Sequence comparisons showed that it shared 71.5%～99.1% homology with isolates of sugarcane mosaic virus, 67.8%～68.5% with sorghum mosaic virus and 38.4%～48.4% with maize dwarf mosaic virus, indicating that the pathogen of this disease on maize in Hangzhou was sugarcane mosaic virus.

病毒RNA13'端序列(1.8kb)与甘蔗花叶病毒同源性最高，达 71.5 %～ 99.1%，与高梁花叶病毒同源性次之，为 6 7.8%～ 6 8.5 %，与玉米矮花叶病毒同源性最低，仅为 38.4%～ 48.4%，从而初步认为此病害由SCMV引起。

Anguillarum isolates, while 94.3% and 91.9% nucleotide identical to L. pelagius and Photobacterium damselae respectively. MP analysis showed that ayu-H080701 shared 97.6%-98.8 % amino acid sequence identical to L. anguillarum isolates, while lower than 75.6 % to other bacteria. Phylogenetic analysis showed that ayu-H080701 grouped constantly with L. anguillarum isolates. The biochemical, physiological tests and sequence analysis all strongly supported the identification of the pathogen causing ayu vibriosis in Ninghai country, China, as an isolate of L.

PCR扩增检测表明，细菌16S rRNA 基因通用引物和鳗利斯顿氏菌MP基因特异引物均能扩增到预期大小的特异性条带。ayu-H080701与鳗利斯顿氏菌16S rRNA基因核苷酸序列同源性最高，为99.4%～99.5%，与同属的海弧菌和美人鱼发光杆菌分别为94.3%和91.9%；ayu-H080701与鳗利斯顿氏菌MP氨基酸序列同源性高达97.6%～98.8 %，与其它弧菌科成员则低于75.6 %，系统进化树分析也揭示ayu-H080701与鳗利斯顿氏菌进化相关性最高。

Phylogenic analysis based on entire S1 gene sequences showed that majority isolates clustered together with the close phylogenetic relationships. Therefore, we researched pathogenicity of the selected isolate IBV CK/CH/LDL/05II in this group, Pathogenic study showed that this virus caused 100% morbidity and 54.5% mortality to 15-day-old specific-pathogen-free.The kidneys from the dead chickens showed the predominant gross lesions which were pale, mottled, and swollen. The renal tubules and ureters were distended with excess urates.

经S1基因系统进化树分析发现，本实验所分离的大多数IBV毒株(8/12)分布于同一基因进化群内，并且亲缘关系较近，因此，我们对此群中IBV毒株CK/CH/LDL/05II的致病性进行研究，以10~(5.5)×EID_(50)/0.1ml的病毒接种15日龄的SPF雏鸡，鸡群发病率为22/22(100%)，死亡率为12/22(54.5%)，死亡鸡以肾脏肿大、苍白、外观呈现典型的&花斑肾&，肾小管和输尿管扩张并且有尿酸盐沉积为主要病理变化。

Alternaria zinniae was a plant fungal pathogen isolated from a world-wide weed Xanthium occidentale, which could cause some weeds of Asteraceae disease. It was found that the fungus made disease spot on the leaf through producing secondary metabolite--phytotoxin.

百日草链格孢菌是从世界性恶性杂草苍耳罹病植株上分离得到的植物病原真菌，研究表明该菌对紫茎泽兰有致病作用，可产生致病的次生代谢产物--毒素。

Methods The sicked pigs were studied on examination of pathogen, investigation of epidemiology included different ages, species and seasons, observation on clinical symptom, pathology, artificial infections and treatment.

The genetic study suggested that the carbendazim-resistance in these mutants could be steadily inherited by asexual and selfed reproduction, and the resistance was controlled by the same single major gene both in laboratory mutants and field resistant isolates, the different levels of resistance or the same resistant level in different strains maybe conferred by mutations at different sites or one site with different allelic mutations. The gene compensates for the sensitivity to MDPC was allelic to that governs the carbendazim resistance, but the mutation for increasing sensitivity to MDPC in this gene could get the pathogen highly resistant to carbendazim.

抗药性遗传研究表明，在所研究的抗药突变体中，抗药性在自交和无性繁殖后代中能稳定遗传；室內抗药突变体和田间抗药菌株对多菌灵的抗药性由同一个主效基因控制，但它们发生突变的位点不同或者同一碱基位点发生了不同的突变；对MDPC的敏感性也是由单个基因控制的，该基因与控制多菌灵抗性的基因是等位基因，当该基因发生对MDPC的敏感性增加的突变时会使病菌对多菌灵产生高水平抗性。
