Purpose: This study was done to determine the extent of Clonorchis sinensis infections as well as other parasitic infections and to determine the growth rate. Method: Analyzed test results were from 1,050 bowel samples taken at 3 public health subcenters located in Muju, North Jeolla Province during February and March 2007. Result: The results are summarized as follows; The egg positive rate by stool examination was 4.3%. Ascaris lumbricoides, Enterobius vermicularis, Clonorchis sinensis, Trichuris trichiura, Metagonimus, Paragonimus were detected. No one was infected with multiple parasites. Infection rate for Clonorchis sinensis was 3.5%. Statistical correlation to Clonorchis sinensis infection rate was as follows; Gender (p=0.001), Age (p=0.005), Proximity to a river (p<0.000), Drinking (p<0.000), Smoking (p=0.009), Cooking of freshwater fish (p<0.000), Confidence in subjective health status (p=0.032), Family history of infection (p=0.005), No significant correlation was found between Clonorchis sinensis infection rate and duration of stay (p=0.809) in the agricultural communities or between Clonorchis sinensis infection and knowledge of Clonorchis sinensis (p=0.113). Conclusion: The results of this survey show that there is a need to develop a program to test the condition of Clonorchis Sinensis infection and its growth rate in residents of rural communities.

Stool and cellotape anal swab examinations were carried out in August 1997 on handicapped people at an institution located in Chorwon-gun, Kangwon-do, Korea. A total of 112 stool samples (78 males and 34 females) revealed three cases of Trichuris trichiura infection and one case of Enterobius vermicularis infection. Other helminth eggs were not detected. The overall prevalence rate was 35.7% (38.5% for males and 29.4% for females). More than two different kinds of parasites were found in 42.0% of the positive stool samples (17 cases). The infection rates for protozoan cysts are as follow : Entamoeba coli (25.0%), E. histoIUtica (1.8%), Endolinax nana (21.4%), Iodoamoeba butschlii (1.8%) and Giardia lamblia (0.9%). In cellotape anal swab examinations (165 samples), the prevalence rate of E. vemicularis was 20.6% (25.7% of males and 9.6% of females). In conclusion, the handicapped people in the institution showed higher infection rates of protozoan parasites and E. vemicularis, possibly due to more accessibility to the infection.

Paleoparasitological analysis was carried on 4 Merovingian skeletons, dated from the late-5th to the late-9th centuries, and recovered in the church of Saint-Martin-au-Val in Chartres (Center region, France). The corpses were buried in stone sarcophagi, which were still sealed at the time of excavation. Parasite marker extraction was conducted on sediment samples taken from the abdominal and pelvic regions, but also on samples taken from under the head and the feet as control samples. Microscopic observation revealed the presence of 3 gastrointestinal parasites, namely the roundworm (Ascaris lumbricoides), the whipworm (Trichuris trichiura) and the fish tapeworm (genus Diphyllobothrium). This analysis contributes to a better knowledge of the health status and the lifestyle of ancient medieval populations during the Merovingian period, for which very few paleoparasitological data were available, up until now. It demonstrates the presence of the fish tapeworm for the first time during this period.

The aim of this study is to determine the species of parasites that affected the inhabitants of the city of Acre on the coast of the eastern Mediterranean during the Ottoman Period. This is the first archaeological study of parasites in the Ottoman Empire. We analysed sediment from a latrine dating to the early 1800s for the presence of helminth eggs and protozoan parasites which caused dysentery. The samples were examined using light microscopy and enzyme-linked immunosorbent assay (ELISA) kits. We found evidence for roundworm (Ascaris lumbricoides), whipworm (Trichuris trichiura), fish tapeworm (Dibothriocephalus sp.), Taenia tapeworm (Taenia sp.), lancet liver fluke (Dicrocoelium dendriticum), and the protozoa Giardia duodenalis and Entamoeba histolytica. The parasite taxa recovered demonstrate the breadth of species present in this coastal city. We consider the effect of Ottoman Period diet, culture, trade and sanitation upon risk of parasitism in this community living 200 years ago.

