From the feces of a 6-month-old diseased infant, the bacteriologist isolated an Escherichia coli with the O111 antigenic structure. What diagnosis did the doctor make to the sick child?
Collienteritis.
Gastroenteritis.
Cholera disease.
Food Poisoning.
Dysentery disease.
What culture medium will a bacteriologist use for the primary sowing of feces?
Blood agar.
Olkenútsky's culture medium or Russell's culture medium
Hissa culture medium
Ploskirev's culture medium
Sugar broth
In infectious hospital was hospitalized a child with a previous diagnosis of "colienteritis". From the patient's feces, the bacteriologist isolated the Escherichia coli. How did a bacteriologist find out the relevance of E. coli to pathogenic variants?
Microscopy of colored preparations.
By the nature of growth on the environment of Endo.
By bassing.
Based on biochemical properties.
Agglutination reaction with O-sera.
A small number of red colonies grew in bacteriological examination of a four month old baby with symptoms of acute intestinal infection in the environment of Endo. What can be a microorganism?
Staphylococcus.
Salmonella.
Escherichia.
Streptococcus.
Shigela.
A 7-year-old boy has cholera (vomiting, profuse diarrhea). During the study of the feces of the patient on the environment of Endo grew the same colonies of crimson color, with a metallic luster. Which microorganism is the most likely pathogen?
Enterotoxigenic Escherichia coli.
Salmonella enteritis.
Yersinia enterocolitica.
Shigella sonnei.
In a child with acute intestinal infection signs of dehydration quickly developed, blood appeared in the feces. The pediatrician suspected the child had colitis. What method will a bacteriologist use to diagnose enteral escherochiosis?
Bacteriological.
Serological.
Biological.
Skin-allergic test.
Microscopic.
In children of the younger group of the orphanage, the epidemiologist registered an outbreak of intestinal infection with signs of coli-enteritis. What research does a bacteriologist need to use to finally identify a selected pathogen?
To study the antigenic structure of the pathogen.
To determine the sensitivity of the pathogen to antibiotics.
To study the sensitivity of the pathogen to bacteriophages.
To study the biochemical properties of the pathogen.
To study the signs of virulence of the pathogen.
How can one explain the fact that children are not susceptible to dysentery-like Escherichiosis but are infected with serovars of enteropathogenic Escherichia coli?
Presence of IgG.
The presence of IgM.
The presence of serum IgA.
The presence of IgE.
Immunological tolerance.
In an infectious hospital hospitalized 6-month-old baby with signs of acute intestinal infection. For the bacteriological diagnosis of the disease, the bacteriologist sowed feces on the environment of Endo. By the nature of the growth of the pathogen in the nutrient medium, the bacteriologist registered the result - the causative agent of the disease is Escherichia coli. Describe the cultural properties of the pathogen on the Endo medium.
Red colonies with a metallic luster.
Large mucous colonies.
Small colorless colonies.
Pale pink colonies with a white border.
Creeping growth.
The hospital was hospitalized with complaints of general weakness, diarrhea with blood admixtures, and pain in the kidney area. Body temperature is within normal limits. No leukocytes were found during colposcopy. Please indicate which microorganism can cause these symptoms of the disease?
Enterohemorrhagic Escherichia coli.
Enteropathogenic E. coli.
Enterotoxigenic E. coli.
Enteroinvasive E. coli.
Enteroadhesive E. coli.
