[Mixed sero-epidemiologic study of arbovirus-arenavirus in the small mammals of Tunisia].

Blood samples of 156 small mammals caught in Tunisia in 1976 and 1977 were examined for the presence of antibodies to some arboviruses and arena-viruses. Haemagglutination-inhibiting antibodies against West Nile virus were detected in 19.8 0/0 of examined sera, mainly from Mus sp., Rattus rattus, Eliomys tunetae in the northern part of the country and from Ctenodactylus gundi and Pipistrellus kuhli in the south. In addition, antibodies against Uukuniemi and Bhanja were found in 3.2 0/0 and 4.5 0/0 respectively of the same sera.
