Research in the last few decades has increasingly demonstrated riverbed sediments as reservoirs of pathogenic bacteria, which could be released into water resources when sediments are resuspended. Current methods for enumerating these ...Read more
Author:Hohls, D; Du Plessis, G; Venter, SN; Steynberg, MC; De Wet, CME; Rodda, N; Kfir, RDate:1995The aim of this study was to evaluate the validity of assumptions, regarding assimilative capacity for microbial contaminants, implicit in microbial water quality management in South Africa. A one dimensional steady state stream water quality ...Read more
Author:Momba, MNB; Cloete, TE; Venter, SN; Kfir, RDate:Sep 1999Groundwater was treated with chlorine and chloramine to study the incorporation and survival of Escherichia coli (E. coli) in developing biofilms in laboratory-scale units. Membrane filter and standard spread plate procedure were used to ...Read more
Author:du Preez, MDate:Sep 2010Access to affordable, safe and sufficient quantities of water is fundamental to health and dignity of all humans. However, in 2006 an estimated 1.1 billion people still had no access to safe water and 2.6 billion lacked access to basic ...Read more
Author:Abia, ALK; Ubomba-Jaswa, Eunice; Momba, MNBDate:Oct 2015This study aimed at investigating the presence of antibiotic-resistant Escherichia coli in river bed sediments of the Apies River, Gauteng, South Africa, in order to better inform health management decisions designed to protect users of the ...Read more
Author:Motshekga, Sarah C; Ray, Suprakas SDate:Mar 2017Disinfection of bacterially-contaminated drinking water requires a robust and effective technique and can be achieved by using an appropriate disinfectant material. The advanced use of nanomaterials is observed as an alternative and effective ...Read more
Author:Abia, ALK; Ubomba-Jaswa, Eunice; Momba, MNBDate:Dec 2015Many South Africans living in resource-poor settings with little or no access to pipe-borne water still rely on rivers as alternative water sources for drinking and other purposes. The poor microbial quality of such water bodies calls for ...Read more
Author:Clasen, E; Land, Kevin J; Joubert, T-HDate:Sep 2016The presence of Escherichia coli (E. coli) is a commonly used indicator micro-organism to determine whether water is safe for human consumption. This paper discusses the design of a micro-incubator that can be applied to concentrate bacteria ...Read more
Author:Abia, ALK; Ubomba-Jaswa, Eunice; du Preez, M; Momba, MNBDate:Dec 2015Purpose
Sediments have been shown to contribute to the microbial quality of the water column during resuspension and serve as reservoirs for potentially pathogenic organisms. Currently, definitive guidelines regarding microbial indicators ...Read more
Author:Rathbone, PA; Livingstone, DJ; Calder, MMDate:1998A microbiological surveillance programme was initiated in Durban, South Africa, to provide an objective assessment of changes in the local seawater quality before and after the commissioning of two submarine outfalls in 1969 and has been ...Read more
Author:Kfir, R; Du Preez, M; Genthe, BettinaDate:1993Monoclonal antibodies (MAbs) against heat-killed Escherichia coli and Klebsiella oxytoca originating from wastewater effluent were raised in BALB/C mice. The fusion was highly successful and three hybridomas cloned were selected to study the ...Read more
