A. *Staphilococci.
B. Diplococci.
C. Micrococci.
D. Streptococci.
E. Tetracocci.

18. A child with the diagnosis of staphylococcal sepsis was admitted to a hospital. What nutrient medium should be used for patient's blood inoculation to isolate the causative agent of this disease?

Ploskirev's medium.
Meat peptone broth.
* Glucose peptone broth.
D. Buchin's medium.

A 55-year-old patient is hospitalized to a surgical department with suspicion of sepsis. Choose the specimen which should be obtained for examination.

A. Liquor.

B. *Blood.
C. Urine.
D.Pus.
E. Lymph node punctate.

112. Feces of a child with enteritis are resuspended in isotonic solution of sodium chloride, and a suspension drops applied onto selective medium: 10 % milk-salt or yolk-salt agar. What microorganisms are supposed to be isolated?

E. coli.
Klebsiella
*Staphylococci.
Streptococci.
Enterococci.

* Staphylococcal etiology of infection was confirmed with bacteriological examination at patient with furunculosis. What basic method of microbiological diagnostics was used in this case?

Allergic
*Bacteriological
Serological
Microscopic
Biological

*05* *08* b-12 Examination of a patient with pustular skin lesions allowed to isolate a causative agent that formon the blood agar roundish yellow middle-sized colonies surrouded by hemolysis zone. Smears from colonies contain irregular-shaped clusters of gram-positive cocci. The culture is oxydase- and catalase-positive, ferments mannitol and synthesizes plasmocoagulase. What causative agent was isolated?

Streptococcus agalactiae
*Staphylococcus aureus
Staphylococcus saprophyticus
Staphylococcus epidermidis
Streptococcus pyogenes

*Post –operative purulent complications into surgery wound took place in a surgical department. Microscopy of wound discharge revealed gram-positive spherical bacteria arranged in grape-like clusters. For differentiation of what microorganisms was coagulase test used in laboratory?

*Staphylococcus aureus from Staphylococcus epidermidis
Streptococcus pyogenes from Staphylococcus aureus
Staphylococcus epidermidis from Neisseria meningitidis
Streptococcus pyogenes from Enterococcus faecalis
Neisseria meningitidis from Streptococcus pneumonia

*b-12 A man, 65 years old, has suffered from purulent abscess on his neck. A culture of gram-positive cocci was isolated that possessed plasmocoagulase activity.

*Staphylococcus aureus
Staphylococcus epidermidis
Staphylococcus saprophyticus
Streptococcus pyogenes

“04” 8. Microbiology examinations are carried out in the neonatal department of a maternity hospital because of the suspicion of a hospital infection. S. aureus from several children and some things was isolated. What properties of isolated cultures should be examined to determine the source of infection?

Biochemical activity.
Chrornogenesis.
Antigenic structure.
*Phage type.
Antibiotic sensitivity.

“06” 23. Cases of suppurative postoperative complications caused by staphylococcus have increased in a surgical unit. Which test should be used to determine the source of infection?

A. Drugs susceptibility test.
B. Serotyping test.
C. Aggression enzymes determination.
D.Toxin production.
E. *Phage typing.

b-12 In the surgical department of a hospital there was an outbreak of hospital infection that showed itself in often postoperative wound abscesses. Bacteriological examination of pus revealed aurococcus. What examination shall be conducted to find out the source of this causative agent among the department personnel?
