| purification and properties of nadp-linked, alcohol dehydrogenase from entamoeba histolytica. | an nadp-linked, alcohol dehydrogenase from entamoeba histolytica was purified to apparent homogeneity by blue sepharose affinity chromatography. molecular weights of 130,000 and 30,000 were estimated by gel filtration and by sodium dodecyl sulfate polyacrylamide gel electrophoresis, respectively, suggesting that the enzyme is a tetramer. the enzyme exhibited more than 20-fold selectivity for nadp(h) over nad(h). although the purified enzyme acts on both primary and secondary alcohols, higher act ... | 1982 | 6284905 |
| mouse ige response to an allergen from entamoeba histolytica. | attempts were made to demonstrate the presence of allergenic components in an extract of axenically cultured entamoeba histolytica (hk 9). various strains of mice were immunized i.p. with a low dose of the extract mixed with al(oh)3 and boosted with the same mixture 4 wk later. a high titer of ige antibody response was demonstrated in balb/c, dba/2 (h-2d), cba (h-2k), and swm strains but not in c3h/he (h-2k) strain. the extract was fractionated by gel filtration with sephadex g-200 and then by d ... | 1982 | 6284906 |
| the epidemiology of entamoeba histolytica in a rural and an urban area of mexico. a pilot survey ii. | stocks of intestinal amoebae grown in monoxenic culture, were compared against each other and against those previously reported from mexico city. these were isolated from subjects in san cristobal de las casas, chiapas (rural area) and hospital patients in merida, yucatan (urban area). electrophoretic patterns of the four enzymes: glucose phosphate isomerase (gpi), phosphoglucomutase (pgm), l-malate: nadp+ oxido-reductase (oxalacetate-decarboxylating) (me) and hexokinase (hk) demonstrated the pr ... | 1982 | 6285556 |
| comparison of indirect fluorescent-antibody amoebic serology with counterimmunoelectrophoresis and indirect hemagglutination amoebic serologies. | patients ranged from those with no prior diagnosis of or suspected exposure to entamoeba histolytica to those with proven amoebic liver abscesses (extraintestinal disease). a comparison of serologies from patients with proven and suspected amoebiasis or possible past exposure revealed good correlation between the indirect fluorescent antibody (ifa) procedure and the other methods used, counterimmunoelectrophoresis and indirect hemagglutination. titers from patients with proven extraintestinal am ... | 1982 | 6279694 |

| the collagenase of entamoeba histolytica. | the present work was designed to investigate the capacity of trophozoites of entamoeba histolytica to adhere to and digest human collagen types i and iii in vitro. the time-course of binding of ameba to both human collagen types i and iii was similar. however, the kinetics of detachment were different for each collagen type. trophozoites of e. histolytica cultured on heat-reconstituted type i collagen gels produced a well-defined area of lysis. quantitative studies using 14c-labeled collagen rev ... | 1982 | 6274995 |
| a study of intestinal protozoa including non-pathogenic entamoeba histolytica from patients in a group of mental hospitals. | twenty-five per cent of 174 patients residing in three mental hospitals were found to be infected with protozoa. seven per cent of the patients were infected with entameba histolytica. isoenzyme characterization of the e. histolytica grown in culture showed that there were no pathogenic zymodemes of this organism in any of the specimens tested.

