Popis:	Alcelaphine herpesvirus 1 (AlHV-1) is a gammaherpesvirus carried asymptomatically by wildebeests (Connochaetes sp.) in sub-Saharan Africa. Although asymptomatic in wildebeest, AlHV-1 infection in a number of other ruminant species causes a severe and fatal lymphoproliferative disease named wildebeest-derived malignant catarrhal fever (WD-MCF). Several endangered species of captive ruminants are highly susceptible to developing WD-MCF if infected by AlHV-1, which is a critical concern in zoos, game reserves and wildlife parks where wildebeests are also kept in captivity. Here, we investigated the seroprevalence of AlHV-1 in 52 captive wildebeests randomly sampled from five different zoos in France. We found 46% (24/52) seropositive animals and detected AlHV-1 DNA in one of them, demonstrating that AlHV-1 infection is present in captive wildebeests in France. In an interesting manner, the repartition of seropositive wildebeests was not homogenous between zoos with 100% (20/20) of seronegative animals in three parks. These results further highlight the importance of considering WD-MCF as a threat for clinically susceptible species and encourage for testing AlHV-1 infection in captive wildebeests as a management control strategy.
