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 ...
Phenotypic and biochemical characterisation of the causal agent of bacterial leaf streak of maize
(North-West University, 2015)
Maize is the staple food for a majority of people in Southern Africa, but plant diseases are responsible for at least 10% of crop production losses. Bacterial leaf streak (BLS) of maize was first reported in South Africa ...
DNA barcoding of different earthworms' species and their response to ecotoxicological testing
(North-West University, 2015)
The ecotoxicological literature reveals that countless researchers worldwide rely upon informally identified commercial earthworm stocks for laboratory bioassays. The primary aim of this study was to investigate laboratory ...
The role of gut microbes on the efficacy of Bt maize against lepidopteran stem borers
(North-West University, 2015)
The evolution of pest resistance to Cry proteins threatens the long-term use of Bt crops. Busseola fusca developed resistance to Bt maize in South Africa but the mechanism of resistance is not well understood. According ...
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 ...
Molecular characterisation of the causal agent of bacterial leaf streak of maize
(North-West University, 2015)
All members of the genus Xanthomonas are considered to be plant pathogenic, with specific pathovars infecting several high value agricultural crops. One of these pathovars, X. campestris pv. zeae (as this is only a proposed ...
Molecular profiling of microbial population dynamics in environmental water
(North-West University, 2015)
Increasing socio-economic growth and development of South Africa’s freshwater systems require continuous augmentation of water sources to meet the growing water requirements of communities and industries. Anthropogenic ...