| an ion-channel forming protein produced by entamoeba histolytica. | we have identified a remarkable ion-channel forming material in virulent strains of entamoeba histolytica that may be responsible for many of the symptoms associated with amoebic dysentery. a polypeptide that we refer to as amoebapore is shed into the growth media and is also found within the amoeba in a high speed sedimentable fraction. amoebapore has the distinctive property of spontaneously incorporating into lipid bilayers, liposomes, and cells, leading to progressive and irreversible change ... | 1982 | 6329705 |
| parasitic bowel disease: three pathogens important in primary care. | a high index of suspicion and careful application of diagnostic methods are essential for accurate diagnosis of parasitic bowel diseases. the varied clinical spectrum of giardiasis, amebiasis, and strongyloidiasis emphasizes the need to consider these pathogens when patients present with gastrointestinal complaints. giardiasis should be suspected in patients, especially returned travelers, with unexplained increase in stool frequency, particularly with bloating, flatulence, or vague systemic sym ... | 1982 | 6280160 |
| characterization of a membrane pore-forming protein from entamoeba histolytica. | we describe the partial purification and characterization of a pore-forming material (pem) from entamoeba histolytica. the formation of ion channels by pfm was examined in three systems. (a) pfm depolarizes j774 macrophages and mouse spleen lymphocytes as measured by [3h]tpp+ uptake. (b) pfm induces rapid monovalent cation flux across the membrane of phosphatidylcholine-cholesterol vesicles. (c) pfm confers a voltage-dependent conductance to artificial planar bilayers, which is resolved as a sum ... | 1982 | 6294211 |
| the colitides. | diverse signs may be seen on barium enema in the various forms of colitis. barium enema is only reasonably specific in the diagnosis of crohn's disease and ulcerative colitis once the other possible diseases have been excluded from consideration by biopsy, microscopy, culture, or therapeutic trial. in particular, campylobacter colitis has proved to be such a common entity that many patients originally thought to have had one attack of ulcerative colitis, ischemic colitis, or crohn's colitis may ... | 1982 | 6294727 |
| isolated entamoeba histolytica actin does not inhibit dnase-i activity. | 1982 | 6280688 | |
| in vitro amoebicidal activity of immune cells. | the amoebicidal activity of peripheral blood lymphocytes and spleen and peritoneal cells from hamsters vaccinated against or protected from hepatic amoebiasis and from those with hepatic amoebiasis was investigated. peripheral blood lymphocytes and peritoneal and spleen cells from vaccinated or protected animals can kill trophozoites of entamoeba histolytica in vitro. in contrast, spleen cells from infected hamsters showed no significant cytotoxic effect on the parasite. these data suggest that ... | 1982 | 6281189 |
| attachment and ingestion of bacteria by trophozoites of entamoeba histolytica. | entamoeba histolytica trophozoites were found to be very selective in their interactions with bacteria. two principal mechanisms were shown to be responsible for these interactions. certain bacteria, such as a number of escherichia coli and serratia marcescens strains which are known to contain mannose-binding components on their cell surface, bound to mannose receptors on the amoeba membrane. this attachment was markedly inhibited by alpha-methylmannoside (0.5%), especially when the incubations ... | 1982 | 6281192 |

| immunology of entamoeba histolytica in human and animal hosts. | although entamoeba histolytica induces humoral and cellular immune responses in both human and animal hosts, there is no indication of postinfection immunity in humans; in contrast, several other mammals are protected by prior infection or immunization. the exacerbation of the disease by immunosuppression suggests a protective function of still-unknown defense mechanisms. specific local and circulating antibodies are produced regularly during invasive amebiasis. although serum antibodies, togeth ... | 1982 | 6296962 |
| a review of the parasite cellular mechanisms involved in the pathogenesis of amebiasis. | amebiasis, a significant cause of morbidity and mortality on a global scale, is caused by invasion of the colonic mucosa by the cytolytic protozoan parasite entamoeba histolytica. a review of the investigations into the mechanisms by which the parasite causes invasive disease is presented, including the relevant history, epidemiology, and pathology of amebiasis, the biology of the parasite, in vivo and in vitro studies of the pathogenesis of disease, the host immune responses, and possibilities ... | 1982 | 6296963 |
| amebiasis: host-pathogen biology. | invasive amebiasis caused by entamoeba histolytica, and particularly amebic liver abscess, is a major public health problem in mexico and some other countries because of the high incidence and mortality of this disease. this paper first discusses the pathogenic effect of e. histolytica and the defensive response of the host and then reports studies concerning the experimental induction of protective immunity to amebic infection. the pathogenic effect of e. histolytica is probably initiated by a ... | 1982 | 6296964 |

