On cestode and digenean parasites of Clarias gariepinus (Burchell, 1822) from the Rietvlei Dam, South Africa
(Onderstepoort Journal of Veterinary Research, 2006-01-23)Sharptooth catfish, Clarias gariepinus, from the Rietvlei Dam near Pretoria, South Africa were examined for internal platyhelminth parasites. Two adult cestodes, Polyonchobothrium clarias (stomach) (prevalence 71 %, mean ... -
Diversity of metazoan parasites of the African catfish Clarias gariepinus Burchell, 1822) as indicators of pollution in a subtropical African river system
(Cambridge University Press 2009, 2009-09-18)The relationship between parasite species diversity and organic pollution in the upper Manyame catchment, Zimbabwe, was investigated between October 2006 and January 2007. The parasite assemblage comprised 13 species in ... -
Parasite hybridization in African Macrogyrodactylus spp. (Monogenea, Platyhelminthes) signals historical host distribution
(Cambridge University Press, 2010-01-21)Macrogyrodactylus spp. from the gills of Clarias gariepinus in Zimbabwe and Kenya, and C. anguillaris in Senegal were identified using haptoral sclerite morphology and by sequencing the nuclear ribosomal DNA internal ... -
Macroinvertebrate communities associated with littoral zone habitats and the influence of environmental factors in Malilangwe Reservoir, Zimbabwe
(EDP Sciences, 2012-08-07)Macroinvertebrates, diversity, Malilangwe reservoir, macrophyte cover, conductivity, water level. The aim of our study was to investigate macroinvertebrate communities so as to understand factors and processes structuring ... -
Modeling sedimentation rates of Malilangwe reservoir in the south-eastern lowveld of Zimbabwe
(Springerlink, 2012-11)Modelling the sedimentation rates using the Wallingford (2004) equations with the aid of NDVI (remote sensing) to assess land degradation was carried out for Malilangwe reservoir catchment in the south eastern lowveld of ... -
Phytochemical and analgesic activity of root crude extracts of Dicoma niccolifera wild (Asteraceae)
(Open Science Publishers, 2013-03-09)The study aimed at evaluating the phytochemical profile and anti-nociception activity of root crude extracts of D. niccolifera, a plant commonly used to alleviate painful conditions by local communities. Standard phytochemical ... -
Selected purified plant compounds as possible inhibitors of rv1819c a drug efflux pump (abc protein) from mycobacterium tuberculosis
(Ebioscholar, 2013-11-13)Multidrug-resistant tuberculosis (MDR-TB) is among the most worrisome aspects of the pandemic of antibiotic resistance because TB patients that fail treatment have a high risk of death. The active multidrug efflux pump ... -
African potato ( Hypoxis Spp): Diversity and comparison of the phytochemical profiles and cytotoxicity evaluation of four Zimbabwean species
(Open Science Publishers, 2014-01-22)The Hypoxis corm has a catalogue of medicinal uses and also serves as a source of food. Most scientific research on Hypoxis has centred on Hypoxis hemerocallidea although many other species are exploited medicinally. ... -
Pesticide management practices among rural market gardening farmers near Harare, Zimbabwe
(Academy of Science of South Africa, 2016-04-19)In 2014, we carried out a survey in Chinamhora and Chihota communal lands on the outskirts of Harare city, with the aim of understanding pesticide management practices among market gardening farmers. The farmers grew ... -
The diet of an invasive crayfish, Cherax quadricarinatus (Von Martens, 1868), in Lake Kariba, inferred using stomach content and stable isotope analyses
(Regional Euro-Asian Biological Invasions Centre (REABIC), 2018-01-27)The diet of an invasive crayfish, Cherax quadricarinatus (Von Martens 1868), in Lake Kariba, was investigated using stomach content analysis (SCA) and stable isotope analysis (SIA). The frequency of occurrence of macrophytes ...
