    Diverse norovirus genotypes identified in sewage-polluted river water in South Africa
    10 Apr 2013

    This study aimed to assess norovirus (NoV) contamination and genotype diversity in surface water in Gauteng, South Africa. Between January 2008 and December 2010, three rivers, namely Klip, Suikerbosrant, and Rietspruit were monitored for NoV genogroup (G)I and GII. Viruses were recovered using the glass wool adsorption-elution technique and detected by real-time reverse transcription–polymer…

    Seroprevalence and risk factors for Toxoplasma gondii in sheep in Grosseto district, Tuscany, Italy
    02 May 2013

    BACKGROUND: Serum samples from 630 milk sheep, in 33 dairy flocks representative of the southern area of the Tuscany region, were tested for the presence of antibodies to Toxoplasma gondii using an indirect immunofluorescence antibody test (IFAT). Questionnaires exploring the management system were completed by the veterinarian in charge of the flocks. RESULTS: At least one seropositive anima…

    Clinical features of oral cancer
    08 Jul 2013

    Oral cancer (OC) is a major cause of global morbidity and mortality. Squamous cell carcinoma accounts for more than 90% of oral malignancies and occurs most frequently in middle-aged to elderly patients who smoke and drink heavily. The overall outlook for patients diagnosed with oral squamous cell carcinoma (OSCC) remains poor, largely due to late clinical presentation. Early lesions are frequen…

    Salinity of irrigation water in the Philippi farming area of the Cape Flats, Cape Town, South Africa
    11 Sep 2013

    This paper explores the nature, source and spatial variation of the salinity of water used for irrigation in a coastal urban farming area in Cape Town, South Africa, where water from the Cape Flats aquifer is drawn into storage ponds and used for crop irrigation. Water samples were collected in summer and winter from selected sites across the study area and were analysed for salinity as well as f…

    Assessment of microbial contamination of groundwater in upper Limphasa River catchment, located in a rural area of northern Malawi
    11 Sep 2013

    In rural Africa, scientific evidence is often lacking to guide the scaling-up of groundwater as the safest source of potable water. An investigation was conducted in the Upper Limphasa Catchment in northern Malawi to determine the safety of groundwater sources and to explore factors influencing water quality. Water samples from 17 boreholes, 6 hand-dug wells and 90 households were analysed for se…

    Sustainable groundwater use, the capture principle, and adaptive management
    10 Oct 2013

    The purpose of this paper is to review the case for using ‘capture’ rather than recharge as the conceptual basis for sustainable groundwater use in South Africa. Capture refers to the sum of the increase in recharge and decrease in discharge brought about by pumping. Definitions of sustainability are reviewed, and the capture process is outlined. Implications for using the capture principle in th…

    Realising the right of access to water: pipe dream or watershed?
    17 Sep 2014

    The article assesses the implications of the Grootboom judgment on the right of access to water. The free basic water policy intends six free kilolitres of water per household per month to be funded from the equitable share and internal cross-subsidies. No additional funds are available for the provision of free water. This creates serious problems in rural communities that do not have sufficient…

    Identifying ecosystem service hotspots for environmental management in Durban, South Africa
    26 Jan 2017

    Background: Despite considerable research into the importance of ecosystem services, little has been achieved in translating such research into management action. In an urban context where numerous pressures on ecosystem services exist, the identification and management of priority ecosystem services areas are vital to ensure the ongoing provision of these services. Method: To identify opportunit…

    Fluoride concentration in drinking water in small villages in the Cape province [Die fluoriedkonsentrasie in die drinkwater van kleiner dorpe in die Kaapprovinsie.]
    15 May 2011

    The purpose of the study was to update existing tables on the fluoride content of drinking water and thereby help curb its fluoride overdose from the use of fluoride containing tablets. The fluoride concentration in the drinking water of 57 villages in the Cape Province was determined by a combination fluoride ion selective electrode. This investigation showed that the number of available water s…
