*Phase-contrast

Electron microscopy

Immune electron

Luminescent

Immerse type

*A vomiting mass of patient with suspected cholera was sent to the bacteriological laboratory. A smear “hanging drop” was prepared from the sample to microscopy it with dark field technique and indicate motility of causative agent that is established as important diagnostic criterion. Which reagent should the smear be treated before microscopy with?

Luminescent serum

desinfection solution

Methylene blue solution

Alkaline peptone water

* A pure culture of vibrio was isolated from feces of patient with enteric infection. Which morphological group do these microorganisms belong to?

Cocci

Clostridia

*Spiral

Bacteria

Bacilli

b-12 Patient with diarrhoea was admitted to the infection unit. Gram-negative curved rod-like bacteria

were founded on bacterioscopic examination of faecal masses. What is the most likely disease

in this patient?

A Cholera

B Typhoid fever

C Salmonellosis gastroenteritis

D Diphtheria

E Intestinal form of plague

83. In the feces of a patient with acute gastroenteritis there were revealed motile, slightly curved Gram-negative rods, which grow onto alkaline 1% peptone water in the form of tender bluish pellicle. What microorganisms have such properties?

A. Spirilla.

B.Spirochetes.

C.Clostridia.

D.Bacilli.

E.*Vibrios.

95. As a result of feces inoculation onto 1% alkaline peptone water after 8 hours' incubation with 37° C temperature a growth in the form of tender bluish pellicle was revealed. Microscopy revealed Gram-negative curved rods. What disease could these microorganisms cause?

A. Shigellosis.

B. Plague.

C. Typhoid fever.

D. Paratyphoid fever.

E. *Cholera.

100. A patient is hospitalized to an infectious department with cholera suspected. What basic method of research is necessary to use for the confirmation of the diagnosis?

A. Immunological.

B. *Bacteriological.

C. Biological.

D. Serologic.

E. Allergic.

118. Feces of a patient with cholera were delivered to a laboratory of extremely dangerous infections. What method of microbiological diagnostics is to be used to confirm or deny the diagnosis?

A. Virological.

B. Allergic.

C. Bacterioscopic.

D. Biological.

E. *Bacteriological.

127. From the vomit mass of a patient there were isolated very motile, slightly curved, Gram-negative rods which react positively with Inaba's diagnostic serum. What symptoms, most probably, will appear with the treatment absent?

A. Endotoxic shock.

B. Bacteremia.

C. *Fluid loss. (Dehydration)

D.Skin rash.

E. Ulcerous damages of intestine.

* A girl, 18 years old, from rural area of India has profuse diarrhea with fluid loss up to 8 liters a day. Which from given later microorganism may be reason of this infection?

*Vibrio cholera

Campylobacter jejuni

Enteropathogenic E.coli

Salmonella typhi

Shigella dysentheriae

“01”138. A patient with complaints of repeated diarrhea and vomiting, pain in muscles of legs, general weakness, and vertigo is hospitalized to an infectious department. After examination a doctor has previously diagnosed cholera. Which method of investigation of the specimen from the patient should be used for express-diagnostics ?

A. *Immunofluorescence test.

B. Agglutination test

C. Bacteriological.

D. Allergic.

E. Biological.

*03* A patient with diarrhea was hospitalized into infectious disease department. Microscopy of feces revealed Gram-negative curved rods. Which disease may be suspected?

*Cholera

Salmonella gastroenteritis

Diphtheria

Enteric type of plague

Enteric fever

* A detection of serological variant of V.cholera allows to identify isolated strain and make a control of epidemic situation. Which way is it made by?

*Agglutination test with O-specific and type-specific sera

By Mukerje’s

By Heiberg’s

With detection of polymixin sensitivity

With agglutination of fowl erythrocytes

* Motile, slightly curved Gram-negative rods were isolated from patient’s vomiting mass and they were identified as cholera vibrio. Which test helps to differentiate classical variant of V.cholera from El-Tor biovar?
