These include a bacterial infection called Pierce 's disease , fungal infections such as mildews and rots , and viral diseases such as grape fanleaf virus and corky bark .

地，比如细菌致病的皮尔斯病，真菌感染的霉病和腐败，以及病毒性疾病如圆叶病毒和树皮干枯等。

The reason is that the state is home to diseases that clobber wine grapes. These include a bacterial infection called Pierce's disease, fungal infections such as mildews and rots, and viral diseases such as grape fanleaf virus and corky bark.

原因在于，这个州是葡萄树多种疾病的发源地，比如细菌致病的皮尔斯病，真菌感染的霉病和腐败，以及病毒性疾病如圆叶病毒和树皮干枯等。

Materials and Methods: 40 Sprague-Dawley Rats were divided into five groups at random. 8 rats served as normal control group. The remaining rats were given 5/6 subtotal nephrectomies to establish the model of CRF.

目的：观测慢性肾功能衰竭（Chronic Renal Failure， CRF）肾功能、肾脏病理和血浆丙二醛、超氧化物歧化酶，以及肾、心、小肠线粒体的改变，初步探讨CRF&肾小管高代谢学说&和&尿毒症毒素致病学说&的深层机理。

ABSTRACT:Nine proteins encoded by Mycobacterium tuberculosis RD1 region are important protective antigens that become absent in long passaging of Mycobacterium tuberculosis. They only exist in pathogenic Mycobacteria and are absent in Bacille Calmette-Guerin and environmental Mycobacteria. With good immunogenicities, they may play an important role in the diagnosis and prevention of Mycobacterium tuberculosis.

RD1区编码的9个蛋白，是结核分枝杆菌在长期传代过程中丢失的重要保护性抗原，仅存在于致病性分枝杆菌中，在卡介苗及环境分枝杆菌中缺失；其有较强的免疫原性，在结核病的诊断中发挥重要作用。

Amid a growing E. coli scare, Topps Meat Company is expanding its recall of frozen hamburger patties.

All C.neoformans contain serine protease; Serine proteinase perturbs the integrity of BMEC of the blood-brain barrier, improves open the level of BBB; Secreted serine protease from pathogenic fungi were virulence.

发现新生隐球菌分泌具有活性的胞外蛋白水解酶并含有丝氨酸蛋白酶成分；新生隐球菌自身分泌的丝氨酸蛋白酶可以干扰构成血脑屏障主要成分内皮细胞的完整性使得血脑屏障开放程度提高；致病性真菌分泌的丝氨酸蛋白酶可能是一种毒性因子。

Results there were94food poisoning events and1666total sufferers during3years,that is to say,about31.3events and555sufferers per year in average.1died in2003.the food poisonings occurred mainly in the second and third quarter of a year.baoan and nanshan are the most common strict where food poising oc-curred.communality food poison cases are the most common ones,in which the number is71and victims are1429.most food poi-soning cases were caused due to eating unsanitary meats and meat products.bacterium is the main factors resulting in food poisoning（60.6%）.vibrio parahaemolyticus is the first common pathogen of all the bacillary food poisoning（40.3%）.

结果 3年中深圳市共发生食物中毒94起，平均每年31.3起，1666人中毒，平均每年555人。2003年有1人死亡。中毒主要发生季节为每年第二、第三季度。宝安和南山为高发区域，共占53.2%，集体食堂引起的食物中毒起数和发病人数最多，分别为71起1429人。引起中毒的食品主要为动物性食品。食物中毒的致病因素60.6%为细菌性食物中毒，细菌性食物中毒中40.3%是由副溶血性弧菌引起，占细菌性食物中毒的第一位。

Diabetes mellitus (38.5%) and trauma (20.5%) were the most common predisposing factors.

糖尿病(38.5%)与外伤(20.5%)为最常见的致病危险因子。

We shall assume in the present case, that all these predisposing factors were such as to produce the story as we have told it.

我们将假设，在目前情况下，所有这些致病因素例如制作的故事，因为我们已经告诉它。
