摘要: To investigate the effects of co-infections subgroup J avian leukosis virus (ALV-J) and Eimeria tenella on pathogenesis in specific-pathogen-free (SPF) white leghorn chickens, groups chickens were infected with ALV-J strain NX0101 at one day age or E. 14 days both. The control group was left uninfected mock-inoculated phosphate buffer saline (PBS). Mortality rates, body weights, cecal lesions, viremia each evaluated. Immune status evaluated by measuring several parameters: immune organ weight/body weight index, specific humoral responses to inactivated NDV vaccine inoculated tenella, proportions blood CD3+CD4+ CD3+CD8α+ lymphocytes transcriptional levels cytokines tonsils. results show that induced a higher mortality rate lower SPF compared single-pathogen infection. In co-infected accelerated disease symptoms extended viremia. Thymus atrophy, decrease response pathogens vaccine, modifications lymphocyte sub-populations cytokine disorders found pathogen alone controls. We underline synergy between increasing chickens.
