中朝边境鸭绿江江水细菌分布及耐药性监测

7.解放军65755部队卫生队,辽宁宽甸118200)摘要:目的了解军营附近鸭绿江水域的细菌种类、分布情况及细菌对抗菌药物的敏感性。防止部队因环境污染造成战士非战斗减员。方法采用采样器采集鸭绿江江水15个不同水域,每个位置采集3份,45份水样经增菌培养和细菌分离,采用全自动微生物分析仪进行细菌学鉴定及抗菌药物敏感性试验。结果共分离出细菌45种218株,其中肠杆菌科细菌88株(44.89%)、非发酵菌52株(26.53%)、弧菌科细菌50株(25.51%)、革兰阳性球菌22株(10.09%)。药敏试验结果显示,88株肠杆菌科细菌对亚胺培南、美罗培南、哌拉西林/他唑巴坦、头孢哌酮/舒巴坦、头孢吡肟、阿米卡星的敏感率为100%,对三代头孢菌素、喹喏酮类、氨曲南敏感率为85.95%,非发酵菌敏感率均为95%～100%,弧菌科细菌敏感率为95%～100%(替卡西林/棒酸、哌拉西林、复方新诺明除外)。结论驻军附近鸭绿江江水细菌种类繁多分布广泛,对抗菌药物耐药率低,开展江水细菌调查及耐药性监测,对江水细菌感染的防治及耐药菌的传播具有重要意义。

Surveillance of the distribution and drug-resistance of the bacteria in the water of Yalujiang River of Sino-korean border

Objective To reduce non-battle casualties of soldiers due to environmental pollution,it might be necessary to understand the bacterial species,its distribution and bacterial sensitivity to antibiotics near the Yalujiang River barracks.Methods Collect samples of water from 15 different water areas of the Yalujiang River,each location with three copies.The bacterial species in the 45 water samples were cultured and isolated for bacteriological identification and antibiotic sensitivity tests by automatic microbial analyzer.Results 218 strains of 45 kinds of species of bacteria were isolated,including 88 strains of Enterobacteriaceae(44.89%),52 strains of non-fermenting bacteria(26.53%),50 strains of the Vibrionaceae bacteria(25.51%),and 22 strains of Gram-positive cocci(10.09%).Susceptibility testing results show that sensitivity rate of the 88 strains of Enterobacteriaceae to imipenem,meropenem,piperacillin/tazobactam,cefoperazone/sulbactam,cefepime,amikacin was 100%,while sensitivity rate of which to third generation cephalosporins,Quinolone,aztreonam Nanmin was 85.95%.The sensitivity rate of non-fermenting bacteria to all those antibiotics was 95%-100%.As for Vibrionaceae,the sensitivity rate was 95%-100%(with the exception of ticarcillin/clavulanic acid,piperacillin,co-trimoxazole).Conclusion There could be a wide range of bacterial species in the Yalujiang River near the garrison,widely distributed,with a high sensitivity to antibiotics.Carrying out the river bacterial investigation and surveillance of antimicrobial resistance might be of great significance for the prevention and treatment of river bacterial infection and the spread of resistant bacteria.
