摘要(Abstract):

本文报导了70株鼠伤寒沙门氏菌的药敏及R质粒的检测结果。其小有40株(57.2%)对一种或一种以上抗菌药物耐药,三耐以上的多重耐药菌株占80%(32株/40株)。40株耐药菌株中的可传递性R质粒检出率为32.5%。7耐菌株中携带R质粒的占35.7%(10/28),示带耐药标志越多,R质粒的阳性率越高。
The results of detection of drug resistance and trasmissible R plasmids of 70 strains of Salmonella typhimurium collected from Guiyang and Zunyi are re- ported. Fourty of 70 strains (57.2%)were drug-resistant to one or more drngs. Of these, 32 (80%) were drug-resistant to streptomycin, chloramphenicol, tet racycline, gentamycin, kanamycin, ampicillin and neomycin. Among the 40 drug-resistant strains. 5 patterns of drug resistance were found. All drug-re- sistant strains were tested for transferring resistance to E. Coli K12 W1485 F- Rifr. Thirteen of 40 drug-resistant strains (32. 5%) were transferring direc- tly, and 9 strains were transferring the complete resistance spectrum.
