“…Other studies conducted in our country confirm the existence of both viruses, in consistence with our findings, and indicated that they are still circulating among Türkiyes' horse population (Başkaya et al, 1968;Yılmaz et al, 1995;Gür and Yapici, 2008;Ataseven et al, 2010;Turan et al, 2012, Yildirim et al, 2015. Further studies are needed to investigate the prevalence and distribution of EHV-4 in the examined population.…”

“…Past research in our country has also highlighted the occurrence of EHV infections (Başkaya et al, 1968;Yilmaz et al, 1995;Mengi et al, 1996). The EHV-1 and EHV4 infections were presented in the indigenous horse population in the Eastern, North Eastern, Central and Western Anatolia of Türkiye (Gür and Yapici, 2008;Ataseven et al, 2010, Turan et al, 2012Yildirim et al, 2015). In diagnosing EHV-1 and EHV-4 infections in horses, samples are typically taken from fetal organs when nasal discharge, buffy coat, or abortion is observed.…”

“…For example, an outbreak caused by EHV-1 resulted in 52 mare abortions at TJK Izmit pension stud (Yilmaz et al, 1995). There are different studies that report that EHV-1 and EHV-4 infections are observed in Türkiye (Başkaya et al, 1968;Mengi et al, 1996;Gür and Yapici, 2008;Ataseven et al, 2010, Turan et al, 2012Yildirim et al, 2015).…”

The aim of this study was to detect and differentiate equine herpes virus type-1 (EHV-1) and type-4 (EHV-4) by polymerase chain reaction (PCR). The diagnostic sensitivity of the PCR was also examined. For this purpose, suspicious samples obtained from different breeding farms and racehorse hospitals were used. During this study, multiple organ and tissue samples of 26 aborted fetuses were collected and analyzed with PCR. In addition, 98 nasal swab specimens from racehorses aged 2 and above representing the respiratory symptoms of EHV infections were collected and examined by the PCR method. This study started with the optimization of PCR using EHV-1 (89c25p) and EHV-4 (TH20p) DNA, which are reference strains. It was observed that the gB common oligonucleotide primers and species-specific gC primers used in optimization matched the viral DNA specific for target EHV-1 and EHV-4.Finally 7 EHV-1 positives at tissues of aborted fetuses of 26 and 1 EHV-1 and 2 EHV-4 positives at nasal swab samples of 98 has been detected and differentiated by PCR. This was the first PCR study to detect and differentiate EHV-1 and EHV-4 in Turkey. Results of this study reveal the presence of EHV-1 and EHV-4 in Turkey. Especially the presence of EHV-4 virus has been shown for the first time. As a result of the study, detection of EHV-1 and EHV-4 genomic DNAs by PCR indicated that both viruses circulate between racehorse population.In conclusion, we agreed that the PCR is a sensitive, economical and time-saving method in detecting and differentiating EHV-1 and EHV-4 infections. Key words:EHV-1, EHV-4, infection, Polymerase Chain Reaction (PCR)

Background Equine herpesvirus (EHV) may cause respiratory, reproductive and neurological diseases in equine animals, including donkeys, of which EHV type 1 (EHV-1) and EHV-4 are the main pathogens. To investigate the prevalence of EHV in donkeys in the Liaocheng area (an important donkey breeding areas in China), and the effect of EHV infection on immunity and antioxidant capacity in donkeys.the epidemiological investigation of EHV was proceed by detected the EHV-1 and EHV-4 in 230 donkey serum collected from 27 large-scale donkey farms, and the serum samples of 10 normal (without EHV-infected) and 10 EHV-infected donkeys with similar age were used to detect the immune and antioxidant related indexs. Result The results showed that 62.96% (17/27) of farms were positive for EHV, and the total positive rate of EHV was 12.61% (29/230) with 7.82% (18/230) for EHV-1, 9.57% (22/230) for EHV-4 .Conclusion: Moreover, The differences of EHV infection among different regions in Liaocheng were not significant (P > 0.05), but the highest positive rate was found in Dong'e County (21.28%,10/47). The highest positive rate of EHV-1/4 was 21.18% (18/85) in adult donkeys aged 1–4 years, which was significantly different from other age groups (P < 0.05). The difference in seasons was not significant (P > 0.05), but the highest positive rate was 19.61% (10/51) in winter. Furthermore, EHV infection increased the levels of the immune related indexs IgA, IgG, IgM and IL-6, inhibited the activities of SOD and T-AOC, and improve the activities of GSH-PX and content of MDA. Consclusions: These results indicated that EHV infection is prevalent in large-scale donkey farms in the Liaocheng area, and EHV infection could interfere immune, cause inflammation and oxidative stress, which facilitate early warning of EHV epidemic risk.
