А. Meningococcus.

В. Staphylococcus.

C. Streptococcus.

D. Pneumococcus.

Е. Gonococcus.

78. A group of people who had been in contact were tested for chronic type of gonorrhea. They were administered serological research of blood serum with complement fixation test and skin allergic test with gonococcal allergen. Why were those two methods used?

А. They allow choosing patients for more accurate research.

В. They are the most informative for the confirmation of diagnosis.

C. They allow making proper diagnosis in short terms.

D. They can be performed in any hospital.

Е. This is doctor’s wish.

79. A patient is tested for toxoplasmosis and chronic form of gonorrhea according to the rules of sterility. What reaction must be performed for the confirmation of the above mentioned diseases?

А. Complement fixation test.

В. IFT.

C. Immunoblotting.

D. PIHAT (passive indirect hemagglutination test).

Е. Counter electrophoresis.

80. Bacteriologist prepared a pus smear from the patient’s urethra by Gram staining. Microscopy revealed a great number of leucocytes, in the cytoplasm of which there were a lot of Gram-negative dyplococci in a shape of coffee beans. What is the result of this process?

А. Phagocytosis.

В. Metabolism.

C. Formation of capsule.

D. Formation of spore.

Е. Malignation.

81. A 5-year-old patient complains of bad headache and vomiting. Objectively: rigidity of the occipital muscles, occasional vomiting, nausea, herpes on the face, and fever. What material can prove the preliminary diagnosis of cerebrospinal meningitis?

В. Identification of N. meningitidis in urine culture.

C. Identification of N. meningitidis in stool culture.

D. Research of vomiting mass.

Е. Identification of N. meningitidis on the mucous membrane of urogenital system.

82. During bacteriological investigation of pyogenic discharge from urethra there were discovered Gram-negative coffee-bean shaped bacteria which could ferment glucose into acid and were settled inside cytoplasm of leucocytes. What disease can these microorganisms cause?

А. Gonorrhea.

В. Syphilis.

C. Veneral lymphogranulomatosis.

D. Soft chancre.

Е. Meloidosis.

83. Light blue colonies grew on special enriched media after having been inoculated from the urethra. Microscopy revealed Gram-negative coffee bean shaped diplococci. What disease can these microorganisms cause?

А. Chlamydiosis.

В. Gonorrhea.

C. Syphilis.

D. Tularaemia.

Е. Meliodosis.

84. Smear was taken from a patient suspected of chronic form of gonorrhoea. Three days earlier the patient had treated himself with penicillin. L-forms of gonococcus are observed under the microscope. What is the effect of penicillin on gonococcus?

А. It destroys protein synthesis.

В. It destroys cell wall synthesis.

C. It destroys aminoacid synthesis.

D. It changes penetrative function of cytoplasm membrane.

Е. It destroys adhesion.
