is this recently characterized gastrointestinal pathogen responsible for rising rates of inflammatory bowel disease (ibd) and ibd associated autism in europe and the united states in the 1990s?in 2006, a pathogenic variant of the common intestinal organism blastocystis was discovered in patients who were experiencing chronic gastrointestinal symptoms. most species of blastocystis inhabit humans with no symptoms. the discovery of a pathogenic variant of blastocystis is significant, because blastocystis is related to entamoeba, a similar organism with pathogenic variants that kill over 100,000 people each year. recent research has shown that blastocystis infections may be undetectable u ...200717382484
parasitic infections in asymptomatic homosexual men: cost-effective screening.the purpose of this study was to develop a cost-effective strategy for screening for enteric protozoan infections in homosexual men without gastrointestinal symptoms suggesting infection. one hundred and one homosexual men in portland, oregon, each submitted at least one unpurged stool sample; 91% submitted three samples each. of these, 27% had entamoeba histolytica, 61% had nonpathogenic protozoa with or without e. histolytica, 36% had a nonpathogen alone, and 3% had giardia lamblia. protozoan ...19863095515
results of testing for intestinal parasites by state diagnostic laboratories, united states, 1987.we analyzed results of 216,275 stool specimens examined by the state diagnostic laboratories in 1987; parasites were found in 20.1%. percentages were highest for protozoans: giardia lamblia (7.2%), entamoeba coli and endolimax nana (4.2% each), blastocystis hominis (2.6%), entamoeba histolytica (0.9%), and cryptosporidium species (0.2%). identifications of giardia lamblia increased broadly from the 4.0% average found in 1979, with 40 states reporting increases and seven decreases. most states th ...19911779956
