A sero-epidemiological survey of parasites in small stock in the north eastern region of the Free State province, South Africa
(University of the Free State, 2001)A sero-epidemiological survey was conducted in the north-eastern Free State region of South Africa to determine the parasites of veterinary importance infecting sheep and goats. Blood smears from sheep (n=37 I) and goats ... -
Development of molecular diagnostic methods (LAMP and PCR) for detection of Haemonchus contortus, fasciola spp and Trichostrongylus spp infections in livestock
(University of the Free State, 2012-12)Helminths belonging to the genera Haemonchus and Trichostrongylus as well as those of the genus Fascia/a are the causative agents of various helminthiases in animals and sometimes in humans. In both host types infections ... -
High rates of biochar soil amendment cause increased incidences of neurotoxic and oxidative stress in Eisenia fetid (oligochaeta) exposed to glyphosate
(MDPI, 2022)Despite several known beneficial attributes, biochar is suspected to cause harm to soil organisms when present in relatively high quantities in the soil. To determine the potential detrimental effects of biochar, for 96 ... -
Molecular phylogeny of South African Anopheles, Aedes and Culex (Diptera: Culicidae) based on COI, ITS2 and 28S DNA sequences
(University of the Free State, 2021-11)Mosquitoes have a substantial impact on human and animal health as vectors of disease and consequently take a heavy toll on the economy. South Africa hosts a multitude of mosquito-borne pathogens, including numerous ... -
Soil fertilization synergistically enhances the impact of pollination services in increasing seed yield of sunflower under dryland conditions
(Cambridge University Press, 2021)To exploit the potential of ecological intensification during sunflower cropping, it is crucial to understand the potential synergies between crop management and ecosystem services. We therefore examined the effect of ... -
