    Cytotaxonomy of rodent species from Ethiopia, Kenya, Tanzania and Zambia
    (Belg. J. Zool, 2005) Corti, M.; Castiglia, R.; Colangelo, P.; Capanna, E.; Beolchini, F.; Bekele, A.; Oguge, N. O.; Makundi, R. H.; Sichilima, A. M.; Leirs, H.; Verheyen, W.; Verhagen, R.
    An extended survey of taxa belonging to two genera of Cricetomyinae (Cricetomys and Saccostomus), one Gerbillinae (Gerbilliscus), eight Murinae (Acomys, Aethomys, Arvicanthis, Lemniscomys, Mus (Nannomys), Mastomys, Grammomys, Stenocephalemys) and one Myoxidae (Graphiurus) was carried out as part of the EU programme “Staplerat” involving Ethiopia, Kenya, Tanzania and Zambia. Here we report the diploid and autosomal fundamental numbers of these rodent taxa. Seventeen of them were unknown, for four we report chromosomal variants and for another 16 new localities where they occur. We discuss their specific status taking into consideration our results together with data from literature and highlight the problems in taxonomy and systematics that are yet to be solved, due do their extended range and the occurrence of species complexes. We highlight cases for which there should be a re-evaluation of specific names that were not included in the last rodent checklist.

    Serological and molecular characterization of leptospira serovar Kenya from captive African giant pouched rats (Cricetomys gambianus) from Morogoro Tanzania
    (2004-03-07) Machangu, R.S.; Mgode, G.F.; Assenga, J.; Mhamphi, G.; Weetjens, B.; Cox, C.; Verhagen, R.; Sondij, S; Goris, M.G.; Hartskeerl, R.A.
    Two identical leptospiral isolates coded Sh9 and Sh25 obtained from the urine of captive African giant pouched rats (Cricetomys gambianus), destined for use as biodetector of antipersonnel landmines were typed as serovar Kenya using cross-agglutination absorption test and DNA fingerprinting with the insertion element sequences IS1533 and IS1500 derived primers. The two isolates were previously characterized using cultural and serological – microagglutination test as pathogenic leptospires of the serogroup Ballum, closely related to serovars Kenya and Peru. To our knowledge, this is the first reported in-depth characterization of leptospira isolates from Tanzania.
