| Abstract: | From post-mortem material (liver and lung) and leucocytes of four (3.6%) out of 112 examined harbour seals during the seal epizootic in 1988 six cytopathogenic viral isolates were obtained which were provisionally classified as herpes-like viruses. Results of physico-chemical and electron microscopic investigations suggested their relationship to the herpesvirus family. Serological examinations were carried out with sera from wildlife as well as captive animals using herpesvirus isolates from four different seals. The neutralization tests revealed as only moderate distribution of seropositive reagents up to 53% of the wildlife seal population. Amongst the seals in the orphanage of Norddeich a very small number of seropositive animals was found. The results obtained indicated a minor role of herpesviruses as primary cause of seal mortality in the North Sea during the 1988 season. |
