Place the following steps for infection in order from first to last:
Invade tissues and obtain nutrients
Adhere to host tissues
Enter the host
Exit the host
Evade immune defenses

검증된 단계별 안내

Step 1: Identify the initial point of infection, which is when the microorganism gains access to the host. This corresponds to 'Enter the host'.

Step 2: Once inside, the microorganism must attach itself to the host cells to establish infection. This is 'Adhere to host tissues'.

Step 3: After adherence, the microorganism invades host tissues and obtains nutrients necessary for survival and multiplication. This step is 'Invade tissues and obtain nutrients'.

Step 4: To maintain infection, the microorganism must avoid being destroyed by the host's immune system. This is 'Evade immune defenses'.

Step 5: Finally, to spread the infection to new hosts, the microorganism must leave the current host. This is 'Exit the host'.

주요 개념

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

Stages of Microbial Infection

Infection progresses through distinct stages: entry into the host, adherence to host tissues, invasion and nutrient acquisition, evasion of immune defenses, and finally exit to spread. Understanding this sequence helps clarify how pathogens establish and maintain infection.

Adherence Mechanisms

Adherence is the process by which microbes attach to host cells using structures like pili or adhesins. This step is crucial for colonization and prevents pathogens from being washed away, enabling subsequent invasion and infection.

Immune Evasion Strategies

Pathogens employ various tactics to evade the host immune system, such as producing capsules, altering surface antigens, or secreting immune-modulating factors. This allows them to survive, multiply, and cause disease within the host.
