Every pathogen produces its own proteins and wastes (created during replication). Both of these can irritate the cells of a host (example: human being). The pathogen's proteins and wastes can cause nausea, vomiting, pus at wound sites, etc. Once the pathogen is stopped, such as with an antibiotic for bacterial pathogens, the "bug" no longer produces the proteins and its waste, so some symptoms begin to decrease as soon as the correct medication is introduced.

Pathogens such as a bacterium or a virus can influence the growth rate of the host organism. Virus (not really an organism) can infect a bacterium and integrate their genetic material. This changes the homeostasis of the bacteria, because viral proteins would be start producing by the host. hence the host can not grow as a normal organism after infection.
Primary Pathogens are the microorganisms that cause diseases in healthy individual. Opportunistic Pathogens are the microorganisms that are ordinarily in contact with the host and cause disease when the host's resistance is low.
The immune system needs to destroy the pathogens. Other wise the pathogens will multiply in the body of host. The pathogens will multiply by geometrical proportion. With in very short time the pathogens will occupy the whole body. You can no longer survive in that case.
intracellular pathogens can only replicate inside a host cell, whereas extracellular pathogens can replicate independent of the host
Bacteria that cause disease are called pathogens. ( as are any other microorganism that causes disease). Pathogens cause disease either by 1) preventing host tissues from functioning properly. i.e stop oraganelles in the cells from working or by reproducing and bursting cells. 2) Producing toxins which destroy host tissues.
Many pathogens outside the body can be killed with heat or chemicals. Inside the body, pathogens can sometimes be killed with medicine.
intracellular pathogens can only replicate inside a host cell, whereas extracellular pathogens can replicate independent of the host
Yes, pathogens are agents capable of causing infections or some types of diseases. Pathogens are normally on our skin and any objects without causing problems. Not all pathogens succeed in their goal to find a host, but many pathogens do.
your body produces antigens to fight against the pathogens and imune you agaist diseases.

I think it's because eukaryotic pathogens are more similar to host cells. So, if there are more similarities, it is harder to treat.

we have some germs but if we get sick the germs go through the mouth and pathogens grow because the sick person care about you than there germs go to your germs yuck!

Because pathogens cause disease or illness to their host so that's mean it threat the body.
