Abstract: | Відпрацьовано методику виділення ДНК з цільного молока корів та проведено порівняльні ви пробування щодо ідентифікації вірусу лейкозу у зразках крові та молока великої рогатої худоби ме тодом ПЛР у реальному часі. Отримані результати свідчать про можливість використання молока як альтернативного діагностичного матеріалу. |
Description: | Bovine leukosis virus (BLV) is one of the most wide-spread cancer diseases of agricultural animals. It brings many economic negatives because of animal death, low income of animal products and loss of unique gene pool of high-productive animals. Disease agent is leukosis virus, which belongs to Retrovіrіdae, Deltaretrovіrus. It is RNA-contained cancer virus of type С, it vital cycle consists of necessary stage of integration of DNA-copy (provirus) of virus genome into genome of infected animal. Bovine Leukosis is a serious problem for national cattle breeding in Ukraine for many years. Solution of this problem is possible with timely reliable diagnostics and isolation of infected animals. Nowadays immunological and molecular-genetic approaches are applying in laboratory diagnostic of BLV. Different biological liquids, especially whole blood and serum are used as diagnostic material. At the same time blood sampling is one of significant difficulties of modern analysis methods because of its stressogenic for cows. There is an information in scientific literature about possibility of milk using as alternative source of diagnostic material. We have designed the methodology of bovine whole blood DNA extraction and performed comparative tests for BLV diagnostics in blood and milk samples in this study. Provirus BLV DNA identification was provided by Real-Time PCR. We analyzed totally 10 milk and blood samples from the same animals. BLV infection of animals was previously confirmed by ELISA. Performed analysis confirmed possibility of milk using for Real-Time PCR BLV analysis. But it has some limitations. In condition of relatively low concentration of virus in sample there is a possibility of false negative results. Data obtained has to be further studied for high-effectiveness of amplification of milk extracted DNA. |
