(University of Pretoria, 2019-11)Tuberculosis (TB) is a curable infectious disease, but remains a persistent scourge of mankind. It is caused by Mycobacterium tuberculosis (M. tb) that is a master of survival in the human host, where it can lie dormant ...
-
(University of Pretoria, 2019-11)Hematite (Fe2O3) is a promising photoanode material that is being studied immensely for its application in solar water splitting to produce hydrogen and oxygen as fuels. It has attractive properties such as a narrow bandgap ...
-
(University of Pretoria, 2019)The polyphagous shot hole borer (PSHB) or Euwallacea fornicatus is an ambrosia beetle, originally from South-East Asia, that can cause extensive damage, to a large variety of trees, by acting as a vector to inoculate its ...
-
(University of Pretoria, 2020-01)Ticks are considered economically significant parasitic vectors in the livestock industry globally. Vector directed vaccines are a promising method of tick control. To date only one protective antigen, Bm86, has been ...
-
(University of Pretoria, 2015)Arabidopsis thaliana is a model plant widely used to gain insights in the so called plant-pathogen interactions. This is so because plants are sessile organisms living in an environment rich in disease causing microbes. ...
-
(University of Pretoria, 2019-08)Medicinal plants play a crucial role in the healthcare treatment of many infections and also serve as the basis for the synthesis of novel chemotherapeutic agents. Included in these plants is the Tabernaemontana genus ...
-
(University of Pretoria, 2019-11)Aspergillus flavus and A. parasiticus are saprophytic storage fungi, which primarily invade maize (Zea mays) and other cereal and legume crops. Contamination of stored grains with these fungal species reduces the quality ...
-
(University of Pretoria, 2020)In developing countries, the presence and impact created by tuberculosis (TB) is alarming. With the rise of resistant TB, initiatives such as adjunct host-directed therapy (AHDT) that aim to reduce treatment time, lower ...
-
(University of Pretoria, 2019-12)The South African forestry industry largely relies on seed for its replanting programs following clear-felling. The high cost of Eucalyptus seed and planting targets makes it imperative to start with pathogen-free seeds ...

Cloning the Cercospora zeina Ecp2 effector gene for Agrobacterium-mediated transient transformation (University of Pretoria, 2019)Maize (Zea mays) is a staple crop in Africa that is under severe threat to disease by pathogenic organisms. Grey leaf spot (GLS) caused by Cercospora zeina drastically limits the yield and quality of maize produced. Not ...
-
(University of Pretoria, 2019-12)Food safety related disease outbreaks and challenges could cause serious crop and market related losses in any industry. This is also true for the commercial mushroom sector in South Africa. Disease outbreaks adversely ...
-
(University of Pretoria, 2020)Northern leaf blight (NLB) is a devastating foliar disease of maize (Zea mays L.) throughout the maize growing regions of the world. The causal agent of NLB is the hemibiotrophic fungal pathogen, Exserohilum turcicum. ...
-
