病原菌

Resistance responses were studied in different Arabidopsis ecotypes after being inoculated by some important plant pathogens. According to the results, molecular mechanisms of resistance and expression of the defense-related genes in resistance and susceptible Arabidopsis ecotypes were studied. Results followed in this paper.All the 11 Arabidopsis ecotypes tested were incompatible to Erysiphe convolvuli, Alternaria brassicicola, Setosphaeria turcica and Verticillium dahliae.

Results:The results showed that rate of the drug fast is very high. As the bacteria distribution ,the main pathogenic bacteria was the gram-negative bacilli(65.33 %), the second pathogenic bacteria was the gram-positive cocci(18.29%). and the mycetes(16.38%) occupied the third. In gram-negative bacilli the most were Pseudomonas aeruginosa,Acinetobacter baumannii,Klebsiella pneumoniae and Escherichia coli;Staph is the main pathogenic bacteria in gram-positive cocci;and in mycetes the main pathogenic bacteria were Candida albicans and Candida glabrate.

The pathogenic bacterium of prepartum and intrapartum infectious pneumonia mostly were G- bacilli,the pathogenic bacterium of postpartum infectious pneumonia mostly were G- bacilli and staphylococcus aureus.6.The drug resistant rates of G- bacteria to penicillins,cephalosporins,and monocyclicβ-lactam antibiotic were high,However,their compound of addingβ-lactamase inhibitor agents was relatively low resistance,and all G- bacteria were sensitive to carbapenem antibiotics.

产前及产时感染性肺炎的病原菌以G-杆菌多见，而产后感染性肺炎的病原菌主要为G-杆菌和金葡菌。6.G-菌对青霉素类、头孢菌素类及单环类的β内酰胺类抗生素耐药率高，但对其添加β内酰胺酶抑制剂的复合制剂耐药率较低，对碳青霉烯类抗生素均敏感；金葡菌对苯唑西林耐药率低，对万古霉素均敏感。7。

The E. coli, Pasteurella and Salmonella media were used to culture the isolated pathogenic bacteria in vitro. After culturing for some time, the growth of enteric pathogen colony on the 3 kinds of media was most obvious.

分别用大肠杆菌培养基、巴氏杆菌培养基和沙门氏菌培养塞对分离出的病原菌进行体外培养试验，培养一段时间后，来自肠道的病原菌在3种培养基上的菌落生长最明显。

Phytophthora sojae causing soybean Phytophthora root rot is one of the most devastating pathogens of soybean. It is also an important quarantine plant pathogen in China.

引起大豆疫霉根腐病的大豆疫霉菌是危害大豆的破坏性病原菌之一，也是我国重要的检疫性植物病原菌。

This paper discussed the pathogens, disease regularity and prevention countermeasures of maize stalk rot, and elucidated that the infection mechanism of maize stalk rot is primary infection source of Pythium spp under high temperature.

论述了玉米茎腐病的优势病原菌、发病规律及其防治对策，阐明了玉米茎腐病的侵染机制是腐霉菌在高温条件下主要的初侵染原，而镰刀菌因其超强的定殖能力而进行二次侵染，两种病原菌侵染致病的主要活性物质为糖蛋白毒素。
