School children between 6 to 12 years of age were studied for the presence of Entamoeba histolytica cysts in a period of 6 months, form March to August 1980. Fecal specimens collected form urban and rural children were examined first by the Lugol stained technique and then by the Faust's iron alum hematoxylin method. A total of 731 specimens were examined. Of these 26.9 per cent, 197 specimens, harbored the cysts. The demonstration rate for the cysts by age group varied from 19.6 to 43.5 per cent. The demonstration rate in boys was 24.4 per cent and in girls 29.8 per cent. Similarily, the rate in urban and rural area was 32.4 and 24.1 per cent, respectively. It was found in the present study that there were no significant differences in the age and sex rates of demonstration between urban and rural children but there was a predominance of the small race of Entamoeba histolytica over the large race.

For seven years from 1962 to 1968, fecal specimens of the patients were examined not only for the discovery of intestinal protozoa and helminths, but also to provie data on the incidence of intestinal parasites among the residents of Kyungpook Province, Korea. The Formalin-ether sedimentation, Lugol solution, and Heidenhain's iron-hematoxylin stained films were prepared for the recovery of intestinal parasites. Of 2,414 samples of feces examined, 35.7 percent were found to be infected with one or more species of protozoa. Among six species of protozoa detected, Entamoeba coli was observed most frequently(15.3%) followed by Entamoeba histolytica (11.9%), and then the Enteromonas hominis least often(1 case). For the survey of helminth, of a total of 5,288 fecal specimens examined, 86.7 percent were positive for one or more species of helminths. Trichocephalus trichiurus revealed the highest infection rate (83.6%), while Trichostrongylus orientalis was next (61.6%), and Ascaris lumbricoides was unexpectedly low(40.9%). The incidence for hookworm and Clonorchis sinensis was 22.4 percent and 29.8 percent respectively. Triple infections were found more frequently than double infections, and mixed infections of six or more species of helminths were observed in 3.8 percent of specimens.

In this study, we aimed to investigate the incidence of Dientamoeba fragilis with different diagnostic methods in patients with gastrointestinal symptoms and determine the sensitivity and specificity of existing diagnostic methods. Fecal samples collected from 101 patients with gastrointestinal complaints (especially upper abdominal pain, abdominal and pelvic pain, nausea and vomiting, gastroenteritis and colitis, unexplained fever and diarrhea) and 20 control cases from various clinics were included in the study. Samples were first examined with native-Lugol (N-L) method and cultured in Robinson medium. All 121 stool and culture samples were stained with iron hematoxylin stain (IHS) and trichrome stain (TS) methods and examined by PCR and QPCR for D.fragilis. Among 121 stool samples 13 (10.7%), 2 (1.7%), 7 (5.7%) 13 (10.7%), and 7 (5.8%), 4 (3.3%), 2 (1.7%), 3 (2.5%) of cultured samples were determined positive with IHS, TS, PCR, QPCR respectively. Fifteen of the 121 stool samples were determined as diarrheal. All diarrheal stool samples were negative with IHS and TS. One of the diarrheal stools and 6 (4.9%) of the non-diarrheal stools were positive by PCR. All of the diarrheal stools were negative. Thirteen of the non-diarrheal stool samples (10.7%) were positive by QPCR. When the QPCR method was considered as gold standard, sensitivity and specificity values were determined as 46% and 93% in IHS, 0% and 99% in TS, 54% and 100% by PCR and sensitivity and specificity values were 67% and 96% in IHS, 33% and 98% in TS, 67% and 100% by PCR among cultured stool samples. As a result, it was determined that there was a statistically significant difference between the samples of the patients and the control groups and the sensitivity and specificity of the conventional and molecular methods (IHS, TS, PCR and QPCR) determined in this study supported the results of other compared studies. It has been determined that staining methods used for the diagnosis of D.fragilis gave false positivite or negativite results. In addition, the QPCR method is more advantageous in terms of time saving for the diagnosis and initiation of the treatment and in cases where QPCR is not available, IHS and conventional PCR methods should be used together. In our opinion, this study will contribute to the results of epidemiological and scientific studies on D.fragilis in Turkey.
