Appendix A
Glossary and Acronyms

GLOSSARY

This glossary is intended to define terms commonly encountered throughout this report as well as some terms that are commonly used in the public health arena. This glossary is not all inclusive. New terms and new usages of existing terms will emerge with time and with advances in technology. The definitions for the terms presented here were compiled from a multitude of sources.


Anthropogenic:

Of, relating to, or resulting from the influence of human beings on nature.

Antibiotic:

Class of substances or chemicals that can kill or inhibit the growth of bacteria. Originally antibiotics were derived from natural sources (e.g., penicillin was derived from molds), but many currently used antibiotics are semisynthetic and are modified by the addition of artificial chemical components.

Antibiotic resistance:

Property of bacteria that confers the capacity to inactivate or exclude antibiotics or a mechanism that blocks the inhibitory or killing effects of antibiotics.

Antimicrobial agents:

Class of substances that can destroy or inhibit the growth of pathogenic groups of microorganisms, including bacteria, viruses, parasites, and fungi.

Attenuate:

To reduce the severity of (a disease) or virulence or vitality of (a pathogenic agent).

Bacteremia:

The presence of bacteria in the bloodstream.

Bacteria:

Microscopic, single-celled organisms that have some biochemical and structural features different from those of animal and plant cells.

Bacteriophage:

A virus that infects bacteria—also called phage.

Basic research:

Fundamental, theoretical, or experimental investigation to advance scientific knowledge, with immediate practical application not being a direct objective.

Benchmark:

For a particular indicator or performance goal, the industry measure of best performance. The benchmarking process identifies the best performance in the industry (health care or nonhealth care) for a particular process or outcome, determines how that performance is achieved, and applies the lessons learned to improve performance.

Broad-spectrum antibiotic:

An antibiotic effective against a large number of bacterial species. It generally describes antibiotics effective against both gram-positive and gram-negative classes of bacteria.

BSL (Biosafety Level):

Specific combinations of work practices, safety equipment, and facilities, designed to minimize the exposure of workers and the environment to infectious agents. Biosafety Level 1 applies to agents that do not ordinarily cause human disease. Biosafety Level 2 is appropriate for agents that can cause human disease but whose potential for transmission is limited. Biosafety Level 3 applies to agents that may be transmitted by the respiratory route, which can cause serious infection. Biosafety Level 4 is used for the diagnosis of exotic agents that pose a high risk of life-threatening disease, which may be transmitted by the aerosol route and for which there is no vaccine or therapy.


Campylobacter:

The leading cause of bacterial food poisoning, caused by a Campylobacter jejuni, most often spread by contact with raw or undercooked poultry. A single drop of juice from a contaminated chicken is enough to make someone sick with campylobacteriosis (disease due to Campylobacter bacteria).

CDC (Centers for Disease Control and Prevention):

A public health agency of the U.S. Department of Health and Human Services whose mission is to promote health and quality of life by preventing and controlling disease, injury, and disability.

Clinical practice guidelines:

Systematically developed statements that assist practitioners and patients with decision making about appropriate health care for specific clinical circumstances.

Clinical research:

Investigations aimed at translating basic, fundamental science into medical practice.

Clinical trials:

As used in this report, research with human volunteers

Emerging infections:

Any infectious disease that has come to medical attention within the last two decades or for which there is a threat that its prevalence will increase in the near future. Many times, such diseases exist in nature as zoonoses and emerge as human pathogens only when humans come into contact with a formerly isolated animal population, such as monkeys in a rain forest that are no longer isolated because of deforestation. Drug-resistant organisms could also be included as the cause of emerging infections since they exist because of human influence. Some recent examples of agents responsible for emerging infections include human immunodeficiency virus, Ebola virus, and multidrug-resistant Mycobacterium tuberculosis.

Encephalitis:

An acute inflammatory disease of the brain due to direct viral invasion or to hypersensitivity initiated by a virus or other foreign protein.

Endemic:

Zoonotic diseases represent one of the leading causes of illness and death from infectious disease. Defined by the World Health Organization, zoonoses are “those diseases and infections that are naturally transmitted between vertebrate animals and man with or without an arthropod intermediate.” Worldwide, zoonotic diseases have a negative impact on commerce, travel, and economies. In most developing countries, zoonotic diseases are among those diseases that contribute significantly to an already overly burdened public health system. In industrialized nations, zoonotic diseases are of particular concern for at-risk groups such as the elderly, children, childbearing women, and immunocompromised individuals.

The Emergence of Zoonotic Diseases: Understanding the Impact on Animal and Human Health, covers a range of topics, which include: an evaluation of the relative importance of zoonotic diseases against the overall backdrop of emerging infections; research findings related to the current state of our understanding of zoonotic diseases; surveillance and response strategies to detect, prevent, and mitigate the impact of zoonotic diseases on human health; and information about ongoing programs and actions being taken to identify the most important needs in this vital area.
