致病性

Moreover, no significant changes in flagellar mobility, biofilm formation and production of extracellular cellulase and xylanase in vitro were observed in △rbfCxoo compared to PXO99A. Most importantly, the deletion mutation of rbfCxoo resulted in enhanced virulence and gene expression.

此外，△rbfCxoo鞭毛运动性、生物膜形成和胞外纤维素酶和木聚糖酶活性都无明显改变，但对水稻的致病性显著增强，毒性相关基因的表达也有所增加。

Severe complications arising from influenza virus infection （pandemic influenza or the highly pathogenic avian H5N1viruses） are often associated with rapid, massive inflammatory cell infiltration, acute respiratory distress, reactive hemophagocytosis and multiple organ involvement.

流感病毒感染（如暴发性流行或高致病性禽流感H5N1感染）可以造成广泛的病理损伤及严重的并发症，其肺部病理损伤以肺水肿及广泛的炎性渗出为特点，并伴有人量的中性粒细胞、巨噬细胞、淋巴细胞浸润及促炎因子和趋化因子的产生。

Gloeosporioides is an aggregative species and has differentiation within species, the pathogen probably is a microspecies under C. gloeosporioides and exhibited some specialized and selective qualities in pathogenicity. According to its symptom, the disease was named as angular leaf spot.

由于胶胞炭疽菌是1个集合种，存在分化现象，该病原菌可能是分化出的1个小种，并在致病性方面表现出一定的专化性或选择性，根据该病害的症状命名为板栗角斑病。

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。

Results: The foodborne diseases caused by Pathogenic Vibrios accounted for 58.57%.

结果：由致病性弧菌引起食源性疾病占58 。57%。

An insect resembling a member of the order Coleoptera.

组织或细胞内，一些虫种为共栖性的，而另一些是致病性的。。。。

The pathogens of Elsinoe ampelina were isolated and purified from susceptible disease leaves of grape cultivar cultivated in Yangling, Shaanxi, China by the conventional tissue method. The total 24 strains of E. ampelina were obtained, and the strain YL108 was identified as the pathogens of E.

采用常规组织法对陕西杨陵葡萄黑痘病病原菌进行分离、纯化；共获得病原菌菌株24个；并对菌株YL018进行形态学鉴定、致病性测定及病原菌DNA同源性分析。
