General microbiology

A. Pneumonic plaque B. Miliary tuberculosis
C. Influenza D. Ornithosis E. Sepsis
6. The laboratory for especially dangerous infections conducts microscopic examination of pathological material from a patient with suspected plague. The sample was stained by Burri-Gins technique. What property of the causative agent can be identified by this technique?
A. Capsule formation B. Spore formation
C. Acid resistance D. Alkali resistance
E. Presence of volutin granules
7. A puncture sample has been taken from the inguinal lymph nodes of a patient provisionally diagnosed with plague. The sample was inoculated into a hard nutrient medium. What shape will the colonies have, if the diagnosis is confirmed?
A. “Dewdrops”
B. “Shagreen leather”
C. “Lace handkerchief”
D. “Mercury drops”
E. “Lion’s mane”
8. Dwellers of a village noticed mass mortality of rats in some farms. It was suspected that the animals might have died from plague. What postmortal analyses should be conduced in order to establish the causative agent of the infection as soon as possible?
A. Ring precipitation reaction
B. Agglutination reaction C. Passive agglutination reaction
D. Neutralization reaction E. Complement-binding reaction
9. On the territory of a certain region the mass death of rodents was observed. It was assumed that it may be caused by plague agent. What serological reaction should be applied for quick determination of antigen of this epizootic agent?
A. Precipitation reaction B. Agglutination reaction
C. Reaction of passive hemagglutination
D. Bordet-Gengou test E. Neutralization reaction
10. On a certain territory mass death of rodents was registered. It was suspected that their death might have been caused by plague. What serological reaction should be applied for quick identification of antigen of the causative agent of this epizooty?
A. Precipitation B. Agglutination
C. Passive hemagglutination
D. Complement binding E. Neutralization

2 days after a hunter cut a ground squirrel’s body, he developed fever up to 39⁰C, his lymph nodes enlarged. Later he developed pneumonia with serohemorrhagic exudate that contained egg-shaped microorganisms with bipolar staining. What provisional diagnosis can be made in this case?
A. Brucellosis. B. Anthrax. C. Tetanus.
