| Question | Answer |
|---|---|
| Disease producing organisms | Pathogens |
| Infection restricted to a small area | Localized infection |
| Widespread infection | Systemic infection |
| Chemicals used to treat bacterial infections | Antibiotics |
| A disease that can be spread from one host to another | Communicable disease |
| A disease acquired by many people in a given area over a short time period | Epidemic disease |
| A worldwide epidemic | Pandemic |
| The study of the occurrence and distribution of diseases in a population | Epidemiology |
| Time from exposure to a pathogen until development of symptoms | Incubation period |
| Bacteria that live on/in our bodies but generally do not cause disease | Normal flora |
| A hospital–acquired infection | Nosocomial infection |
| A continual source of infection living or nonliving | Reservoir of infection |
| The ability to ward off disease | Resistance |
| A process that destroys all living organisms and their spores | Sterilization |
| A carrier of pathogens from host to host | Vector |
| A round shaped bacteria | Coccus |
| A rod shaped bacteria | Bacillus |
| Round bacteria in chains | Streptococci |
| Round bacteria in clusters | Staphylococci |
| A bacteria that is a curved rod and causes severe diarrhea | Vibrio cholerae |
| The organism that causes syphillis | Treponema pallidum |
| The bacterial cell is surrounded by these two structures | Cell wall & cell membrane |
| Some bacteria form these structures that allow them to survive in a harsh environment | Spores |
| These two types of bacteria are smaller than most and must live within the cells of the host | Rickettsia and Chlamydia |
| The smallest of infectious agents | Viruses |
| Examples of viral diseases | Mumps, measles, influenza, poliomyelitis, AIDS |

| Parasites that live inside the body | Endoparasites |
| The person or organism that is infected by a pathogen causing infection | Host |
| A staining procedure done to identify bacteria that results in purple/blue and pink/red organisms | Gram stain |
| Gram+ is what color | Purple/blue |
| Gram– is what color | Pink/red |
| Stain used to identify tuberculosis organisms | Acid–fast stain |
| The growth of pathogens in a media is called a _________ | Culture |
| Culture and sensitivity test is ___________ | Growing bacteria and seeing which antibiotics will kill them |
| The ways in which bacteria gain access to our bodies by the respiratory, GI, GU tract is called __________ | Portals of entry |
| The most important procedure in preventing the spread of infection is _______________ | Handwashing |
| A nonliving vector is also called a ______________ | Fomite |
| An infection that occurs and follows another infection is called a/an ______________ | Superinfection |
| An animal disease that is transmissible to humans | Zoonosis |
| Someone who has an infection and can spread it but also no longer has symptoms of the disease | Carrier |
| MRSA stands for _________ | Methicillin–resistant staph aureus |
