| clinical significance of blastocystis hominis. | a total of 19,252 stool specimens from 12,136 patients were examined by direct microscopy and the ethyl acetate-formalin concentration method during the last 2 years. all liquid specimens and those in which parasite identification was difficult or equivocal were also examined in trichrome-stained preparations. a total of 3,070 intestinal parasites were seen in 2,889 patients. blastocystis hominis was found in fecal material from 647 patients (17.5%). a total of 132 cases (25.6%) were observed to ... | 1989 | 2808664 |
| blastocystis hominis gastroenteritis in a hemophiliac with acquired immune deficiency syndrome. | blastocystis hominis is an enteric protozoan that has occasionally been associated with gastrointestinal illness in man but is not considered an opportunistic pathogen. we describe a 16-year-old hemophiliac with acquired immune deficiency-related complex in whom upper gastrointestinal symptoms in conjunction with high densities of b. hominis in duodenal secretions and stool developed. furazolidone treatment was associated with eradication of the organism and improvement in clinical symptoms. one ... | 1989 | 2732857 |
| [observations on 4 atypical cases of blastocystosis]. | the paper reports on four atypical cases of blastocystosis with prevalence of digestive and cutaneous disorders and of the allergic and general phenomena. the diagnosis could be established only after revealing blastocystis hominis in the fecal parasitologic examination. the disappearance, in all the four cases, of varied clinical, delayed signs after treatment with metronidazol and stamycine (in two or even four repeated treatment schedules at 10 days' interval) is the proof that bl. hominis mi ... | 1989 | 2617001 |
| intestinal parasites in children with diarrhea in el salvador. | in a study of parasitological prevalence in el salvador, stool specimens of 210 children with diarrhea were examined for intestinal parasites. in 104 cases (49%), intestinal helminths and protozoa were found. 53.4% of the specimens showed single infestation, 31.7% showed double. 3% triple and 1% quadruple infestation. of the helminths, 31% were trichuris trichiura, 18% ascaris lumbricoides and 5% hymenolepis nana. of the pathogenic protozoa, 7% were identified as giardia intestinalis, 6% entamoe ... | 1988 | 3262555 |

| freeze-fracture study of blastocystis hominis. | the ultrastructure of blastocystis hominis was investigated by the freeze-fracture method. freeze-fracture replicas of the membranes of b. hominis and its organelles were studied with special regard to the density and distribution of the intramembranous particles (imp's). on all membrane replicas, the concentration of imp's on the protoplasmic face (p face) invariably was greater than on the exoplasmic face (e face). on the p face, imp's were heterogeneously distributed in dense aggregates, alte ... | 1988 | 3199336 |
| [enteritis caused by blastocystis hominis]. | 1988 | 3236933 | |
| biochemical and ultrastructural study of blastocystis hominis. | this study was prompted by the paradox of strong presence of mitochondria in an anaerobic protozoan, recently reclassified from the yeasts. stemming from publication in 1911 to 1912, blastocystis hominis has been generally accepted as a harmless intestinal yeast of humans, with short standardized textbook (parasitology) descriptions, even to the present day. reports since 1967 have changed the classification of b. hominis from yeast to protozoan (sarcodina), and this has been followed by interes ... | 1988 | 2838509 |
| blastocystis hominis: an organism in search of a disease. | blastocystis hominis is a protozoan organism frequently found in the human intestinal tract. eleven consecutive patients with symptoms of enteritis and having b. hominis as the sole enteropathogen were studied in an attempt to define the association of blastocystosis with clinical disease. b. hominis could not be implicated as the etiologic agent of enteritis in any of these patients. all eleven had alternative (and usually noninfectious) explanations for their intestinal symptoms. there was no ... | 1988 | 3055191 |

