Questions and Answers

What differentiates formig from staph on blood agar in terms of their ability to lyse RBCs?

  • Staph causes seethrough lysis, while formig causes incomplete lysis.
  • Formig lyses RBCs incompletely, while staph can lyse RBCs completely.
  • Formig causes no lysis of RBCs, while staph can cause partial lysis.
  • Formig can lyse RBCs completely, while staph can only cause incomplete lysis. (correct)

Why is it important for patients to finish the course of antibiotics (ABX) as prescribed?

  • Incomplete ABX course can cause generalized systemic symptoms.
  • Discontinuation of ABX will lead to recurrent infections with different bacteria.
  • Discontinuation of ABX can lead to prolonged illness and potential kidney damage. (correct)
  • ABX resistance increases with incomplete courses of treatment.
