INTRODUCTION • 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
CYANOBACTERIA • Morphology of bacteria • Also known as blue-green bacteria • Photosynthetic bacteria • Gram negative • Causing convulsions, bloody diarrhea and sudden death in affected animals • produce tasteandodor compounds.
YERSINIA ENTEROCOLICITA BACTERIA • Coccobacillus shaped • Gram negative • canbe transmitted to animals and humans in heavilycontaminated river water. • Symptoms of infection include fever, abdominal pain, and bloody diarrhea.
Bacteria Escherichia coli and Streptococci • E. Coli • Streptococci • Can enter a river system are through livestock waste, faulty sewage system • Pathogen bacteria • Can cause rheumaticfever; acute glomerulonephritis (kidney disease);scarlet fever; bacteria sepsis, called Bacteremia; and toxic-shock syndrome
Pseudomonas aeruginosa • 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.
