It is carried in air droplets so enters through the airway and then into the lungs where it thrives on warm, damp environment.

When a pathogen enters the body what does it first encounter?

When a pathogen enters the body, it first encounters the body's physical and chemical barriers, primarily the skin and mucous membranes. These barriers provide a first line of defense by preventing the pathogen from entering deeper tissues. If the pathogen breaches these surfaces, it then encounters immune cells and proteins in the innate immune system, which act quickly to identify and combat the invader.

The pathogen tries to infect the body. The defense mechanism of the body resists the entry of the pathogen. If pathogen succeeds the infection is established and the body becomes sick.


If a pathogen is in drinking water what will it cause?

A very broad answer to a very broad question... A "pathogen" as defined by a dictionary would be, "any disease-producing agent, esp. a virus, bacterium, or other microorganism." First- a "pathogen" in drinking water will cause nothing unless someone or something drinks the water or if the "pathogen" enters the body/host by some other means... Second- even once the "pathogen" enters the body it may still cause nothing, as the quantity of the "pathogen" must be sufficient to cause the would be disease... Third- because a "pathogen" could be any one of millions of things, what disease would be caused by your hypothetical "pathogen in the drinking water" would depend entirely on what it is... You should seriously consider being more specific about your question. If you are interested in a specific pathogen and the associated disease, please try again.


What is active acquired immunity?

Active acquired immunity occurs when you get an infection by a pathogen (bacteria, virus) and your body responds and removes the pathogen and also your body makes "memory" cells. These cell remember this pathogen and when it enters your body again you remove it immediately. You are now immune to it. You usually don't notice this.


What happens when a pathogen enters in our body second and subsequent times?

During subsequent exposures to the same pathogen, the immune system is able to respond rapidly and activity reaches higher levels. The secondary immune responses can usually prevent disease, because the pathogen is detected, attacked and destroyed before symptoms appear.


Is TB a blood-borne pathogen?

Tuberculosis (TB) is caused by an airborne pathogen but is also carried in the saliva. Infected persons can spread the pathogen by breathing, coughing, kissing, or by sharing drinking cups / straws with saliva on them. Infected persons wear a mask until treatment has reduced the number of viruses found (the viral load). A recent case on an overseas flight meant all passengers needed screened for TB and treated on a "just in case" basis because TB is highly contagious!
