| studies on schistosoma bovis in ethiopia. | schistosoma bovis occurs in at least seven of the 14 rovinces of ethiopia. results of faecal and snail surveys in three foci are reported. adwa. one collection showed that nine out of 26 bulinids were infected with s. bovis. the snail host was a tetraploid form of bulinus (n = 36). the examination of 200 specimens of cattle faces revealed no s. bovis eggs, which was attributed to poor technique or light infection. gewani. the snail host was bulinus abyssinicus, which was also infected with s. ha ... | 1975 | 808181 |
| seasonal patterns of rodents, fleas and plague status in the western usambara mountains, tanzania. | field and commensal rodents were live-trapped at three villages in an active focus of plague (yersinia pseudotuberculosis pestis) in lushoto district, western usambara mountains, tanga region, tanzania, from december 1983 to november 1984. their flea ectoparasites were collected, identified and counted. the rodent carcasses were serologically examined for specific plague antibodies and antigens, and bacteriologically examined for bipolar staining bacilli. a total of 1758 traps were set during th ... | 1989 | 2519642 |
| the brown ear tick rhipicephalus appendiculatus neumann (acarina: ixodidae) and associated tick species on wild and domestic hosts at muguga, kenya. | during a study of an experimental population of rhipicephalus appendiculatus and its transmission of bovine theileriosis to cattle, some supplementary information was obtained on the role of rodents and the small carnivores in the development and maintenance of r. appendiculatus populations. observations were also made on other common tick species found on these hosts. a total of 530 individual hosts were examined during the 4-yr period, of which the majority included, among the carnivores, the ... | 1985 | 3998963 |
| [analysis of allozyme variability in populations of three species of brush-haired mice of species lophuromys (rodentia, muridae) from the bale mountains national park in ethiopia]. | allozyme variability was examined in populations of three endemic species of the species complex lophuromys flavopunctatus sensu lato: l. chrysopus, l. brevicaudus, and l. melanonyx. these species substitute each other in adjacent latitudinal belts of the bale massif in ethiopia. a deficit of heterozygotes at several loci was found in most samples of all species studied. moreover, the samples included animals homozygous for two or three minor alleles and heterozygous for alleles that are rare an ... | 2000 | 11190478 |
| schistosomes of small mammals from the lake victoria basin, kenya: new species, familiar species, and implications for schistosomiasis control. | recent schistosomiasis control efforts in sub-saharan africa have focused nearly exclusively on treatment of humans with praziquantel. however, the extent to which wild mammals act as reservoirs for schistosoma mansoni and therefore as sources of renewed transmission following control efforts is poorly understood. with the objective to study the role of small mammals as reservoir hosts, 480 animals belonging to 9 rodent and 1 insectivore species were examined for infection with schistosomes in k ... | 2010 | 20380765 |
| reproduction and population dynamics of mastomys natalensis smith, 1834 in an agricultural landscape in the western usambara mountains, tanzania. | the multimammate rat, mastomys natalensis smith 1834, is a dominant species in agro-ecosystems in sub-saharan africa, but adapts quickly to changes in non-agricultural landscape, particularly woodlands and forests. in this study we report on reproduction and population dynamics of m. natalensis in deforested high elevation localities in the usambara mountains, north-east tanzania. we conducted capture-mark-recapture studies in 2002-2004, and established that reproduction of m. natalensis takes p ... | 2007 | 21396040 |
| factors associated with flea infestation among the different rodent species in mbulu and karatu districts, northern tanzania. | flea infection with the bacterium, yersinia pestis is acquired from reservoirs which include several rodents and other small mammals. in areas that are endemic of plague, reservoirs of y. pestis and various flea vectors are responsible for perpetuating existence of the disease. the objective of this cross sectional study was to investigate the magnitude and factors associated with flea infestation among different rodent species of northern tanzania, where outbreaks of plague have been recently r ... | 2013 | 26591705 |