Parasite infection rates estimated by examining ancient coprolites can provide insights into parasitism in Joseon society. Using newly discovered Joseon period cases is essential to regularly update the parasite infection rates and reinforce the reliability of our previous estimations. In the present study, we investigated parasite infections in Joseon coprolites newly isolated from the cities of Euijeongbu, Gumi, and Wonju. We then updated the overall parasite infection rates of Joseon period samples (n= 30) as follows: 86.7% (26/30) for Trichuris trichiura, 56.7% (17/30) for Ascaris lumbricoides, 30.0% (9/30) for Clonorchis sinensis, and 30.0% (9/30) for Paragonimus westermani. The parasite infection rates in the Joseon society, estimated through coprolite examination, were very similar to those determined previously despite the addition of new cases to the existing data pool.

In order to investigate the status of intestinal helminthic infections in Cambodia, epidemiological surveys were carried out on a national scale, including 19 provinces. A total of 32,201 fecal samples were collected from schoolchildren and adults between 2006 and 2011 and examined once by the Kato-Katz thick smear technique. The overall egg positive rate of intestinal helminths was 26.2%. The prevalence of hookworms was the highest (9.6%), followed by that of Opisthorchis viverrini/minute intestinal flukes (Ov/MIF) (5.7%), Ascaris lumbricoides (4.6%), and Trichuris trichiura (4.1%). Other types of parasites detected were Enterobius vermicularis (1.1%), Taenia spp. (0.4%), and Hymenolepis spp. (0.2%). The northwestern regions such as the Siem Reap, Oddar Meanchey, and Banteay Meanchey Provinces showed higher prevalences (17.4-22.3%) of hookworms than the other localities. The southwestern areas, including Koh Kong and Preah Sihanouk Provinces showed higher prevalences of A. lumbricoides (17.5-19.2%) and T. trichiura (6.1-21.0%). Meanwhile, the central and southern areas, in particular, Takeo and Kampong Cham Provinces, showed high prevalences of Ov/MIF (23.8-24.0%). The results indicate that a considerably high prevalence of intestinal helminths has been revealed in Cambodia, and thus sustained national parasite control projects are necessary to reduce morbidity due to parasitic infections in Cambodia.

The Nutritional Anaemia due to Iron Deficiency is by for the most common variety of anaemia throughout the world, affecting many women in their reproductive years, infant and children. In Korea, several studies reported that most of the female was iron-deficient and anemic. The present study was undertaken to investigate the nutritional anaemic state of the college girls in kwang-ju city area. Seventy-five college girls in child-bearing age (from 17 to 22 years old) were selected and practiced physical examination, hematological and parasitological tests. The results obtained are summarized as follows; 1) The mean body height $(158.6{\pm}3.4cm)$higher tendency compared to other studies, but the mean body weight $(51.1{\pm}5.6kg)$was lighter. 2) The mean red blood cell number was $441.4{\pm}17.7\;10^4/mm^3$, and most of the subjects were included normal criteria. The average hemoglobin level was $12.5{\pm}0.7gm%$, and 25..7% of the subjects was anaemic. (l2gm% below) The average hematocrit value was $39.1{\pm}2.3%$ and 7.0% was anaemic. (below 37%) The average M C.H.C. value was $32.1{\pm}0.9%$, and 86.0% was anaemic. (32% below) These results showed that the incidence of anaemia was high and the anaemia was characterized by hypochromic in general. 3) The mean value of serum total protein and albumin were $6.6{\pm}0.4gm%$ and $4.2{\pm}0.4gm%$. These values were indicated total protein intake was insufficiency, but albumin value was comparatively high. 4) The infestation rate of helminthes was 25.4%, (Ascaris lumbricoides: 20.3%, Trichuris trichiura: 8.5%) and there was no hookworm infected case.
