A+ GRADED, GUARANTEED SUCCESS!
What is the main focus of the notes regarding double-stranded DNA viruses? Answer:
The main focus is on the family of viruses, particularly human papillomavirus (HPV).
How many different serotypes of HPV are there, and how many are considered sexually
transmitted? Answer: There are more than 100 different serotypes of HPV, with 40
considered sexually transmitted.
Which HPV serotypes are associated with a high risk of developing cervical cancer?
Answer: Certain high-risk serotypes are covered by the HPV vaccine, including those
that are nine-valent or ten-valent.
What types of warts can HPV cause? Answer: HPV can cause plantar, genital, or flat
warts.
What is the most common cause of cervical cancer? Answer: HPV is the most common
cause of cervical cancer.
How are HPV infections typically tested? Answer: HPV infections are tested using
tissue culture or molecular techniques.
Who can receive the HPV vaccine? Answer: The HPV vaccine is approved for both
males and females.
What are coilocytes, and why are they significant in HPV testing? Answer: Coilocytes
are abnormal cells with larger nuclei and irregular membranes, indicating potential
precancerous changes, and are looked for during Pap smears.
What happens if a Pap smear result is abnormal? Answer: If a Pap smear result is
abnormal, further DNA testing for HPV may be performed.
What is the historical significance of the smallpox vaccine? Answer: Smallpox was the
first disease to have a vaccine, which led to its eradication.

, How is smallpox transmitted? Answer: Smallpox is transmitted through respiratory
droplets or fomites.
What is the fatality rate of smallpox in unvaccinated individuals? Answer: The fatality
rate of smallpox in unvaccinated individuals is approximately 30%.
What distinguishes smallpox lesions from chickenpox lesions? Answer: Smallpox
lesions are more deeply embedded and concentrated on the head and limbs, while
chickenpox lesions are more widespread across the trunk.
What family of viruses does Parvovirus B19 belong to? Answer: Parvovirus B19
belongs to the family of Parvoviridae, which are the smallest DNA viruses.
What is a fomite? Answer: A fomite is an inanimate object or surface that can carry
infectious agents.
What is the cytopathic effect associated with HPV? Answer: The cytopathic effect
associated with HPV is the presence of coilocytes.
What is the role of pathologists in HPV testing? Answer: Pathologists analyze test
results from Pap smears and may recommend further testing or treatments.
What are the characteristics of normal epithelial cells compared to coilocytes? Answer:
Normal epithelial cells have smaller nuclei and regular shapes, while coilocytes have
larger nuclei and irregular membranes.
When was the smallpox vaccine halted in the U.S.? Answer: The smallpox vaccine was
halted in the U.S. in 1972.
What is the bioterrorism threat associated with smallpox? Answer: Smallpox is
considered a bioterrorism threat due to the potential for outbreaks in unvaccinated
populations.
What is the significance of the HPV vaccine for males? Answer: Males can be silent
carriers of HPV and may transmit the virus without exhibiting symptoms.
What is the primary method for identifying HPV in laboratory settings? Answer: HPV is
identified using molecular techniques or tissue culture.
