Question 1 continuedGenitourinary tract1a.GonorrheaReservoir-Infected humans serve as reservoirsMode of transmission-occurs via direct mucous membrane-to-mucous membrane contact,usually sexual contact; adult-to-child (may indicate sexual abuse); and mother-to-neonate duringbirth.Diagnostic tests-Gonorrhea in male patients can be diagnosed by the typical appearance ofGram-stained urethral discharge specimens, with numerous white blood cells (WBCs) andnumerous intracellular and extracellular Gram-negative diplococciSpecimens are inoculated tochocolate agar or a modified chocolate agar (such as Thayer-Martin medium, Martin-Lewismedium, or Transgrow).Lactamase testing of isolates is performed, followed by antimicrobial susceptibility testing if theorganism is -lactamase positive. Isolates are usually identified using biochemical tests.Immunodiagnostic procedures are also available2
Question 1 continuedGenitourinary tract1b.SyphilisReservoir- Infected humans serve as reservoirsMode of transmission- occurs via direct contact with lesions, body secretions, mucousmembranes, blood, semen, saliva, and vaginal discharges of infected people, usually duringsexual contact; blood transfusions; or transplacentally from mother to fetus.Diagnostic tests- Primary syphilis can be diagnosed by darkfield microscopy of material scrapedfrom the margin of chancres.Many immunodiagnostic procedures are available, such as the rapid plasma reagin (RPR),Venereal Disease Research Laboratory (VDRL), fluorescent treponemal antibody absorption(FTA-Abs) tests for detecting antibodies in serum or spinal fluid specimens, and fluorescentantibody procedures for detecting antigen in material obtained from lesions or lymph nodes.
