WGU D311 UAM1 EXAMINATION TEST
ACCURATE QUESTIONS AND ANSWERS
◉ Vibrio cholerae
Answer: cholera- N methylphenidate- intestinal epithelial cells
◉ antigenic variation
Answer: Alter surface proteins so the pathogen is not recognized
by the host immune system
◉ How can microorganisms evade the immune system ?
Answer: Antigenic variation, bacteria produce capsules, acid fast
bacterium produce waxy substances/ mycolic acid
◉ Influenza virus
Answer: Dz: influenza
attach: Hemagglutinin/ sialic acid of resp intestinal cells
◉ Herpes simplex virsus
Answer: Dz: oral/genital herpes
attach: Glycoproteins gab, gC, gD. Heparin sulfate on mucosal
surfaces of mouth and genitals
, ◉ human immunodeficiency virus
Answer: Dz: HIV
attach: Glycoprotein gp 120- CD4 and CCR5 or CXCR4 of immune
system cells
◉ antigentic shift
Answer: A MAJOR change in the antigentic structure of the causal
agent due to the recombination of the genetic material from two
different strains of the causal agent. More dangerous
◉ Antigenic drift
Answer: Minor change in influenza virus antigens due to gene
mutation
◉ Virulence factors for Candida albicans (fungus)
Answer: Surface glycoprotein.
invades proteases, keratinase, and phospholipase
cause oral thrush and vaginal yeast infection
◉ Virulence factor for cryptococcus (fungus)
Answer: Capsule made of glucuronoxylomannan
cause pneumonia and meningitis
◉ Virulence factors for claviceps (fungus)
