| Abstract: | Canine herpesvirus (CHV1) is found in dogs all over the world and may spread by oronasal or sexual contact. We developed an enzyme-linked immunosorbent assay (ELISA) for the detection of antibodies against CHV1 in dogs. The antigen used for this ELISA was prepared by purifying CHV1 virions from the medium of infected A72 cells. To investigate the prevalence of CHV1 in The Netherlands, a panel of 145 sera of dogs boarding at a kennel in Lelystad, The Netherlands, was screened using this ELISA. The dogs originated from all parts of The Netherlands and represented many different breeds. The sera were collected both at the start and at the end of the boarding period. Of the 145 paired sera 61 (42.1%) were positive, 79 (54.5%) were negative and 5 (3.4%) could not be attributed to either group. None of the negative dogs became seropositive during the boarding period, which lasted normally two to three weeks. We also tested 79 individual sera taken from dogs at various other places in The Netherlands and found that 27 (34.2%) were positive. Hence, in total 224 dog sera, collected from April 1997 to March 1998, were tested and 88 (39.3%) were found positive. We conclude that the prevalence of CHV1 seropositive dogs in The Netherlands in this period was about 40%, and that boarding at a dogs kennel did not contribute to the spread of CHV1. In addition, CHV1 has been isolated from two clinical cases of fatal haemorrhagic disease in The Netherlands. |
