| Humoral Immunity | Stimulation of B cells and antibody production. |
| Illness Stage | Time interval when client is presenting or manifesting specific symptoms of an infectious agent. |
| Incubation Period | Time interval between entry of an infectious agent in the host and the onset of symptoms. |
| Infection | Actual invasion and multiplication of microorganisms in body tissue with cellular injury. |
| Infectious Agent | Microorganism that causes infections. |
| Inflammation | Nonspecific cellular response to tissue injury or infection; involves increased blood flow in the affected area. |

| Medical Asepsis | Practices that reduce the number, growth, and spread of microorganisms. |
| Mode of Transmission | Process that bridges the gap between the portal of exit of the biological agent from the reservoir and the portal of entry of the susceptible “new” host. |
| Nosocomial Infection | _____ acquired in the hospital that was not present or incubating at the time of the client’s admission. |
| Pathogen | Microorganisms that cause disease. |
| Pathogenicity | Ability of a microorganism to cause disease. |
| Physical Agent | Factor in the environment capable of causing disease in a host. |
| Prodromal Stage | Time interval from the onset of nonspecific symptoms until specific symptoms of the infectious agent begin to manifest themselves. |
| Resident Flora | Microorganisms that are always present, usually without altering the client’s health. |
| Sterilization | Total elimination of all microorganisms including spores. |
| Surgical Asepsis | Practices that eliminate all microorganisms from an object or area. |
| Surgical Antisepsis | _____ handwash or _____ hand rub performed preoperatively by surgical personnel to eliminate transient and reduce resident hand flora. Antiseptic detergent preparations often have persistent antimicrobial activity |
