Gammaherpesvirus carrier status of black wildebeest (Connochaetes gnou) in South Africa.
Malignant catarrhal fever (MCF) is an economically important disease primarily of domestic cattle with a high case fatality rate. It is caused by either alcelaphine herpesvirus type 1 (AlHV-1) or ovine herpesvirus type 2 (OvHV-2). The major reservoir host of AlHV-1 is the blue wildebeest (Connochaetes taurinus), but it is generally accepted that the black wildebeest (Connochaetes gnou) is also ...
متن کاملParasites of domestic and wild animals in South Africa. XVI. Helminth and arthropod parasites of blue and black wildebeest (Connochaetes taurinus and Connochaetes gnou).
Fifty-five blue wildebeest ( Connochaetes taurinus ) were shot for parasite recovery at approximately monthly intervals during a period of 13 months in the Kruger National Park. Thirteen nematode species, 4 cestode species, 1 trematode, the larvae of 5 oestrid flies, 3 lice species, 7 ixodid tick species, 1 mite species and the nymphae of a pentastomid were recovered. The seasonal prevalence of...
متن کاملProtozoa and digestive tract parameters in blue wildebeest (Connochaetes taurinus) and black wildebeest (Connochaetes gnou), with description of Entodinium taurinus n. sp.
Rumen contents from four blue wildebeest (Connochaetes taurinus) and six black wildebeest (Connochaetes gnou) were collected from two locations during two winter culling seasons. A total of 16 species of protozoa were found in blue wildebeest with Dasytricha ruminantium, Opisthotrichum janus and Ostracodinium gracile occurring in all four animals. In black wildebeest, 23 species of protozoa wer...
متن کاملWildebeest-derived malignant catarrhal fever: unusual epidemiology in South Africa.
The epidemiology of wildebeest-derived malignant catarrhal fever in South Africa differs from the worldwide accepted pattern. Here the occurrence of the disease is often not related to close contact between cattle and wildebeest, and most cases are observed during late winter and spring, when wildebeest calves are 8-10 months old. This is in contrast to the situation in Kenya and Tanzania, wher...
متن کاملEffect of competition on niche dynamics of syntopic grazing ungulates: contrasting the predictions of habitat selection models using stable isotope analysis
Background: Theories of density-dependent habitat selection provide two solutions for co-existence of competing species. The niche compression hypothesis predicts that species reduce their respective niche breadths in response to inter-specific competition. Alternatively, if the species have similar resource preferences, the subordinate species may be forced to expand its niche to incorporate s...
