The results show that this strain was a typical acidophile with optimal growth pH being 2.0 for hypha and pH 3.0-4.0 for the spore germination. Peptone was the most suitable nitrogen source which helped produce xylanase induced by xylan during stationary phase. The resultant xylanase reacted best at 50℃-55℃ and pH 3.5, and had activities 70% after 60 min maintenance under optimum reaction conditions.

结果表明：实验菌株嗜酸，菌丝生长最适pH为2.0，孢子萌发生长适宜pH为3.0-4.0；木聚糖诱导菌体在生长稳定期大量产生木聚糖酶，蛋白胨是菌体产酶的适宜氮源；菌株所产木聚糖酶属于酸性木聚糖酶，反应最适pH3.5、最适温度50℃-55℃，在最适反应条件下保温60min，残余酶活仍接近70%，适用于较强酸性的高温加工环境。

Through all this test analyse Pathogenicity and Immunological status of ALV-J Inner Mongolia strain, the result showed the infected chickens began to have pathological change of Myelcytomatosis at 3-week: the main pathological changes of acidophile myelocyte were found in bone marrow and between cardiac muscle fibers,and there were many granules in the hyalotome.This kind of oncocyte proliferated in every tissue at different amount, but the cells that proliferated in bone marrow, cardiac muscle fiber, oarium were much more than other tissue, and they often developed neoplasma. At same condition,there were no abnormalty advent in control group, In immunological aspect: the increase of lymphokine and ANAE positive cells showed cell-mediated immunity was strengthend during antineoplastic infection; the emergence of ALV-J antibody of ELISA suggest there was humoral immunity exist at the same time.

结果显示：脾脏PCR检测结果表明1、2两实验组均有阳性病例出现，而对照组全部为阴性，说明实验鸡体内已有ALV-J内蒙株感染；接种病毒后3周龄开始出现骨髓细胞瘤病的病理变化：肝脏、脾脏有程度不同的肿大，镜下观察，骨髓内最早出现了与骨髓细胞相似、形态基本一致的大型圆形或椭圆形、胞核较大多为椭圆形、胞浆内含有大量嗜酸性圆形颗粒的髓细胞样瘤细胞增生，随后通过血流瘤细胞可转移到肝脏、心肌、卵巢或睾丸等组织并形成肿瘤性病灶，而对照组没有出现明显病变；免疫状态方面：以脾脏淋巴因子和ANAE阳性细胞增多说明细胞免疫在抗肿瘤感染过程中增强，ELISA检验实验鸡抗体出现阳性的结果表明同时也存在着体液免疫。
