a resistance of the body to infection in which the host produces its own antibodies in response to natural or artificial antigens

those that generally appear suddenly or last a short time

methods used to reduce exposure to infectious agents transmitted by airborne droplet nuclei smaller than 5 microns

infectious agent transmitted by droplets or dust

immunoglobulins, part of the body's plasma proteins, defend primarily against the extracellular phases of bacterial and viral infections

a substance capable of inducing the formation of antibodies

agents that inhibit the growth of some microorganisms

freedom from infection or infectious material

an antigen that originates in a person's own body

bacteria in the blood

the most common infection-causing microorganisms

substances produced by some normal flora (e.g., enterobacteria), that can be lethal to related strains of bacteria

those microorganisms carried in blood and body fluids that are capable of infecting other persons with serious and difficult to treat viral infections, namely hepatitis B virus, hepatitis C virus, and HIV

(BSI) generic infection control precautions for all clients except those with diseases transmitted through the air

a person or animal that harbors a specific infectious agent and serves as a potential source of infection, yet does not manifest any clinical signs of disease

also known as cell-mediated defenses, occur through the T-cell system

scar

free of potentially infectious agents

the presence of organisms in body secretions or excretions in which strains of bacteria become resident flora but do not cause illness

a disease that can spread from one person to another

any person at increased risk for an infection

methods used to reduce exposure to infectious agents easily transmitted by direct client contact or by contact with items in the client's environment

laboratory cultivations of microorganisms in a special growth medium

the movement of blood corpuscles through a blood vessel wall

denotes the likely presence of microorganisms, some of which may be capable of causing infection

agents that destroy pathogens other than spores

residue of evaporated droplets that remains in the air for long periods of time

methods used to reduce exposure to infectious agents transmitted by particle droplets larger than 5 microns

process in which leukocytes move through the blood vessel wall into the affected tissue spaces

developing from within

developing from without

material, such as fluid and cells, that has escaped from blood vessels during the inflammatory process and is deposited in tissue or on tissue surfaces

a plasma protein that is converted to fibrin when it is released into the tissues and, together with thromboplastin and platelets, forms an interlacing network making a barrier to wall off an area

connective tissue repair of wounds with tissue that can proliferate under conditions of ischemia and altered pH

 infection-causing microorganisms that include yeasts and molds

young connective tissue with new capillaries formed in the wound healing process

antibody-mediated defense; resides ultimately in the B lymphocytes and is mediated by the antibodies produced by B cells

increased blood flow to an area

infections that are the direct result of diagnostic or therapeutic procedures

a specific resistance of the body to infection; it may be natural, or resistance developed after exposure to a disease agent

the disease process produced by microorganisms

local and nonspecific defensive tissue response to injury or destruction of cells

practices that prevent the spread of infection and communicable disease

white blood cells

an increase in the number of white blood cells

an infection that is limited to the specific part of the body where the microorganisms remain

large phagocytes

the aggregating or lining up of substances along a surface or edge (eg, the lining up of white blood cells against the wall of a blood vessel during the inflammatory process)

all practices intended to confine a specific microorganism to a specific area, limiting the number, growth, and spread of microorganisms

bodily defenses that protect a person against all microorganisms, regardless of prior exposure

infections associated with the delivery of health care services in a health care facility

skin, eye, mucous membrane, or parenteral contact with blood or other potentially infectious materials that may result from the performance of an employee's duties

a microorganism causing disease only in a susceptible individual

microorganisms that live in or on another from which it obtains nourishment

a resistance of the body to infection in which the host receives natural or artificial antibodies produced by another source

the ability to produce disease; a pathogen is a microorganism that causes disease

cells that ingest microorganisms, other cells, and foreign particles

a source of microorganisms

microorganisms that normally reside on the skin, mucous membranes, and inside the respiratory and gastrointestinal tracts

the presence of pathogenic organisms or their toxins in the blood or body tissues

occurs when bacteremia results in systemic infection

immune functions directed against identifiable bacteria, viruses, fungi, or other infectious agents

a specified area that is considered free from microorganisms

practices that keep an area or object free of all microorganisms;

a process that destroys all microorganisms, including spores and viruses

 when pathogens spread and damage different parts of the body

techniques to be used with all clients to decrease the risk of transmitting unidentified pathogens; currently, Standard Precautions incorporate UP and BSI

a vector is an animal or flying or crawling insect that serves as an intermediate means of transporting the infectious agent

a vehicle is any substance that serves as an intermediate means to transport and introduce an infectious agent into a susceptible host through a suitable portal of entry

ability to produce disease

nucleic acid-based infectious agents
