Antibiotic resistance, efflux pump genes and virulence determinants in Enterococcus spp. from surface water systems
Molale, L.G.; Bezuidenhout, Cornelius Carlos (Springer, 2016)The aim of this study was to report on antibiotic susceptibility patterns as well as highlight the presence of efflux pump genes and virulence genetic determinants in Enterococcus spp. isolated from South African surface ... -
Global distribution and current research of AmpC beta-lactamase genes in aquatic environments: a systematic review
Coertze, Roelof Dirk; Bezuidenhout, Cornelius Carlos (Elsevier, 2019)AmpC beta-lactamase genes are some of the most common antibiotic resistance genes and require special attention once they have become mobilised. The detection of these genes is well documented in clinical settings. However, ... -
Gut microbiota of Busseola fusca (Lepidoptera: Noctuidae)
Snyman, Maxi; Gupta, Arvind Kumar; Bezuidenhout, Cornelius Carlos; Claassens, Sarina; Van den Berg, Johnnie (Springer, 2016)Busseola fusca (Fuller) (Lepidoptera: Noctuidae) is a stemborer pest that attacks maize (Zea mays) throughout sub-Saharan Africa. Genetically modified maize has been shown to be effective against B. fusca. However, resistance ... -
Heavy metal tolerance potential of Aspergillus strains isolated from mining sites
Oladipo, Oluwatosin Gbemisola; Ezeokoli, Obinna Tobechukwu; Maboeta, Mark Steve; Bezuidenhout, Cornelius Carlos; Awotoye, Olusegun Olufemi; Olayinka, Akin (Taylor & Francis, 2016)Increased heavy metal pollution generated through anthropogenic activities into the environment has necessitated the need for eco-friendly remediation strategies such as mycoremediation. With a view to prospecting for fungi ... -
Heavy metal tolerance traits of filamentous fungi isolated from gold and gemstone mining sites
Oladipo, Oluwatosin Gbemisola; Bezuidenhout, Cornelius Carlos; Maboeta, Mark Steve; Awotoye, Olusegun Olufemi; Olayinka, Akinyemi (Sociedade Brasileira de Microbiologia, 2018)tIncreased environmental pollution has necessitated the need for eco-friendly clean-upstrategies. Filamentous fungal species from gold and gemstone mine site soils were iso-lated, identified and assessed for their tolerance ... -
PCR-denaturing gradient gel electrophoresis analysis of microbial community in soy-daddawa, a Nigerian fermented soybean (Glycine max (L.) Merr.) condiment
Ezeokoli, Obinna T.; Gupta, Arvind K.; Mienie, Charlotte; Bezuidenhout, Cornelius C.; Popoola, Temitope O.S. (Elsevier, 2016)Soy-daddawa, a fermented soybean (Glycine max (L.) Merr.) condiment, plays a significant role in the culinary practice of West Africa. It is essential to understand the microbial community of soy-daddawa for a successful ... -
The prevalence and diversity of AmpC β-lactamase genes in plasmids from aquatic systems
Coertze, Roelof Dirk; Bezuidenhout, Cornelius Carlos (IWA Publishing, 2018)This study aimed to investigate the presence and diversity of AmpC β-lactamase and integrase genes among DNA (genomic and plasmid) from bacterial populations in selected aquatic systems. Following an enrichment step, DNA ... -
Spatial and temporal variations in pollution indicator bacteria in the lower Vaal River, South Africa
Chidamba, Lizyben; Cilliers, Elrina; Bezuidenhout, Cornelius Carlos (Water Environment Federation, 2016)The aim of this study was to evaluate the spatial and temporal variation of microbiological parameters of the Lower Vaal River, with emphasis on the Staphylococci population. River water concentrations of Staphylococci, ... -
Tolerance and growth kinetics of bacteria isolated from gold and gemstone mining sites in response to heavy metal concentrations
Oladipo, Oluwatosin Gbemisola; Ezeokoli, Obinna Tobechukwu; Maboeta, Mark Steve; Bezuidenhout, Jacobus Johannes; Tiedt, Louwrens R.; Jordaan, Anine; Bezuidenhout, Cornelius Carlos (Elsevier, 2018)Response and growth kinetics of microbes in contaminated medium are useful indices for the screening and selection of tolerant species for eco-friendly bio-augmentative remediation of polluted environments. In this study, ... -
Transcriptome and differentially expressed genes of Busseola fusca (Lepidoptera: Noctuidae) larvae challenged with Cry1Ab toxin
Peterson, Bianca; Sanko, Tomasz Janusz; Bezuidenhout, Cornelius Carlos; Van den Berg, Johnnie (Elsevier, 2019)Busseola fusca (Fuller) (Lepidoptera: Noctuidae), a major insect pest of maize in sub-Saharan Africa, has de-veloped high levels of non-recessive resistance to Cry1Ab toxin expressed in genetically modified Bt maize.Multiple ... -
Virulence determinants and production of extracellular enzymes in Enterococcus spp. from surface water sources
Molale, Lesego Gertrude; Bezuidenhout, Cornelius Carlos (IWA Publishing, 2016)Virulence factors in Enterococcus may be indicative of potential pathogenicity. The aim of this study was to determine the relationship between the presence of clinically relevant virulence genes, in Enterococcus spp. from ...
