S&S: cough, chest pain, chills, fever

Causes: bacteria, fungus, virus, chemicals

• simple one-celled organisms
• MOST ABUNDANT PATHOGENS
• good and bad varieties
• most easily destroyed by antibodies
• cause infection by releasing toxins (cause of many deadly diseases)

a round bacterium, usually found in chain formation

GROUP A: "strep throat"

GROUP B: can cause illness in babies, elderly, and immunocompromised; ear infections

pneumonia

bacterial infection of respiratory system

• chronic bloody cough
• estimated 1/3 of world infected
• multidrug resistant strain
• extensively drug resistant strain

• typhus, rocky mountain spotted fever
• lyme disease

used to treat bacterial infections ONLY!!

• 1/3 of prescriptions necessary?
• bacteria evolve over time
• overuse of antibiotics in food
• possible overuse of antibacterial soaps

smallest and most difficult to get rid of, need cells from host (you) to multiply and obtain energy

EX: common cold, flu, mono, hepatitis, mumps, herpes, measles and rubella, rabies

(can be days or years)
