*LCMV, lymphocytic choriomeningitis virus; CSF, cerebrospinal fluid, NT, not tested.
†An animal was considered infected with LCMV if virus was isolated either in Vero cells or results of at least 2 of 3 PCRs were positive.
‡After diagnostic tests were performed from CSF, no material was available to attempt virus isolation.
§Virus strain characterized by full-length genome sequencing (GenBank accession nos. DQ286931 and DQ286932 for S and L RNA, respectively).
