根据科赫氏法则从接种发病植株叶片上分离病菌，其形态特征与从自然发病植株上分离的相同，证实这些菌株就是棉花叶斑病的致病菌，其中链格孢属是棉花叶斑病的主要致病菌属 3。

Considering the importance of oxalic acid in pathogenicity, germin, an oxolate oxidase, was used in S. sclerotiorum resistance of crops breeding study.

Four field strains of infectious bronchitis viruswere isolated from chicken kidney, trachea and lung of the young layer flocks in some regions of Shaanxi province. Biological characterizations of the virus were investigated by virus pathogenicity to chicken embryo and healthy chickens, hemagglutination test, hemagglutination inhibition test, dwarfing embryonated chicken eggs, electron microscopy and reverse transcription polymerase chain reaction. It demonstrated that allantoic fluid of each passage virus could hemagglutinate chicken red blood cells by treatment with 1% trypsin. The standard positive serum to IBV could inhibited the hemagglutination. The isolates could make respiratory and kidney diseases in chickens.

采集陕西省宝鸡市、扶风县、兴平市和榆林市等地鸡场疑似传染性支气管炎发病鸡病料，通过9～11 日龄非免疫鸡胚进行了病毒的实验室分离和传代，并对分离毒株进行了病毒的血凝性、血凝抑制性、致病性、鸡胚矮小化、电镜特征等生物学特性鉴定，结果表明，4 株分离株经1%胰酶处理后的各代病毒尿囊液均可凝集鸡红细胞，标准阳性血清可特异性的抑制其凝集性，回归试验可复制出与自然发病相同的病例，病毒传代物有明显的致鸡胚矮小化作用，透射电镜下可见有近似球形、直径100 nm左右的冠状病毒粒子，将分离鉴定的4 株IBV 定名为BJ-04、FF-04、XP-03 和YL-04。

Cases of tumor was performed by immunohistrochemical staining EMA and Vim were positive. 12 cases were hyperplasic lesions of mesothelial cell. Induced rats' MPM had a higher similarity with human' s MPM, especially in pathogenicity, positions, histological type and biological behavior of invasion and metastesis.

结果 实验组发生胸膜间皮瘤66例，诱发率71.74%，大体形态肉眼结节型间皮瘤较多见（72.73%）组织形态可见上皮型、梭形细胞型及混合型双向多潜能分化，13例免疫组化EMA及Vim双向阳性，并可见12例胸膜间皮细胞增生性病变，诱发瘤在病因，发病部位，组织形态学以及浸润转移的生物学行为方面与人体间皮瘤极为相似。
