“…It was shown recently that the multimammate mouse, P. natalensis, comprises separate 32-chromosome and 36-chromosome populations in Rhodesia (Lyons, Green, Gordon & Walters, 1977a;1977b Individuals were anaesthetized with ether and given 103 mouse i.c.

SUMMARYBrains, spleens and livers of 2212 murids, 27 shrews and 7 dormice, trapped at 7 sites in Rhodesia, were tested in 277 pools for the presence of Rift Valley Fever virus. There were no isolations of Rift Valley Fever, but 69 isolations of an unidentified virus were obtained. Sixteen out of 867 sera had low-titre haemagglutination-inhibition activity against Rift Valley Fever antigen, but only one out of 1260 sera had neutralizing antibody. The evidence suggests that murids fail to encounter infection in nature and are unlikely to play a role in circulation and dissemination of Rift Valley Fever virus. Four out of seven widely distributed species of murid, Rhabdomys pumilio, Saccostomys campestris, Aethomys chrysophilus and Lemniscomys griselda, were shown to be capable of circulating amounts of virus likely to be infective for mosquitoes.

From the early work of MATTHEY (1954, 1955, 1966b) it was apparent that the autosomal fundamental number (autFN) remained constant despite 147 variations in the diploid number (Mastomys erythroleucus 2n = 38, aut FN = 52; Mastomys natalensis 2n = 36, autFN = 56; Mastomys huberti 2n = 32, autFN = 52).…”

“…Within the taxonomic group Mastomys natalensis (Smith, 1834) sensu latu (syn. Mastomys coucha Smith, 1834) an extreme degree of karyotype variability has been described with diploid numbers of 2n = 38, 36 and 32 (MATTHEY, 1954(MATTHEY, , 1955(MATTHEY, , 1958(MATTHEY, , 1965(MATTHEY, , 1966a(MATTHEY, , 1966b(MATTHEY, , 1967(MATTHEY, , 1970FoRD & HAMERTON, 1956;HuANG & STRONG, 1962;KRAL, 1971;LYONS et al, 1977;HALLETT, 1979;LEE & MARTIN, 1980). Nevertheless, MATTHEY (1955) thought that the 32 chromosome Mastomys specimens found at Oubangi (Central African Republic) belonged to a species different from Mastomys natalensis.…”
