  1. Using PCR for early diagnosis of bovine leukemia virus infection in some native cattle.

    Genetics and Molecular Research 10(4):2658 (2011) PMID 22057961

    We obtained 42 positive and 15 doubtful results in the first PCR. The second PCR was very effective in increasing BLV test reliability data to support detection of BLV....
  2. Increased MHC class II and CD25 expression on lymphocytes in the absence of persistent lymphocytosis in cattle experimentally infected with ...

    Veterinary Immunology and Immunopathology 64(3):235 (1998) PMID 9730219

    We recently observed that a group of cattle experimentally infected with bovine leukemia virus (BLV) had enhanced antibody responses to recall antigens. None of the cattle in this group were classified as persistently lymphocytotic, but they did have significantly increased numbers of circulating T...
  3. Intra-cluster correlation coefficients of 20 infections calculated from the results of cluster-sample surveys.

    Preventive Veterinary Medicine 31(1-2):147 (1997) PMID 9234433

  4. Bovine immunodeficiency virus and bovine leukemia virus and their mixed infection in Iranian Holstein cattle.

    The Journal of Infection in Developing Countries 4(9):576 (2010) PMID 21045371

  5. Ovine MHC class II DRB1 alleles associated with resistance or susceptibility to development of bovine leukemia virus-induced ovine lymphoma.

    Cancer Research 59(4):975 (1999) PMID 10029093

    We investigated the association between polymorphism of ovine leukocyte antigen (OLA)-DRB1 gene and tumor development after infection of sheep with BLV. We infected 28 sheep with BLV and cloned exon 2 of the OLA-DRB1 gene from asymptomatic animals and from animals with lymphoma Sequence analysis rev...
  6. Development of a syncytia inhibition assay for the detection of antibodies to bovine leukemia virus in naturally infected cattle; comparison...

    Journal of Virological Methods 70(2):177 (1998) PMID 9562411

    A syncytia inhibition assay (SIA) for the detection of antibodies to bovine leukemia virus is described. This test involves specific antibody-mediated inhibition of BLV-induced cytopathic effects in an indicator cell line. A total of 300 sera were screened commercially by agar gel immunodiffusion (A...
  7. Short-termed expression of interleukin-12 during experimental BLV infection may direct disease progression to persistent lymphocytosis.

    Veterinary Immunology and Immunopathology 64(3):207 (1998) PMID 9730217

    In this study an attempt was made to elucidate cellular response cytokine expression upon experimental bovine leukemia virus (BLV) infection in cattle. Progression of infection was monitored by BLV gp51 mRNA expression or DNA amplification by RT-PCR or PCR, respectively, to detect provirus infected...
  8. Pathobiology of bovine leukemia virus.

    Veterinary Research 25(6):521 (1994) PMID 7889034

    Bovine leukemia virus (BLV) is a retrovirus similar to the human T-cell leukemia virus (HTLV). Most BLV infected animals (70%) develop a B-cell lymphoproliferative syndrome with altered productive traits and 1 to 5% die with B-cell lymphosarcomas. Although BLV infection is world-wide, western Europe...
  9. Evidence for bovine immunodeficiency virus infection in cattle in Zambia.

    Japanese Journal of Veterinary Research 52(1):3 (2004) PMID 15253302

    We report herein on the first evidence for the presence of bovine immunodeficiency virus (BIV) in Zambia. Serological surveillance of BIV and bovine leukemia virus (BLV) was conducted in traditional cattle herds in Zambia. Out of a total of 262 sera analyzed, 11.4% were found positive for anti-BIV p...
  10. Eosinophils in lymph nodes of cows infected by bovine leukaemia virus.

    Acta Veterinaria Hungarica 43(1):145 (1995) PMID 7625286

    Prescapular lymph nodes from 109 animals positive to bovine leukaemia virus (BLV) were evaluated in this study. Lymph nodes of 81 animals (74.3%) showed an increased number of eosinophils (Eo) in a variety of pathological reactions. Eo counts in T-zonal hyperplasia (47 cases, 43.1%) and mixed hyperp...
