(University of Zimbabwe, 2021-06-09)
Background: Cryptococcosis is still a leading cause of mortality among patients with advanced HIV infection. Although CD4 T-cell deficiency is necessary for HIV-associated cryptococcosis, not all severely immunocompromised ...
Markers of inflammation, morbidity and mechanisms mediating resistance against Schistosoma haematobium infection in preschool age ahildren (Children aged five years and below).
(University of Zimbabwe, 2021-06-09)
Schistosomiasis is caused by a blood fluke worm of the genus Schistosoma. Adult worms can live for decades in the human host releasing ova causing inflammatory and obstructive disease in the urinary system. The preschool-age ...
Impact of climate change and biotic factors on avifauna diversity and spatial distribution in the mid-Zambezi Valley, Zimbabwe.
(University of Zimbabwe, 2021-06)
Construction of Lake Kariba on the Zambezi River restructured the biodiversity of the Zambezi Valley. However, studies on how the avian community of Kariba has changed since construction of the lake are scant. This study ...
The Taxonomy, ecology and trematode infections of gastropod snails on the northern shoreline of Lake Kariba, Zimbabwe.
(University of Zimbabwe, 2021-08)
Freshwater gastropods make up about 75% of all freshwater molluscs in the African continent. Their classification and identification have been largely based on morphological characteristics, with the main focus on shell ...
Promoter single nucleotide polymorphisms in pro-inflammatory cytokine genes in S. haematobium infected and the risk of prostate cancer development
(2021-10)
This thesis reports the findings of a thorough study to establish the role of the genetic variations in the pro-inflammatory genes and the risk of developing prostate cancer (PCa) in male individuals residing in a ...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel respiratory virus is the etiological factor of COVID-19 disease which started in the Wuhan Province, China in December of 2019. Symptoms include a dry ...
Determination of lymphocyte and cytokine profiles associated with Coronavirus disease 2019 severity
(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 ...
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 ...
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 ...
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: ...
