To demonstrate experimentally the generation of velogenic NDV from a nonpathogenic waterfowl isolate, we passaged an avirulent goose isolate in chickens.

为了通过实验证明从水禽中分离的非致病型NDV可以转变为速发型病毒，我们通过在鸡体内传播鹅源性无毒力株，经气囊接种连续传代 9次，随后再在鸡脑内传代 5次。

Methods Peritoneal macrophages of guinea pigs were infected in vitro by three different Leptospira strains, the virulent Leptospira interrogans serovar Lai type strain Lai, the avirulent L. interrogans serovar Lai type strain IPAV, and the nonpathogenic L. biflexa serovar Patoc type strain PatocⅠ, respectively, and heat inactivated Staphylococcus epidermidis was added 0.5, 1.5, 3 and 6 h after infection and incubated for 30 min. The effect of Leptospira on the phagocytosis of macrophage was evaluated by the inactivated Staphylococcus epidermidis phagocytosis rate and phagocytosis index. Phagocytosis and ultrastructure of peritoneal macrophages were observed by transmission electron microscopy 3 h after infection, and changes of cytoskeleton of the macrophages were observed by laser scanning confocal microscopy.

用三种不同毒力的钩体（致病性问号钩端螺旋体赖型有毒株Lai株、赖型无毒株IPAV株以及非致病性双曲钩端螺旋体Patoc型PatocⅠ株）分别感染体外培养的豚鼠腹腔巨噬细胞，并分别于感染后0.5、1.5、3和6 h加入热灭活表皮葡萄球菌孵育30 min，通过计算巨噬细胞对灭活表皮葡萄球菌的吞噬率和吞噬指数，检测钩体对巨噬细胞吞噬功能的影响；感染后3 h透射电镜观察巨噬细胞对钩体的吞噬、降解和细胞超微结构的变化；用激光共聚焦显微镜观察细胞对钩体的吞噬和巨噬细胞细胞骨架的变化。

The difference of expressed proteins between Lai strain and its avirulent derivative were also studied.

此外，我们还研究了赖株及其无毒株的蛋白表达的差异，以期发现新的、重要的毒力因子。
