Results Causing the pathogen of the infection regard the Green's surname feminine gender rod bacteria as principle,occupying 90.2%,the escherichia coli is the most familiar to occupy 65% the next in order for transform the rod bactenia,viceescherichia coli,sewerage intestine rod bacteria,etc.of aerobacter aerogenes.

结果：引起感染的病原体以革兰阴性杆菌为主，占90.2%，大肠埃希菌最常见占65％，其次为变形杆菌、副大肠杆菌、阴沟肠杆菌、产气杆菌等。

Bacterial forms with bacterial L-form transforms to L-forms and 1 strain of bacillus aerogen with its L-form.

结果：10例阑尾标本中均检出细菌型伴L型，其中9株为大肠杆菌伴L型，1株为产气杆菌伴L型。

Chickens were experimentally infected with Mycoplasma gallisepticum and Escherichia coli via the air sac.

雏鸡气囊人工混合感染鸡毒支原体和大肠杆菌。

Result: Lincomycin and Spectinomycin, 0.75-1.88g/ l of the drink water for 5 d, can availably control chicken infection, and reduce incidence of the disease, air sac pathological c...

结果 ：林可-大观可溶性粉按 0 。75～ 1 88g/l饮水治疗 5d ，能有效地控制雏鸡大肠杆菌及支原体感染，降低感染鸡发病率、气囊病变指数、支原体抗体阳性率和死亡率；其效果与对照药物利高霉素 10 0相近

The results showed: the Berberis heteropoda pigment could effectively inhibit the growth of theE scherichiac oli, the calyx pigment ofP hysalis alkekengi coulde ffectively inhibit the growth of the Bacterium proteus, the concentrated liquid of Rhodiola sachalinensis could effectively inhibit the growth of the Bac.

结果发现：小檗色素对大肠杆菌抑菌作用最强，酸浆花萼色素对变形杆菌抑菌作用最强，红景天浓缩液对枯草芽孢杆菌抑菌作用最强，小茴香浓缩液对四种待试菌无抑菌作用；小檗色素对四种待试菌的最低抑菌浓度和最低杀菌浓度分别为：枯草芽孢杆菌MIC2。

MethodWith Staphylococcus aureus,Escherichia coli and Bacillus subtilis as tested bacterium,the bacteriostatic effects of ethanol extracts from Alsophila spinulosa leaves and stems on 3 kinds of bacteria were studied and compared with that of coptis extracts.

方法以金黄色葡萄球菌、大肠杆菌、枯草芽孢杆菌为供试菌种，研究了桫椤茎叶和茎干甲醇提取物对它们的抑菌作用，并与黄连提取物的抑菌效果进行比较。

Cloning of the Schwanniomyces occidentalis α-amylase and high expression in S.cerevisiae.The E.coli / yeast shuttle plasmid YCEpl partial library of Schwanniomyces occidentalis DNA was constructed and α-amylase gene fragments were screened in Saccharomyces cerevisiae by amylolytic activity.Several transformants with amylolysis were obtained and one of the fusion plasmids has about 5.0 kb inserted DNA fragment.It contains the upstream and downstream sequences of α-amylase gene from S.occidentalis .

以E.coli/yeast穿梭质粒YCEp1为载体构建西方许旺酵母部分基因组文库，在大肠杆菌中扩增后提取混合质粒DNA，经电转化非缺陷标志酒精酵母 AS.2.1364，在YPDS平板(含1%葡萄糖和1%可溶性淀粉)上用淀粉水解活力筛选含水解淀粉的阳性转化子，从阳性转化子中分离重组质粒证实含5.0kb的插入片段，用α-淀粉酶基因两端序列设计的引物PCR扩增及扩增片段序列分析证实该片段中含有α-淀粉酶全部编码序列。

Futher results showed that: the optimum growth temperature for the 4 lactic acid bacteria was 30℃; and the pH 3.5~4.0; all 4 lactic acid bacteria could grow at the medium with 10% NaCl, and the optimum range was 2%~6% They were aerotolerant anaerobe; They showed certain inhibition on E coli..

进一步测试表明：4株乳酸菌在30℃培养时，生长最好；在pH3.5~4.0时生长良好；4株乳酸菌在10% NaCl的环境中均能生长，其中以2%~6%的NaCl浓度内生长最适宜；属兼性厌氧菌；对大肠杆菌产生一定的抑制作用。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
