2. A 3 m.o. baby has white film on the mucous membrane of his mouth, tongue and lips. A doctor suspected candidosis. What nutrient medium should be applied for inoculation of the material under examination in order to confirm this diagnosis?
A. Sabouraud’s B. Endo C. Jensen’s
D. Roux E. Clauberg’s
3. Examination of a child revealed some whitish spots looking like coagulated milk on the mucous membrane of his cheeks and tongue. Analysis of smears revealed gram-positive oval yeast-like cells. What causative agents are they?
A. Candida B. Staphylococci C. Diphtheria bacillus
D. Actinomycetes E. Fusobacteria
4. During examination of a 3-month old infant a pediatrician revealed that the baby’s oral mucosa and tongue were covered with a thick white deposit. In the material taken from the affected site a bacteriologist revealed the presence of yeast fungi giving the reasons for suspecting a fungal infection which occurs most often in children of this age, namely:
A. Candidiasis B. Favus C. Epidermophytosis
D. Actinomycosis E. Trichophytia
5. Microscopic examination of a Gramstained scrape from patient’s tongue revealed oval, round, elongated chains of dark-violet gemmating cells. What disease can be caused by this causative agent?
A. Candidosis B. Actinomycosis C. Diphtheria
D. Staphylococcic infection E. Streptococcic infection
6. A 9 y.o. child has been taking antibiotics on account of bronchopneumonia for a long time. There appeared pain and burning in the area of mucous membrane of his lips and tongue. Objectively: mucous membrane of lips and tongue has caseous and grey plaques that can be easily removed by a spatula leaving hyperemia foci on their spot. Microscopic examination of the plaques revealed mycelium. What is the most probable diagnosis?
A. Candidous cheilitis B. Exfoliative cheilitis
C. Leukoplakia D. Contactant allergic cheilitis
E. Manganotti’s cheilitis
7. After continuous treatment with antibiotics a patient got symptoms of stomatitis. Examination of specimens of oral mucous membrane revealed some oval polymorphous Gram-positive microorganisms arranged in clusters. What microorganism may be the cause of such manifestations?
A. С.albicans B. C.perfringens C. S.aureus
D. S.pyogenes E. H.pylori
8. After long-term antibiotic treatment a patient has developed whitish spots on the oral mucosa. Gram-positive oval budding cells were detected in the smear preparations. What causative agents were detected?
