45 The etiologic agent of this painless ulcer is seen on Dark Field microscopy as a ______________________________________.

46 *__true or false___ Tertiary syphilis is characterized by diffuse, granulomatous, necrotizing masses and is not easily transmitted to other people.

47 _____ Lesions of secondary syphilis

1. Are only in the oral cavity.
2. Are oral and cutaneous.
3. Are not infectious.
4. Are present for 6 to 10 weeks duration.
5. Imply that the patient is self-cured without antimicrobial therapy.

51 *_true or false_____ Human papillomavirus (HPV) is the causative agent for external and internal genital warts and can be a major factor in the development of cervical cancer.

55 _____ Once the initial viremia of HIV occurs,

1. HIV totally disappears from the human body.
2. those infected immediately begin to have immunocompromised.
3. the number of HIV viral particles in the bloodstream decrease as HIV continues to multiply and damage CD4 lymphocytes.
4. HIV is 100% undetectable within the body cell tissue.
5. patients exhibit signs that can easily be diagnosed as AIDS.

56 *__true or false___ A dual or co-infection with HIV and Epstein-Barr virus (EBV) can result in the condition called Oral Hairy Leukoplakia, thickened tongue epithelium which inhibits dietary intake.

Ans .(51) True

Ans .(55) option (c) the number of HIV viral particles in the bloodstream decreases as the HIV continues to multiply and damage CD4 lymphocytes.
