O Mastomys natalensis como modelo alternativo nos estudos da esquistossomose mansoni experimental

Revista do Instituto de Medicina Tropical de São Paulo, 1984
Foram estudados aspectos da infecção e da imunidade experimentais em um roedor — o Mastomys natalensis — inoculado com a cepa LE (Belo Horizonte) do Schistosoma mansoni, comparando os resultados com os do camundongo albino, animal tido como melhor modelo

Sympatric Occurrence of 3 Arenaviruses, Tanzania

Emerging Infectious Diseases, 2010
To determine the specificity of Morogoro virus for its reservoir host, we studied its host range and genetic diversity in Tanzania. We found that 2 rodent species other than Mastomys natalensis mice carry arenaviruses. Analysis of 340 nt of the viral RNA

Rodent control to fight Lassa fever: Evaluation and lessons learned from a 4-year study in Upper Guinea. [PDF]

PLoS Neglected Tropical Diseases, 2018
Lassa fever is a viral haemorrhagic fever caused by an arenavirus. The disease is endemic in West African countries, including Guinea. The rodents Mastomys natalensis and Mastomys erythroleucus have been identified as Lassa virus reservoirs in Guinea. In

Seasonal Variation on The Prevalence of Ectoparasites in Rodents in Kilombero District, Tanzania

Journal of Applied Veterinary Science and Technology
Background: Significant health risks to humans and livestock are posed by rodents, which act as synanthropic pests damaging crops and food while harboring blood-feeding ectoparasites.

Mopeia Virus–related Arenavirus in Natal Multimammate Mice, Morogoro, Tanzania

Emerging Infectious Diseases, 2009
A serosurvey involving 2,520 small mammals from Tanzania identified a hot spot of arenavirus circulation in Morogoro. Molecular screening detected a new arenavirus in Natal multimammate mice (Mastomys natalensis), Morogoro virus, related to Mopeia virus.

MHC-I alleles mediate clearance and antibody response to the zoonotic Lassa virus in Mastomys rodent reservoirs.

PLoS Neglected Tropical Diseases
West African Mastomys rodents are the primary reservoir of the zoonotic Lassa virus (LASV). The virus causes haemorrhagic Lassa fever and considerable mortality in humans. To date, the role of Mastomys immunogenetics in resistance to, and persistence of,

Novel Arenavirus, Zambia

Emerging Infectious Diseases, 2011
To investigate arenavirus in Zambia, we characterized virus from the kidneys of 5 arenavirus RNA–positive rodents (Mastomys natalensis) among 263 captured.

Geographic distribution and genetic characterization of Lassa virus in sub-Saharan Mali. [PDF]

PLoS Neglected Tropical Diseases, 2013
Lassa fever is an acute viral illness characterized by multi-organ failure and hemorrhagic manifestations. Lassa fever is most frequently diagnosed in Nigeria, Sierra Leone, Liberia, and Guinea, although sporadic cases have been recorded in other West ...

Two Novel Arenaviruses Detected in Pygmy Mice, Ghana

Emerging Infectious Diseases, 2013
Two arenaviruses were detected in pygmy mice (Mus spp.) by screening 764 small mammals in Ghana. The Natal multimammate mouse (Mastomys natalensis), the known Lassa virus reservoir, was the dominant indoor rodent species in 4 of 10 sites, and accounted ...

The effect of vagotomy on enterochromaffin-like cells in Mastomys natalensis

Journal of the Autonomic Nervous System, 1996
The effect of vagotomy on the development of ECL cell tumours was analyzed during drug-induced hypergastrinemia in Mastomys natalensis, a rodent prone to develop ECL cell tumours. Untreated animals were compared with animals receiving the histamine2-receptor blocker loxtidine (LOX) and with animals subjected to unilateral subdiaphragmatic vagotomy ...
