| pubmed-article:19287363 | pubmed:abstractText | A survey on intestinal parasitic infections and some risk factors of infection (social, economic and behavioral) was conducted in suburban area at Simum subdistrict, Mueang district, Nakhon Ratchasima Province during the period of April 3rd to April 11th, 2007. A total of 214 stool samples, from 85 males and 129 females were examined using simple direct smear, Kato's thick smear and modified Harada-Mori Filter Paper Strip culture technique. The results showed that the prevalence rate of protozoa infections by simple direct smear method was 17.3% (37 infected samples) in 11 males and 26 females and were from all age groups. Mixed infections (56.8%), showed higher results than single infection. The highest number of intestinal protozoan infections was Entamoeba histolytica (11.7%), followed by Blastocystis hominis (5.6%). Fifty four percent of protozoan infection was at a moderate to high level. Ninety five percent of infected cases consumed unboiled water. The prevalence rate of helminthic infections was 7% total by Kato's thick smear and Modified Harada-Mori Filter Paper Strip culture technique. Kato's Thick smear Technique showed the highest rate of Strongyloides stercolaris (2.8%), followed by hookworm infection (1.4%) Taenia spp. (0.9%), and Enterobius vermicularis (0.5%), respectively. All infections showed a light intensity, (< 200 epg), using Kato-Katz thick smear. Although Modified Harada-Mori's culture Technique showed higher S. stercolaris (3.3%) and hookworm infection (2.3%) than Kato's thick smear in the area where there is low Soil transmitted helminthes, we recommend using Simple or Kato's thick smear to determine the prevalence of parasitic infection due to these techniques being able to detect various groups of parasites, and being inexpensive and less time consuming. | lld:pubmed |
