  1. TEAM CASE STUDY 3. EUKARYOTIC – PROTOZOA. WELCOME.

  2. A 24 year old woman is referred to a health clinic as a result of contact from tracing a case of gonorrhoea. She recently had unprotected sex with her male partner but showed no symptoms. A pelvic examination recovers a greenish discharge containing protozoa with characteristic “jerky” motility. The woman tested negative for gonorrhoea. HISTORY

  3. INFORMATION & QUESTIONS. • Medical history. Is she on any medications? • Is she pregnant? • Does she have any abdominal pain? • Has her partner been examined? Has she had any other STDs before?

  4. MORE QUESTIONS CONT. • What’s her profession? Are there any known allergies in her history? • Has she had any invasive surgeries ( abortion)? • Has she been traveling?

  5. DIFFERENTIAL DIAGNOSIS. • Giardiasis-caused by a diplomonad protozoa of the intestinal tract. • Cryptosporidiosis-caused by a parasite & acquired through contaminated drinking water or food, or exposure to fecal/matter. • Bacterial Vaginosis-decline in lactobacilli. • 1. Gardnerelle Vaginalis • 2. Mycoplasma Hominis.

  6. DIFFERENTIAL D. CONT. • Reaction to disruption of normal microbiota by broad-spectrum antibodies. • Candida Albicans (Yeast) –caused by erythromycin. • Trichomonas Vaginalis-parasite that infects (Trichomonas) the reproductive sysytem. It is a sexualy transmitted diseases called Trichomoniasis.

  7. LIST OF THE MOST PROBABLES. 1.Trichimoniasis- an oval trophozite with 5 flagella. Does not have a cyst. 2.Giardiasis- Has a cyst. Symptoms include abdominal pain, flatus, nausea, vomiting, loss of appetite, ineffective nutrients absorption, low fever, foul smelly stool( rotten eggs) like hydrogen sulfide. 3.Crytosporidiasis- banana shaped – diagnosis is made from the oocysts in the feces.

  8. LIST CONT. 4.Yeast infection- caused by various species of candida. Vaginal discharge is curd like and slight. 5.Allergy- caused by erythromycin which kills the lactobacteria. 6.Bacteria Vaginasis- caused by gram positive bacteria which produces a whitish discharge.

  9. MOST LIKELY ETIOLOGICAL AGENT. • Trichomonas vaginalis.

  10. TESTS. • In men diagnosis is made from urethra specimen. • In women a pelvic exam is performed &vaginal samples collected. Then the parasite is viewed under a microscope (wet mount). • A culture.

  11. TESTS CONT. • Wet mount of the vaginal discharge. • Stain viewed under fluorescent microscope. • Polymerase chain reaction testing (PCR).

  12. A trophozoitevaginalis from culture. Flagella and single nucleus are visible. DIAGRAM 1.

  13. Two trophozoites of Trichomonas Vaginalis. DIAGRAM 2.

  14. Trophozoites in a vaginal smear. ( Papanicolaou stain, oil immersion). DIAGRAM 3.

  15. SCIENTIFIC CLASSIFICATION. • Kingdom-Protista. • Phylum-Metamonada. • Class-Parabasalia. • Order-Trichomonadida. • Genus-Trichomonas. • Species-T. vaginalis.

  16. The patient has an infection called Trichimoniasis vaginalis. One of the most common infections in the United States, especially in HIV patients. WHAT’S WRONG WITH THE PATIENT & HOW COMMON IS THE INFECTION?

  17. POSSIBLE CAUSES. • Contraction through unprotected sex with multiple partners. • Contact with contaminated towels.

  18. MEN Asymptomatic- most of the time. Urethra discharge if present. Burning sensation. WOMEN Vagina discharge-green & smelly. Lower abdominal pain. Genital inflammation, itching/redness. Tissue erosion. Painful intercourse. SYMPTOMS PRODUCED IN MEN AND WOMEN.

  19. MALE May cause urethritis if left untreated. FEMALE May cause cystitis/ urethritis if left untreated. SYMPTOMS CONT.

  20. TREATMENT. • Metronidazole 2 grams. Has a 90% rate since it is given at once. It is also effective in treating male partners. • Tinidazole.

  21. PREVENTION • Abstinence. • Use protection when having intercourse. • Limit sexual partners (recommendation-to one). • Immediate treatment if infected & the partner also.
