In this study, serum samples of 877 cattle from 6 dairy herds located in three different regions of Turkey were tested for presence of antibodies against BHV4 using commercial ELISA. Out of herds, three herds (group I) included cattle with reproductive disorders as postpartum metritis, abortus, repeat breeders, whereas the 3 other herds without reported reproductive pathologies constituted the group II. All the selected herds had seropositive animals and BHV4 seroprevalences were ranged between 33.1% (herd III) to 69.5% (herd II) in the 6 dairy herds and the overall BHV4 seropositivity was 54.3%. Additionally, the BHV4 seroprevalence was significantly higher in the group I (56.8%) than in the group II (44.9%) (p < 0.05) and a significant interaction between reproductive pathologies and BHV4 seropositivity was evidenced in the group I (OR: 1.615, p < 0.05). Moreover, BHV4 infection was significantly correlated with the age of animals in the overall population (p < 0.01), as well in the group I (p < 0.01) and in the group II (p < 0.05), the older animals being more frequently infected than the youngest animals (< 2 year old). This is the first report showing the presence of BHV4 infection in cattle in Turkey, and these results suggest a possible role for BHV4 alone or in association with other viral or bacterial agents in the aetiology of reproductive disorders in cattle.
