Rationale 3: A highly virulent microbe is one that can produce disease when present in minute numbers.
Rationale 4: Cell lining is not disrupted in this process.
Global Rationale: The ability of an organism to cause infection is its pathogenicity. Medications that can kill bacteria are called bacteriocidal. A highly virulent microbe is one that can produce disease when present in minute numbers. Cell lining is not disrupted in this process.
