the ixodid tick burdens of various large ruminant species in south african nature reserves.	the ixodid tick burdens of eland (taurotragus oryx), greater kudu (tragelaphus strepsiceros), nyala (tragelaphus angasi), bushbuck (tragelaphus scriptus) and giraffe (giraffa camelopardalis) in the kruger national park, transvaal; of african buffalo (syncerus caffer) and nyala in the hluhluwe game reserve, natal; and of gemsbok (oryx gazella) in the mountain zebra national park, an eland in the thomas baines nature reserve and an eland and greater kudu in the andries vosloo kudu reserve, eastern ...	1983	6646664
buffalo in the northern natal game parks show no serological evidence of infection with foot-and-mouth disease virus.	a total of 594 sera collected from buffalo (syncerus caffer) in the hluhluwe/umfolozi game reserve complex, ndumu game reserve and the eastern shores of lake st lucia were examined for antibody to sat 1, 2 and 3 types of foot-and-mouth disease (fmd) virus in neutralization tests. no neutralization of sat 2 or 3 viruses was exhibited by any of the sera tested at final dilutions greater than 10. a small proportion (2,9%) of sera neutralized sat 1 virus at dilutions up to 10, but these were conside ...	1985	2995896
foot and mouth disease: the experience of south africa.	foot and mouth disease (fmd) is endemic in african buffalo (syncerus caffer) in the kruger national park (knp) and surrounding game parks in south africa. the last outbreak of the disease in domestic stock outside the fmd control zone occurred in 1957. due to the success in containing the disease, the country was accorded zone freedom from fmd without vaccination by the office international des epizooties (oie: world organisation for animal health) in 1995. this status was lost in september 2000 ...	2002	12523712
the host status of african buffaloes, syncerus caffer, for rhipicephalus (boophilus) decoloratus.	the objective of this study was to assess the host status of african buffaloes, syncerus caffer, for the one-host tick rhipicephalus (boophilus) decoloratus. to this end the r. (b.) decoloratus burdens of ten buffaloes examined in three north-eastern kwazulu-natal province (kzn) nature reserves were compared with those of medium-sized to large antelope species in these reserves and in the southern kruger national park (knp), mpumalanga province. the r. (b.) decoloratus burdens of the buffaloes w ...	2006	17058441
occurrence of theileria parva and other haemoprotozoa in cattle at the edge of hluhluwe-imfolozi park, kwazulu-natal, south africa.	theileria parva, the most important bovine theilerial species in sub-saharan africa, causes widespread mortality and morbidity in endemic areas. a survey was conducted using buffy-coat specimens from 60 apparently healthy adult communally herded nguni-type cattle at the northeastern edge of the hluhluwe-imfolozi park to determine, by means of pcr and reverse line blot (rlb) hybridisation, the occurrence of theileria and babesia species. the presence of trypanosoma species was determined using pc ...	2010	20649154
molecular characterisation of mycobacterium bovis isolated from african buffaloes (syncerus caffer) in hluhluwe-imfolozi park in kwazulu-natal, south africa.	bovine tuberculosis (btb), a chronic disease of mammals caused by mycobacterium bovis, is a threat to south african wildlife. it has been reported that african buffaloes (syncerus caffer) are reservoir hosts of btb in south african wildlife populations. this study reports on the molecular identification and typing of 31 m. bovis isolates collected between 1993 and 2008, mainly from buffaloes but also from two lions and a bush pig, in the hluhluwe-imfolozi park (hip) in kwazulu-natal. to study th ...	2011	23327208
virulence of trypanosoma congolense strains isolated from cattle and african buffaloes (syncerus caffer) in kwazulu-natal, south africa.	trypanosoma congolense and trypanosoma vivax are major species that infect cattle in north-eastern kwazulu-natal (kzn), south africa. of the two genetically distinct types of t. congolense, savannah and kilifi sub-groups, isolated from cattle and tsetse flies in kzn, the former is more prevalent and thought to be responsible for african animal trypanosomosis outbreaks in cattle. furthermore, variation in pathogenicity within the savannah sub-group is ascribed to strain differences and seems to b ...	2014	25685920
field application of immunoassays for the detection of mycobacterium bovis infection in the african buffalo (syncerus caffer).	the african buffalo (syncerus caffer) is considered the most important maintenance host of bovine tuberculosis (btb) in wildlife in southern africa. the diagnosis of mycobacterium bovis infection in this species mostly relies on the single intradermal comparative tuberculin test (sictt). as an alternative, the bovigam® 1g, an interferon-gamma (ifn-γ) release assay, is frequently used. the test performance of cell-mediated immunity (cmi-) and humoral immunity (hi-) based assays for the detection ...	2016	26827841
wildlife on the move: a hidden tuberculosis threat to conservation areas and game farms through introduction of untested animals.	in south africa, african buffaloes ( syncerus caffer ) are one of the wildlife maintenance hosts for bovine tuberculosis (btb) and play a key role in the spread of the disease to other wildlife species and potentially back to cattle. we report a trace-back investigation following the diagnosis of btb in a previously btb-free provincial game reserve, founded in the early 1990s in the north west province of south africa (sa). using the intradermal tuberculin and interferon gamma tests, we detected ...	2016	27537933
