An intimate relationship exists between the transcriptional machinery and the chromosomal environment within which it functions. The histones package all chromosomal DNA into nucleosomes, yet mutations in individual histones have specific consequences for the expression of particular genes (Grunstein et al., 1992; Kruger et al., 1995). How can general DNA packaging proteins contribute to the sp...

This paper evaluated the capacity of SPOT VEGETATION time-series to monitor herbaceous fuel moisture content (FMC) in order to improve fire risk assessment in the savanna ecosystem of Kruger National Park in South Africa. In situ herbaceous FMC data were used to assess the Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), Vegetation Dryness Index (VDI), Im...

The value of the dung of game animals as a larval habitat for Culicoides species was briefly investigated in 1973/74 in the Kruger National Park, Transvaal, Republic of South Africa. A total of 4 species in the subgenus Avaritia was reared, 3 from elephant dung, 2 from zebra dung and 1 from the dung of buffalo. These early studies have recently led to more intensive rearing and a better underst...

Schistosoma hippopotami were collected from the right heart chambers and pulmonary arteries of Hippopotamus amphibius culled in the Kruger National Park. The schistosomes were subjected to scanning electron microscopy as well as optical microscopy. The results indicate that S. hippopotami is not conspecific to S. mansoni as suggested in the literature. On account of the morphology of certain te...

INTRODUCTION Spotted fever group rickettsioses are an interesting group of infections, which are increasing in incidence worldwide. CASE PRESENTATION Here we describe an imported case to the United Kingdom occurring in a patient who had recently visited Kruger National Park in South Africa - a highly endemic area for Rickettsia infections. Initial treatment with doxycycline failed but the pat...

A method for selecting the most effective arthropod repellent from stereoisomers of a compound, involving testing each stereoisomer of the compound for its effectiveness as an arthropod repellent against an arthropod of a particular genus and species, comparing the test results and selecting the most effective arthropod repellent stereoisomer from the stereoisomers of the compound, wherein the ...

Rift Valley fever (RVF) is a zoonotic mosquito-borne virus disease of livestock and wild ruminants that has been identified as a risk for international spread. Typically, the disease occurs in geographically limited outbreaks associated with high rainfall events and can cause massive losses of livestock. It is unclear how RVF virus persists during inter-epidemic periods but cryptic cycling of t...
