Abstract
Neuroinfectious diseases in cattle, which result in significant economic losses
and pose a serious threat to animal health, often go undiagnosed due to the
challenge of identifying their underlying cause. In this study, a total of 180
brain samples from cattle with neurological symptoms were collected from various
provinces in Türkiye during 2021-2022. Viral nucleic acids were extracted,
followed by PCR and RT-PCR assays targeting specific gene regions of BoHV-1,
BoHV-5, OvHV-2, and BoAstV. BoHV-1 was detected in 7.22% (13/180) of the
samples, BoHV-5 in 5.00% (9/180), and OvHV-2 in 0.55% (1/180). BoAstV, however,
was not detected in any of the samples. Analysis of the gB gene region sequences
revealed a high nucleotide identity (100%) between BoHV-1 strains from America,
Israel, Sweden, and Italy, and BoHV-5 strains (S9 and S24) from Brazil. The
OvHV-2 strain obtained from this study clustered within the OvHV-2.1 cluster
along with some Asian strains (Iraq, Pakistan, Mongolia, India, Turkey). Studies
focused on neuroinfectious diseases in cattle, especially those related to
BoAstV and BoHV-5, are relatively scarce. This study represents one of the first
investigations into the majority of neuroinfectious viruses in Turkish cattle,
with the identification of BoHV-5 being reported for the first time here. It is
anticipated that the data obtained will significantly contribute to our
understanding of the pathogenesis and molecular epidemiology of these studied
viruses.
