A total of 704 Salmonella strains isolated from various sources were tested for their resistance to chloramphenicol. The results indicate that 36 out of 46 serotypes, comprising 671 strains (95.4%), were sensitive to chloramphenicol up to a level of 10 mug per ml of medium. Most of the strains were sensitive at concentrations between 2 mug and 4 mug of chloramphenicol per ml of medium. None of the strains isolated from animals, including poultry, was resistant. The results indicate that in India resistance of Salmonella strains to chloramphenicol has not increased over the years though this may have occurred in other parts of the world.
共检测了从不同来源分离出的704株沙门氏菌对氯霉素的耐药性。结果表明,46种血清型中的36种,共671株(95.4%)对每毫升培养基中高达10微克的氯霉素敏感。大多数菌株在每毫升培养基中氯霉素浓度为2微克至4微克时敏感。从包括家禽在内的动物中分离出的菌株均无耐药性。结果表明,在印度,沙门氏菌菌株对氯霉素的耐药性多年来并未增加,尽管世界其他地区可能已经出现这种情况。
