The present study was aimed at carrying out a cross-sectional copromicroscopic survey of helminths and intestinal protozoa in immigrants in Naples (southern Italy). Between October 2008 and November 2009, a total of 514 immigrants were tested comparing the FLOTAC dual technique and the ethyl acetate concentration technique. Combined results of the two techniques served as a diagnostic ‘gold’ standard and revealed an overall prevalence of parasitic infections of 61.9% (318/514). The ethyl acetate concentration technique detected a low number of positive results (49.0%) and this was confirmed for each helminth/protozoa species detected. Among helminths, Trichuris trichiura (3.9%), hookworms (3.7%) and Ascaris lumbricoides (1.4%) were the most prevalent.

As regard to pathogenic protozoa, Blastocystis hominis was the most commonly detected (52.7%), followed by Entamoeba histolytica/Entamoeba dispar/Entamoeba moshkovskii (11.9%) and Giardia duodenalis (4.5%). Several issues concerning diagnosis, epidemiology and public health impact of parasitic infections in immigrants are offered for discussion.

Abstract

The present study was aimed at carrying out a cross-sectional copromicroscopic survey of helminths and intestinal protozoa in immigrants in Naples (southern Italy). Between October 2008 and November 2009, a total of 514 immigrants were tested comparing the FLOTAC dual technique and the ethyl acetate concentration technique. Combined results of the two techniques served as a diagnostic ‘gold’ standard and revealed an overall prevalence of parasitic infections of 61.9% (318/514). The ethyl acetate concentration technique detected a low number of positive results (49.0%) and this was confirmed for each helminth/protozoa species detected. Among helminths, Trichuris trichiura (3.9%), hookworms (3.7%) and Ascaris lumbricoides (1.4%) were the most prevalent. Strongyloides stercoralis (0.4%), Enterobius vermicularis (0.4%), Schistosoma mansoni (1.0%), Hymenolepis nana (1.6%) and Taenia spp. (0.2%) were also found, as well as zoonotic helminths, as Trichostrongylus spp. (0.8%) and Dicrocoelium dendriticum (0.8%). As regard to pathogenic protozoa, Blastocystis hominis was the most commonly detected (52.7%), followed by Entamoeba histolytica/Entamoeba dispar/Entamoeba moshkovskii (11.9%) and Giardia duodenalis (4.5%). Several issues concerning diagnosis, epidemiology and public health impact of parasitic infections in immigrants are offered for discussion. In conclusion, the present paper pointed out the need of better diagnosis and cure of the immigrants population in order to improve access to health care of this neglected and marginalised population group, for its own protection and care.
