The IMBM Brochure (2009) provides a summary of the staffing, activities and outputs of the Institute for the 2009 academic year
Characterisation of the arsenic resistance genes in Bacillus sp. UWC isolated from maturing fly ash acid mine drainage neutralised solids
(Academy of Science of South Africa, 2010)
An arsenic resistant Bacillus sp. UWC was isolated from fly ash acid mine drainage (FA-AMD) neutralised solids. A genomic library was prepared and screened in an arsenic sensitive mutant Escherichia coli strain for the ...
Molecular characterization of the 16S rRNA Gene of helicobacter fennelliae isolated from stools and blood cultures from paediatric patients in South Africa
Forty strains of H. fennelliae collected from paediatric blood and stool samples over an 18 year period at a children's hospital in Cape Town, South Africa, were amplified by PCR of the 16S rRNA. Two distinct genotypes of ...
A designed experiments approach to optimizing MALDI-TOF MS spectrum processing parameters enhances detection of antibiotic resistance in Campylobacter jejuni
(Frontiers Media, 2016)
MALDI-TOF MS has been utilized as a reliable and rapid tool for microbial fingerprinting at the genus and species levels. Recently, there has been keen interest in using MALDI-TOF MS beyond the genus and species levels to ...
Multilocus sequence typing methods for the emerging Campylobacter species C. hyointestinalis, C. lanienae, C. sputorum, C. concisus, and C. curvus
(Frontiers Media, 2012)
Multilocus sequence typing (MLST) systems have been reported previously for multiple food - and food animal-associated Campylobacter species (e.g., C. jejuni, C. coli, C. lari, and C. fetus) to both differentiate strains ...
Characterisation of campylobacter concisus strains from South Africa using amplified fragment length polymorphism (AFLP) profiling and a genomospecies-specific polymerase chain reaction (PCR) assay: Identification of novel genomospecies and correlation with clinical data
(Academic Journals, 2013)
Amplified Fragment Length Polymorphism (AFLP) profiling was used to evaluate the distribution of phenotypically indistinguishable, but genetically distinct, among Campylobacter concisus strains from South Africa. A Polymerase ...
Virome assembly and annotation: A surprise in the Namib Desert
(Frontiers Research Foundation, 2017)
Sequencing, assembly, and annotation of environmental virome samples is challenging. Methodological biases and differences in species abundance result in fragmentary read coverage; sequence reconstruction is further ...
High-level diversity of tailed phages, eukaryote-associated viruses, and virophage-like elements in the metaviromes of Antarctic soils
(American Society for Microbiology, 2014)
The metaviromes of two distinct Antarctic hyperarid desert soil communities have been characterized. Hypolithic communities, cyanobacterium-dominated assemblages situated on the ventral surfaces of quartz pebbles embedded ...
Micro-Eukaryotic diversity in Hypolithons from Miers Valley, Antarctica
(Multidisciplinary Digital Publishing Institute (MDPI), 2013)
The discovery of extensive and complex hypolithic communities in both cold and hot deserts has raised many questions regarding their ecology, biodiversity and relevance in terms of regional productivity. However, most ...
Structure and functional characterization of pyruvate decarboxylase from Gluconacetobacter diazotrophicus
(BioMed Central, 2014)
BACKGROUND: Bacterial pyruvate decarboxylases (PDC) are rare. Their role in ethanol production and in bacterially mediated ethanologenic processes has, however, ensured a continued and growing interest. PDCs from ...
