Culture method, step 1 and 2. Anaerobic cultivation.

1. The aim of culture method step 2 is

• isolation (accumulation) of pure culture

• morphotinctorial features evaluation

• oxidative & fermentative

• fermentative

2. The aim of microscopic study of gram-stained smears obtained from single colonies is

• morphotinctorial features evaluation

• chemoheterotrophs

• lag phase, log (exponential) phase, stationary phase, death phase

• type III secretion system (T3SS)

3. The aim of single colonies spreading from petri dish to agar slant is

• isolation (accumulation) of pure culture

• chemoheterotrophs

• Gas Packs

• clostridia

4. The metabolism type in obligate (strict) anaerobes is

• fermentative

• oxidative

• Fortner's method

• mechanical oxygen removal (displacement of oxygen with other gases)

5. The metabolism type in facultative anaerobes (= facultative aerobes) is

• oxidative & fermentative

• type III secretion system (T3SS)

• anaerobic jar

• generation time

6. The metabolism type in the majority of clinically significant bacteria is

• chemoheterotrophs

• oxidative & fermentative

• aerotolerance

• isolation (accumulation) of pure bacterial culture

7. The nutrition type in the majority of clinically significant bacteria is

• chemoheterotrophs

• aerotolerance

• colony morphology

• auxotrophy

8. The phase of bacterial growth is

• lag phase, log (exponential) phase, stationary phase, death phase

•  cytoplasmic membrane

• facultative anaerobes

• ribosomes

9. Selective delivery of substances into bacterial cell is mainly provided by

•  cell wall

• nucleoid

• cytoplasmic membrane

• mesosomes

10. Transport of effector bacterial molecules into eukaryotic cells is provides by

• facilitated diffusion

• active transport

• facilitated diffusion

• type III secretion system (T3SS)
