Analytical studies of antimicrobial peptides as diagnostic biomarkers for the detection of bacterial and viral Pneumonia
(MDPI, 2022)Pneumonia remains one of the leading causes of infectious mortality and significant economic losses among our growing population. The lack of specific biomarkers for correct and timely diagnosis to detect patients’ status ... -
Antimicrobial activities of a novel biflavonoid and other constituents from Rhus natalensis
(Academic Journals, 2013)Phytochemical studies on Rhus natalensis root bark collected from Kenya led to the isolation and identification of a new biflavonoid (3-(1-(2,4-dihydroxyphenyl)-3,3-bis(4-hydroxyphenyl)-1-oxopropan-2- yl)-7-methoxy-4H-ch ... -
Biodiversity: so much more than legs and leaves
(AOSIS OpenJournals, 2013)Microorganisms inhabit virtually every possible niche on Earth, including those at the outer envelope of survival. However, the focus of most conservation authorities and ecologists is the ‘legs and leaves’ side of biology ... -
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 ... -
Degradation of hydrocarbons and heavy metal reduction by marine bacteria in highly contaminated sediments
(MDPI, 2020)Investigations on the ability of bacteria to enhance removal of hydrocarbons and reduce heavy metal toxicity in sediments are necessary to design more effective bioremediation strategies. In this study, five bacterial ... -
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 ... -
Designing novel possible kinase inhibitor derivatives as therapeutics against Mycobacterium tuberculosis: An in silico study
(Scientific Reports, 2019)Rv2984 is one of the polyphosphate kinases present in Mycobacterium tuberculosis involved in the catalytic synthesis of inorganic polyphosphate, which plays an essential role in bacterial virulence and drug resistance. ... -
Genome sequence of an alkaliphilus species isolated from historically contaminated sediments of the gulf of Naples (Mediterranean Sea)
(American Society for Microbiology, 2021)Here, we report the draft genome sequence of a metagenome-assembled genome (MAG) of a new Alkaliphilus bacterium, NP8, of the Clostridiaceae family. This bacterium was isolated from polluted sediment collected from an ... -
Hypolithic and soil microbial community assembly along an aridity gradient in the Namib Desert
(Springer, 2013)The Namib Dessert is considered the oldest desert in the world and hyperarid for the last 5 million years. However, the environmental buffering provided by quartz and other translucent rocks supports extensive hypolithic ... -
Identification of biomarkers for the accurate and sensitive diagnosis of three bacterial pneumonia pathogens using in silico approaches
(Springer Nature, 2020): Pneumonia ranks as one of the main infectious sources of mortality among kids under 5 years of age, killing 2500 a day; late research has additionally demonstrated that mortality is higher in the elderly. A few ... -
An in-vitro analysis of the antimicrobial efficacy of herbal toothpastes on selected primary plaque colonizers
(iMD Publishers, 2011)Plaque associated oral disease affects a considerable portion of the population and is considered one of the major causes of tooth loss. In most cases toothbrushing only removes a limited amount of dental plaque and other ... -
The Microbial Aetiology of Periodontal Diseases
(InTech, 2012)Introduction: The study of the aetiology of periodontal diseases has continued for decades with much progress shown in the last two decades. Having moved through periods of “whole” plaque (with emphasis on mass) being ... -
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 ... -
Phytochemical screening and biological activity studies of five South African indigenous medicinal plants
(Academic Journals, 2010)Different extracts and fractions of five selected indigenous South African medicinal plants, namely, Cissampelos capensis, Geranium incanum and three Gethyllis species, were subjected to phytochemical screening and testing ... -
Review and re-analysis of domain-specific 16S primers
(Elsevier, 2003)The Polymerase Chain Reaction (PCR) has facilitated the detection of unculturable microorganisms in virtually any environmental source and has thus been used extensively in the assessment of environmental microbial diversity. ... -
Transcriptomic profile of mycobacterium smegmatis in response to an imidazo[1,2-b][1,2,4,5]tetrazine reveals its possible impact on iron metabolism
(Frontiers Media, 2021)Tuberculosis (TB), caused by the Mycobacterium tuberculosis complex bacteria, is one of the most pressing health problems. The development of new drugs and new therapeutic regimens effective against the pathogen is one ...
