The antibiotic susceptibility testing results of Staphylococcus showed zones of inhibition (absence of growth on zones) around discs of Penicilin, Teracycline, chloramphenicol, this means that
a) S. aueres is resistant to all these antibiotics.
b) S. aueres is susceptible to all these antibiotics.
c) susceptible to only a couple of them
d) neither are the correct choices
Where do true antibiotics come from in nature? Explain why this is the case.
Anthrax is

O 3) a disease that, in humans, can cause a rapidly fatal toxemia and septicemia.
4) transmitted by contact, inhalation, and ingestion.
