Legionella

Legionella
The genus Legionella includes 26 species of which L. pneumophilia is most frequently associated with human disease. Legionella spp. are known to infect humans by inhalation. The ingestion of drinking water containing Legionella is considered irrelevant until the bacteria are amplified by multiplying in specific sites under thermal enrichment. Therefore, hot-water systems maintained below 60oC,…

Cryptosporidium

Cryptosporidium
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…

Pseudomonas aeruginosa

Pseudomonas aeruginosa
Pseudomonas aeruginosa is a free-living pathogen commonly found in soil and water. It often multiplies in an enriched aquatic environment. The presence of the bacteria in drinking water may indicate a serious impairment of the water treatment system. Therefore, its presence can be used to evaluate the general cleanliness and quality of water. P. aeruginosa…

Stygofauna

Stygofauna
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.…
