10 Microorganisms You Can Find in Drinking Water

Cryptosporidium

Species:• Cryptosporidium parvum, C.

andersoni, C. baileyi Significance:• Cryptosporidium is a genus

of parasites.• Cryptosporidium parvum,

may cause gastrointestinal illness.

• there is no known cure for this illness.

Anabaena sp

•a cyanobacteria that lives in freshwater reservoirs

•Anabaena bacteria have been found producing saxitoxins

•production of neurotoxins

Rotifers

• microscopic animals with about 1000 cells.

• about 2000 different species classified into three classes.

• Most rotifers are around 0.1–0.5 mm longand are common in freshwater

• act as hosts to protozoans (like cryptosporidium) and bacteria.

Escherichia coli (E. Coli)

•Escherichia coli, a bacteria that lives in, on, and around fecal matter.

•E. coli comes from human and animal wastes.

•E. coli may be washed into creeks, rivers, streams, lakes, or ground water.
