The most common causative strain of gallstone pancreatitis is Bacterium coli. The drug-resistant strain emerges maybe due to bacterium immigration and delitescence in gallbladder mucosa.

胆源性胰腺炎感染细菌主要以大肠杆菌为主，耐药菌株的出现可能与细菌向胆囊黏膜迁移并发生变异，以L型细菌的形式潜伏于胆囊有关。

When heterotrophic bacteria were washed out while autotrophic bacteria were accumulated, the sludge mainly was bacilliform floccule, but the sludge was petallike when the steady nitrification was set up and part nitrogen removal function was reached. The lack of organic carbon source made autotrophic bacterium become the dominates and the microbial community structures become simple.

经过成功启动并稳定运行后，单级自养脱氮系统内随着反应器内有机碳源的减少，系统中自养细菌在同异养细菌的竞争中逐渐占据优势地位，适应能力较弱或对有机碳源量要求较高的异养细菌则被大量淘汰，微生物群落结构与接种污泥相比已变得简单且较稳定，种群多样性降低。

Experimental results show the lag phase of Thiobacillus ferrooxidans was longer and bacterium density was decreased when 0.25% pulp density of metal sulfides or 1% element sulfur was added in 9K medium.

同时研究了多种因素对氧化亚铁硫杆菌生长活性的影响，发现在Fe〓氧化体系中添加0.25％固体物浓度的硫化矿物时，细菌的Fe〓氧化速度会降低，细菌生长停滞期延长，浸出液中细菌浓度减少。

It is associated with bacterial motility and plays an important role in bacterial infection and immunity as well as classification.

它是细菌在进化过程中长期适应的结果，使细菌更好地适应环境，有利于细菌的生存。

Totally 104 samples were bacteria positive, 66 strains being G^＋ cocci and 34 strains G^- bacilli.

患者刚人院时，细菌以革兰阳性菌为主，随着患者住院天数的延长，细菌的种类也发生变化，在医院感染病例中细菌的分布是以革兰阴性菌为主；应加强抗菌药物使用和监控，根据药敏结果合理选用抗菌药物。

Bacillus subtilis str. B5423, Pseudomonas fluorescens str. Pf7-14, nonfluorescent pseudomonads str. P13 are antagonistic to rice sheath blight. Resistance to antibiotic is the character that was chosen to use to mark the strains in order to monitor the population dynamics of the strain on the surface of rice plant and to elucidate the mechanism of suppressing the diseases.

Results indicate that the number of bacteria grown in media LB, CSEA and WSA was 14.84×10^7, 10.27×10^7 and 6.91×10^7 CFU per gram dry soil, respectively, after 192 h of incubation. The diversity index of soil bacteria was the highest in WSA, while the lowest in LB. Certain similarity was discovered in bacteria community between the three media, i. e. the Jaccard index was 57.69% between LB and CSEA, 53.13% between LB and WSA and 66.67% between CSEA and WSA. Phylogenetic analysis suggests that the dominant bacterial groups in the soil belong to β-Proteobacteria,γ-Proteobacteria and Actinobacteria. The sequence of 16S rDNA of some OTUs was found to have high homology with Burkholderiaceae bacterium, Rhodococcus and Mycobacterium, so it is presumed that the cells of these bacteria can secrete Resuscitation-Promoting Factors, which may effectively improve culturability of soil microorganisms.

结果表明，LB、CSEA、WSA培养基192h后每g干土获得的细菌数量分别为14.84×10^7、10.27×10^7和6.91×10^7CFU，但微生物多样性指数以WSA为最高，LB多样性指数最低；三种培养基培养的细菌菌群有一定的相似性，LB和CSEA培养基间的Jaccard指数为57.69%，LB和WSA培养基之间为53.13%，而CSEA和WSA培养基的相似性指数达66.67%；16SrDNA测序结果表明，所获得的土壤细菌优势种群在分类方面主要属于γ-和β-变形杆菌以及放线菌亚门，其中某些OTUs中的16SrDNA序列与Burkholderiaceae bacterium、Rhodococcus和Mycobacterium属具有较高的同源性，推测其细胞能够分泌复苏促进因子，有效地提高土壤细菌的可培养性。

Drought stress weakened the rhizosphere effect of ammonifying bacteria.Under drought stress,rhizospheric ammonifying bacterium amount of Baidan31 was very significantly different at seedling and jointing,and significantly different at tasseling-anthesis from that of control.Rhizospheric nitrifying bacteria tended to increase under drought stress.

干旱胁迫减弱了玉米氨化细菌的根际效应，与对照根际氨化细菌数量相比，白单31在苗期和拔节期根际氨化细菌数量受干旱胁迫的影响达极显著水平，在抽雄～开花期达显著水平；根际硝化细菌数量在干旱胁迫下有所增加。

Their saliva has antibacterial properties; it contains lysozyme, an enzyme that lyses and destroys harmful bacteria. Their short digestive tract is designed to push through food and bacteria quickly without giving bacteria time to colonize. The extremely acidic environment in the gut is also a good bacteria colonization deterrent. People often point to the fact that dogs shed salmonella in their feces (even kibble-fed dogs do this) without showing any ill effects as proof that the dog is infected with salmonella.

牠们的唾液有杀灭细菌的功能，其所含的成分可以很快制有害细菌为死地；牠们很短的消化道是的食物和细菌很快的通过，致使细菌没有繁殖的时间；胆道所分泌的高酸性胆汁也使有害菌没有生长的环境；人们也会发现在健康狗狗的排泄物中可以发现沙门氏菌（有些喂食狗粮的狗狗也会有），因而认定狗狗感染了沙门氏菌。

In order to obtain lactic acid bacteria using molasses wastewater to produce lactic acid,an activated sludge was sampled from bioreactor with molasses wastewater,and strain MD-9 was isolated by an anaerobic Hungate technique.

乳酸细菌是指一类能利用碳水化合物产生大量乳酸的细菌的通称，在细菌分类学上至少涉及23个属。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
