- Why can you see organisms now, but couldn’t see them when you first swabbed theplate? A bacterial colony consists of millions of bacterial cells which came from a singlebacterium. Which characteristic of life accounts for the formation of bacterial colonies?The use of the Gram stain in microbiology is important because it differentiates A) Bacteria from Archaea. B) prokaryotic from eukaryotic cells. C) bacterial cells with different types of cell walls. D) archaeal cells with different types of metabolism.What are bacteria? what is bacterial culture? how to grow bacteria and why? why are there so many bacteria on the keyboard?
- Are you able to distinguish between specific species of bacteria? Why, or why not? Which method for identifying bacteria is more precise, morphology or DNA sequence analysis, and why?Which of the microscope objectives is most satisfactory for studying bacteria? Why?Why do you suppose endospore-forming bacteria are commonly found in the soil? Suppose your unknown bacteria is a Gram-negative rod. You decide to perform an endospore stain, thinking it will help you with the identification of the organism. What will you see, and why?
- You a clinical lab worker. Your boss hands you a sample and asks you to identify the genus of bacteria in the sample. Using a microscope, you see long chains spherical bacteria, indicative of repeated divisions along one plane. To what genus do you think bacterial sample belongs? (Choose all that apply.) Group of answer choices Lactobacillus Lactococcus Staphylococcus Streptococcus CaulobacterDo the different species of bacteria appear the same or different from each other when grown in media? Do you think it would be easy to identify which of these three species you had just by descriptions of growth? Explain your answerWhich stain is most frequently used to distinguish differences between thecell walls of medically important bacteria?a. simple stain. c. Gram stainb. acridine orange stain d. negativestain
- You use the Gram staining procedure to stain a bacterium that lacks a cell wall. Would you consider the bacterium appear Gram positive or Gram negative ? And why?Based on the scientific name Streptococcus agalactiae, what morphology would you expect these cells to have?The laboratory that you are working in does not have a microscope or motility medium. Now, how will you determine if a disease-causing bacterium is plants is motile or non-motile?
