References Description

[40,41] The most common types of bacteria in sewage are Enterobacteriaceae (this includes E. coli) and a range of other bacteria.
[42] Escherichia coli has a better correlation with illness in populations than faecal coliforms for fresh waters but not marine environments
[43] Domestic wastewater contains a variety of disease-causing bacteria, viruses, protozoa and helminths.
[44] The survival times in days were considered for bacteria, protozoa, helminths and viruses.
[9] Pathogenic organisms in excreta include bacteria, helminths, trematodes, protozoa and viruses.
[9] Water quality monitoring parameters for the use of wastewater in agriculture and aquaculture are based on acceptable levels of E coli.
[2] The pathogens in human effluent are bacteria, protozoa, helminths and viruses.
[2,45] Faecal coliforms are a good indicator of water that is unsafe to drink.
[45] But faecal coliforms “are less effective as indicators of excreted viruses, and of very limited use for protozoa and helminths for which no
reliable indicators exist”.
[31] Many types of viruses.
[46] “Waterborne infections are caused by infectious agents belonging to three broad groups: bacteria, parasites (protozoa and helminths) and
viruses”.
[20] There are two groups of wastewater-related diseases: (1) Viral (rotavirus), bacterial (Campylobacter), protozoa (amoeba, Cryptosporidium) and (2) diseases caused by Helminths’ eggs (eg Ascaris).
