Resumen:
The aim of this study was molecular identification of bovine leukemia
virus and possible co-infection with bovine respiratory disease complex
(BRDC) viral agents in Mexican dairy herds. We collected 533 blood
samples from cattle vaccinated against the BRDC virus in 9 states across
Mexico. Peripheral blood leukocytes were removed and genetic material
was extracted to detect bovine leukemia virus (BLV), bovine herpesvirus
1 (BoHV-1), bovine viral diarrhea virus (BVDV), bovine parainfluenza
virus 3 (BPIV- 3), and bovine respiratory syncytial virus ( BRSV)
infection using polymerase chain reaction. We identified high BLV
infection rates in 270 cattle (50.65%). One hundred and thirty-three
cows (24.95%) tested positive for BoHV-1, of which 65 samples were
positive for both viruses (BoHV-1 and BLV) and 68 were only positive for
BoHV-1. Only 4 samples tested positive for BPIV-3 and no sample was
positive for BVDV or BRSV. Relative risk and odds ratio analyses did not
identify that the presence of BLV infection favors BoHV-1 co-infection
in vaccinated herds.
