Cryptosporidium is a coccidian protozoan which is well-known as a ubiquitous human pathogen. Cryptosporidium begins its life cycle as sporulated oocysts, which are excreted to an external environment via the faeces of the infected host. The pathogenic oocysts reside in food and water. Transmission of Cryptosporidium takes place mainly through contact with contaminated water. The…

Stygofauna are aquatic organisms, which inhibit groundwater. Stygofauna communities are often dominated by crustacean invertebrates. This aquatic population also includes oligochaetes (worms), insects, snails and other invertebrate groups such as fish. These organisms are a great example of adaptation and ongoing evolutionary processes. Over millions of years stygofauna members developed specialised morphological and physiological adaptations.…

Coliforms are diverse group of bacteria which are used as a general indicator of faecal contamination in water sources. Coliforms are the most sensitive but least specific indicator group for faecal contamination because while many are part of the normal flora of the intestinal system of humans and other warm blooded animals, many also occur…
