Small mammals from Côte d'Ivoire tested by pan-Old World arenavirus RT-PCR, Lassa virus-specific RT-PCR, and Old World arenavirus immunofluorescence assaya.

aCollections with RT-PCR-positive samples as well as the respective animals are indicated in boldface.bTaxonomic classification is based on morphological field data, if not otherwise indicated.cThe number of positive animals is given in parentheses in the order: RT-PCR-positive; immunofluorescence assay-positive. If none of the animals was positive in either test, only the number of tested animals is indicated. Sampling sites: Ah, Ahouakro; Ba, Bakro; Bl, Blodi; Gb, Gbagroube; Ko, Kotokossou; La, Lamto; Me, Menekre; Sa, Sanguiebo; To, Touzoukro.dSamples CIV839, CIV843, and CIV1227 tested positive in pan-Old World arenavirus (OWA) large (L) and glycoprotein precursor (GPC) gene RT-PCRs.eThe mitochondrial cytochrome B gene of a representative subset of 73 animals, including the antibody-positive animals, from Ahouakro, Blodi, Gbagroube, Kotokossou, Menekre, and Sanguiebo was sequenced. All animals sequenced were genetically confirmed to be Mastomys natalensis.fAnimals were classified by sequencing the cytochrome B gene. Cytogenetic, molecular, and morphometrical analysis has been published for a subset [47].gSamples CIV608, CIV674, and CIV1290 tested positive in pan-OWA L and GPC gene RT-PCRs. Seven further animals were positive for anti-OWA IgG antibodies.
