The stool samples obtained from 94 patients with gastrointestinal symptoms and 109 asymptomatic individuals, who checked in due to other reasons, admitted at a major hospital in Ankara, Turkey were examined with native Lugol's iodine, trichrome, and Kinyoun's acid-fast stainings for parasitology examinations and with in vitro culture method for detection of Blastocystis. In a total of 203 stool samples tested, native Lugol's iodine and trichrome stainings could detect 12 (5.9%) and 20 (9.9%) positive samples for Blastocystis, respectively. Conversely, culture method could detect 66 (32.5%) positive samples, and this method was more sensitive compared to the both microscopic examinations (p < 0.001). Among 66 positive samples for Blastocystis, 27 were from symptomatic patients and 39 were from asymptomatic group. Subtypes (STs) were determined by PCR using seven different sequence-tagged site primers. ST3 was the most dominant in both symptomatic and asymptomatic groups and followed by ST1 or ST2. There were mixed infections with STs 1 and 2 or STs 1 and 3 in nine isolates. There was no statistical significance of the distribution of Blastocystis sp. subtypes between symptomatic and asymptomatic individuals (p > 0.05).

AbstractThis study was conducted to investigate the prevalence of Blastocystis spp. and its subtypes (STs) in North Cyprus; and to evaluate the presence of this parasite and its STs with respect to demographic, socioeconomic, and epidemiological factors, as well as gastrointestinal symptoms. Stool samples were collected from 230 volunteers. Each participant also filled out a questionnaire. The samples were examined microscopically by native-Lugol and trichrome methods and further tested by polymerase chain reaction (PCR) and sequencing. Prevalence of Blastocystis spp. infection was found to be 10.5%, 10.5%, and 27.8%, by direct microscopy, trichrome method, and PCR, respectively. No other parasites were detected in the specimens except Giardia spp. (n = 2; 0.8%) and Entamoeba coli (n = 1; 0.4%). The most common Blastocystis STs were ST3 (20; 31.2%), ST2 (18; 28.2%), ST1 (8; 12.5%), and ST4 (7; 11%); whereas other STs were identified as ST6 (3; 4.7%), ST7 (2; 3.2%), and non-ST (6; 9.4%). Presence of Blastocystis spp. and its STs was not significantly related to any of the demographic, socioeconomic, and epidemiological factors. Furthermore, no significant association of Blastocystis spp. and its STs with gastrointestinal symptoms was found. This study is the first investigation of the epidemiology of Blastocystis spp. in North Cyprus. Distribution of Blastocystis spp. and its STs among demographic, socioeconomic, and epidemiological factors showed complete homogeneity. Presence of the parasite and its STs was not significantly related with the gastrointestinal symptoms among symptomatic and asymptomatic individuals. These findings suggest that Blastocystis spp. may be part of the intestinal flora in humans.
