苄青霉素

Isolates CNR-1 and CNR-2 were from Brassica napus; CNA-1and CRW-1 from Rhododendron simsii and Oxalis corymbosa respectively. All isolates grew well in R-2 liquid medium and exhibited contractive movements. The colonies of all isolates were circinal and grain-like in solid medium. Through electron microscopy, all isolates exhibited helicity during their growth phase. All isolates could pass through a 0.22 μm filtrate membrane and resist to penicillin (2000 U/mL). They must grow in medium with serum.

这4株螺原体在R-2液体培养基中生长良好，都能通过孔径为0.22 mm的微孔滤膜；在R-2固体培养基上呈圆形或颗粒状菌落，菌落直径约50~600 mm；在生长的某个阶段可呈典型的螺旋状，菌体直径为37.04~370.40 nm，长度约0.89~11.88 mm；它们都能利用葡萄糖作为碳源，不能利用尿素；在不含胎牛血清的R-2培养基中，它们都不能生长；菌株CNR-1、CNA-1能强烈代谢精氨酸，而CNR-2和CRW-1不能代谢精氨酸；在氨苄青霉素钠浓度高达2000 U/mL的R-2培养基中，分离菌株生长良好。

A comparision of pharmacokinetic studies of benzylpenicillin in healthy ( n=8 )and artificially Streptococcus suis infected (n=6 )pigs were reported.

本文报道苄青霉素在健康猪(8头)和人工感染猪链球菌病猪(6头)体内代谢动力学的比较研究。

The isolate grew well in R2 liquid medium and could pass through 0.22 μm and 0.45 μm filtrate membranes. The colony was grain-like in solid medium. Through electron microscopy, the isolate YY0801 exhibited helicity during their exponential growth phase. The isolate YY0801 was able to ferment glucose and D-fructose and to catabolize arginine, but did not to hydrolyse urea. The isolate was resistant to ampicillin (2000 U/mL).

分离菌株在R2液体培养基中生长良好，能通过孔径为0.22 μm、0.45 μm的微孔滤膜；在R2固体培养基上呈颗粒状菌落；在对数期呈典型的螺旋状；能利用葡萄糖、D-果糖作为碳源；能强烈代谢精氨酸；不能利用尿素，在含氨苄青霉素钠(2000 U/mL)的R2液体培养基中生长良好。

The multi-copy expression vector pZM is a shuttle plasmid which can replicate in Escherichia coli, Streptomyces and S. erythraea. It contains PermE promoter, fd terminator, multiple clone site, thiostrepton and ampicillin resistance genes, and ColE1 ori and pJV1 ori replicons which make the vector replicate in E.

游离型多拷贝表达载体pZM是可以在大肠杆菌、链霉菌和糖多孢红霉菌中扩增的穿梭型质粒，带有PermE启动子、fd终止子、多克隆位点、硫链丝菌肽和氨苄青霉素抗性基因以及在大肠杆菌和糖多孢红霉菌中复制的ColE1 ori和pJV1 ori复制子，载体大小9880bp。

Blood samples were collected at different intervals after the drug ( 15000IU/kg ) was intramuscularly injected.

按每公斤体重肌肉注射15000单位苄青霉素后，不同时间采血，用微生物法测定血清药物浓度。

Western blotting confirmed that the low activity of b-lactamase in E. coli Top10 pcs+ resulted from a lower amount of b-lactamase in its periplasm.

由此可见，周质内低含量的b-内酰胺酶是导致E.coli Top10 pcs+细菌氨苄青霉素抗性降低的原因。

The cylinder plate microbiological assay method with Sarcina lutea was used for the determination of ampicillin residues in tissues of pigs and chickens.
