Abscess - Answer-A localized area of pus in the body.
Aerobes - Answer-Organisms that require oxygen.
Anaerobes - Answer-Organisms that live in the absence of oxygen.
Antibiotics - Answer-Substances that inhibit growth or destroy microbes.
Antibody - Answer-A protein substance that destroys specific materials in
the body, including pathogenic microorganisms.
Antigen - Answer-A foreign substance in the body which encourages
specific immunity to a disease by stimulating the production of antibodies.
Asepsis - Answer-The absence of microbial contamination that can cause
disease.
Bacteremia - Answer-A single or intermittent spread of microbes from a
primary site or infection into the bloodstream.

the absence of discernible clinical disease and can transmit that pathogenic
microbe to others.
Culture - Answer-A growth of microbes or other living cells; used primarily
to identify the microbe.
Droplet - Answer-Minute particles of moisture expelled from the respiratory
tract by talking, sneezing, or coughing; can contain microbes and serve as
a route for microbe transfer.

Gram Staining - Answer -A method used to distinguish and classify bacteria. Host - Answer -An animal or plant housing a parasite. Infection - Answer -The process by which living pathogenic microorganisms enter the body of the host under conditions favorable for their growth and, by the production of toxins, may require the tissues of the host. Normal Flora - Answer -Bacteria and fungi normally inhabiting the body. Mitosis - Answer -Division of a single cell into 2 identical cells. Meiosis - Answer -Cell division involving sexually reproducing organisms. Nosocomial Infection - Answer -An infection acquired while in a health care facility; more commonly referred to as a healthcare associated infection (HAI). Parasites - Answer -Microorganisms that reside on or within living organisms. Pathogens - Answer -Microbes capable of producing disease. Pus - Answer -The accumulation of decaying cells (WBCs and microbes) and serum; the act of forming pus is called suppuration. Reservoir - Answer -A place where microbes reside and from which they can be transported to the host. Resident Microbe - Answer -A microbe that habitually lives in the epidermis, crevices, and skin folds of the body. Sepsis - Answer -A severe, toxic, febrile state resulting from infection with pyrogenic microbes.

Acquired Immunodeficiency Syndrome (AIDS) - Answer -Condition caused by HIV infection that leads to a severely weakened immune system. Herpes simplex virus - Answer -Causes cold sores on the lips or mouth and genital herpes in the perianal region. Herpes zoster virus - Answer -Causes shingles. Human Papilloma Virus (HPV) - Answer -Causes venereal warts (condylomas). Cytomegalovirus infection - Answer -Causes enlargement of affected organs and can be spread by direct contact with body fluids. Prion diseases - Answer -Small bits of protein that act like a virus; contain no detectable DNA or RNA. Bacteria - Answer -Distributed throughout nature; reproduce asexually by binary fission. Cocci - Answer -Round (spherical) nonmotile microbes. Streptococci - Answer -Appear in chains; can cause diseases such as scarlet fever and pneumonia. Staphylococci - Answer -Appear in clusters; can be saprophytic or parasitic. Diplococci - Answer -Appear in pairs; can cause pneumococcal infections.

Cell wall - Answer -Confines and protects the bacterial cell.

Cytoplasmic membrane - Answer -Serves as a doorway to the cell and a site for enzyme production. Cytoplasm - Answer -Jellylike substance inside the cell where proteins are made. Nuclear material - Answer -Responsible for cell division and hereditary characteristics. Flagella - Answer -Projecting strands of protein that enhance motility. Capsule - Answer -Thick layer around the cell that acts as a defense mechanism against WBCs. Endospore - Answer -Tough resistant shell that is extremely resistant to destruction. Endotoxins - Answer -Poisons contained within the bacterial cell wall that can produce septicemia. Exotoxins - Answer -Poisons produced by bacteria that can cause diseases such as diphtheria. Drug-resistant organisms - Answer -Bacteria that are resistant to multiple drugs, posing a significant threat in healthcare. Methicillin-resistant Staphylococcus aureus (MRSA) - Answer -Transmitted by contact; requires strict perioperative protocols. Vancomycin-resistant enterococci (VRE) - Answer -Transmitted by contact; requires strict contact precautions.
