“…In Poland, 1541 serum samples from Holstein cattle from 23 herds were analyzed using ELISA method. The average BIV prevalence was 4.9% in individual cattle while the percentage of herds harboring at least one seropositive animal, was 82.6% [29].…”

Prevalence of Bovine Immunodeficiency Virus Infection in Buffaloes in East Azerbaijan, Northwestern Iran

Bovine immunodeficiency virus (BIV) has a worldwide distribution, but its prevalence in different regions of Iran is unknown. In this study, for the first time, the presence of BIV infections is detected by using the PCR method in Iranian water buffalo in East Azerbaijan. For this matter, blood samples were taken from 83 randomly selected buffaloes slaughtered in Tabriz industrial slaughterhouse from June to October 2012. All of the animals were clinically examined before sampling. Viral Gene-spin™ Viral DNA/RNA Extraction Kit was used to extract the DNA, and PCR was performed on the extracted DNA using oligonucleotiode primers specific for the gag gene region of the BIV virus. The prevalence of BIV in buffaloes was 2.4% (2 of 83), which is less than the prevalence of BIV in Pakistan (10.3%) and India (19%). The low prevalence observed in this study may be due to our small sample size.

“…The highest prevalence was noticed in Costa Rica (16) and the United States (28), while it was moderate in Japan (34), Pakistan (20) and Korea (6). Some reports also confirm BIV infections of cows in European countries: the Netherlands (17), Germany (22) and Poland (27) have been affected, but with lower seroprevalence. The most recent report on the occurrence of BIV in cattle comes from Mexico, showing a 28.94% prevalence (15).…”

Introduction Bovine immunodeficiency virus (BIV) is found worldwide in cattle under natural conditions. However, the effect of BIV infection on immune functions has not been fully characterised. Material and Methods Transcriptome analysis of BoMac cells after in vitro infection with BIV was performed using BLOPlus bovine microarrays. Genes identified as differentially expressed were subjected to functional analysis with the Ingenuity Pathway Analysis software (IPA). Results Out of 1,743 genes with altered expression, 1,315 were mapped as unique molecules. In total, 718 genes were identified as upregulated and 597 genes as downregulated. Differentially expressed genes were involved in 16 pathways related to immune response. The most enriched canonical pathway was leukocyte extravasation signalling. Interleukin-15 (IL-15) production was indicated as the most activated pathway and the 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 4 (PFKFB4) signalling pathway was the most inhibited one. In addition, the study showed that the inflammatory response was decreased during BIV infection. Conclusion This is the first report to describe the microarray analysis of changes in gene expression upon BIV infection of bovine macrophages. Our data indicated how BIV influences the expression of genes and signalling pathways engaged in the immune response.

“…The main pathologies associated with BIV are lymphadenopathy, lymphocytosis, non‐suppurative meningoencephalitis, progressive wasting, low milk production, low blastogenic lymphocytic response, bovine paraplegic syndrome and secondary infections derived from immunosuppression (Carpenter et al, ; Snider et al, ; Suarez, VanDerMaaten, Wood, & Whetstone, ; Van Der Maaten, Boothe, & Seger, ). There is controversy about the association or predisposition that may exist between the BIV and the bovine leukaemia virus (BLV; Brujeni, Poorbazargani, Nadin‐Davis, Tolooie, & Barjesteh, ; González et al, ; Rola, Kozaczynska, Pluta, & Kuzmak, ; Rola‐Łuszczak, Kozaczyńska, & Kuźmak, ). Recent findings (De Oliveira et al, ) in BIV sequences found within multicentric B‐cell lymphomas from BLV‐negative cows suggest their oncogenic potential.…”

This study set out to identify the presence of bovine immunodeficiency virus (BIV) in animals geographically located in Mexico. BIV was first discovered in the United States in a dairy cow with persistent lymphocytosis, lymphoid hyperplasia and lymphocytic encephalitis. Many studies indicate that BIV infection is globally distributed, but its presence in Mexico remains unknown. We collected 1,168 heparinized blood samples from cattle in ten states across the Mexican Republic, then separated plasma using centrifugation and tested for antibodies against BIV. We used an indirect ELISA based on the use of a synthetic peptide derived from transmembrane glycoprotein (gp45/TM). In order to identify the viral genome, we designed a synthetic gene as a PCR control, as well as a pair of oligonucleotides for amplifying a 519 bp product of the env gene which encodes the surface protein. Positive amplicons were purified and subjected to nucleotide sequencing. A total of 189 (28.94%) tested plasma samples suggest the presence of specific anti‐BIV antibodies in all states studied except for Chiapas. Additionally, PCR results identified six positive cows in the states of Puebla and Coahuila. BIV in these cows was confirmed via nucleotide sequencing and in silico analysis of these samples. This is the first report of the presence of BIV in Mexican cattle.
