How might culture age affect the results of a spore stain? O If the bacterial culture is too young, the bacteria may not yet have formed spores leaving only vegetative cel: to view. O If the bacterial culture is too old the capsule will be broken down O If the bacterial culture is too old the gram positive cells may stain gram variable or gram negative leading to erroneous results O If the bacterial culture is too old, the vegetative cells may have all release their spores and dies, leaving only spores to view. O If the bacterial culture is too young the capsule will not be formed yet Question 4 How does a capsule contribute to pathogenicity? O prevent phagocytes from adhering to the cell wall, O The capsule induces the immune system to attack itself O They can prevent neutrophils from killing engulfed bacteria, O can prevent bacterial cell lysis, among other traits, increase survivability of the bacteria that produce them, and enable them to cause disease in a host. O They cause the bacteria to be antibiotic resistant
