PEREZ-CASCALES, Esdenka et al. Presence of Oligoryzomys microtis (Rodentia) in wild habitats in Bolivia. Salud(i)Ciencia [online]. 2023, vol.25, n.6, pp.327-332.  Epub Nov 05, 2023. ISSN 1667-8682.  http://dx.doi.org/10.21840/siic/172133.

Rodents are very important organisms within ecosystems; however, some species are considered pests because they consume and damage crops and because they are vectors, hosts, or reservoirs in the transmission of emerging infectious diseases. Rodents in Bolivia are represented by 148 species, Oligoryzomys microtis (Allen, 1916) being a species of public health importance because it is considered a potential natural reservoir of the Chapare virus, which causes Chapare Hemorrhagic Fever, and it is a deadly disease for humans. Its impact on public health is still unknown. The present study consisted of recording the presence of the species O. microtis through the use of Sherman-type live capture traps for small mammals arranged in linear transects in the wild and intervened habitats of the Samuzabety community, where the Chapare virus was detected for the first time, this community is located in the Chapare Province of the department of Cochabamba, Bolivia. The species recorded were the rodents Oligoryzomys microtis (morphotype matogrossae), Proechimys brevicauda, Neacomys vargasllosai, Hylaeamys perenensis, and the marsupial Metachiurus nudicaudatus. The presence of the species O. microtis (morphotype matogrossae) in the community of Samuzabety is confirmed. This species is associated with forest habitats with nearby and surrounding crops. The species O. microtis has epidemiological relevance, as it is the natural reservoir of the Río Mamoré Hantavirus and is currently considered a potential reservoir of the Chapare virus and other Arenaviruses.
