20. A mother of 4-year-old child complains that the child developed elevated body temperature, tenesmus, diarrhea, and abdominal pain attacks. The child attends a preschool facility. Laboratory analysis detected mucus and blood admixtures in the child’s feces. Name the changes that occur in the gastrointestinal tract during dysentery:
A. Enterocolitis B. Enteritis
C. Gastroenteritis D. Gastritis E. Colitis
21. A 23-year-old woman presents to the emergency department complaining of bloody diarrhea, fatigue and confusion. A few days earlier, she went to a fast food restaurant for a birthday party.

A. Shigella dysenteriae B. Shigella flexneri
C. Shigella sonnei D. Shigella boydii E. Shigella Newcastle


Cholera
1. Microscopy of a smear taken from the film that appeared on the peptone water 6 hours after seeding and culturing of a fecal sample in a thermostat revealed mobile gram-negative bacteria curved in form of a comma that didn’t make spores or capsules. What microorganisms were revealed?
A. Vibrios B. Spirochetes C. Clostridia D. Corynebacteria E. Spirilla
2. Vomiting matters of a patient suspected of having cholera were delivered to the bacteriological laboratory. The material was used for preparing a "hanging drop" specimen. What type of microscopy will be applied for identification of the causative agent by its mobility?
A. Phase-contrast microscopy B. Electron microscopy
C. Immune and electron microscopy
D. Fluorescence microscopy E. Immersion microscopy
3. Bacilli were extracted from investigated sample. The bacilli are curved, extremely mobile, gram-negative, form no spores or capsules, have anaerobic form of respiration. They form transparent smooth colonies in alkaline agar, ferment saccharose and mannose into acid, produce exotoxin, fibrinolysin, collagenase, and hyaluronidase. What agent was extracted?
