The develolpment of a rapid diagnostic test for the detection of haemophilus ducrey.
(2010)Aim: To develop an antigen detection test that would quickly exclude H. ducreyi infection in individuals with genital ulcers. Materials and Methods: H. ducreyi strains A54 and A68 were grown on Modified Bieling (MB) ... -
Development of a laboratory river model to determine the environmental impacts of key xenobiotic compounds.
(1996)Microorganisms are increasingly used in toxicological studies to determine potential environmental impacts of xenobiotic compounds. A multi-stage laboratory model was developed to facilitate the examination of environmental ... -
The development of an in vitro system to assess the effect of arbuscular mycorrhizal fungi on cereal crops in KwaZulu-Natal, South Africa.
(2010)Cereal crops such as maize and sorghum are economically important in South Africa (SA) as a staple food diet. In order to meet the needs of South Africa’s growing population, higher yields in crop production need to be ... -
Effect of fermentation and nutritional conditions on the profile of flavour active ester compounds in beer.
(2011)During fermentation, the yeast Saccharomyces cerevisiae produces a broad range of aroma-active esters that are important for the desirable complex flavour of beer. The sensory threshold levels of these esters in beer are ... -
The effect of nitrate and nitrite supplementation on the biocorrosion of mild steel coupons in a loam soil system.
(2015)Microbially influenced corrosion is the participation of microorganisms in the corrosion process. This study determined the effect of nutrients, viz., nitrate and nitrite supplementation on the microbial corrosion of mild ... -
The effect of water treatment residues on soil microbial and related chemical properties.
(2003)Water treatment residue (WTR), a by-product of the water treatment process, consists primarily of precipitated hydroxides of the coagulants used in the water treatment process, along with sand, silt, clay, humic compounds, ... -
The effects of a cigarette carcinogen on glucocorticoid receptor methylation.
(2014)Small cell lung cancer (SCLC) is an aggressive disease with an extremely poor prognosis. Lung cancer has been linked to cigarette smoking. SCLCs are glucocorticoid insensitive due to reduced levels of glucocorticoid receptor ... -
The endosymbiotic bacteria of the South African bird cherry-oat aphid, rhopalosiphum padi.
(2018)Cereal crops play a major role in human diet as staple foods, especially in developing countries. These crops are a part of a few edible crops that are widely cultivated globally. However, the production of these crops is ... -
An Epidemiological study of gentamicin resistant gram negative bacteria with particular reference to pseudomonas aeruginosa at King Edward V111 Hospital, Durban
(1985)The sources of gentamicin resistant pseudomonads and enterobacteria were studied in detail. A total of 1703 gentamicin resistant gram negative bacilli (GRGNB) isolated from patients, staff and their immediate environment ... -
Epigentic silencing of the glucocorticoid receptor in small cell lung cancer cells.
(2013)Small cell lung cancer (SCLC) is an aggressive neuroendocrine tumour which secretes ACTH and other related peptides. Contrary to normal production by the pituitary, ACTH production is not inhibited by glucocorticoids (Gcs) ... -
Establishment of in vitro shoot multiplication and short-term embryo storage protocols for single genetic modification events in sugarcane.
(2013)Sugarcane (Saccharum spp. hybrids) is an important economic crop that accounts for more than 80% of world sugar production. Genetic improvement and selection to produce cultivars with traits of interest is difficult in ... -
Exploitation of indigenous fungi in low-cost ex situ attenuation of oil- contaminated soil.
(1997)The central aim of this study was to determine if indigenous fungi of an oil-contaminated soil could be effectively used in a low-cost bioremediation of the soil. Since some of the contaminant had been present at the ... -
Extraction, sequencing and bioinformatics analysis of DNA from dried blood spots.
(2016)The Africa Centre for Health and Population Studies has a demographic surveillance site 200km north of Durban at the Umkhanyakude district. In this setting, blood samples are routinely collected and used for the diagnosis ... -
Fate of antibiotic resistant enterococci and selected tetracycline resistance genes during wastewater treatment.
(2016)Abstract available in PDF file. -
Galactosylated liposomes with proton sponge capacity : a novel hepatocyte-specific gene transfer system.
(2012)Hepatocyte-directed liposomal gene delivery systems have received much attention in view of the present lack of suitable treatment alternatives for several liver-associated disorders. While targeting of liposomes to the ... -
Genetic analyses of a Southern African millipede (Bicoxidens Attems 1928)
(2014)Bicoxidens Attems, 1928 is an afrotropical millipede in the family Spirostreptidae which constitutes nine species. Based on the analysis of the male copulatory organs known as gonopods, Bicoxidens is monophyletic. However, ... -
Genetic characterization of robustness and fitness traits in South African indigenous chickens.

Glucocorticoid receptor promoter expression and apoptosis induction in small cell lung cancer.
(2013)Lung cancer is the most common cancer worldwide and is the fourth leading cause of death in South Africa. Lung cancer is categorised into two types; non-small cell lung cancer and small cell lung cancer (SCLC). SCLC ... -
Humic acid pretreatment for enhancing microbial removal of metals from a synthetic 'wastewater'.
(2004)The presence of heavy metal ions in waste streams is one of the most pervasive environmental issues of present times. A rotating biological contactor (RBC) was used to investigate the potential capacity of microbial ... -
Impact of irrigation water on the quality of fresh produce.
(2011)The consumption of minimally processed fresh fruit and vegetables has increased over the past years, mostly because of consumers awareness that fresh produce serves as a good source of vitamins, minerals and fibre. ...
