A 22 year old woman was admitted to the emergency department at 3:00 a.m. complaining of burning during urination and severe vaginal itching. The physician ordered urinalysis and a vaginal swab for microscopic examination. The technologist observed many motile organisms measuring approximately 12 um in diameter in both the wet mount preparations. The following is what was observed in the wet mount Questions 1) What is the likely genus and species of this organism? 2) Besides size and shape, what is the hallmark diagnostic feature, observable under the microscope? 3) How is this infection acquired? 4) What is the life cycle of this organism? 5) What symptoms are seen in men that are infected with this organism? Does this contribute to the spread of disease? If so, how? 6) What are the S&S of infection in women?

A 22-year-old woman presents at the walk-in health clinic with a slight fever (38.5°C), a complaint of frequent urination, burning on urination, vaginal discharge, and a small lesion on the labia. The woman reported that she was moderately sexually active and had three sexual partners in the past six months. Her last sexual contact was about 7 days earlier. She had developed mild symptoms about 5 days earlier, beginning with a discharge from the vagina. She began having pain on urination about 3 days earlier. Urine analysis revealed a pH of 8.2, some white cells, and a few red blood cells. There was protein in the urine. A smear of the vaginal secretion showed a number of Gram-negative cocci. Questions: 1. What is your diagnosis here? Explain the reasoning behind your choice. 2. What was the most likely organism? 3. Describe the mode of transmission. 4. Describe what clinical features are critical to your diagnosis. 5. What is the recommended treatment? 6. What further actions must be taken?

Clinical History: A 22-year-old woman with fever, pelvic pain, and vaginal discharge for 3 weeks. On physical examination, she has lower abdominal adnexal tenderness and a painful, swollen left knee. Laboratory studies show a WBC count of 11,875/mm3 with 68% segmented neutrophils, 8% bands, 18% lymphocytes, and 6% monocytes. Vaginal discharge was submitted to the laboratory. What culture media will you use to isolate the bacteria?
