摘要
在实验室内对流行区分离到的伤寒杆菌进行了理化因子抗力测定。结果发现,所测氯霉素耐药株对理化因子的耐受力略强于氯霉素敏感株,但因测试菌株少,尚不足以作规律性结论。
Resistance of Salmonella typhi isolated from epidemic area to physical and chemical agents was tested in laboratory. Four strains were tested. Of them, strains No. 2, No. 42 and No. 44 were resistant to chloromycetin, while strain No. 14 was chloromycetin-sensitive. The results indicated that the bacteria did not grow at 65℃ for 5～10 min or 100℃ for 1 min and its number decreased significantly after ultraviolet irradiation. For chemical disinfectants, 75% ethanol with a 30 sec contact time, 30% lysol or 0.01% bromogeramine with a 1 min contact time, or 0.1%peracetic acid with a 2 min contact time could kill completely S. typhi in suspension. The resistance of chloromycetin-resistant strain of S. typhi to physical and chemical agents was slightly higher than that of chloromycetin-sensitive strain, but this is not conclusive since only a few strains have been tested.
