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
