tetracycline antibiotics 中文意思是什麼
-
The results indicated that all isolates exhibited a susceptibility to amikacin and ceftriaxon, and 67 isolates showed a greater or lesser degree resistance to streptomycin, kanamycin, gentamicin, ampicillin, tetracycline, chloramphenicol, florfenical, cefotaxime, cephalothin and ceftiofur, to which 22 isolates exhibited a susceptibility. some isolates showed resistance to multiple antibiotics and displayed a highest level resistance to streptomycin with a frequency of 43. 8 %, followed by tetracycline with a frequency of 30. 3 %
結果表明，所有分離菌株均對阿米卡星和頭孢曲松敏感； 67株對鏈黴素、卡那黴素、慶大黴素、氨芐西林、四環素、氯黴素、氟苯尼考、頭孢噻肟、頭孢噻吩、頭孢噻呋表現出不同程度的耐藥性，其中對鏈黴素的耐藥率最高，為43 . 8 ，其次為四環素（ 30 . 3 ） ，其餘22株為敏感菌株。 -
Considering alcaligenes faecalis pencillin g acylase ( afpga ), which possesses the attractive characteristics for beta - lactam antibiotics conversions, the gene of pga was cloned into two expressing vector pkkfpga and psmlfpga. both the constructed plasmids psmlfpga and pkkfpga contained the pga gene, trc promoter and rrnb transcript terminator, differ in the replicon and antibotic marker, pkkfpga contained multicopy replicon ( cole 1 ) and ampicillin marker. while psmlfpga contained medium - copy replicon ( p15a ) and tetracycline marker
本文將糞產堿桿菌青霉素g酰化酶（ afpga ）基因構建表達載體pkkfpga和psmlfpga ， pkkfpga和psmlfpga均含trc啟動子、青霉素g酰化酶基因、 rrnb轉錄終止子，其中pkkfpga含有氨卞青霉素抗性基因和cole1高拷貝復制子；而psmlfpga含有四環素抗性基因和p15a中拷貝復制子。 -
Penicillin, chlorampheicol, tetracycline, and various other antibiotics with or without streptomycin have also been needed with some degree of success under experimental conditions.
在實驗條件下曾用過青霉素、氯黴素、四環素和其它各種抗菌素（和或不和鏈黴素連用），得到某種程度成功。
