(PLOS Digital Health, 2023-06-07)The burden of HIV and related diseases have been areas of great concern pre and post the emergence of COVID-19 in Zimbabwe. Machine learning models have been used to predict the risk of diseases, including HIV accurately. ... -
Factors Associated With HIV Infection in Zimbabwe Over a Decade From 2005 to 2015: An Interval-Censoring Survival Analysis Approach
(Frontiers in Public Health, 2019-09-18)Objectives: The main objective of this study was to compare results from two approaches for estimating the effect of different factors on the risk of HIV infection and determine the best fitting model. Study design: We ... -
Estimating age specific prevalence and force of infection in Zimbabwe using combined cross-sectional surveys from 2005 to 2015
(Frontiers in epidemiology, 2022-12-06)Objective: Age structured sexual mixing patterns have been noted to be associated with HIV prevalence and force of infection. Therefore, this study aimed to estimate the age dependent HIV force of infection using survey ... -
Effect of Schistosoma haematobium infection on the cognitive functions of preschool age children and benefits of treatment from an endemic area in Zimbabwe
(BMC Infectious Diseases, 2022-10-31)Background Schistosomiasis is known to affect the cognitive functions of children, however, but there is paucity of information on its impact on early childhood development in developing countries where the disease is ... -
Chemistry of Phorbol Ester Toxicity: A Computer Modelling Approach
(2020)Phorbol esters are phytochemicals found in the Euphorbiaceae family, as the prime factors of toxicity in those plants. However, their degrees of toxicity vary from one compound to another, despite having closely similar ... -
Genetic analysis of 27 Y-Chromosome short tandem repeat (Y-STR) Loci of the Zimbabwean shona ethnic group
(2021-01)Population genetic data about modern DNA profiles, specifically for Zimbabweans, was almost non-existent aside from that of 55 individuals’ DNA profiles contributed on the YHRD international database, under accession number ... -
Differentiations in post-colonial urban spatial planning in Zimbabwe and Zambia
(2021-01)This study investigates and compares the colonial spatial planning legacies of Zimbabwe and Zambia. It examines how and why the legacies of two countries with a seemingly common colonial background would produce different ... -
In vivo toxicological study of aqueous extracts of Vitex payos fruits
(2020-08)The plant Vitex payos is used in folk medicine to treat several ailments. Despite Vitex payos’, ethno medicinal benefits, very few studies have described the fruits’ potential toxicity. The aim of the present study was to ... -
Frequency of the TP53 Codon 47 and Codon 72 polymorphisms in HIV infected women with histologically confirmed cervical and vulvar pre cancer and invasive cancer reporting at an HIV clinic in Harare, Zimbabwe
(2020-08)Cervical cancer is the most common cancer in Zimbabwean women as well as the leading cause of female cancer deaths. There has been an increase in the cervical cancer incidence of Zimbabwe from 56.2 % reported in 2012 to ... -
A bioinformatics approach to define the Eps-D1 subtelomeric chromosomal deletion in bread wheat (Triticum aestivum).
(2020-08)Flowering time is one of the critical determinants of yields in flowering plants. The flowering time in bread wheat (Triticum aestivum) is directly determined by vernalization, photoperiod response and earliness per se ... -
Gas chromatography-mass spectrometry analysis in vitro antibacterial efficacy and in silico molecular docking of compounds produced by endophytes isplated from indegenous medical plants.
(2020-08)Native medicinal plants have been traditionally used to treat various bacterial infections, fungal infections, cancers, viral infections and cardiovascular diseases. Endophytic bacteria residing inside the tissues of ... -
Antimicrobial potential of herbal creams based on extracts from Combretum zeyheri
(2021-11)Microbial resistance has become a problem in the treatment of infectious diseases and the use of plant phytochemicals has been a valuable potential source of lead compounds that can be used for sustaining human health. ... -

(2021-07)Coronavirus disease 2019 (COVID-19) is caused by a recently identified virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the disease is a pandemic. Recurrent waves of infection continue to overwhelm ... -
Use of bacteriophages to control salmonella in crocodiles and optimisation of a light induced expression system for endolysin.
(2021-08)The aims of this study were to isolate bacteriophages from crocodile feeding pen wastewater and to evaluate their effectiveness against clinical Salmonella species, Escherichia coli and Enterobacter cloacae. Also, the ... -
Isolation and identification of polystyrene-degrading bacteria from the gut of Tenebrio molitor based on the nucleotide sequence of the 16S rRNA gene
(2021-10)The excessive use of polystyrene as a packaging material has resulted in a rise in environmental pollution. Polystyrene waste has continually increased water pollution, soil pollution and the closing of landfill sites since ... -
Genetic diversity of antimicrobial resistant intestinal E.coli strains isolated from chicken produced in Chanakira village.
(2021-10)Intestinal Pathogenetic E.coli is a class of E.coli strains capable of causing an infection and subsequently disease in the intestines. This class consists of six major strains with some having their own variants, namely: ... -
