A bacteriological laboratory received a sample of dried fish from an outbreak of food poisoning. Inoculation of the sample on Kitt-Tarozzi medium revealed microorganisms resembling tennis racket. These microorganisms are causative agents of the following disease:
A. Botulism. B. Diphtheria. C. Typhoid fever.
D. Salmonellosis. E. Dysentery.
A bacteriological laboratory studied the home-made dried fish which had caused a severe food poisoning. Microscopy of the culture grown on the Kitt-Tarozzi medium revealed
microorganisms resembling
a tennis racket. What is the most
likely diagnosis?
A. Botulism
B. Salmonellosis
C. Cholera
D. Dysentery
E. Typhoid fever
A bacteriological laboratory has been investigating a sample of homemade dried fish that was the cause of severe food poisoning. Microscopy of the culture inoculated in Kitt-Tarozzi medium revealed microorganisms resembling a tennis racket. What diagnosis can be made?
A. Botulism
B. Salmonellosis C. Cholera
D. Dysentery E. Typhoid fever
A patient has severe catarrhal symptoms. Material growth on Bordet-Gengou agar showed mercury-drop like colonies. Examination of the blood smears revealed some small
ovoid gram-negative
bacilli sized 1-3
microns. What
microorganisms
were isolated?
A. Bordetella
B. Corynebacteria
C. Mycobacteria
D. Meningococcus
E. Brucella
During bacteriological examination of sputum of a child with choking cough and fever there were revealed glossy smooth colonies growing on casein-charcoal agar and reminding of mercury drops. Microscopic examination revealed short Gram-negative bacteria. What microorganism was secured from the sputum?
A. Bordetella pertussis
B. Haemophylus influenzae
C. Corynebacterium dyphtheriae
D.Klebsiella pneumoniae
E. Streptococcus pyogenes
On the base of the clinical data a child was diagnosed with atypical pneumonia resistant to the effects of beta-lactam antibiotics. The patient’s sputum was cultured and incubated in a special medium, which resulted in growth of microorganisms forming microscopic colonies with a dense center (looking like fried eggs). What microorganism caused the disease?
