Patterns of Neoplastic and Nonneoplastic Diseases of Praomys (Mastomys) Natalensis
1975We wish to introduce a unique animal, the mastomys, which is not well known to the scientific coummunity. Mastomys develop certain diseases that constitute suitable animal models for study and experimentation on 1) chemotherapy of immunological disorders, and 2) tumorigenesis in such immunological disorders.

On Dipetalonema viteae infection of Mastomys natalensis.
Tropenmedizin und Parasitologie, 1979Experimental infections were carried out with the tissue-dwelling filaria Dipetalonema viteae using the argasid tick Ornithodorus moubata as the intermediate and the multimammate rat Mastomys natalensis (Strain GRA Giessen) as the final host. The optimum infective dose was found to be 50 third-stage larvae, which produced patent infections and the ...

Malignant Argyrophilic Gastric Carcinoids of Praomys (Mastomys) natalensis
Science, 1969Cells of carcinoid tumors which arise in the glandular stomach of old male and female Praomys ( Mastomys ) natalensis contain argyrophil granules when tissues fixed in formalin are colored with solutions of silver salts.

["Keratoacanthomas" in mastomys natalensis (author's transl)].
Archives for dermatological research = Archiv fur dermatologische Forschung, 197654 Tumors of Mastomys natalensis (GRA Giessen), described in the literature as "Keratoacanthomas" were investigated by light and electron microscopy. They are induced by a virus of the Papova group. Their histogenesis and their course are very different from human keratoacanthoma. The results reveal problems related to experimental animal tumour models

Association of autoantibodies and pathological changes in aged Praomys (Mastomys) natalensis
Clinical Immunology and Immunopathology, 1982An attempt is made to relate the presence of autoantibodies to pathological changes in aged Mastomys. It appeared that a direct relationship between one of the thymic changes (atrophy, hyperplasia, or neoplasia) and autoantibody formation was doubtful.

Effect of ivermectin on filariae ofMastomys natalensis
Parasitology Research, 1990The efficacy of ivermectin (Iv) was evaluated against four species of filariae, Litomosoides carinii, Acanthocheilonema viteae, Brugia pahangi and Brugia malayi in Mastomys natalensis. Animals with patent infections, induced with L3 larvae, by intravenous (iv) infusion of the respective microfilariae (Mf) (5 x 10(4) Mf per animal) or by intraperitoneal

Spatial patterns in Mastomys natalensis in Tanzania (Rodentia, Muridae)
Mammalia, 1996Nous avons etudie la preference d'habitat, la dispersion et les mouvements de Mastomys natalensis dans des jacheres et des champs de mais en Tanzanie. Pendant les periodes de faibles densites, les animaux semblaient eviter les espaces ouverts et etaient concentres dans les zones a riche vegetation.

Mastomys natalensis or Mastomys coucha. Correct species designation in animal experiments.
Tropical medicine and parasitology : official organ of Deutsche Tropenmedizinische Gesellschaft and of Deutsche Gesellschaft fur Technische Zusammenarbeit (GTZ), 1990Haemoglobin electrophoresis and chromosome analysis indicate that the widely used multimammate rat (chamois coloured) as experimental animal belongs to the species Mastomys coucha (Smith, 1836) and not, as commonly assumed, to Mastomys natalensis (Smith, 1834).

Productivity of Different Generations in a Population of Mastomys natalensis Rats in Tanzania
Oikos, 1993In Tanzania three different generation types can be recognized in Mastomys natalensis rats. The α-generation is born in the main breeding season and breeds in the next main breeding season. The β-generation is born in the main breeding season but reproduces already after abundant off-season rainfall.

Filaricidal effects of Cyclosporin-A against Dipetalonema viteae in Mastomys natalensis
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1984Outbred male Mastomys natalensis were injected subcutaneously with 100 infective larvae of Dipetalonema viteae obtained from Ornithodorus tartakovskyi. Groups of five animals were treated with 30 mg/kg of the immunosuppressive drug Cyclosporin-A daily for five days (experimental) or Miglyol 812 (control).
