Insecticide resistance in the malaria vector Anopheles arabiensis in Mamfene, KwaZulu-Natal

South African Journal of Science, 2015
The control of malaria vector mosquitoes in South Africa’s affected provinces is primarily based on indoor spraying of long-lasting residual insecticides. The primary vectors in South Africa are Anopheles arabiensis and An. funestus.

Detection of virulence factors and beta-lactamase encoding genes among the clinical isolates of Pseudomonas aeruginosa [PDF]

International Journal of Pharmaceutical Research, 2019, 2019
Background: Pseudomonas aeruginosa has emerged as a significant opportunistic bacterial pathogen that causes nosocomial infections in healthcare settings resulting in treatment failure throughout the world. This study was carried out to compare the relatedness between virulence characteristics and \b{eta}-lactamase encoding genes producing Pseudomonas ...

Novel Approaches To Design Glycan‐Based Antibacterial Inhibitors

European Journal of Organic Chemistry, Volume 26, Issue 1, January 2, 2023., 2023
Sweet and sticky: This review describes recent advances in the synthesis and application of homo‐and heterovalent glycan‐scaffolds as potential candidates for efficient bacteria lectin inhibition. To study and address the many complex molecular mechanisms involved in multivalent lectin binding events, novel glycoconjugate designs and fine‐tunable ...

A Systemic Receptor Network Triggered by Human cytomegalovirus Entry [PDF]

Advances in Virology Volume 2011 (2011), Article ID 262080, 11 pages, 2010
Virus entry is a multistep process that triggers a variety of cellular pathways interconnecting into a complex network, yet the molecular complexity of this network remains largely unsolved. Here, by employing systems biology approach, we reveal a systemic virus-entry network initiated by human cytomegalovirus (HCMV), a widespread opportunistic ...

Staphylococcus aureus bacteraemia in Gauteng academic hospitals, South Africa

International Journal of Infectious Diseases, 2015
Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) infections are responsible for longer hospital stays, increased hospital costs, and poorer outcomes compared to methicillin-sensitive S. aureus (MSSA) infections.

Early initiation of fast‐track care for persons living with HIV initiating dolutegravir‐based regimens during a period of severe civil unrest in Port‐au‐Prince, Haiti: a pilot randomized trial

Journal of the International AIDS Society
Introduction Differentiated service delivery (DSD) models have been widely implemented for patients in stable HIV care. However, DSD has rarely been offered to newly diagnosed patients.

Comparative study of adenosine 3′‐pyrophosphokinase domains of MuF polymorphic toxins

FEBS Open Bio, EarlyView.
With the ultimate goal of understanding the association of toxin‐immunity modules to temperate phages, we characterized toxins from three prophages and examined cross‐protection from immunity proteins. The toxins exhibit adenosine 3′‐pyrophosphokinase activity and are toxic in Escherichia coli.

Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota

Angewandte Chemie, EarlyView.
Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...
