Morphology and end product patterns were used to group 112 bacterial isolates from the ceca and colons of pigs fed unmedicated and chlortetracycline-containing diets. Most of the isolates (68%) were resistant to chlortetracycline (greater than 4 micrograms/ml). Chlortetracycline resistance was associated with all groups of anaerobic and facultative bacteria.
利用形态学和终产物模式对来自饲喂未加药日粮和含金霉素日粮的猪的盲肠和结肠中的112株细菌分离株进行分组。大多数分离株(68%)对金霉素耐药(大于4微克/毫升)。金霉素耐药性与所有厌氧和兼性细菌组有关。
