重庆地区沙门氏菌耐药变迁及临床疗效观察

STUDIES ON THE CHANGES OF ANTIBIOTIC RESISTANCE OF SALMONELLA AND THEIR THERAPEUTIC IMPLICATIONS IN CHONGQING DISTRICT

本文报道了重庆地区1984～1988年沙门氏菌对32种抗菌药的敏感度试验、30年来的耐药变迁及伤寒与耐药伤寒的临床疗效观察。表明耐药伤寒杆菌对常用于治疗伤寒的抗生素如氯霉素、SMZ/TMP、氨苄青霉素及其它药物产生了不同程度的耐药性。

This paper reports the changes in susceptibility of Salmonella spp. to 32 antimicrobial agents from 1959 to 1988. The clinical observation on the treatment of typhoid fever caused by drug-sensitive and resistant strains of S. typhi arc also reported. Resistant Salmonella began to appear from the year of 1986. The in vitro studies indicated that drug-resistant S. typhi were resistant to commonly anti-typhoid agents such as chloramphenicol, SMZ/TMP, ampicillin and other drugs, but were very sensitive to new quinolones and the third generation cephalosporins. The .therapeutic effects correlate well with the in vitro sensitivity tests. Typhoids caused by drug-sensitive strains responded well when treated with chloramphenicol, SMZ/TMP or ampicillin, while those caused by resistant strains only responded well to norfloxacin or its combi-nation with other drugs
