Antibiotic resistance in triclosan heterotrophic plate count bacteria from sewage water
(North-West University, 2015)
The concentration of triclosan in antiseptics, disinfectants and preservatives in products exceeds the minimal lethal levels. Extensive use of triclosan and antibiotics results in bacterial resistance to their active ...
Investigation of the microbial diversity and functionality of soil in fragmented South African grasslands along an urbanization gradient
(2010)
The diversity of microorganisms and the influence of their enzymatic activities in soil are critical to the maintenance of good soil health. Changes in these parameters may be the earliest predictors of soil quality changes, ...
A PCR detection method for mutations in receptor–protein genes from Busseola fusca potentially involved in Bt–resistance
(North-West University, 2012)
Genetically modified (GM) crops attracted interest globally when use of these crops resulted in significant increases in yield and production. These increases were due to protection of crops from pests, weeds and diseases. ...
Diversity of gut–microorganisms in Bt–resistant and Bt–susceptible larvae of the maize stem borer (Busseola fusca) (Lepidoptera : Noctuidae)
(North-West University, 2012)
Maize is one of Africa’s main food sources. It is therefore important to protect this crop
against pests such as the maize stem borer Busseola fusca. Genetically modified Bacillus
thuringiensis (Bt) maize has been shown ...
Genetic studies of Busseola fusca (Lepidoptera : Noctuidae)
(North-West University (South Africa), 2017)
Genetically modified (GM) Bacillus thuringiensis (Bt) Berliner (Bacillales: Bacillaceae) crops
have been adopted widely in many countries around the world due to its success in reducing
pest damage to crops and the ...
The assessment of multiple antibiotic resistant enterococci in communal and commercial cattle faecal samples and their water sources in Mafikeng, North–West Province, RSA
(2006)
Enterococcus species are found in faeces of mammals, birds, insects, reptiles, but also soil, plants and water. These bacteria can also be isolated from animal products such as milk, cheese and meat.
This study was aimed ...
Potential pathogenicity of heterotrophic plate count bacteria isolated from untreated drinking water
(2014)
Water is considered the most vital resource on earth and its quality is deteriorating. Not all
residents living in South Africa‘s rural areas have access to treated drinking water, and use
water from rivers, dams, and ...
Microbial and physico-chemical quality of groundwater in the North-West Province, South Africa
(North-West University (South Africa), 2011)
More than 80% of the North West Province's (NWP's) rural community solely depend on
groundwater for their water needs (Kalule-Sabiti & Heath, 2008). Aquifers are exposed to pollution from anthropogenic activities, yet ...
The detection and molecular characterisation of Shiga Toxigenic Escheria coli (STEC) O157 strains from humans, cattle and pigs in the North–West Province, South Africa
(2006)
The prevalence and antibiotic resistant profiles of shiga-toxin producing Escherichia
coli 0157 strains isolated from faeces samples of cattle, pigs and human stool samples
were determined. The strains were further ...
Community structure of gut microbes in Busseola fusca (Lepidoptera : Noctuidae)
(North-West University, 2015)
Bt-maize is engineered to express insecticidal toxins derived from the bacterium Bacillus thuringiensis and has been shown to be very effective against pests like Busseola fusca.However, resistance of this pest against ...
