| Antibiotic Sensitivity Testing |
|
Definition
| The identification of the concentration of various antibiotics to which a particular microorganism is sensitive. |
|
|
Term
|
Definition
| A globulin, found in tissue fluids and blood serum, produced in response to the stimulus of a specific antigen, and capable of combining with that antigen to neutralize or destroy it. Globulins are often referred to as "immune substances". |
|
|
Term
|
Definition
| That portion or product of a biologic agent capable of stimulating the formation of specific antibodies. |
|
|
Term
|
Definition
| The chemical arrangement of the Antigenic components of an agent, which arrangement and components are unique to each species or strain of agents, and which are responsible for the specificity of immunity resulting from infection with that agent. |

|
Term
|
Definition
| Ability of an agent or its products to stimulate the formation of antibodies. |
|
|
Term
|
Definition
| The prevention of sepsis by inhibition or destruction of the causative organism. |
|
|
Term
|
Definition
| Antibody to the toxin of a microorganism, usually a bacteria exotoxin. Antitoxin combines with specific toxin, in vivo and in vitro, with the consequent neutralization of toxicity. |

|
|
Term
|
Definition
A person or animal that harbors a specific infectious agent (but manifests no discernible clinical disease) and is a potential source of infection for man or animals.
The carrier state can occur in an indiviudal with an infection innaparent throughout its course or, if the infection leads to disease, the carrier state may only occur during the incubation, convalescent, and post-convalescent periods.
While in these states, a person or animal is commonly referred to as incubatroy carrier or convalescent carrier.
The carrier state can be of short or long duration (temporary carrier or chronic carrier). |

Term
|
Definition
An infected or diseased person or animal having specific clinical, laboratory and epidemiologic characteristics.
Confimed Case: A person from whom a disease-producing agent has been isolated and identified or from whom has been obtained other laboratory evidence of the presence of an etiologic agent, i.e., a four-fold or greater rise in antibody titers between acute and convalescent serum specimens, whether or not that person has a clinical syndrome indicative of the disease caused by the agent.
Presumptive Case: A person with a clinical syndrome compatible with a disease but without laboratory confirmation of the etiologic agent. |
