In the children's department of the infectious clinic, the boy is diagnosed with "diphtheria."

What drug should be administered to the patient first?

When sowing material from the pharynx from the patient with angina to blood-tellurite agar, colonies with a diameter of 4-5 mm, of gray color, radially striated (in the form of rosettes) grew. Under the microscope, gram-positive rods with club-shaped thickenings at the ends, located in the form of rose-rooted fingers. What are microorganisms?

When the 4-year child was examined for complaints of general weakness, sore throat and difficulty swallowing, the doctor suspected diphtheria and sent the material to the bacteriological laboratory. On which differential diagnostic nutrient medium should they sow the material for the isolation of the causative agent of diphtheria?

The otolaryngologist at the examination of the patient noted flushing, a significant swelling of the tonsils with a gray bloom on them. During microscopy plaque was found, Gram-positive rods are located at an angle to each other. What kind of disease should be suspected?

A patient with suspicion for diphtheria during a bacterioscopic examination of a smear from the pharynx revealed rod-shaped bacteria with the grains of the volute. Which etiotropic drug is the drug of choice in this case?

From the throat of a child with a suspicion for diphtheria was isolated a clear culture of microorganisms and it was studied for its morphological, tinctorial, cultural and biochemical properties, which turned out to be typical for diphtheria pathogens. What research should be done to give an opinion that a pathogenic diphtheria bacillus has been isolated?

To determine the toxigenicity of diphtheria bacillus on a dense nutrient medium, a strip of filter paper impregnated with antitoxic diphtheria serum was placed, and next to it, the studied culture of microbes and a known toxigenic strain were sowed in the form of plaques. If the studied culture of microbes produces exotoxin, then they form:

In the case of bacterioscopic examination of smears from the pharynx stained by Neisser, sticks were found, located at an angle to each other with volutein grains at the ends. What kind of microorganisms can be considered?

Among the children of the school there were cases of angina. When microscopic smears, prepared from a material taken from a tampon with tonsils and stained by Neisser, thin yellow sticks with dark blue grains at the ends were found. The sticks were arranged in the form of a Roman five. What infection can be suspected in this case?

For the causative agent of diphtheria, it is characteristic:

Major factor The pathogenicity of Corynebacterium diphteriae is:

Diphtheria causative agent possesses:

In laboratory diagnosis of diphtheria:

For primary cultivation corynebacterium diphtheria

use:

To identify the causative agent of diphtheria in a smear, you can use coloring:

C.diphtheriae are used to identify signs:

The toxicity of diphtheria is determined using:
