Students will be able to prepare microscopic preparates, including diagnostic staining, to determine on the morfology basis the main genuses of yeasts and micromycets. They will know how to interpret ENTEROtest and on the basis of thein own measurement they will be able to calculate the specific growth rate of model microorganisms. They will master the priciples of aseptic work and to prepare basic types of the growth media. |
