| dilution effect in bovine tuberculosis: risk factors for regional disease occurrence in africa. | changes in host diversity have been postulated to influence the risk of infectious diseases, including both dilution and amplification effects. the dilution effect refers to a negative relationship between biodiversity and disease risk, whereas the amplification effect occurs when biodiversity increases disease risk. we tested these effects with an influential disease, bovine tuberculosis (btb), which is widespread in many countries, causing severe economic losses. based on the btb outbreak data ... | 2013 | 23804614 |

| effect of host diversity and species assemblage composition on bovine tuberculosis (btb) risk in ethiopian cattle. | current theories on diversity-disease relationships describe host species diversity and species identity as important factors influencing disease risk, either diluting or amplifying disease prevalence in a community. whereas the simple term 'diversity' embodies a set of animal community characteristics, it is not clear how different measures of species diversity are correlated with disease risk. we therefore tested the effects of species richness, pielou's evenness and shannon's diversity on bov ... | 2017 | 28134065 |
| ecology and epidemiology of rabies in humans, domestic animals and wildlife in namibia, 2011-2017. | rabies is a fatal zoonotic disease that causes a heavy burden on societies. namibia, a country in southern africa, is aiming at controlling the disease in its main reservoir, the domestic dog. to facilitate the implementation comprehensive information on the ecology and epidemiology of the disease and surveillance is of utmost importance. the study presented assesses the baseline data for both human and animal rabies surveillance in namibia in recent times and establishes correlations with ecolo ... | 2019 | 30990805 |
| experimental screening studies on rabies virus transmission and oral rabies vaccination of the greater kudu (tragelaphus strepsiceros). | rabies in the greater kudu (tragelaphus strepsiceros) in namibia is unique and found in such magnitude as has not been reported elsewhere in southern africa. reasons as to why kudus appear to be exceptionally susceptible to rabies still remain speculative at best. because the current severe rabies endemic in kudus continues to have an enormous negative impact on the namibian agricultural sector, we set out to question existing dogmas regarding the epidemiology of the disease in a unique experime ... | 2018 | 30413745 |
| baiting studies on oral vaccination of the greater kudu (tragelaphus strepsiceros) against rabies. | rabies in the greater kudu (tragelaphus strepsiceros), one of the largest african antelopes, is a phenomenon unique to namibia. since the mid-1970s, the country has been plagued by two epizootics that claimed thousands of casualties among the indigenous kudu population. reasons as to why kudus appear to be exceptionally susceptible to the disease still remain speculative at best. because the namibian economy relies heavily on trophy hunting, game meat hunting, and ecotourism, the current severe ... | 2018 | 32214946 |
| clinical management of third phalanx fractures in lesser (tragelaphus imberbis) and greater kudu (tragelaphus strepsiceros). | two greater kudu ( tragelaphus strepsiceros ) and one lesser kudu ( t. imberbis ) from two zoological institutions presented with overgrown front hooves, and were diagnosed with fractures of the third phalanges in the affected digits. both greater kudu had milder lamenesses at diagnosis, and were managed conservatively with hoof trims, stall rest, and nonsteroidal anti-inflammatory medications. ongoing management through regular hoof trims led to improvement and eventual resolution of lameness. ... | 2017 | 28363042 |
| greater kudu (tragelaphus strepsiceros) mortality in european zoological institutions: a retrospective study. | a questionnaire was sent to 39 european institutions holding greater kudus (tragelaphus strepsiceros), in order to determine the causes of captive greater kudu mortality. all reported macroscopic lesions and histopathologic observations, as well as other information regarding individuals that died, were analyzed to determine the most affected body systems and causes of death. overall response rate was 31%, and 131 individuals were included in the study. the most frequently affected body systems ... | 2016 | 27468026 |
| metagenome sequencing of the greater kudu (tragelaphus strepsiceros) rumen microbiome. | ruminant herbivores utilize a symbiotic relationship with microorganisms in their rumen to exploit fibrous foods for nutrition. we report the metagenome sequences of the greater kudu (tragelaphus strepsiceros) rumen digesta, revealing a diverse community of microbes and some novel hydrolytic enzymes. | 2015 | 26272573 |
| meiotic behaviour of evolutionary sex-autosome translocations in bovidae. | the recurrent occurrence of sex-autosome translocations during mammalian evolution suggests common mechanisms enabling a precise control of meiotic synapsis, recombination and inactivation of sex chromosomes. we used immunofluorescence and fish to study the meiotic behaviour of sex chromosomes in six species of bovidae with evolutionary sex-autosome translocations (tragelaphus strepsiceros, taurotragus oryx, tragelaphus imberbis, tragelaphus spekii, gazella leptoceros and nanger dama ruficollis) ... | 2016 | 27136937 |
| trophy hunting and sustainability: temporal dynamics in trophy quality and harvesting patterns of wild herbivores in a tropical semi-arid savanna ecosystem. | the selective nature of trophy hunting may cause changes in desirable phenotypic traits in harvested species. a decline in trophy size of preferred species may reduce hunting destination competitiveness thus compromising the sustainability of trophy hunting as a conservation tool. we explored the trophy quality and trends in harvesting patterns (i.e., 2004-2015) of cape buffalo (syncerus caffer), african elephant (loxodonta africana), greater kudu (tragelaphus strepsiceros) and sable (hippotragu ... | 2016 | 27736930 |
| rabies in kudu (tragelaphus strepsiceros). | cycles of terrestrial rabies are associated with carnivores. in non-carnivorous species, rabies typically occurs as a spill-over from the carnivore reservoir and quickly encounters a dead end in such species. one major exception to this scenario has been an ongoing epizootic of rabies in the greater kudu, an african antelope. these herbivores are found in high densities in southern africa, but rabies cycles have only been described from namibia, a vast country located in the south western region ... | 2012 | 22712421 |
