Answer:
Some may cause diseases.
Explanation:
Eubacteria and Archaebacteria differ by a few characteristics:
It has been found that these do reproduce quickly and sometimes in humans. It may cause some danger in some situations as cholera and vibrio are virulent and dangerous diseases to humans.
In other aspects it does not pose a threat to human health in the case of Lactobacillus.
Archaebacteria on the other hand is not known use humans as a host but they may infect other Eubacteria and cause them to be negatively affected.
Fast reproduction/division rate means that the infection of the bacteria cannot be slowed down or stopped before the organism it has taken over becomes affected.
