Microbial Cysts

Microbial cysts

Both giardia and cryptosporidium are microbial cysts and they are tough to disinfect. What makes them tough is the way they operate. These microbes grow a cyst wall around themselves for protection in unfavourable conditions. When giardia and cryptosporidium reach more favourable environments like your stomach, their cyst walls break down and the microbes inside them release to potentially cause gastrointestinal illness like diarrhoea, nausea and stomach cramps. According to the EPA, cryptosporidium is resistant to disinfection.

These are microbial cysts found in water and their effects on your health:

  • Cryptosporidium

Cryptosporidium is a microbial cyst that is commonly found in lakes and rivers that can cause gastrointestinal illness. It enters the water through animal and human faecal matter.


  • Giardia

The microbial cyst, Giardia, is a one-celled parasite that infects humans and animals in the cyst stage of their life cycle. It enters the water through animal and human faecal matter.
