Hyphae and swollen cells resembling chlamydospores were observed in the scrapings of skin lesion of the experimental infection of the rabbit.

The morphological characteristic showed that the colonies were black green and the hyphae were septum, brown, Spore size was 11.07×25.18μm, mostly ellipse, with three septate , two central cells were larger than both terminal cells , brown to dark brown , terminal cells subhyaline to light Brown after cultured on PDA medium at 5d. The DNA sequence of ribosomal ITS of the isolates was found to match 99% with an ITS sequence of Curvularia verruculosus in GenBank.

为致病菌。该菌在PDA培养基上培养5d后，菌落呈墨绿色，菌丝褐色，有隔，分枝，分生孢子平均大小为11.07×25.18μm，褐色至暗褐色，椭圆形，具有3个隔膜，主隔膜明显加粗，中间两细胞较大。rDNA-ITS测序结果与GeneBank中的序列进行同源性比较发现菌株与Curvularia verruculosus的同源性高达99％。

It is indicated that chimozine is relative to the forming of peritrophic membrane and the den-sity of PMb determined whether Nosema Apis Zander can inject in the ventriculus epithelium.

Methods Study the effect of G. lucidum spores oil (at the dose of 2.5,1.25,0.725 g/kg) on reducing the toxicity of the Cy chemotherapy and 60Co radiotherapy by detecting the number of the peripheral blood leucocyte, the number of bone marrow karyota;spleen index, thymus index of normal mice and H22-bearing mice by carbon clearance test and serum erythrocytolysin test. Results It showed that G.
