Document Summary
Lists various ways to grow cultures and sterilize materials. We looked at cultures of microorganisms from varying surfaces such as floor, fingers, hair, sick, clothes, air, dirt, and nose. Vocabulary: pathogenic disease-causing (for humans) microorganisms, minority of microorganisms nosocomial hospital acquired infections from nonpathogenic microogranisms infecting a sick person. Washing hands is important in preventing the spread of microorganisms. Microorganisms (normal flora) are always present but not harmful. Transient flora are temporary and either die or leave quickly. Results: dial and ivory better than bacdown and water only. We learned how to describe colony morphology of microorganisms grown on agar (colony morphology dependent on growth medium) with the table on page 14. Vocabulary: colony can come from one or more cells colony morphology visible properties of a colony contaminant an unwanted organism which has been accidentally introduced into the colony.
