目的:了解浑江中上游水中细菌的种类及分布情况。方法:采集浑江中上游不同水域的水样,经增菌培养、细菌分离,进行细菌学鉴定。结果:从浑江中分离出细菌387株,其中肠杆菌科细菌189株(59.1%),弧菌科细菌4l株(12.8%),非发酵菌35株(10.9%),革兰阳性杆菌29株(9.1%),革兰阳性球菌26株(8.1%)。结论:浑江中上游细菌种类多、分布广泛,此项调查对于该水域细菌感染的防治具有重要意义。 Objective: To understand the species and distribution of bacteria in the upper and middle reaches of the Hunjiang River. Methods: Water samples of different waters in the middle and upper reaches of the Hunjiang River were collected and enriched for bacteria culture. The bacteria were separated and identified by bacteriology. Results: 387 strains of bacteria were isolated from Hunjiang River, including 189 strains of Enterobacteriaceae (59.1%), 4l strains of Vibrio (12.8%), 35 strains of non-fermentative bacteria (10.9%), Strain (9.1%), Gram-positive cocci (26 strains) (8.1%). Conclusion: There are many bacterial species in the middle and upper reaches of the Hunjiang River, and the survey is of great significance for the prevention and control of bacterial infection in this area.
