background:
Porcine Parvovirus Infection (PPV) is the most common and important cause of infectious infertility. Porcine parvovirus is a fairly tough virus that multiplies normally in the intestine of the pig without causing clinical signs. It is world-wide in its distribution. If you test for it in your pig herd it is almost certain it will be present unless your herd is less than 100 sows when it might have died out. It is therefore an infection you have to live with and manage. Whereas most viruses do not survive outside the host for any great period of time PPV is unusual in that it can persist outside the pig for many months and it is resistant to most disinfectants. This perhaps explains why it is so widespread and so difficult to remove from the pig environment.

猪细小病毒(Porcine parvovirus,PPV)是引起猪繁殖障碍的重要病毒性传染病。病毒经口、鼻等黏膜感染是其主要感染途径。怀孕母猪感染后可通过胎盘感染引起母猪流产、死胎、木乃伊胎及新生仔猪死亡。因该病流行面广,危害严重,给养猪业带来重大经济损失。PPV基因组编码3种结构蛋白,分别是VP1、VP2、VP3,其中VP2是构成病毒粒子的主要衣壳蛋白,约占病毒衣壳蛋白总量的80%,VP2蛋白携带主要的抗原决定簇,可诱导机体产生中和抗体,VP2对病毒感染、发挥其致病性方面亦起关键作用。因此,PPSLVVP2蛋白在PPV诊断和免疫防治等有着很重要的意义。
