A Histopathological Survey of Aged Praomys (Mastomys) natalensis
Journal of Gerontology, 1982This histopathological study shows that Mastomys develops a wide variety of neoplastic and nonneoplastic lesions with age. In comparing neoplastic lesions of Mastomys with those generally found in mice and rats, Mastomys is more or less unique with respect to the development of lymphoepithelial thymomas (40%), parathyroid adenomas (11%), prostatic ...

An electrophoretic polymorphism in the serum transferrins of Praomys (Mastomys) natalensis
Biochemical Genetics, 1976Three serum transferrin phenotypes of Praomys (Mastomys) natalensis, and African rodent having a high incidence of many varieties of spontaneous neoplasms, were detected by electrophoresis and autoradiography. On electrophoresis, transferrin of Trf-K was found to be a protein that migrates slowly toward the cathode, whereas that of Trf-M migrates ...

Rattus (Mastomys) natalensis (African mouse, mastomys)
1968Identification of the X chromosome is unequivocal. In females, the two X chromosomes may differ in morphology, one being more metacentric than the other, presumably the result of differential heteropycnotic behavior.

Production of Tumours in Rattus (Mastomys) natalensis by Polyoma Virus
Nature, 1960Rattus (Mastomys) natalensis, the multi-mammate mouse, is an African rodent intermediate in size between the rat and the mouse. These animals have been used in microbiological studies because they are highly susceptible to infection by plague bacilli1, Schistosoma mansoni 2, and Borrelia duttonii 3.

Naturally occurring autoantibodies in aged Praomys (Mastomys) natalensis
Clinical Immunology and Immunopathology, 1981Abstract One hundred and thirty-five sera from aged Mastomys were screened for the presence of spontaneously occurring autoantibodies using an indirect immunofluorescence technique. Such antibodies appeared to be relatively frequent and a number of different tissue specificities were observed.

Trichobezoars in praomys (mastomys) natalensis
2019We have in a rat model studied the role of gastric neuroendocrine cells in the regulation of gastric function and growth and given indication for an important role of these cells in physiology and human carcinogenesis. Because of the high incidence of spontaneous tumors in the glandular stomach of mastomys (Praomys (mastomys) natalensis), we wanted to ...

Experimental Prostatitis in Female Mastomys natalensis – a Preliminary Report
Urologia Internationalis, 2010Female Mastomys natalensis were inoculated with a suspension of Klebsiella pneumoniae into the bladder. All animals developed prostatitis without urinary tract infection between the 9th and the 12th day after inoculation. 104––105 CFU of K. pneumoniae per gram prostatic tissue could be cultivated.

Filarial infections of "Mastomys natalensis" and their relevance for experimental chemotherapy
Acta tropica, 1981Experimental filarial infections of Mastomys natalensis, strain GRA Giessen, with Litomosoides carinii, Dipetalonema viteae, Brugia malayi (subperiodic), and Brugia pahangi were compared. Mean prepatent periods of 52, 57, 107, and 73 days p.i. were observed after subcutaneous inoculation of 40, 50, 85, and 70 infective larvae of L. carinii, D.

Mastomys natalensis as an experimental host for Leishmania mexicana mexicana
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1978Young multimammate rats (Mastomys natalensis) can be readily infected when inoculated intradermally with the amastigotes of Leishmania mexicana mexicana. Lesions appear at the site of inoculation in the second week of infection and continue to increase in size for the first month; amastigotes can be detected during this period.
