This means serotonin secretion not only serves to increase the spread of enteamoebas by giving the host diarrhea but also serves to coordinate their behaviour according to their population density, a phenomenon known as quorum sensing.
Isto significa que a secreción de serotonina non só serve para incrementar a diseminación de entoamoebas orixinando diarrea no hóspede, senón tamén para coordinar o seu comportamento de acordo coa densidade da súa poboación, un fenómeno chamado percepción do quórum (quorum sensing).
