Latency is a key adaptation in some animal viruses and likely evolved to prolong the infection by avoiding a strong and effective immune response. Which of the following types of viruses would you expect to require periods of latency? a. viruses that have large genomes and require a long time for replication b. viruses that require a long time for transmission to new host organisms c. viruses that require a long time for assembling into complex structures d. viruses that infect cells of the immune system
Which of these viruses is spread through mouse urine or feces? a. Epstein-Barr b. hantavirus c. human immunodeficiency virus d. cytomegalovirus
11. A 21-year old woman at 16 weeks' gestation presents with several vesicular lesions on her labia majora (outer vaginal folds). When asked if the lesions have appeared previously, she mentions she has had them at other times. Results of a Tzanck test revealed multinucleated giant cells. Which of the following organisms is the most common cause of this patient's infection? A. Herpes simplex 1 B. Herpes simplex 2 C. Cytomegalovirus D. Treponema pallidum E. Microsporum gimmesum 12. Knowing that the patient is pregnant (from question 11) and has a recurring infection and to prevent infection of her child, the physician should advise the patient about which of the following? A. Deliver the infant vaginally even if the lesions are present during labor and delivery. B. Deliver the infant by caesarian section if the lesions are present during labor and delivery. C. Deliver the infant vaginally while treating the mother with acyclovir. D. Avoid sexual contact with partners who have lesions similar to these. E. The lesions are a sign that the fetus has been infected in utero and it is highly likely to be adversely affected or that it will die.
