“…Pathogenicity can vary from mild to severe and relative importance of each syndrome varies between countries. It has a world-wide distribution, though some European countries have a long history of BHV-1 control [2]. A number of Member States within the European Union (EU) have either successfully eradicated BHV-1 (Denmark, Finland, Sweden, Austria, the Italian province of Bolzano-Bozen, Switzerland) or implemented an EU-approved compulsory programme (Germany, the Italian province of Trento).…”

BackgroundInfection with bovine herpesvirus-1 (BHV-1) causes a wide range of disease manifestations, including respiratory disease and abortion, with world-wide distribution. The primary objective of the present study was to describe aspects of BHV-1 infection and control on Irish farms, including herd-level seroprevalence (based on pooled sera) and vaccine usage.MethodsThe characteristics of a diagnostic indirect BHV-1 antibody ELISA test when used on serum pools were evaluated using laboratory replicates for use in the seroprevalence study. The output from this indirect ELISA was expressed as a percentage positivity (PP) value. A proposed cut off (PCO) PP was applied in a cross-sectional study of a stratified random sample of 1,175 Irish dairy and beef cattle herds in 2009, using serum pools, to estimate herd seroprevalence. The study was observational, based primarily on the analysis of existing samples, and only aggregated results were reported. For these reasons, ethical approval was not required. Bulk milk samples from a subset of 111 dairy herds were analysed using the same ELISA. Information regarding vaccine usage was determined in a telephone survey.ResultsA PCO PP of 7.88% was determined to give 97.1% sensitivity and 100% specificity relative to the use of the ELISA on individual sera giving maximization of the prevalence independent Youden's index, on receiver operating characteristics analysis of replicate results. The herd-level BHV-1 seroprevalence was 74.9% (95% CI - 69.9%-79.8%), with no significant difference between dairy and beef herds. 95.5% agreement in herd classification was found between bulk milk and serum pools. Only 1.8 percent of farmers used BHV-1 marker vaccine, 80% of which was live while 75% of vaccinated herds were dairy.A significant association was found between herd size (quartiles) and seroprevalence (quartiles).ConclusionsThe results from this study indicate BHV-1 infection is endemic, although BHV-1 vaccines are rarely used, in the cattle population in Ireland.

“…ELISA is commonly used in the detection and control of this disease (Hebert et al, 1985;Ackermann et al, 1990;Beer, 2010). To assist in the diagnosis of this disease in the UK, the Animal Health and Veterinary Laboratories Agency (AHVLA) uses an in-house indirect ELISA (Anderson et al, 2011).…”

“…This allows for serological differentiation between artificial vaccination and cattle that were naturally infected (Van Oirschot, Kaashoek, Maris-Veldhuis, Weerdmeester, and Rijsewijk, 1997). This is a useful method to detect infected animals and eliminate them from the herd to prevent the possibility of reactivation of latent virus (Ackermann et al, 1990;Kaashoek et al, 1995).…”

The study objectives were: 1) to characterise the development of immunocompetence in beef suckler calves from birth to three months of age, and 2) to trace glycoprotein E (gE)-negative bovine herpesvirus type 1 (BoHV-1) antibodies from dam to calf and subsequent vaccination against pneumonia. Thirty multiparous beef suckler, spring-calving cows, consisting of two genotypes were involved; Limousin×Friesian (LF) and Charolais×Limousin (CL). Cows were immunised against the inactivated antigen strain of BoHV-1 (gE- (IBR marker vaccine) at day -84 and received a booster at day -56 relative to the expected calving date (d 0). Calves were immunised at 14 and 42days of age against PI-3 virus, BRSV and Mannheimia (Pasteurella) haemolytica serotype A1 using a commercial vaccine administered subcutaneously. Additionally, calves were immunised against BoHV-1 at 42days of age, using 1 dose of a live commercial vaccine administered intranasally. Blood samples were collected from all calves (n=30) via jugular venipuncture at birth, prior to colostrum feeding (0h), at 12h (h), 24h, 72h and 168h after the initial feeding of colostrum, and at d 7, 14, 28, 42, 56 and 84 post birth. The mean ratio of gE negative antibodies circulating in the blood of LF and CL dams pre-partum scored negative to gE ab (S/N≥0.70). Antibody levels of BoHV-1 (wild type (wt)) peaked at 12h post-birth in calves and declined thereafter, as the maternal antibodies decayed. There was no difference in BoHV-1 and BRSV antibody levels in calves post vaccination.
