Background

Avian leukemia is a collective term for various neoplastic diseases of the birds caused by viruses of the avian C-type retrovirus group, as well as for infectious diseases and parasitic diseases. Mainly lymphoblastic leukemia, and secondly erythroblastic leukemia and myeloblastic leukemia. In addition, it can cause myeloma, connective tissue tumor, epithelial tumor, endothelial tumor, etc. Most tumors invade the hematopoietic system, and a few invade other tissues such as egg drop, immunosuppression, etc.

Because the transmission mode of the avian leukosis is mostly vertical transmission, the treatment cost of the disease is higher in the current medicine, in order to avoid the transmission of the virus, the breeding poultry is generally detected, the positive poultry is eliminated, the population is optimized, and the screening of the virus is realized. When detecting antigens, the conventional poultry virus antigen detection card needs to be inserted into the vagina of poultry for sampling when detecting the vagina swab, and then the cotton swab is put into the extracting solution and dripped on the detection card after sampling is finished, and whether the poultry has poultry leukemia can be judged by observing the number of the cross bars on the detection card. To this end, we propose a poultry virus antigen detection card.
