    A patient complained about a carbuncle on his face. Examination results: neither dense nor painful edema of subcutaneous cellular tissue, there is black crust in the middle of the carbuncle and peripheral vesicular rash around it. Bacteriological examination revealed presence of immobile streptobacilli able of capsulation. What microorganisms are causative agents of this disease?
    
    1. 
       Bacillus antracis
       
    2. 
       Staptylococcus aureus
       
    3. 
       Bacillus anthracoides
       
    4. 
       Bacillus megaterium
       
    5. 
       Bacillus subtilis

    A 34 year old male patient consulted a doctor about face carbuncle. Objectively: a loose, painless edema of hypodermic tissue; black crust in the center of carbuncle, vesicular rash around it. Microbiological examination revealed static streptobacilli capable of capsule building. What microorganisms are the causative agents of this disease?
    

A. Bacillus antracis B. Staptylococcus aureus
C. Bacillus subtilis D. Bacillus anthracoides
E. Bacillus megaterium
