Abortions,
fetal mummification, calf anomalies, and infertility problems are the majority
of reproductive problems in cattle. Viruses play a
significant role in the cause of these cases. In cattle, these agents are known
as primary abortion agents and the most common of these agents are Bovine Viral
Diarrhea Virus (BVDV), Bovine Herpes Virus Type 1 (BoHV-1), and Bovine Herpes
Virus Type 4 (BoHV-4) infections. The objective of this research is to
determine the possible role of BVDV, BoHV-1, and BoHV-4 as viral abortion
agents in cattle housed in the Van district. For this, a total of 115 animal specimens
(blood, serum, vaginal swab, vaginal fluid discharge, nasal swab, and abortion
material) from 100 abortion, early embryonic deaths, and fertility problems
cases in cattle over the age of 2-5 years old were collected. All samples for
detection of BVDV, BoHV-1 and BoHV-4 genomes were tested by the Polymerase
Chain Reaction (PCR) technique using specific primers encoding Panpesti 5'-UTR,
Glycoprotein C (gC) and Glycoprotein B (gB) genes, respectively. Result
out of the samples tested, %41.73 were positive for BVDV and all samples were
negative for BoHV-1 and BoHV-4. In conclusion, the presence of BVDV in cattle
in the Van region and its role in the occurrence of abortion cases was emphasized
for the first time; consideration of viral abortions and determining the
etiology of abortion cases and genital system problems needs to focus on the
detection of persistent infected (PI) animals and the most effective way of
vaccination of susceptible populations for prevention and control of infection.