| [blastocystis hominis--intestinal parasite or commensal?]. | blastocystis hominis has long been classified among blastomycetes. it was considered to be an apathogenous fungal organism which was very frequently detected in routine stool examinations. following the first studies with an electronic microscope in 1967, zierdt et al. (34) classified blastocystis hominis among the protozoa. since then, there have been increasingly frequent reports that blastocystis hominis can be an important cause of intestinal diseases especially diarrhea. for a definite taxo ... | 1988 | 3059694 |
| parasitic diarrhea. | this article reviews the biology, epidemiology, and clinical management of amebiasis, giardiasis, and cryptosporidiosis as well as the less common intestinal protozoa, dientamoeba fragilis, isospora belli, balantidium coli, and blastocystis hominis. | 1988 | 3074123 |
| enzyme immunoassay for detection of giardia lamblia cyst antigens in formalin-fixed and unfixed human stool. | an antigen-capture enzyme-linked immunosorbent assay employing rabbit and mouse antisera to giardia lamblia cyst antigens was developed for the diagnosis of giardia infection through detection of g. lamblia-specific stool antigens in cell-free aqueous eluates of human stool. this is the first report of the use of anti-cyst antibodies in an enzyme immunoassay for g. lamblia. the assay gave a positive result with 54 of 59 stools from patients with symptomatic, clinically diagnosed giardiasis, givi ... | 1988 | 3183015 |
| a survey of gastrointestinal parasites in ogun state, southwest nigeria. | to study the epidemiology of intestinal parasites in ogun state, nigeria, 479 stool specimens were examined at a hospital in abeokuta during the rainy season in june 1986. intestinal helminths and/or protozoa were present in 297 samples (62%). 41.1% of the specimens showed a single infection, 34% showed double, 20% triple and 5% quadruple infection. the most commonly found worm was ascaris lumbricoides (in 40% of specimens), followed by trichuris trichiura (23.2%), hookworms (19.2%), strongyloid ... | 1988 | 3178337 |
| etiology of diarrhea among travelers and foreign residents in nepal. | a bacterial pathogen was isolated from 47% of 328 expatriate patients with diarrhea seen at two medical clinics in nepal in 1986. enterotoxigenic escherichia coli (24%), shigella (14%), and campylobacter species (9%) were isolated most frequently. enteroinvasive and adherence factor-positive e coli were isolated from 2% and 1% of patients, respectively. giardia lamblia was detected in 12% of patients, rotavirus in 8%, and cryptosporidium and entamoeba histolytica each in 5%. blastocystis hominis ... | 1988 | 3404637 |
| presumptive evidence for blastocystis hominis as a cause of colitis. | a patient with persistent diarrhea was found to have biopsy-proved colitis with large numbers of the protozoan blastocystis hominis present in stool. extensive evaluation failed to reveal any other potential etiologic agent of acute colitis. following treatment with a course of metronidazole, the patient became asymptomatic, b hominis was no longer present in stool, and results of a repeated biopsy were normal. these observations are consistent with the role of b hominis as a gastrointestinal pa ... | 1988 | 3365077 |

| blastocystis hominis, a long-misunderstood intestinal parasite. | for over 50 years, blastocystis hominis has been held to be a harmless intestinal yeast-probably frequent in stool samples from man and other primates, but usually ignored except as a possible source of confusion with entamoeba histolytica. more recently, its status as a protozoan parasite has been accepted, and it is now increasingly recognized as an agent of intestinal disease - usually self-limiting but occasionally fatal in monkeys. here, charles zierdt reviews the status o f this intriguing ... | 1988 | 15462991 |

