BMT Emerging Disease Vocab Review

Organism that can grow in the presence of atmospheric oxygen

Living organism that transfers an infective agent from one host to another

Resistance of a population to the spread of an infectious organism due to the immunity of a high proportion of the population

Infection produced by a pathogenic agent that a patient acquires during hospitalization or treatment inside another healthcare facility

Localized protective response to tissue injury or destruction. In acute form, it is characterized by pain, heat, redness, and swelling in the injured area

Disease producing agent

Rod-shaped bacterium

Transmission of an infectious organism in which the organism is truly suspended in the air or travels a meter or more from the source to the host. Chicken pox, flu, measles, and polio are examples of diseases caused by airborne agents

Body of an organism that harbors another organism. This provides a microenvironment that supports the growth and reproduction of the parasitic organism

First disease case in an epidemic within a population

Infectious particle that is responsible for certain slow-acting diseases such as scrapie in sheep and goats, and Creutzfelt-Jakob disease in humans. These particles have a protein component, but scientists have not yet detected a nucleic acid component

Transmission of an infectious pathogen between hosts by way of a vector

Rigid, spiral-shaped bacteria

Microorganisms that are normally associated with a particular tissue or organ

Sudden increase in occurrence of a disease above the normal level in a particular population
