Serological Evidence of Lassa Virus Exposure in Non-Mastomys Small Mammals Within a Hyperendemic Region of North-Central Nigeria: A Pilot Study [PDF]

Viruses
Lassa fever (LF), a severe hemorrhagic disease endemic to West Africa, is primarily transmitted by rodents of the genus Mastomys, particularly Mastomys natalensis, which serve as the main reservoirs of Lassa virus (LASV).

Mastomys natalensis and Mastomys coucha: identification, habitat preferences and population genetics

, 2010
M.Sc. Two species of multimammate mice occur in South Africa, namely Mastomys natalensis and M. coucha. These species, both reservoirs for different and equally important disease pathogens, are morphologically identical with variations described in chromosome number, sperm morphology, pheromones, ultrasound and allozyme and isozyme markers.

Impact of seasonal change on virus-rodent dynamics in Nigeria’s Edo-Ondo hotspot for Lassa fever [PDF]

Current Research in Parasitology and Vector-Borne Diseases
The zoonotic Lassa virus (LASV) is naturally maintained in rodents but commonly virulent in humans, killing thousands across West Africa annually. Human cases of Lassa fever surge during the dry season.

Impact of fertility versus mortality control on the demographics of Mastomys natalensis in maize fields. [PDF]

Integr Zool, 2022
The multimammate mouse, Mastomys natalensis, is the most common rodent pest species in sub-Saharan Africa. Currently, rodenticides are the preferred method used to reduce the population of rodent pests, but this method poses direct and indirect risks to ...

Land use gradients drive spatial variation in Lassa fever host communities in the Eastern Province of Sierra Leone. [PDF]

J Anim Ecol
As West Africa urbanises, the risk of Lassa fever may paradoxically decrease. We found the invasive house mouse, a dominant urban species, outcompetes and displaces the primary Lassa virus host. Considering these species interactions is critical for accurately predicting future zoonotic disease patterns.

Comparison of rodent community between natural and modified habitats in Kafta-Sheraro National Park and its adjoining villages, Ethiopia: implication for conservation

Journal of Basic and Applied Zoology, 2019
Background Distribution and diversity of rodents vary across habitats due to different environmental factors. An ecological comparative study on diversity and abundance of rodents was conducted in Kafta-Sheraro National Park and its nearby villages from ...

No measurable adverse effects of Lassa, Morogoro and Gairo arenaviruses on their rodent reservoir host in natural conditions

Parasites & Vectors, 2017
Background In order to optimize net transmission success, parasites are hypothesized to evolve towards causing minimal damage to their reservoir host while obtaining high shedding rates. For many parasite species however this paradigm has not been tested,

Partitioning Social and Spatial Drivers of Infection Risk. [PDF]

Ecol Evol
Contact rates drive disease spread, yet are often oversimplified as uniform across individuals. Using data on Mastomys natalensis, we show that exposure to Morogoro virus is linked to spatial overlap with infected conspecifics, but not overall overlap, and that direct contact occurs with only a few individuals despite broad home range overlap ...

Detection of Lassa virus in wild rodent feces: Implications for Lassa fever burden within households in the endemic region of Faranah, Guinea

One Health, 2021
Lassa arenavirus (LASV) is the cause of Lassa Fever in humans in West Africa. The multimammate mouse (Mastomys natalensis) is a reservoir host of LASV and the primary source of human infections.

Widespread arenavirus occurrence and seroprevalence in small mammals, Nigeria

Parasites & Vectors, 2018
Background Lassa fever, killing thousands of people annually, is the most reported viral zoonotic disease in Nigeria. Recently, different rodent species carrying diverse lineages of the Lassa virus (LASV) in addition to a novel Mobala-like genetic ...
