Bacteria Bacteria is a simple one-cell plant that multiply rapidly. Classified by shape and arrangements. Types of bacteria are: Cocci. Dipplococci Streptococci. Staphylococci. Bacilli. Spirilla.

COCCI A bacteria that is round or spherical in shape Types of Cocci Diplococci- occurs in pairs Strepococci- occurs in chains Staphococci- occurs in clusters or groups

Diplococci Occurs in pairs Diseases caused: Gonorrhea Meningitis Pneumonia

Streptococci Occurs in Chains Diseases caused: Strep Throat Rheumatic Fever

Staphylococci Occurs in clusters or groups Diseases caused: Pyogenic Boils Wound infections Toxic Shock

Bacilli Bacteria that are rod shaped Bacilli-, can occur singly, pairs, or in chains. Have the ability to move due to the presence of flagella..

Bacilli, cont’d Has the ability to form spores which are difficult to kill Diseases: Tuberculosis Tetanus Pertussis Diphtheria

SPIRILLA spiral or corkscrew in shape Vibrios or corkscrew spirochete in shape Diseases caused: Syphilis Cholera

Protozoa One-celled animals Found in decayed materials or contaminated H2O Diseases caused: Malaria Amebic dysentery Trichomonas African sleeping sickness

FUNGI Simple plant-like organism Fungi-live on dead organic matter Common types: ___Yeasts molds Diseases caused: Ringworms Athlete’s foot Histoplasmosis Yeast Vaginitis Thrush

RICKETTSIAE Parasitic Microorganism Cannot live ouside of the cell of another living organism Commonly found on: Fleas Ticks Lice Mites Diseases caused: Typhus fever Rocky Mountain spotted fever

VIRUSES Diseases Caused: Smallest microorganism Common colds Measles Mumps Chickenpox Herpes Warts Influenza(flu) polio Smallest microorganism Visible only in a electron microscope Cannot reproduce unless inside another living cell Spread by blood and body secretions Difficult to kill Resistant to disinfections Resistant to antibiotics
