| Steam and pressure | Two methods that are effectively combine when using an autoclave |
| Health care associated infections | infections patients get while receiving medical treatment |
| the second event in the chain of infection | source of reservoir |
| causes cell membrane loss of semipermeability leading to lysis and denaturing of the cell's protein | quaternary ammonium compounds |
| acetic acid | also known as vinegar. Used as a food preservative. |
| causes cell leakage and inactivates enzymes in the cell membrane | phenols |
| the fifth event in the chain of infection | portal of entry |
| widely used in cleaning surgical instruments | glutaraldehydes |
| sanitizer | reduces the microorganisms to safe levels on inanimated objects |
| the thrid event in the chain of infection | portal of exit |
| their are two concentrations in this cleaning solution 90% and 70% | alchohol |
| preventing infection by inhibiting the growth or action of microorganisms | germicidal |
| the first event in the chain of infection | causative agent |
| The process of making a person, object, or environment free of microorganisms | decontaminant |
| will kill most bacteria and inactivate most virus if immersion is at least 15 minutes. | boiling water |
| destroys harmful orgaisms without major changes in the chemistry of the food | pasteurization |
| the highter the temperature used, the less is needed to disinfect or sterilize. A 10 degree F increase can double the killing rate. | heat |
| Center of disease and prevention | serves to protect public health through the control and prevention of disease |
| the forth event in the chain of infection cycle | mode of transmmission |
| the fifth event in the chain of infection | portal of entry |
| chloride | 1:50 diluted solution is used to kill gram(-) bacteria. 1:10 diluted solution is used to clean up blood spills. |
| Hydrogen peroxide | A 3% solution is used as a mild antiseptic to clean skin around wounds |
| The sixth event in the chain of infection | susceptible host |
| disinfectant | cleaning technique that destroy or prevent and prevent growth of organisms capable of infection |
