Chapter 5 - Infectious Disease Process

Mosquito

Which of the following is an arthropod vector?
a. pig
b.dog
c.human
d.mosquito

arthropod vector

Ticks, mites, fleas, lice, true flies & mosquitoes

Adhesins

What do pathogens use to attach to the host tissues after they have entered the body?
a. enzymes
b. fimbriae
c. glycocalyx
d. adhesins

Erythrocytes

Kinases Lyse?
a. fibrinogen
b. hyaluronic acid
c. erythrocytes
d. fibrin

Gastrointestinal tract

Enterotoxins affect:
a. nerve impulse transmission
b. gastrointestinal tract
c. urinary tract
d. host cells

Leukocytes

Phagocytes are:
a. leukocytes
b.erythrocytes
c.platelets
d. plasma

Leukocytes

White blood cells

True

Interferon inhibits the synthesis of proteins that are needed by viruses for multiplication: T or F

True

Pathogens that are responsible for the formation of an abscess are called pyogenic bacteria: T or F

False

Eosinophils are classified as an agranulocyte: T or F

Eosinophils

white blood cell that are responsible for combating infection by parasites

agranulocyte

Nongranular leukocyte. This is one of the two types of leukocytes found in plasma that are classified as either monocytes or lymphocytes.

True

The primary function of the reticuloendothelial system is the removal of debris, dead leukocytes and erytthrocytes, and cellular secretions: T or F

False

Complement is a protein that resides in the liver: T or F

Eosinophils produce toxic proteins to fight parasites

What is the primary role of eosinophils?

Transforming viruses cause host cells to be abnormally shaped and their growth is unregulated since they do not recognize contact inhibition

What is the reason for the abnormal, uninhibited growth of cancerous cells?

Helicobacter pylori

What organism survives the harsh acidic environment of the stomach and is a contributor to stomach and duodenal ulcers forming

Convalescent carrier

What carrier carries a pathogen and can transmit the disease while recovering from the disease?

Hyaluronidase

What enzyme secreted by some bacteria is responsible for breaking down connective tissue, but has therapeutic uses?

(D) - Leukocidin - Lyse macrophages
(E) - Coagulases - coagulate fibrinogen
(A) - Kinases - dissolve clots
(C) - Collagenase - Lyses collagen
(B) Hemolysin - lysis erythrocytes

Match Column A with Column B
____Leukocidin
____Coagulases
____Kinases
____Collagenase
____Hemolysin

a. dissolve clots
b. lysis erythrocytes
c. lyses collagen
d. lyse macrophages
e. coagulate fibrinogen
