    The Potential of Sub-Saharan African Plants in the Management of Human Immunodeficiency Virus Infections: A Review.

    Phytotherapy research : PTR 29(10) 1452-87.

    Acquired immunodeficiency syndrome, caused by human immunodeficiency virus (HIV), is a leading cause of mortality and morbidity in Sub-Saharan Africa, particularly in Southern Africa. Phytomedicines are an integral part of African health care. The Southern African flora is composed of at least 23 400 taxa. Despite this richness, only a handful of botanical products have been assessed for activities against HIV. This study aimed to summarize the potential of Sub-Saharan African plants, based on their composition and the established bioactivities, as sources of agents to manage HIV symptoms and as retroviral therapy. At least 109 plant species from 42 families and 94 genera that are found in Southern Africa were shown to have potential or actual activities against HIV. Only 12 of these plant species from 6 families and 10 genera were shown to harbour anti-HIV properties. Phytochemicals that include β-sitosterols, terpenoids, glycosides, saponins, flavonoids, triterpenoids, tannins and alkaloids, which harbour anti-HIV properties, were found to have a near cosmopolitan presence across the plant families in the region. Bioactivities of multiple phytochemicals are comparable to those for standard allopathic antiretroviral drugs. Research to determine the anti-HIV activities of the identified and other plants, including clinical trials, is long overdue. Copyright © 2015 John Wiley & Sons, Ltd.

    Modelled habitat suitability of a malaria causing vector (Anopheles arabiensis) relates well with human malaria incidences in Zimbabwe

    Applied Geography 60 130-138.

    Accurate modelling of the geographic distribution of disease vectors is an important step towards developing strategies for effective control of vector borne diseases. In this study, we used maximum entropy (Maxent) to develop a spatially explicit model to predict the habitat of a malaria causing vector, Anopheles arabiensis, based on key environmental factors. Our results show that altitude combined with isothermality, temperature seasonality, annual precipitation and precipitation of the wettest month can be used to successfully model habitat suitability of A. arabiensis. Based on these five key factors, our results show that areas that are highly suitable for A. arabiensis are generally in the north, northeast, south and south eastern parts of Zimbabwe. In fact, our results show that all the five factors had AUC values ≥70% which is classified as good for predictive purposes. The results of our Maxent model overall show AUC values of 0.84 for training and 0.88 for test data. In addition, our results also show that the habitat suitability model positively correlated (p < 0.05) with malaria incidences recorded at health facilities for the period 1974–1981 and the years 1996, 1997, 1998 and 1999 although the correlations are weak. Our results suggest that A. arabiensis habitat suitability can be used as an indicator of malaria incidences.

    Anticandidial properties and some mammalian toxicity profile of Lampranthus francisci

    Journal of Mycology.

    Fungal infections have been rising due to the increasing number of immunocompromised patients and intensive use of some antifungal agents. Lampranthus francisci is an ornamental succulent plant. In Zimbabwe, the fresh sap from the leaves is used to treat fungal scalp infections. The activity of L. francisci fresh and dry acetone, ethanol, hydroethanolic and aqueous extracts against Candida albicans and Candida krusei was determined. Mouse peritoneal cavity cells and sheep red blood cells were used to investigate L. francisci’s toxicity profile. The hydroethanolic extracts were the most effective extracts against C. albicans. The fresh ethanol extract was the most effective extract against C. krusei. The dry acetone extract, dry ethanol extract and the fresh and dry aqueous extracts promoted the growth of C. krusei. The hydroethanolic extracts caused haemolysis of sheep cells. The hydroethanolic extracts promoted the growth of the mouse peritoneal cavity red blood cells. Both aqueous extracts increased the density of the mouse cells, but only the fresh extract increased the metabolism of the mouse cells. L. francisci has some fungicidal activity and boosts the growth of immune cells, thus, validating its use in ethnomedicine. L. francisci extracts are potential leads for the isolation of immune stimulatory compounds.