| epidemiology and clinical features associated with blastocystis hominis infection. | a retrospective chart review was performed on 100 patients infected with blastocystis hominis (bh) and 50 randomly selected age and sex matched controls to examine the clinical and epidemiologic features associated with this organism. the finding of greater than 5 bh per oil immersion field (1,000 x) was significantly associated with acute presentation of symptoms but was not predictive of the presence of gastrointestinal symptoms. of patients infected with bh, 57.5% had recently travelled to th ... | 1987 | 3449317 |
| diarrhea due to blastocystis hominis: an old organism revisited. | we have reported a case of diarrhea caused by blastocystis hominis, an intestinal protozoan parasite of man. the organism is present in small numbers in up to one fifth of stool samples in hospitalized patients, but is associated with diarrhea in only heavily infested patients. typical symptoms include diarrhea, crampy abdominal pain, nausea, vomiting, low-grade fever, gas, malaise, and chills. fecal leukocytes are occasionally seen. the pathophysiologic mechanism of the diarrhea is not clear. n ... | 1987 | 3603119 |
| blastocystis hominis: evidence for human pathogenicity and effectiveness of metronidazole therapy. | 1. clinical symptoms and oral treatment with metronidazole were studied in 103 patients with pure infections by blastocystis hominis. 2. the results showed that excessive flatulence is the chief gastrointestinal symptom associated occasionally with diarrhoea and abdominal cramps. all the patients showed good responses with treatment of metronidazole and 74 patients whose stools were reexamined 1-2 months after the treatment demonstrated no signs of infections. 3. it is concluded that b. hominis ... | 1987 | 3665198 |
| cryptosporidiosis in ogun state, south-west nigeria. | during the period of one month in the rainy season in ogun state in south-west nigeria 479 stool samples (420 of which were diarrhoea stool samples) were examined for cryptosporidiosis. oocysts were detected in 2.3% of all stools, in 2.6% of diarrhoeal stools and in 5.3% out of 150 children with diarrhoea. cryptosporidium was the sole pathogen detected in six of 11 cases. in addition to cryptosporidia also entamoeba histolytica, blastocystis hominis, giardia lamblia, ascaris lumbricoides, and tr ... | 1987 | 3602839 |
| light-microscopical appearance and ultrastructure of blastocystis hominis, an intestinal parasite of man. | a study on blastocystis hominis was undertaken for the purpose of clarifying the morphology of the organism using the following techniques; giemsa, heidenhain iron hematoxylin, and dapi stains, phase-contrast microscopy, and transmission- and scanning-electron microscopy. microscopic examinations of the lumen fluids aspirated at the endoscopical examination revealed the habitation of b. hominis in the lower ileum and cecum of a patient. when examined light-microscopically, organisms from stool m ... | 1987 | 3660977 |

| blastocystis hominis: pathogen or fellow traveler? | blastocystis hominis, an intestinal organism of uncertain taxonomic position, has long been considered nonpathogenic. some recent studies suggest, however, that it may be associated with diarrhea and may respond to treatment with iodoquinol or metronidazole. to investigate this possibility, we identified 148 persons whose stools contained this organism. of this number, 32 had at least 6 stool examinations performed. twenty-seven of the 32 persons were later found to have greater than or equal to ... | 1986 | 3766850 |
| association of blastocystis hominis with signs and symptoms of human disease. | purged stools from 389 patients were evaluated microscopically for the presence of blastocystis hominis. a total of five or more b. hominis cells per 40x field were observed in 43 patients (11%), and b. hominis was the only intestinal parasite present in 23 (6%) of these patients. of the 23 patients, 19 had symptoms which included abdominal discomfort (15 patients), anorexia (10 patients), diarrhea (9 patients), and flatus (9 patients). the remaining four patients were asymptomatic. the proporti ... | 1986 | 3771743 |
| parasitological observations of chronic diarrhoea in suspected aids adult patients in kinshasa (zaire). | the parasitological profile of chronic diarrhoea in 46 zairian adults suspected of aids demonstrated that the frequency of protozoa was five times higher than that of helminths; 86% of the protozoa were sporozoa: isospora belli was the most frequent (19%), followed by cryptosporidium isolated for the first time in zaire (8%) and blastocystis hominis (2%). 37 of the 46 patients were immunodeficient. | 1986 | 3787692 |
| cytochrome-free mitochondria of an anaerobic protozoan--blastocystis hominis. | isolated mitochondria of the anaerobic protozoan blastocystis hominis were subjected to spectral analysis, color, catalase, and peroxidase tests and found to be completely negative for cytochrome enzymes, catalase, and peroxide. based on the absence of cytochrome enzymes, the possible evolution of b. hominis mitochondria from anaerobic bacteria is postulated. | 1986 | 3959009 |
