Of tumor diseases in the global animal husbandry industry, greatest danger is bovine leukemia. Since last century, this neoplastic disease has remained relevant for veterinary medicine and, addition, more and questions arise concerning potential threat of Bovine leukemia virus (BLV) humans. The problem being discussed (G.Yu. Kosovskiy et al., 2016) which additionally stimulates both fundamental...

Abstract. The purpose of the research Was to study genetic diversity bovine leukemia virus isolates obtained in Belgorod Region using restriction fragment length polymorphism method (RFLP). Scientific novelty. Bovine leukosis is one most common chronic infectious diseases cattle many countries world, which causes significant economic losses livestock industry. typing (BLV), its structure, evalu...

It is shown that Boltzmann's methods from statistical physics can be applied to a much wider range of systems, and in a variety of disciplines, than has been commonly recognized. A similar argument can be applied to the ecological models of Lotka and Volterra. Furthermore, it is shown that the two methodologies can be applied in combination to generate the Boltzmann, Lotka and Volterra (BLV) mo...

Experimental bovine immunodeficiency-like virus (BIV)-infection and mixed infection of BIV and bovine leukemia virus (BLV) were performed on sheep. BIV proviral DNA and anti-BIV antibodies were persistently detected in all BIV-inoculated sheep. A slight increase in lymphocyte counts was observed in BIV-infected sheep, but the percentages of CD4+ and CD8+ cells in sheep peripheral blood mononucl...

A cohort study was conducted to evaluate the risk of bovine leukemia virus (BLV) transmission to uninfected cattle by adjacent infected cattle in 6 dairy farms. Animals were initially tested in 2010-2011 using a commercial ELISA kit. Uninfected cattle were repeatedly tested every 4 to 6 months until fall of 2012. The Cox proportional hazard model with frailty showed that uninfected cattle neigh...
