Causative agents of Campylobacteriosis and Helicobacteriosis
155. Apatient C., 28 years old, was taken to hospital with acute colitis with signs of moderate intoxication, diarrhoea. Feces were with blood contaminant. Catalase positive and gram-negative bacteria-microaerophilic were isolated during feces bacteriological investigation. They don’t grow at 25°C, urease-negative, when two cells are taken together they look like ”sea-gull wing”, don’t produce spores and capsules, mobile. What bacteria are such features characteristic for?
– Escherichia coli.
– Haemophilus influenzae.
– Proteus vulgaris.
+ Campylobacter jejuni.
– Salmonella typhi.
156. After investigation of the material taken from a patient, the diagnosis Campylobacteriosis was made bacteriologically. What peculiarity of bacteria eliminated from the patient was taken into consideration during cultivation?
– The presence of the enzyme urease.
+ Microaerophilic.
– Cells of gastric type colonization.
– Spores and capsules absence.
– Six polar flagella presence.
157. Inkindergarten an outbreak of gastroenteritis, similar to campylobacteriosis was registered. What serological reaction can be used to prove the diagnosis?
– Haemagglutination inhibition test.
+ Passive haemagglutination test.
– Neutralisation test.
– Precipitation test.
– Haemagglutination test.
158. During microbiological investigation of feces of a patient. “Campylobacteriosis“ diagnosis was made. What basic method of diagnostics was used?
– Microscopic.
– Biological test.
+ Bacteriological.
– Serological (CFT).
– Immunoblotting.
159. Inthe study of biopsy samples from a patient with easophagogastroduodenoscopy, the patient was bacteriologically diagnosed with helicobacteriosis. Which feature of the bacteria was recorded by bacteriologist, within the culture?
+ Microaerophilic.
– The presence of the enzyme urease.
– Colonization gastric cell type.
– The absence of spores and capsules.
– The presence of six polar flagella.
160. Ina patient with gastric ulcer disease, after fibrogastroscopy had a biopsy of mucosa in ulcers. From the biopsy it was prepared smear-imprint, it was painted by Gram’s method. Balance biopsy used for the production of samples for urease activity. During the observation on the microscopy of the smear-print, bacteriologist identified gram-negative spiral microorganisms; test positive urease activity. What bacterium was detected?
+ Helicobacter pylori.
– Shigella flexneri.
– Spirilla minor.
– Campylobacter jejuni.
– Treponema pallidum.
161. Patient assigned to determine the bacteriological examination aetiology of gastric ulcer. Which pathogen do you suggest will be identified?
+ Helicobacteria.
– Shigella.
– Leptospira.
– Salmonella.
– Listeria.
162. A45-year-old man was diagnosed with gastric ulcer by X-ray. Which medium will you use for culturation of the biopsy material from the site of ulcers for the bacteriological confirmation of diagnosis?
+ At the medium for the identification of the enzyme urease.
– On blood agar.
– On Endo agar.
– On Ploskirev’s medium.
– On meat-peptone agar.
163. A28-year-old patient was hospitalized with signs of moderate intoxication and diarrhoea. Patient feces contain an admixture of blood. During the bacteriological study of feces, bacteriologist identified spiral catalase-positive gram-negative bacteria-microaerophilic. Pathogen has urease activity, spores and capsule does not form, mobile. Which bacterium is characterized by such features?
– Escherichia coli.
– Haemophilus influenzae.
– Proteus mirabilis.
+ Helicobacter pylori.
– Salmonella typhi.
164. Apatient has frequent relapses of ulcer disease, the doctor appointed analysis of Helicobacteriosis. the most reliable results of the study will be obtained. With the help of which microbiological method?
+ Bacteriological.
– Microscopic.
– Immunoblotting.
– Respiratory test.
– Serological (ELISA).
165. Microflora of stomach, which is related to the acidity of gastric juice. Helicobacter pylori survives in gastric juice and is one of the causes of peptic ulcer disease. Which enzyme provides survival of Helicobacter pylori in gastric juice?
+ Urease.
– Protease.
– Adenylcyclase.
– Lipase.
– Hyaluronidase.
166. Patient revealed gastric ulcer. When bacteriological study of biopsy taken from the damaged section of stomach, on the 5th day on chocolate agar, grew small colonies of gram-negative oxidase-positive spiral bacteria. Which microorganism is most likely to cause stomach ulcers?
