Association between clinical and environmental factors and the gut microbiota profiles in young South African children
(Nature Research (part of Springer Nature), 2021)ENGLISH ABSTRACT: Differences in the microbiota in populations over age and geographical locations complicate cross-study comparisons, and it is therefore essential to describe the baseline or control microbiota in each ... -
Optimizing antibiotic prescribing : collective approaches to managing a common-pool resource
(Wiley, 2019)Background: Antimicrobial resistance (AMR) is one of the greatest threats in 21st century medicine. AMR has been characterized as a social dilemma. A familiar version describes the situation in which a collective resource ... -
Bedaquiline, moxifloxacin, pretomanid, and pyrazinamide during the first 8 weeks of treatment of patients with drug-susceptible or drug-resistant pulmonary tuberculosis: a multicentre, open-label, partially randomised, phase 2b trial
(Elsevier, 2019)Background: New anti-tuberculosis regimens that are shorter, simpler, and less toxic than those that are currently available are needed as part of the global effort to address the tuberculosis epidemic. We aimed to investigate ... -
Carbapenemase-producing Enterobacteriaceae colonisation in adult inpatients : a point prevalence study
(AOSIS, 2019)Background: Infections caused by carbapenemase-producing Enterobacteriaceae (CPE) have been increasing worldwide in recent years, but data regarding the prevalence and clinical significance of CPE colonisation in South ... -
Clonal expansion of colistin-resistant Acinetobacter baumannii isolates in Cape Town, South Africa

Carriage of colistin-resistant Gram-negative bacteria in children from communities in Cape Town (Tuberculosis child multidrug-resistant preventive therapy trial sub-study)
(AOSIS, 2021)ENGLISH ABSTRACT: Colistin is a last-resort antibiotic against multidrug-resistant, Gram-negative bacteria. Colistin resistance has been described in the clinical settings in South Africa. However, information on carriage ... -
Characterisation of mcr-4.3 in a colistin-resistant Acinetobacter nosocomialis clinical isolate from Cape Town, South Africa
(Elsevier, 2021)Objectives: Colistin resistance in Acinetobacter spp. is increasing, resulting in potentially untreatable noso- comial infections. Plasmid-mediated colistin resistance is of particular concern due to its low fitness cost ... -
Characterisation of mobile colistin resistance genes (mcr‑3 and mcr‑5) in river and storm water in regions of the Western Cape of South Africa
(BMC (part of Springer Nature), 2021)Background: Colistin is regarded as a last-resort antimicrobial against multi-drug resistant Gram-negative bacteria (GNB), therefore the dissemination of colistin resistance in the environment is of great concern. Horizontal ... -
Bacterial infection, antibiotic use and COVID-19 : lessons from the intensive care unit
(Health & Medical Publishing Group, 2021-04-14)Background. Empirical broad-spectrum antibiotics are frequently prescribed to patients with severe COVID-19, motivated by concern about bacterial coinfection. There is no evidence of benefit from such a strategy, while the ... -
