| serological studies of mucosal disease virus in england and wales. | a survey of the cattle population in england and wales showed that about 62 per cent of animals had neutralising (sn) antibody to bvd-md virus in their serum. fewer seropositive individuals were detected by immunodiffusion (53 per cent), and complement fixation (cf) tests (34 per cent). the prevalence of antibody was not affected by herd size, but some variation was found between various regions of the country, and the proportion of animals seropositive rose markedly with age. the immunodiffusio ... | 1978 | 203990 |
| severe disease in adult dairy cattle in three uk dairy herds associated with bvd virus infection. | during 1993 outbreaks of diarrhoea in adult dairy cows in three geographically unrelated herds were found to be caused by bovine viral diarrhoea virus (bvdv). the affected animals showed signs of acute watery diarrhoea, agalactia and pyrexia (39.4 to 42 degrees c). ulceration of the buccal mucosa, a mucoid nasal discharge and stiffness were inconsistent signs. the disease spread rapidly in each case. the diagnosis was confirmed by the isolation of non-cytopathic bvdv from blood and tissues and b ... | 1994 | 8059512 |

| prevalence of antibodies to bovine virus diarrhoea virus and other viruses in bulk tank milk in england and wales. | bulk tank milk samples from 1070 dairy herds in england and wales were tested by elisa for antibodies to bovine virus diarrhoea virus (bvdv). a subset of 341 herds was tested by elisa for antibodies to bovine herpesvirus 1 (bhv-1), bovine respiratory syncytial virus (brsv) and bovine coronavirus (bcv). none of the herds had less than 40 dairy cows and none had been vaccinated against bvdv. the prevalence of bvdv antibody-positive herds in the national population was estimated at 95 per cent and ... | 1998 | 9586130 |
| long-term viral serology of semi-free-living and captive ungulates. | between 1973 and 1994, blood samples were collected at whipsnade wild animal park (uk) from three ungulate species kept in enclosures, including 28 european bison (bison bonasus), 37 scimitar-horned oryx (oryx dammah), and 49 père david's deer (elaphurus davidianus), and also from 144 semi-free-living chinese water deer (hydropotes inermis). these samples were tested for the presence of antibodies against three bovine viral diarrhea virus (bvdv)-like strains, three alpha-herpesvirus strains, enz ... | 1998 | 9732031 |
