[Emergent infectious diseases: a new problem?].
Are the emergent pathogenic microbes, persistent bacteria that have changed their virulence or new diagnostic techniques now allow their recognition? Or, have they found a new possibility of transmission due to ecological, social or cultural changes? The present Editorial analyses the geographical distribution, features and host factors that favor infections by Helicobacter pylorii, Enterohemorrhagic E. Coli, invasive Streptococcus pyogenes and Borrelia Burgdorferi. The surveillance and care of infections caused by emergent germs requires laboratory learning programs as those established in the United States.
