Question
### Case Study: Vaginitis Diagnosis Upon microscopic evaluation, a sample from a patient with vaginal burning, itching, and discomfort reveals the presence of yeast cells with pseudohyphae. The patient is diagnosed with vaginitis. Which of the following apply: - ○ Infection with *Gardnerella vaginalis* - ● Infection with *Trichomonas vaginalis* - ○ None of the answers apply - ○ Infection with *Neisseria gonorrhoeae* - ○ Infection with *Lactobacillus* species - ○ Infection with *Treponema pallidum* **Explanation:** The presence of yeast cells with pseudohyphae is typically indicative of a yeast infection, such as one caused by *Candida* species. *Trichomonas vaginalis* is a protozoan parasite, not a yeast, and is characterized by different symptoms and microscopic findings. This question tests the understanding of vaginal infections and their specific microbiological characteristics.

**Case Study: Post-Surgical Abdominal Infection** **Scenario:** Four days after a patient undergoes intestinal tract surgery, they develop an abdominal infection caused by a **G-obligate anaerobe**. **Question:** What is the most likely agent of the infection? **Options:** - ○ Clostridium perfringens - ○ Escherichia coli - ● Peptostreptococcus sp. - ○ Klebsiella pneumoniae - ○ Bacteroides fragilis **Explanation:** The correct answer, marked with a filled-in circle, is **Peptostreptococcus sp.** This bacterium is known to be a gram-positive obligate anaerobe, often involved in abdominal infections following surgeries due to its presence in the normal flora of the gastrointestinal tract. Effective diagnosis and treatment require accurate identification of such anaerobic bacteria.
