The coliform bacterial population in the Grand Forks, N.Dak. sewage system was examined for multiple-antibiotic-resistant organisms over a 1-year period. Multiple-antibiotic-resistant coliforms were found to be common in the sewage, and their numbers remained fairly constant relative to the total coliform population throughout the year. Resistance to kanamycin, tetracycline, and ampicillin was found to be transferable at variable rates. Transfer rates were found to be temperature sensitive and were optimal at 35 degrees C. Although 75% of the multiple-antibiotic-resistant coliforms were capable of transferring resistance at some level, only 25% were capable of transferring resistance at rates greater than 10(-3) transconjugants per initial donor.
在北达科他州大福克斯市的污水系统中,对大肠菌群细菌群体进行了为期一年的多重抗生素抗性生物体检测。发现多重抗生素抗性大肠菌群在污水中很常见,并且相对于全年的总大肠菌群数量,其数量保持相当稳定。发现对卡那霉素、四环素和氨苄青霉素的抗性能够以不同速率转移。转移速率对温度敏感,在35摄氏度时最为适宜。虽然75%的多重抗生素抗性大肠菌群能够在某种程度上转移抗性,但只有25%能够以高于每初始供体10(-3)个转接合子的速率转移抗性。
