Indicators of river water microorganisms is a group of microorganisms that are used as a hint of river water quality.

Water microorganisms are capable of flourishing in all water habitants, three major domain compose water microorganisms Eukaryota,Archae, and Bacteria , as well as viruses.

MICROORGANISMS IN THE RIVER WATER

BACTERIAL- Cyanobacteria- Yersinia enterocolicita - E. coli and Streptococci- Pseudomonas aureginosa

Morphology of bacteria Also known as blue-

green bacteria Photosynthetic bacteria Gram negative Causing convulsions,

bloody diarrhea and sudden death in affected animals

produce taste and odor compounds.

Coccobacillus shaped Gram negative can be transmitted to

animals and humans in heavily contaminated river water.

Symptoms of infection include fever, abdominal pain, and bloody diarrhea.

E. Coli

Streptococci

Can enter a river system are through livestock waste, faulty sewage system

Pathogen bacteria Can cause rheumatic

fever; acute glomerulonephritis (kidney disease); scarlet fever; bacteria sepsis, called Bacteremia; and toxic-shock syndrome

Morphology bacteria Has a characteristic

sweet odor Gram negative

bacteria

CONCLUSION

The microbes that can be used as indicators of river water microorganisms are Cyanobacteria, Yersinia enterocolicita, E. coli and Streptococci, Pseudomonas aureginosa.

Most of microbes in the river water are pathogen.

The microbes can enter to river system through livestock waste, urban run-off, and faulty sewage system.
