However, measuring p27 in the blood at ages 1 and 6 weeks old by ELISA could be used for discriminating the ALV-J-infected flocks from non-infective flocks having endogenous non-tumorigenic avian leucosis. Because the p27 of the former increases but that of the latter decreases during young ages.

然而應用ALV-J可在1周齡內(nèi)雞群中迅速傳播的特性，感染雞群早期的p27會上升插穴影院，因此檢測1周齡及6周齡雞只血液p27的升高色噜噜噜在线观看网站，可以與無ALV-J感染只含內(nèi)源性病毒的雞群區(qū)別。

To explore the influence of reticuloendotheliosis virus and subgroup J avian leucosis virus infection on chicken cellular immunity,the mitogenic response to ConA of blood and spleen lymphocytes tested and analyzed with 3H-thymidine(3H-TdR) incorporation assay at different intervals after infection or co-infection of single or both viruses.

自1974年分離出網(wǎng)狀內(nèi)皮增生癥病毒[1]和1991年分離出禽白血病病毒J亞群[2]以來，在我國先后分離出不同毒株的REV和ALV-J日韩人成精品视频免费播放在线，并開展了病原學欧美特级黄色片AAAAXXXX、流行病學、致病性和免疫反應以及預防診斷等方面的研究6080午夜久草，揭示出不同的致病性欧美三级视频免费，并且確認它們都可造成感染雞群免疫抑制美女奶头无遮挡网站视频免费观看，成為一些

In order to discuss the interaction of viremia and antibody caused by reticuloendotheliosis and avian leucosis virus of subgroup J, REV, ALV-J and REV+ALV-J were injected to SPF chicken at 2 d separately, then tested the viremia and antibody dynamically for 7 weeks. The results indicated that compared with single infection, the dynamic viremia level of REV and ALV-J wasn't obviously different when coinfected.
