Chemotroph
Autotroph
Heterotroph
Glucose may enter the bacterial cell in modified form against gradient concentration. Such type of bacterial nutrition is named:
facilitated diffusion
Active transport
Translocation groups
Passive diffusion
Ion pumps
Laboratory assistant obtains clinical material collected from patient with intestine infection. He should detect and identify the pathogen in sample. Microscopy investigation was not enough to identify causative agents. What should he do to diagnose disease?
Make a conclusion based on clinical features
Inoculate material onto solid medium to obtain pure culture
Inoculate material onto liquid medium to detect growth characteristics of a germ
Infect laboratory animal to observe development of the same disease
Repeat microscopy investigation of another sample collected from the same patient
Select the correct statement:
Parasites grow and multiply without any lesion into the host;
The hetero (organo) trophs utilize inorganic compounds for synthesis of all carbon-containing compounds
Prototroph can not grow into minimal media
All medical important bacteria belong to chemoorganotrophs
Medical important bacteria belong to photoheterotrophs
Unknown bacterial strain uses organic compounds as source of carbon. Due to classification it belongs to:
Phototroph

Bacteria use sun light as source of energy
Bacteria have specific organoid for nutrition
Bacteria absorb nutrient in dissolved state by the whole surface
Bacteria can take any nutrient by endocytosis into cytoplasm
For isolation of pure culture of aerobic bacteria tested materials should be:
Inoculated onto agar media
Injected into laboratory animal;
Injected into chicken embryo
Inoculated into cell cultures
Inoculated into the liquid media
