Why are encapsolated bacteria generally more pathogenic than un-capsolated strains.
a. Because capsule allows the organism to hide in the body of the host.
b. because the capsule causes the phagocyte to mutate c. because the capsule protects bacteria from host immune cells
d. because the capsule kills the phagocytes
e. because the capsule stimulates a potent immune response in the host.
Why are Pseudomonas aeruginosa infections difficult to treat?