| [amebiasis]. | infections with entamoeba histolytica do not necessarily cause disease in those infected. the parasite may act as commensal (cysts living in the bowel) or it may cause a broad spectrum of clinical illness. some of the factors causing overt disease are poorly understood. an acute amebic dysentery is accompanied by bloody stools, abdominal pain and indigestion. the most important extraintestinal complication of an amebic infection is a liver abscess causing severe pain, fever, nausea and vomiting. ... | 1982 | 6286439 |
| adhesion of entamoeba histolytica trophozoites to human erythrocytes. | to understand the mechanism of entamoeba histolytica adhesion, we characterized the binding of trophozoites to human erythrocytes (rbc) in suspension by measuring the kinetics of amoeba-rbc complex formation. adhesion was very efficient, since most of the amoebae were complexed with rbc after only 5 min at 37 degrees c in mixtures containing 10(4) amoebae and 10(6) rbc per ml; the adhesion rate depended on amoeba and rbc concentrations, but not on the a, b, and o human blood groups, and was maxi ... | 1982 | 6286491 |
| effect of ion channel inhibitors on the cytopathogenicity of entamoeba histolytica. | entamoeba histolytica (axenic strain hm1-imss), a cytolytic enteric pathogen, kills target chinese hamster ovary cells in two discrete steps: (1) carbohydrate-specific adherence of amoebae to target cells, followed by (2) cytolysis of adherent target cells. both steps require intact amoebic microfilament function. the effects of the fast na+ channel blocker tetrodotoxin and the slow na+-ca++ channel blockers verapamil (10(-5) m) and bepridil (10(-5) m) on amoebic killing were evaluated. verapami ... | 1982 | 6286794 |
| indirect hemagglutination antibody titers for entamoeba histolytica in dried filter paper blood and sera. | serum and elutates from dried filter paper bloods from 404 patients with and without amebic liver abscess (ala) were tested for entamoeba histolytica antibodies by the indirect hemagglutination test. eighty-nine percent of the sera from patients with ala were positive (titers greater than or equal to 1 : 128) and 94% of those without ala negative. fifty-five percent of the filter paper bloods from ala patients were positive. overall agreement was 80% for positives and negatives and the correlati ... | 1982 | 6287648 |
| preliminary observations using a multi-layer elisa method for the detection of entamoeba histolytica trophozoite antigens in stool samples. | a method for detecting entamoeba histolytica trophozoite antigens in aqueous solution is described. this involves coating plastic microtitre plates with a 'catching antibody', specific rabbit anti-e. histolytica antibody (srae). after adding the test material the presence of antigen is determined using two additional heterologous antibody layers, one of 'developing antibody', in this case human anti-e. histolytica immunoglobulin (hae), which is followed by a final layer of peroxidase conjugated ... | 1982 | 6287685 |
| a zymodeme study of entamoeba histolytica in a group of south african schoolchildren. | using a biphasic culture medium, stocks of intestinal amoebae were isolated from a group of children attending school in durban, south africa. these were compared with stocks collected in other areas of the world already characterized using the electrophoretic patterns of four enzymes: glucose phosphate isomerase (gpi), phosphoglucomutase (pgm) l-malate: nadp+ oxido-reductase (oxalacetate-decarboxylating) (me) and hexokinase (hk). 33% of 94 samples grew entamoeba histolytica, only one of which g ... | 1982 | 6287686 |

| macrophage requirement for host defence against experimental hepatic amoebiasis in the hamster. | the role of macrophages in hepatic amoebiasis in hamsters has been investigated by means of their treatment with bacille calmette-guérin (bcg) for activation, and with silica for elimination of these cells. silica-treated animals inoculated intrahepatically with 1 x 10(5) trophozoites of entamoeba histolytica developed amoebic abscesses in the liver and more metastases to other organs than control animals, and this effect was silica-dose-dependent. in contrast, bcg-treated animals developed sign ... | 1982 | 6289225 |
| amebiasis: nutritional implications. | studies on the role of nutrition in amebiasis in humans and experimental animals are meager. some reports suggest that malnutrition of the host increases the incidence of infection and potentiates the severity of the disease. others suggest that malnutrition protects the host against invasion. a few reports indicate that dietary regimens can alleviate symptoms and even eradicate the parasite. others doubt a correlation between diet and rate of infection or disease manifestations. the problem is ... | 1982 | 6289405 |

| a solid-phase sandwich radioimmunoassay for entamoeba histolytica proteins and the detection of circulating antigens in amoebiasis. | a sensitive and specific immunochemical assay for entamoeba histolytica antigens would be a valuable tool for clinical diagnosis, to study the sequelae of amoebiasis, and to screen for the expression of amoebic proteins in recombinant bacterial clones. the major impediment toward developing such an assay is the cross-reactivity of anti-e. histolytica antisera with a wide range of mammalian serum proteins. a rabbit anti-e. histolytica antiserum was repeatedly passed over three bovine serum protei ... | 1982 | 6290308 |
