The 29-year-old the patient was hospitalized at an infectious hospital with vomiting, severe diarrhea, tenesmus. The feces are discolored, with mucus lumps and impurities of blood. During a bacteriological study of a micro preparation made from a colony material grown on Ploskirev's medium, a bacteriologist found motionless gram-negative rods. The pathogen was partially fermented with lactose for 48 hours. Name the infectious agent.

During a routine examination of customs officers to identify persons with a subclinical form of shigellosis, the bacteriologist received a co-culture that had the following characteristics: 1. Gram-negative rod. 2. On the environment, Endo formed colorless colonies. 3. Peritrich. 4. Carbohydrates ferment to acid and gas. On what grounds did the bacteriologist did not confirm the presence of the shigellosis pathogen?

The patient was hospitalized in the hospital with a preliminary diagnosis of shigellosis. To confirm the diagnosis, the doctor sent the patient's feces to a bacteriological examination. What is the optimal diagnostic environment for a laboratory assistant to differentiate shigellosis pathogens from atypical shigella?

Among the group of tourists (27 people) who used to drink water from the lake, diarrhea occurred in 7 people in two days. What material should be sent to a bacteriology laboratory to determine the etiology of the disease?

In material from a patient diagnosed with shigellosis, the bacteriologist identified shigella that produced exotoxin. What type of shigella is this characteristic?

In a 4-year-old child, after drunk of raw milk, there were signs of impaired gastrointestinal function, namely: abdominal pain, frequent bowel movements, accompanied by spasmodic bowel pain. The feces had a mucous-blood texture. What type of agent is the pathogen that caused this infection?

In a patient who became ill 3 days ago and complained of fever (38 ° C), abdominal pain, frequent rare feces, blood in feces, the doctor clinically diagnosed shigellosis. What method of microbiological diagnosis of bacteriologist is appropriate to apply in this case? What material from the patient should be examined to confirm the diagnosis?

During the study feces of a patient with a previous diagnosis of shigellosis, Ploskirev's medium grew a large number of colonies with a smooth surface and smooth edges. The isolated culture fermented glucose, mannitol and maltose with the formation of acid, while lactose and sucrose did not ferment. What type of bacteria are these characteristics?

Shigella sonnei.

In a patient with signs of colitis, the bacteriologist isolated a pure bacterial culture, which was attributed to the genus Shigella by morphology, cultural and biochemical properties. Which bacteriologist response is appropriate to use to identify the culture?
