[Arbovirus serological survey among marine and non-marine birds of Brittany].
Sera from 215 seabirds (mainly gulls) and 74 landbirds (mainly starlings) from Brittany were studied by hemagglutination inhibition and complement fixation tests for antibody against 9 arboviruses among them 8 were previously isolated from ticks associated with seabirds. Among seabirds, 145 or 65% were found positive for flaviviruses and nairoviruses of the Hughes serogroup. Unexpected frequency of HI positive reactions for Tyuleniy virus indicate the possible circulation of this virus among seabirds colonies of Brittany in addition to the recently isolated Meaban flavivirus. Among landbirds, only one positive HI reaction for Tyuleniy virus was detected in a house sparrow (Passer domesticus) and it seems that landbirds may not play an important role in the dissemination of these arboviruses to man and to domestic animals.
