*111. Cholecystic infection was caused by microorganisms of spherical oblong form situated in pairs or short chains. On the basis of biological properties the bacteria were referred to group D streptococci. What is their name?
A. β-hemolytic streptococci.
B. α-hemolytic streptococci.
C. Pyogenic streptococci.

*04* *2012* 115.b-12 Gram-positive diplococci with some pointed ends were revealed during the examination of a patient's sputum due to suspicious pneumonia. Which microorganism is the most likely to cause the disease?

Staphylocccocus aureus
Neisseria meningitidis.
Klebsiella pneumoniae.
Neisseria gonorrhoeae.
*Streptococcus pneumoniae.

85. Microscopy of the sputum of a patient with croupous pneumonia revealed numerous Gram-positive lanceolate diplococci surrounded by a capsule. Name the most likely causative agent.

Chlamidia pneumoniae.
Klebsiella pneumoniae.
C. *Streptococcus pneumoniae.
Staphylococcus aureus
Escherichia coli.

*08* b-12 Blood of a patient with presumable sepsis was inoculated into sugar broth. There appeared bottom sediment. Repeated inoculation into blood agar caused growth of small transparent round colonies surrounded by hemolysis zone. Examination of a smear from the sediment revealed gram-positive cocci in form of long chains. What microorganisms are present in blood of this patient?

1. 
   Sarcina
   
2. 
   Staphylococci
   
3. 
   Tetracocci
   
4. 
   Micrococci
   
5. 
   *Streptococci
   

A 12-year-old boy after angina has rheumatic damage of heart. Every successive streptococcal infection worsens the condition of the patient. What preparation is expedient to use for the prevention of complications?

A. Streptococcic toxoid.
B. *Benzylpenicillin sodium salt.
C. Streptococcic bacteriophage.
D. Donor γ-globulin.
E. Autovaccine.

b-12 A 7 year old child often suffers from streprococcic angina. Doctor suspected development of rheumatism and administered serological examination. The provisional diagnosis will be most probably confirmed by presence of antibodies to the following streptococcic antigen:
