Question

You are assisting a microbiologist with identifying pathogens based on several methods. You are assigned a specimen isolated from a patient's infected wound. Upon a biochemical analysis, the organism contains cells and a nucleus. Under the microscope you observe fine filamentous cells. You apply a stain that is sensitive to peptidoglycan, but it leaves no mark. Another biochemical assay reveals no chitin, but it is sensitive for cellulose. Under further examination, you find tiny egg-shaped forms that appear to be releasing spores. Which taxa best matches the description of the organism? Select one: a. Phylum Ascomycota b. Phylum apicomplexa c. Phylum Oomycota d. Virus e. Bacteria
