Near infrared analysis of sugarcane (Saccharum spp hybrid) bud scales to predict resistance to Eldana stalk borer (Eldana saccharina Walker).
(2003)The eldana stalk borer (Eldana saccharina Walker) is the most serious pest of the Southern African sugarcane industry, and it is imperative that effective control measures are available to minimize economic damage. Because ... -
Novel cationic lipoplexes : characterization in cell culture in vitro and in vivo.
(2010)Amongst the more promising non-viral DNA vehicles are liposomes, with those derived from cationic lipids showing significant potential, despite moderate transfection levels in vivo. This study has investigated the effect ... -
Novel siRNA lipoplexes : their targeted and untargeted delivery to mammalian cells in culture.
(2011)The high gene knockdown specificity and efficiency of RNA interference (RNAi) provides a potentially viable avenue for the development of a new class of nucleic acid therapeutics for gene-based disease conditions. However, ... -
Optimisation of the randomly amplified polymorphic DNA (RAPD) technique for the characterisation of selected South African maize (Zea mays L.) breeding material.
(2000)Maize (Zea mays L.) is an important agronomic crop with the maize industry forming an important component of the South African economy. Considerable effort has been directed towards the genetic improvement of maize through ... -
Phylogenetic and evolutionary analysis of the Borna disease virus.
(2002)The characteristic trait of the Borna disease virus is that it is a complicated single negative stranded RNA virus that is capable of infecting a wide array of mammalian species including human beings. It has been implicated ... -
Population genetic diversity of Fasciola spp. from Mpumalanga and KwaZulu-Natal provinces of South Africa.
(2017)Fasciola hepatica and Fasciola gigantica have been identified as the species causing fascioliasis in ruminants and humans with intermediate species being reported as well. Studies have shown an economic loss in excess of ... -
Population genetics of Swakara sheep inferred using genome-wide SNP genotyping.
(2015)The pelts of Swakara sheep breed of Namibia are famous for their lustrous features and are unmatched in quality across the globe. These pelts occur in four subpopulations of white, grey, black and brown. The white pelt is ... -
Population genetics of the bearded vulture.
(2018)The bearded vulture (Gypaetus barbatus) is a large, long-lived bird which inhabits high-altitude mountains across Africa, Europe and Asia. Low breeding rates and heightened persecution over the last two centuries have left ... -
Prevalence and antibiotic sensitivity of enterotoxigenic Escherichia coli isolates in South African pig population.
(2015)Escherichia coli (E. coli) are among the leading bacterial causes of diarrhoea and edema in newborn and weaned pigs. Pathogenic strains of E. coli are classified into enterotoxigenic E. coli (ETEC), enterohemorrhagic E. ... -
Prevalence and antibiotic susceptibility of Listeria monocytogenes isolated from broiler chickens within Durban, South Africa.
(2016)Abstract available in PDF file. -
Quantification of time-dependent redox signalling in the Tpx1/Pap1 pathway in Schizosaccharomyces pombe.
(2019)Reactive oxygen species (ROS) can damage cellular components leading to cell death, but paradoxically, ROS also play essential roles in metabolism and signalling in eukaryotic cells. Dysregulation of this balance is ... -
Regulation of the thioredoxin system in Saccharomyces cerevisiae.
(2013)The thioredoxin system consisting of thioredoxin (Trx), thioredoxin reductase and NADPH plays a significant role in a large number of redox-dependent processes such as DNA synthesis and anti-oxidant defense. Elevated levels ... -
Structural analysis of the mycobacterium tuberculosis redox defence network reveals a unique bi-fan motif design associated with hydrogen peroxide reduction.
(2017)Abstract available in PDF file. -
The taxonomy and systematics of the bee genus Scrapter (Colletidae: Colletinae: Scraptrini)
(2016)Scrapter is a southern African endemic pollen-collecting genus consisting of 43 described species with 13 species also occurring in neighbouring countries such as Lesotho, Mozambique, Namibia and Zimbabwe. Classification ... -
Testing the utility of DNA barcoding for the rapid assessment of Formicidae biodiversity in the eThekwini region.
(2014)The biodiversity of Durban (eThekwini municipality) in KwaZulu Natal is primarily threatened by urbanization although other factors such as climate change and the spread of invasive species also pose a significant threat. ... -
Testing the utility of DNA barcoding in South African Hemiptera : using eThekwini species as a case study.
(2017)The eThekwini municipal region and surrounding areas (Durban, Kwazulu-Natal, South Africa) are situated within the globally important Maputaland-Pondoland-Albany biodiversity hotspot. The biodiversity present in this region ... -
Testing the utility of DNA barcoding on dipteria of eThekwini.

The role of interleukin-10 promoter polymorphisms in HIV-1 susceptibility and primary HIV-1 pathogenesis.
(2007)Host genetic factors may partially account for the uneven distribution of HIV infection worldwide. In addition to influencing relative susceptibility to HIV, host genetic factors may also affect the rate of disease progression ... -
The transformation of South African soya bean cultivars with a synthetic Basta resistance gene.
(1995)The development of a genetic engineering system for soya bean (Glycine max L.) is described in this thesis. Routine tissue culture regeneration systems were developed for South African cultivars of soya bean despite the ...
