Only the host's susceptibility to the pathogenic agent D. A case of Strep throat D. It allows us to grow large amounts of bacteria to conduct further biochemical tests. The idea that internal parasites can lose cellular structures such as cell walls over time because they do not need them if they live within host cells D. How do I change the email address I use to access Smartwork5? Borrelia burgdorferi would have to be isolated from a host suffering from Lyme disease and grown in pure culture. The rabbit will contain pure cultures of the microbe.
