A total of 231 thermotolerant coliforms was isolated from rural drinking water from four states of India. Of these, 220 isolates were resistant to ampicillin, chloramphemicol, streptomycin and tetracycline. Multiple (MAR), double and single antibiotic resistances were observed in 31.4, 48.6 and 13.7% of the isolates, respectively. Out of 177 antibiotic-resistant isolates examined for transmissibility, only 15.3% were able to transfer their resistances to Escherichia coli K-12 recipient. The resistances were transferred by 32.5% of MAR, 21.9% of double resistant and 7.6% of single resistant isolates. Ampicillin resistance was transferable in 14.69% strains while resistances for the rest of the antibiotics were transferable in less than 4% strains. MAR strains of E. coli and Klebsiella sp. showed highest levels of R-plasmid transfer.
从印度四个邦的农村饮用水中总共分离出231株耐热大肠菌群。其中，220株分离菌对氨苄青霉素、氯霉素、链霉素和四环素具有抗性。分别在31.4%、48.6%和13.7%的分离菌中观察到多重（MAR）、双重和单一抗生素抗性。在检测其可转移性的177株抗生素抗性分离菌中，只有15.3%能够将其抗性转移至大肠杆菌K-12受体菌。MAR分离菌中有32.5%、双重抗性分离菌中有21.9%以及单一抗性分离菌中有7.6%能够转移抗性。14.69%的菌株可转移氨苄青霉素抗性，而其余抗生素的抗性可在不到4%的菌株中转移。大肠杆菌和克雷伯菌属的MAR菌株显示出最高水平的R质粒转移。
