Results: 41 patients had lower tract infection,24 were G- bacillus patients,accounted for 63.4%,15 were G+ coccus,accounted for 36.6%,11 were staphylococcus patients,bacteria drug resistance was higher among these patients.

结果：重症脑出血微创术后气管切开病人下呼吸道感染41例，其中G-杆菌26例占63.4%，G+球菌15例占36.6%，其中金葡菌11例，药敏仍以敏感菌株为主，但耐药菌株有增多趋势。

ABSTRACT Objective: To investigate active efflux of drugs in clinical isolated strains of Escherichia coli.

目的：研究临床分离的大肠杆菌多重耐药株和敏感株中抗菌药物的主动外排系统。

Nit mutants could be selected from chlorate-resistant sectors on Czapek but not on minimal medium . A total of 328 stable nit mutants were selected from 3504 sectors on Czapek and used for the further study. Of these nit mutants, 58. 8% were classed as nit1, 26. 8% as nit3, 13. 8% as NitM, 0.6% as nitD unable to from each isolate were complementally paired in all possible combination.

全部3504抗氯酸盐突变体在Czapek中共鉴定出328个稳定的nit突变体，其中nit1占58.8％，nit3占26.8％，NitM占13.8％，nitD占0.6％。37个菌株中，21个（73％）获得了nit突变体，16个（26％）还没有，仅5个菌株获得了NitM突变体。

In addition, complementation of minE gene in minE mutant strain, approximately 41% bacterial cell length was restored.

此外，在minE的互补株中，有41%的菌体长度能回复成野生株的形态。

The results showed that the best substrate of weight ratio of bran was that grain pieces∶ cornmeal was 2∶1∶1.Most quantities of sporulation and antifungal compound on spore germination of Verticillium dahliae were analyzed.Accumulation of antifungal compound was in direct proportion to the quantities of sporulation in the solid fermentation conditions.The solid ferment...

结果初筛出最佳固体发酵基质配方为麸皮：豆粕：玉米粉比为2：1：1；发酵温度、料水比、pH值、接种量等对菌株产芽孢及其抗菌物质的分泌有明显影响；在固体发酵条件下，芽孢的产生数量与抑菌物质的积累呈正比，以温度为35℃，料水比为1：1.4，pH值为7.0，接种量为10%为菌株最佳发酵条件。

Pathogens were isolated from diseased leaves of Atractylodes in Xiaochang county of Hubei province. Firstly, we pathogenicity test was conducted based on Kochs rule. Secondly, we described the morphological characteristics of the conidia, conidiophore and beak of the pathogens growing on diseased leaf land PCA.

从湖北省孝昌县苍术种植基地的发病植株叶片上分离得到菌株，根据柯赫氏法则对分离自发病叶片的菌株进行致病性测定，然后描述了寄主发病叶片以及PCA培养基上分生孢子、分生孢子梗及喙的形态，测量其大小，观察分生孢子链的形状。

A planting density of 3,332 plants per hectare can also be obtained planting 1 corm per hole at spacing of 1.5×2 m.

按1.5m×2m的方式，每穴种一株也可以获得3332株/公顷的种植密度。

About 18 Haemophilus paragallinarum strains were isolated and identified in different sites, there are 3 B serovar strains in them, indicating the new epidemiological characteristics of infectious coryza in China.

2001年至2003年通过从不同地区的免疫失败鸡场分离到18株副鸡嗜血杆菌的血清型鉴定，有3株为B血清型，说明我国鸡传染性鼻炎的流行已经出现了新的特点。

It is reported in this study that (1) two high enzyme-yeilding strains TK54 and T12 have been screened from four choleterol-secrecting experimental strains, he supernatant of which have been tested for insecticidal activity with the results showing that cholosterol oxidase can strongly inhibit the vigor of cotton boll worm.

本研究从4个分泌胆固醇氧化酶的实验菌株中，筛选出两个高产酶菌株TK54和T12，用其上清进行杀虫实验发现，胆固醇氧化酶具有较强的抑制棉铃虫生长的活性。

We take biodegradation experiments toward three colonies with different density phenolic waster water, and test their rate of phenolic degrading and speed of bacteria growth in different time period. The results show that the rates of pheolic degrading are more than 95% in 500mg/L phenol and 250mg/L cresol culture solution.

对这三株菌种进行不同浓度的含酚废水降解试验，测定其不同时间段的酚降解率和菌株生长速度，结果表明BP-1，BP-2，BP-3菌在500mg／L的苯酚，250mg／L的甲酚溶液中的降酚率均达到了95％以上。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
