Evaluation of Polymerase Chain Reaction (PCR) Application in Diagnosis of Bovine Leukaemia Virus (BLV) Infection in Naturally Infected Cattle
TL;DR: Findings indicate that PCR is a highly sensitive method and might be successfully used and economically advantageous for different practical applications in detection of BLV infection in naturally infected cattle.

Identification of different BLV provirus isolates by PCR, RFLPA and DNA sequencing.
TL;DR: A phylogenetic tree resulting from the comparison of the sequences of these env fragments demonstrates the relations and differences between and within the subgroups of BLV.

Ahmed Zaghawa,Dagmar Beier,I. H. A. Abd El-Rahim,I. Karim,S. El-ballal,Franz Josef Conraths,Otfried Marquardt +6 more
TL;DR: Since this was the first recorded case of enzootic bovine leukosis in Upper Egypt, strict quarantine measures were adopted and all serologically positive animals in the herd were culled.

Cattle infected with bovine leukaemia virus may not only develop persistent B-cell lymphocytosis but also persistent B-cell lymphopenia.
Jörg Beyer,Bernd Köllner,Jens Peter Teifke,Elke Starick,Dagmar Beier,Ilona Reimann,U. Grunwald,Mario Ziller +7 more
TL;DR: In PL+ cattle the absolute number of B-cells and, therefore, their relative percentage is significantly increased, and it can be assumed that cytotoxic T cells are involved in this B-cell lymphopenia.

Possibilities and limitations for use of the polymerase chain reaction (PCR) in the diagnosis of bovine leukemia virus (BLV) infection in cattle
TL;DR: Comparing the suitability of agargel-immunodiffusion, enzyme-linked immunosorbent assay, ELISA and polymerase chain reaction for diagnosis of BLV-infected cattle found the four PCR variants yielded a similar sensitivity for BLV provirus detection.
