TL;DR: The microbial quality of several, untreated surface water sources used by rural communities in the Venda region of South Africa was assessed to determine its safety for human consumption and to highlight the possible occurrence of water-borne diseases.

TL;DR: The circulating rotav virus types observed in this study add to the knowledge of the natural history of rotavirus infection and provide the groundwork to consider future vaccine strategies.

TL;DR: Although improved sources generally delivered ‘safe’ water at the point-of-supply, 12% of source samples were contaminated and as such were ‘unsafe’ in household storage, and this significant deterioration in microbial quality of water from improved sources was seen in both countries.

TL;DR: The volatile oil of Lippia javanica was prepared by hydrodistillation of leaves, flowers and stems, and characterized by GC-MS, and found to inhibit E. coli and S. aureus at 1% dilution and be active against Plasmodium falciparum.

TL;DR: River water sources and diarrhoeic stools of residents in the Venda Region, Limpopo Province of South Africa were analysed for the prevalence of Escherichia coli and the presence of virulence genes among the isolates, revealing a possibility of a recycling of pathogenic E. coli strains, particularly the EPEC and NEC strains, between the water sources
