African beetles Onthophagus gazella from both sexes were analyzed by electrophoresis for an investigation of esterase isozymes using alpha-naphthyl propionate and methylumbelliferyl propionate as substrates. Only one of the esterases (Est. 6) reacted with one of the substrates (alpha-naphthyl propionate). Six areas of activity were found, two of them being polymorphic (Est. 3 and Est. 4). For p...

Introduction: Computed tomography (CT) is an imaging technique with gives us an opportunity to review cross sections of the body in live animals. In veterinary medicine although CT is mostly used for diagnostic purposes in small animals, but in recent years CT also has been used as a non invasive modality in non clinical studies. Jebeer Gazelle (Gazella bennettii) is one of the species of the g...

During a pilot survey of the parasites of some artiodactylids in the Kalahari Gemsbok National Park a new species of Trichostrongylus Looss, 1905 was recovered from the small intestine of a steenbok, Raphicerus campestris (Thunberg, 1811), a gemsbok, Oryx gazella (Linnaeus, 1758), and a red hartebeest, Alcelaphus buselaphus (Pallas, 1766). The male spicules were 0,120-0,148 mm long and an ear-s...

An effective anaesthesia protocol was developed for adult free-ranging gemsbok (Oryx gazella) using a combination of A3080, medetomidine and ketamine. A short induction time; good muscle relaxation, adequate oxygenation and stable heart rate and respiration rate characterised this anaesthetic regime. Equal doses of A3080 and medetomidine (22-45 microg/kg) plus 200 mg of ketamine were administer...

We conducted a comparative evaluation of 12S rRNA and 16S rRNA genes of the mitochondrial genome for molecular differentiation among three oryx species (Oryx leucoryx, Oryx dammah and Oryx gazella) with respect to two closely related outgroups, addax and roan. Our findings showed the failure of 12S rRNA gene to differentiate between the genus Oryx and addax, whereas a 342-bp partial sequence of...

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...

Sera from various wild ruminants co-existing in the same habitats with cattle had haemagglutination-inhibition (HI) antibodies as high as those in the cattle. Sera from wildebeest (Connochaetes taurinus), kongoni (Alcelaphus cokei), Thomson’s gazelle (Gazella thomsonii), eland (Taurotragus oryx) and the African buffalo (Syncerus caffer) had titers ranging from 64 to 128. Zebra (Equus burchelli)...
