means of transmission, portal of entry and susceptible host.
✔✔classification of bacteria - ✔✔Spherical (cocci), rod shaped (bacilli), corkscrew
shaped (spirochetes)
Gram positive or gram negative—based on reaction to Gram stain
Aerobic or anaerobic—based on need for oxygen
✔✔common portals of entry - ✔✔The urinary, respiratory, and gastrointestinal tracts
and the skin
✔✔common portals of exit - ✔✔respiratory, GI, genitourinary tracts, breaks in skin,
blood and tissue
✔✔factors affecting host susceptibility. - ✔✔1) intact skin & mucous membranes
2) normal pH levels
3) body's WBCs
4) Age, sex, race, hereditary factors
5) immunization, natural or acquired
6) fatigue, climate, nutritional & general health status.
, 7) Stress
9) Health status
8) Use of invasive or indwelling medical devices.

response
