BIO 345 EXAM 4 QUESTIONS AND ANSWERS
antigenic shift - Answers -This describes large changes in antigens presented to the
immune system for influenza, causing new species tropism of infectiveness.
antigenic drift - Answers -This describes small, gradual changes to antigenic structure
of influenza spikes.
type A - Answers -This is the primary type of influenza infection every year.
replicates within bacteria - Answers -The bacteriophage is a type of virus that:
integration into the genome of the host - Answers -Lysogenic Virus life cycle means:
the lysogenic and lytic replication - Answers -temperate phages cause
retroviruses - Answers -The technical term for RNA viruses which then make DNA is:
enveloped virus - Answers -Pick the description which best characterizes this virus.
false - Answers -A fully-infectious virus, once released from the host cell, is considered
alive.
lysogenic - Answers -What is the name of viral life cycle B, as shown in the following
picture?
cytopathic effects - Answers -The term for viral infections which physically change the
shape or appearance of the cell, such as cell fusion, morphology change, or giant, multi-
nucleated cell development:
capsid - Answers -The protein shell of a virus, protecting and sometimes intimately
wrapping the nucleic acid is called:
bacteriophage - Answers -Choose the option which most closely describes the
organism pictured here:
influenza - Answers -Between November to Mid-March
rhinovirus - Answers -Roughly, May to June, and another peak at Mid-August to
October
adenovirus - Answers -Any time of the year for a respiratory infection possibility
enterovirus - Answers -Primarily during the Summer
, measles - Answers -Airbourne transmission, rash spreading from the hairline, fever,
koplik spots, exceptionally infectious.
mumps - Answers -Swelling of the salivary glands, airbourne and contact transmission,
orchitis and possible sterilization.
rubella virus (German measles) - Answers -Airbourne and placental transmission,
usually mild symptoms except in infants and in utero development.
Influenza virus - Answers -Airbourne transmission, seasonal distribution, fever,
malaise, pneumonia.
variola virus - Answers -Airbourne and contact transmission, centripedial vesicles,
occasional blindness, extreme scarring, high death rate.
adenovirus - Answers -Airbourne transmission, one of the causes of the common cold,
constant and not seasonal:
vaccinia virus - Answers -Vaccine strain for a now extinct infectious organism, unknown
origin.
monkeypox - Answers -Mostly contact transmission, growing mortality, centripedal
vesicles, emerging infectious disease. Currently found in MSM populations.
Parvovirus B19 - Answers -Airborne and fomite transmission, flushed rash on cheeks,
ears, and trunk of children with fever. Adults experience rheumatoid arthritis-like
symptoms. Immunocompromised
Human Papillomavirus (HPV) - Answers -This virus can be transmitted by fomites or
sexually, causing skin growths and some neck and cervix cancer.
Herpes simplex virus type 2 - Answers -This virus can be transmitted to the gestating
baby through the infected mother, causing keratitis and delayed mental development
Hemagglutinin - Answers -The influenza spike that helps the virion attach and
penetrate host cells.
gp120/gp41 complex - Answers -One of the spikes on HIV that helps with virion
attachment and penetration of host cells.
Paramyxoviridae - Answers -The family of viruses which contains Measles, Mumps,
and Respiratory syncytial virus.
Coronaviridae - Answers -Family of viruses that are associated with a viral pneumonia
outbreak in 2003 and pandemic currently
