bacteria | simple one-celled organisms that multiply rapidly |
cocci | round, spherical shaped bacteria |
bacilli | rod-shaped bacteria |
streptococci | spherical shaped bacteria that appear in chains |

antibiotics | drugs that are used to treat bacterial illnesses |
protozoa | one-celled animal like microbes that live in contaminated water and decayed material |
fungi | plant-like organisms that live on dead organic matter; AKA yeasts & molds |
rickettsiae | parasitic organisms transmitted by fleas, ticks, lice, mites |
viruses | smallest microbes; spread through blood and body fluids; hard to kill; resistant to antibiotics |

reservoir | area where a causative agent can live; ideal environment for the pathogen |
fomite | any object that is contaminated with pathogens; Ex: cell phones, door knobs, desk tops, pencils |
portal of exit | The way an organism escapes from the reservoir; Ex: blood, body fluids |
mode of transmission | The way a causative agent can be transmitted to another reservoir or host; Ex: sneezes, hands, sexual contact, insects |
portal of entry | THe way a causative agent enters a new reservoir or host; Ex: break in the skin, respiratory tract |
susceptible host | a person likely to get an infection or disease usually because defenses are weakened |
contaminated | organisms are present |
asepsis | absence of disease causing pathogens |
sterie | free from all organisms, spores and viruses; free of all pathogens and nonpathogens |
