seriously affect the hearing of dogs and directly result in the decline in the performance of their work, or even lost the hearing. In different regions, the distribution of the disease spectrum of pathogens and drug sensitivity is also different, which is very difficult to choose the suitiable drugs on the clinical use. The purpose of this study is to analyze the spectral distribution of the bacteria on canine otitis media in Nanchang area and the susceptibility of various pathogenic strains for providing a scientific reference on drug selection. Methods:to cultivate, isolate and identify the 124 cases of middle ear secretion of the dogs suffering otitis media, and make susceptibility testing on the pathogenic bacterium isolated. Results:152 pathogen was isolated s from 6 kinds, respectively,60 strains of Staphylococcus aureus accounted for 39.5%,40 strains of Streptococcus pneumoniae 26.3%, intermediate Staphylococcus aureus accounted for 16.4% of 25 strains,10 strains of Pseudomonas aeruginosa accounted for 6.6%,8 strains of E. coli and 9 strains of Candida albicans accounted for 5.2% and 5.9%. Drug susceptibility test results are mainly Staphylococcus aureus G + bacteria to fluoroquinolones, chloramphenicol class, vancomycin, lincomycin, sensitive to ceftazidime and other antibiotics:Pseudomonas aeruginosa-based G - bacteria to fluoroquinolones. chloramphenicol class, aminoglycosides. ceftazidime and other antibiotics sensitive. Conclusion:The clinical treatment of the disease should be based on the results of bacterial culture and sensitivity test to select drug treatment, and considering the fungi and/or mixed infections and drug's side effects.
