why do so many eukaryotic pathogens cause highly refractory and long-term chronic infections that are difficult to treat in contrast with prokaryotic pathogens?
a. Eukaryotic pathogens are selfish: they only think about themselves and don`t spare the host, while bacterial parasites are more gentle and almost never kill their host
b.Americans do not need to worry about any eukaryotic pathogens, because they are so rare, nobody ever gets infected with them
c. eukaryotic pathogens were around less time than bacteria, so they did not have sufficient time to coevolve with the human host and lose its virulence (because this happens 100% of the time)
d. humans are also eukaryotic, thus the pathogen and host share many of the same enzymes and structures and it is hard to pick a good drug target
e. because most doctors just are not that familiar with the eukaryotic parasites, so they are often overlooked
