Gonococci
1. Bacteriological examination of purulent discharges from the urethra revealed gram-negative bacteria looking like coffee beans. They were localized in the leukocytes and could decompose glucose and maltose to acid. These are the causative agents of the following disease:
A. Gonorrhoea B. Syphilis C. Melioidosis
D. Soft chancre E. Veneral lymphogranulomatosis
2. Gramnegative bin-shaped diplococcus inside and outside of leucocytes were detected on bacteriological examination of the purulent exudates from the cervix of the uterus. Name the causative agent of purulent inflammation of the cervix of the uterus.
A. Haemophilus vaginalis B. Chlamidia trachomatis
C. Calymmatobacterium granulomatis
D. Neisseria gonorrhoeae E. Trichomonas vaginalis
3. Bacteriological analysis of purulent discharges from urethra revealed presence of gram-negative bacteria resembling of coffee beans, which were able to decompose glucose and maltose into acid. They were found in the leukocytes. These bacteria are causative agents of the following disease:
A. Gonorrhoea B. Syphilis C. Melioidosis
D. Ulcul molle E. Venereal lymphogranulomatosis
4. Bacteriological examination of purulent discharges from urethra revealed some bacteria that had negative Gram’s stain, resembled of coffee corns, decomposed glucose and maltose up to acid. They were located in leukocutes. What disease do they cause?
A. Gonorrhea B. Syphilis C. Pseudocholera
D. Soft chancre E. Venereal lymphogranulomatosis
5. Microscopy of a female patient’s swabs made from vaginal secretion revealed gramnegative bean-shaped diplococci. What provisional diagnosis can be made?
A. Gonorrhoea B. Syphilis C. Clamidiosis

D. Streptococci E. Staphylococci
7. A newborn child has hyperemia, edema of mouth mucous membrane, small erosions with viscous muco-purulent discharge. Examination of muco-pus smears reveals a great number of leukocytes containing gram-negative diplococci. The same microorganisms can be found outside the leukocytes.
