All of the following are related to bacterial infection. Which would prevent all of the others?
a. Vaccination against fimbriae
b. Phagocytosis
c. Inhibition of phagocytic digestion
d. Destruction of adhesins
e. Alteration of cytoskeleton

Step 1: Understand the role of each option in bacterial infection. Vaccination against fimbriae (option a) aims to prevent bacteria from attaching to host cells by targeting fimbriae, which are adhesion structures.
Step 2: Recognize that phagocytosis (option b) is a host defense mechanism where immune cells engulf bacteria, but it occurs after bacteria have adhered and invaded tissues.
Step 3: Note that inhibition of phagocytic digestion (option c) is a bacterial strategy to survive inside immune cells, so it does not prevent initial infection but affects later immune response.
Step 4: Destruction of adhesins (option d) directly targets bacterial molecules responsible for attachment, similar to vaccination against fimbriae, but it acts on the bacterial components themselves.
Step 5: Alteration of the cytoskeleton (option e) refers to bacterial manipulation of host cell structure after attachment, so it does not prevent initial bacterial adhesion or infection.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Bacterial Adhesion and Adhesins

Bacterial adhesion is the initial step in infection where bacteria attach to host cells using surface structures called adhesins, such as fimbriae. Preventing adhesion blocks colonization and subsequent infection, making it a critical target for interventions like vaccines.

Phagocytosis and Host Immune Defense

Phagocytosis is a process where immune cells engulf and destroy pathogens. It is a key defense mechanism against bacterial infections, but some bacteria can evade this by inhibiting phagocytic digestion or altering host cell functions.

Vaccination and Immune Prevention

Vaccination stimulates the immune system to recognize and neutralize specific bacterial components, such as fimbriae, preventing bacteria from adhering and establishing infection. This proactive approach can block infection before other immune responses are needed.
