Humans Have Immune Systems in Which Lymph Nodes Are Important

question 88

Multiple Choice

Humans have immune systems in which lymph nodes are important, because many phagocytes and lymphocytes reside there. Given that a successful infection by S. schenkii damages lymph nodes themselves, which of the following is most probable?

• A)The hyphae secrete antibiotics, which increases the ability of the infected human to tolerate the fungus.
• B)Their conversion from yeast to hyphal morphology allows such fast growth that the body's defences are at least temporarily overwhelmed.
• C)Defensive cells of humans cannot detect foreign cells that are covered with cell walls composed of cellulose.
• D)Given that most fungal pathogens attack plants, human defences are simply not adapted to seek out and destroy fungi.
• E)Given that most fungal pathogens of humans infect only the skin, human defences are not adapted to seek out and destroy systemic fungal infections.
