3.  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.

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

5.  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.

6.  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.

7.  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

8.  Morphology bacteria  Has a characteristic sweet odor  Gram negative bacteria

9.  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.
