In order to detect the prevalence of Cowdria ruminantium in the vector tick, Amblyomma hebraeum, free-living, unfed adult ticks were collected with the aid of pheromone/CO2 traps. Ticks were collected at the Rietgat communal grazing area, as well as in the southwestern Kruger National Park and in the Songimvelo Game Reserve, all located in heartwater-endemic areas of South Africa. The presence ...

Aegyptianella botuliformis n. sp. (Rickettsiales: Anaplasmataceae) isolated from helmeted guineafowls Numida meleagris from the Kruger National Park is described. The rickettsia occurs within a membrane-bound vacuole in the cytoplasm of erythrocytes with up to 8 organisms in a mature inclusion. The initial body resembles that of Aegyptianella pullorum. The tightly packed, sausage-shaped interme...

J. Kruger and D. Dunning (1999) argued that the unskilled suffer a dual burden: Not only do they perform poorly, but their incompetence robs them of the metacognitive ability to realize it. J. Krueger and R. A. Mueller (2002) replicated these basic findings but interpreted them differently. They concluded that a combination of the better-than-average (BTA) effect and a regression artifact bette...

The presence of a di-unsaturated highly branched isoprenoid (HBI) lipid biomarker (diene II) in Southern Ocean sediments has previously been proposed as a proxy measure of palaeo Antarctic sea ice. Here we show that a source of diene II is the sympagic diatom Berkeleya adeliensis Medlin. Furthermore, the propensity for B. adeliensis to flourish in platelet ice is reflected by an offshore downwa...

A new species of Paracooperia Travassos, 1935 was found in the small intestines of 4 bushbuck, Tragelaphus scriptus (Pallas, 1766), and 3 greater kudu, Tragelaphus strepsiceros (Pallas, 1766), all culled in the Kruger National Park. The nematodes appear to be widespread in the Park, since the bushbuck originated from Skukuza in the central part of the Park, 2 of the 3 kudu from near Malelane in...

In 1948, in the Institute of Hans Kopfermann in Gottingen, where I had just completed my experimental diplom-arbeit under Peter Brix, it was well known that I was supporting myself and my studies by the repair and barter of pre-war radios. So when Hubert Kruger, then one of Kopfermanns assistants, wanted to launch a search for rf spectra in solids, I was a natural choice and was signed on as hi...

A total of 264 scrub hares (Lepus saxatilis) were examined for ixodid ticks at various localities in the Kruger National Park, eastern Transvaal Lowveld. Thirteen tick species were recovered from these hares. The seasonal abundances of the immature stages of Amblyomma hebraeum, Amblyomma marmoreum, Hyalomma truncatum, Rhipicephalus appendiculatus, Rhipicephalus evertsi evertsi, Rhipicephalus si...
