title: Frequency of amoebiasis and other intestinal parasitoses in a settlement in Ilhéus City, State of Bahia, Brazil.
abstract: BACKGROUND
  This study evaluated the frequency of intestinal parasites, emphasizing the identification and differentiation of Entamoeba spp.
  
  
  METHODS
  Multiplex polymerase chain reaction (PCR), coproantigen tests and morphometric analysis were performed for Entamoeba spp. differentiation.
  
  
  RESULTS
  The overall frequency of intestinal parasites was 65%. Entamoeba histolytica was detected by the coproantigen test, and the PCR showed that Entamoeba dispar predominated in the population. In contrast, morphometric analysis was important for identifying Entamoeba hartmanni.
  
  
  CONCLUSIONS
  It is possible to identify the causative agent of amoebiasis and to differentiate this agent from other species by combining techniques.
