| further observations on the relationship and distribution of schistosoma margrebowiei and s. leiperi in central southern africa. | a further survey in east caprivi, chobe national park, okavango swamps and kavango was undertaken in june 1976. no evidence of lechwe schistosomes was found in droppings of african buffalo (syncerus caffer) nor baboons (papio ursinus) living in lechwe habitats. it was thought that they were not capable of spreading or maintaining these parasites outside the confines of the known distribution of kobus sp. the role of goats was equivocal but probably they too are poor hosts. kavango, an endemic ar ... | 1977 | 599275 |
| the incidence of tuberculosis in lechwe (marsh antelope). | of the 238 specimens of tissue collected from 70 lechwe (marsh antelope) 79 yielded m. bovis, 1 yielded a mixed growth of m. bovis and an 'atypical' mycobacterium and 6 yielded 'atypical' mycobacteria; the 'atypical' mycobacteria were probably contaminants. of the 63 lechwe killed as a 1 in 10 random sample from four herds, m. bovis was obtained from 21 animals, indicating that 33% of wild lechwe are infected with tuberculosis. | 1977 | 339450 |
| preliminary observations on the distribution, definitive hosts and possible relation with other schistosomes, of schistosoma margrebowiei, le roux, 1933 and schistosoma leiperi, le roux, 1955. | in attempting to define the south western limits of the distribution of schistosoma margrebowiei and s. leiperi and investigating their apparent limited distribution in relation to their snail hosts it was found that there was little overlap in the distribution of s. margrebowiei and s. leiperi and that of the human parasites s. haematobium and s. mansoni, and no overlap with s. mattheei within the area surveyed. it is suggested that the presence of either or both lechwe schistosomes prevented t ... | 1976 | 965705 |
| lekking behavior in kafue lechwe. | the kafue lechwe (kobus leche kafuensis) exhibits lekking behavior in which a number of males occupy small territories clustered together in discrete areas where females go for mating. similar behavior in antelope is known only in the uganda kob (kobus kob thomasi). lechwe lekking occurs only during a main rutting season although some breeding occurs throughout the year. | 1976 | 17771760 |

| blood parasites of some wild bovidae in botswana. | blood smears from a total of 282 wild bovidae from ngamiland, botswana were examined for the presence of blood parasites. the following species were sampled: 190 african buffalo, 23 impala, 10 blue wildebeest, 18 tsessebe, 1 eland, 13 lechwe, 16 kudu and 11 sable antelope. in addition, blood from 36 of the above antelope and from a further 48 buffalo was inoculated into rodents to test for the presence of trypanosomes. an anaplasm morphologically indistinguishable from anaplasma marginale theile ... | 1975 | 813170 |
