Description
Summary:Intestinal parasitic infections are one of the most common infectious diseases worldwide, particularly in developing countries. A distinct group at increased risk of infection is military personnel deployed overseas for extended periods, typically six months at a time. The aim of this study was to determine the prevalence of Blastocystis spp. and other intestinal parasites in Polish military personnel returning from deployments to Lebanon (n = 206) and Iraq (n = 220). In this group of subjects, we found Blastocystis spp. (13.6%), Dientamoeba fragilis (3.3%), Entamoeba coli (0.9%), and Endolimax nana (0.5%). Entamoeba histolytica sensu lato and Chilomastix mesnili infections were detected only in one soldier returning from Lebanon and Iraq, respectively. Blastocystis subtype (ST) 3 was predominant in soldiers returning from Lebanon, followed by ST2 and ST1. ST1 infection was predominant in soldiers returning from Iraq, followed by ST3 and ST2. Our study affirms that, deployment abroad is of no influence of the prevalence of parasitic protozoa. However, it would be worth to monitor parasite infection in military personnel returning from tropical zone even if they have no actual symptoms. In addition, it is very important to determine the subtypes of Blastocystis—this may help to clearly define their pathogenicity, especially considering the scarcity of studies on Blastocystis genotypes in Iraqi and Lebanese residents.
