| Abstract: | Bovine lymphotropic herpesvirus (BLHV) was detected for the first time in the UK in December 2005 in a dairy herd suffering from chronic, non-responsive post-partum metritis (NPPM). A small-scale investigation was undertaken in order to determine whether this was an isolated case. Samples of vaginal exudates or vaginal swabs were collected from cows in 13 UK dairy herds with a history of post-partum metritis that had not responded to standard treatment regimes for this condition. Cows in 9/13 herds and 1/13 herds were positive for BLHV and bovine herpesvirus-4, respectively, by pan-herpesvirus polymerase chain reaction. No consistent pattern of infectious agents or nutritional/metabolic factors commonly associated with post-partum metritis was observed at the times of sampling. The detection of BLHV in association with NPPM indicates that further work is warranted to determine the impact this virus has on cattle health. |
