  • A small scale survey was performed to know the infection status of intestinal parasite in children of the residential institutions and street communities in Metro Manila, Philippines. A total of 284 stool samples from 11 institutions and 3 street communities was examined by the formalin-ether concentration method. The scotch tape anal swab was adapted to 121 children to investigate the infection status of Enterovius vermicularis. It was found out that 62.0% of the children examined were positive for one or more intestinal parasites. Multiple infections were observed in 34.2% of the children. Among 172 children who gave detail information, the prevalence for Ascaris lumbricoides, Trichuris trichiura, and hookworm was 36.0%, 44.8%, and 7.0% respectively. Of the children examined, 47.7% were found to be harboring parasitic protozoans such as Entamoeba histolytica, Giardia lamblia, and Blastocystis hominis. The most prevalent of these protozoans was B. hominis with an infection rate of 40.7%. The prevalence of these infections among children living in institutions was relatively high. More efforts should be made to implement anthelminthic programs including bi-annual follow-up treatments.

  • This survey of endoparasite infections among stray cats in Korea has been carried out during November 1995 to October 1997. A total of 215 stray cats were collected from SeoulㆍGyeonggi (54), Gangwon (38), Chungchong (34), Jeonla (38), and Gyeoungsang (51) areas. The positive rate of endoparasites was 184 (85.6%) cats among 215. Of isolated parasites, nematodes were the most often detected parasites especially Toxocara cati (102 cats), Ancylostoma tubaeformae (9 cats). The next most often detected parasites were cestodes (60/215; 27.9%) sepecially Spirometra erinaecei (34 cats), Taenia taeniaformis (26 cats). Opisthorchis tenuicollis was found in bile duct (9 cats) and Isospora spp. were identified in 41 cats (19.1 %). In mixed parasite infection, the rate of infections of nematodes, trematodes and protozoas was 3.3%, nematodes and cestodes with 8.8%, nematodes and protozoa with 4.2%, cestodes and protozoa with 1.9%. In parasitic infection by a considering age category, age from 2 to 4 years had the highest infection (92.3%), 1-2 years were 87.6%, over 4 years was 80.0%. 79.6 percents of the stray cats in SeoulㆍKyounggi areas were ranked the 1st in parasite infection. The next was Kyoungsang 76.5%, Kangwon 65.8%, Cholla 63.2% and Chungchong 61.8% in order. Considering age categories from birth to greater than 4 years, parasite infections were most prevalent in cats 2 to 4 years old; other ages seemed to have no effect on prevalence of parasitism. Also sex seemed to have no effect on prevalence of parasitism. In endoparasite infection, nematode and cestode infections were most frequently found, trematode infections were low, coccidiosis was showed very often.

  • Fecal samples were taken from 402 cows in Posung, Chonnam where was designated as a place for Korean native cattle breeding. Prevalence of intestinal parasitism were determined by the fecal examinations using the floatation and sedimintation procedures. 62.9% of the cows were found as positive cases with excretion of the eggs of Fasciola hepatica in the fecal specimens. Of those infected with F.hepatica 97 cows free of the pathogenic intestinal parasites were chosen for albendazole treatment. Albendazole tablets(10mg / kg) were administered to the cows twice at the interval of 4 weeks. Blood samples were collected via jugular vein prior to the first treatment. four weeks after the first treatment and four weeks after the second treatment respectively. At the same time fecal samples were collected for parasitological examination by sedimintation methods. The mean treatment count was 44 fluke egg per gram of feces, which compared with 27 EPG and 17 EPG four weeks after the first and second treatment, respectively. Most of the hematological values fluctuated within the normal range during the experiment. Eosinophil counts were high initially, decreased after the first treatment and there after remained steady.

  • A 55-year old Korean man, living in Mokpo-city, Jeollanam-do, Republic of Korea, visited a local clinic complaining of right upper quadrant pain and indigestion. At colonoscopy, he was diagnosed as having a carcinoma of the ascending colon, and thus, a palliative right hemicolectomy was performed. Subsequently, an adult fluke of Gymnophalloides seoi was incidentally found in a surgical pathology specimen of the lymph node around the colon. The worm was found to have invaded gut lymphoid tissue, with characteristic morphologies of a large oral sucker, a small ventral sucker, and a ventral pit surrounded by strong muscle fibers. This is the first reported case of mucosal tissue invasion by G. seoi in the human intestinal tract.

  • In this study we take a closer look at the diseases that afflicted Japanese police officers who were stationed in a remote mountainous region of Taiwan from 1921 to 1944. Samples were taken from the latrine at the Huabanuo police outpost, and analyzed for the eggs of intestinal parasites, using microscopy and ELISA. The eggs of Eurytrema sp., (possibly E. pancreaticum), whipworm and roundworm were shown to be present. True infection with Eurytrema would indicate that the policemen ate uncooked grasshoppers and crickets infected with the parasite. However, false parasitism might also occur if the policemen ate the uncooked intestines of infected cattle, and the Eurytrema eggs passed through the human intestines. These findings provide an insight into the diet and health of the Japanese colonists in Taiwan nearly a century ago.

  • 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.

  • According to the dietary surveys and national food balance sheets, the dietary state of person living in Korea is ingesting a high level of grain and vegetable diet and very low animal sources. The daily calory intake is about 2,300-2,600 Cal. per head in which a total protein intake is 69-86 gm respectively. These data indicate no shortage of calory and total protein intake. However, the intake of animal protein is only 4-11 gm and the fat is 8-18 gm, both of which are far below the requirment. The low fat intake brings about a low level of fat soluble vitamins, and that V-A intake is as short as the half amount of the allowance. Riboflavine is also about a half of dietary requirment. Both thiamin and ascorbic acid intake are sufficient. The calcium intake is 0.26-0.5 gm per day which is inadequate. In fact, biochemical findings through field survey show; serum protein 6.7 gm, hemoglobin 13.1 gm and hematocrite 41.5% all of which are lower than the Kwon's report. The serum V-A and uunrinary riboflavin value are also lower than the Williams'es report. Clinically, inflamation of the eyes, cheilosis, pathological signs of tangue, xerosis of the hand and arm, or the like are frequently seen. On the other hand, there is no suitable diet available for the weaning infant and delayed weaning is a common practice. A school lunch program is still in an early stage of development. Another example can be cited that the Korean infant grows faster than the Japanese until one year of age, and no difference is noted between the Korean and the American infants up to six monthes of age, thereafter the former lags in the growth rate. This might be mainly due to the nutritional reasons as mentioned above, and in part due to the high inidence of intestinal parasitism and others.

  • This study was carried out to investigate the prevalence of fascioliasis of slaughtered and farmed cattle in Gwangju area from February to November in 2007. A total of 1,000 cattle fecal samples were collected from slaughter houses (n=805) and farms (n=185). Twelve (1.2%) were found as positive cases with excretion of the egg of Fasciola spp in the fecal specimens, and 128 (12.8%) were positive in intestinal parasitism using the flotation and sedimentation procedures. The infection rate of fluke larvae from the slaughtered cattle at abattoirs in Gwangju was 0.75% (6 out of 805 heads). In histopathology, there were several liver lesions such as inflammation with infiltration of eosinophil, polymorphonuclear cells, mononuclear cells and multinucleated giant cells, proliferation of connective tissue, calcification and abscess formation.
