contribution to the problem of the so-called nonpathogenic amoebae in the intestine of man.	among 10,418 patients of a prague hospital, a plain infection with intestinal parasitic protozoans was identified in 1,319 persons (12.7%). of these, 3.5% were infested with giardia intestinalis, 0.3% with entamoeba histolytica forma minuta, 5.7% with endolimax nana. we evaluated the frequency of findings of protozoans in various clinical diagnoses. a statistically significant increase in frequency was recorded for e. nana in diagnoses of eosinophilia, giardiasis, amoebiasis and helminthiasis. ...	1978	217807

activation of the alternative pathway of complement by entamoeba histolytica.	a cytopathogenic effect was observed when entamoeba histolytica was exposed to human sera from individuals with no clinical history or laboratory evidence of amoebiasis. absorption studies showed that the effect was not due to natural antibodies. studies performed using ethylenediamine tetracetic acid (edta), cobra venom factor (cof) and heat-inactivation at 56 degrees c, indicated that the cytopathogenic effect was complement dependent. furthermore, by using ethylene glycol tetracetic acid (egt ...	1978	219975

latex agglutination test for amoebiasis in pakistani patients with chronic 'obscure' liver enlargements.	the latex agglutination test for amoebiasis was done in 50 pakistani patients in whom a clinical diagnosis of chronic non-supparative amoebic hepatitis was made on the basis of liver enlargement associated with chronic recurrent abdominal disturbance. the serological test was negative in 32 (64%) and positive in 18 (36%). examination of stool specimens showed a higher frequency of e. histolytica in serology positive patients. the liver biopsy findings were variable and included normal histology ...	1978	204801
dynamics of the interaction between entamoeba histolytica and components of the immune response. i. capping and endocytosis; influence of inhibiting and accelerating factors; variation of the expression of surface antigens.	the possible implications of cell membrane dynamics in the host--parasite relationship has been studied. entamoeba histolytica rapidly redistributed and internalized antibodies and con a bound to its surface. the process was dependent on temperature, cell metabolism and changes of ph in the environment. phagocytizing amoebae displayed a higher rate of membrane perturbations, which were similarly affected by temperature, cell metabolism and ph variations. cytochalasin b partially inhibited the re ...	1978	76334
pyruvate-to-ethanol pathway in entamoeba histolytica.	the pyruvate-to-ethanol pathway in entamoeba histolytica is unusual when compared with most investigated organisms. pyruvate decarboxylase (ec 4.1.1.1), a key enzyme for ethanol production, is not found. pyruvate is converted into acetyl-coa and co2 by the enzyme pyruvate synthase (ec 1.2.7.1), which has been demonstrated previously in this parasitic amoeba. acetyl-coa is reduced to acetaldehyde and coa by the enzyme aldehyde dehydrogenase (acylating) (ec 1.2.1.10) at an enzyme activity of 9 uni ...	1978	25658
membrane bound pyrophosphatases in entamoeba histolytica.	entamoeba histolytica homogenates are capable of hydrolyzing a range of inorganic and organic pyrophosphates. two separate activities are present: an inorganic pyrophosphatase hydrolyzing inorganic pyrophosphate and linear tripolyphosphate, and a nucleoside diphosphatase hydrolyzing thiamine pyrophosphate and nucleoside diphosphates (adp, gdp and udp). the inorganic pyrophosphatase has an acid ph optimum, a relatively high km (congurent to 1 micrometer) and is markedly heat stable and lacks a me ...	1978	29580

[the influence of cytochalasin b, colchicine, and vinblastine on the attachment of entamoeba histolytica to glass surfaces (author's transl)].	the attachment of e. histolytica trophozoites from monoxenic tps-medium to glass surfaces was studied at different temperatures and ph values and in the presence of cytochalasin b, colchicine, and vinblastine. at ph 7.0 and at 36 degrees c optimal adhesion rates of the amebae were observed in the range from 80% to 95%. marked inhibition of adhesion was noted at higher concentrations of cytochalasin b. the adhesion rate was reduced to 50% by 50 micrograms/ml cb. higher dosages successively preven ...	1979	44594

riboflavin requirement for the cultivation of axenic entamoeba histolytica.	riboflavin was found to be essential for the cultivation of axenic entamoeba histolytica. this is the first demonstration of a flavin requirement by the organism. panmede, the principal source of flavins in the axenic medium, was treated with activated carbon to remove flavins. medium made with this flavin-deficient panmede, and supplemented with ribonucleic acid failed to support the multiplication of amebae in serial subculture, but did so when riboflavin was added. the concentration of ribofl ...	1979	222153
the serologic response of hamsters to experimental liver inoculations with entamoeba histolytica as measured by indirect hemagglutination test and enzyme linked immunosorbent assay.	results of testing 298 sera from hamsters inoculated in the liver with entamoeba histolytica and from 25 uninoculated controls by indirect hemagglutination (iha) and enzyme linked immunosorbent assay (elisa) showed that measurable amounts of antibody appeared as early as 5 days after inoculation, generally increased to a high level within 20 days, and persisted for the duration of the experiments (58 days). there was fair correlation between size of liver lesion and titers. strain differences in ...	1979	222154

surface redistribution and release of antibody-induced caps in entamoebae.	polyspecific antibodies bound to entamoeba induced surface redistribution of membrane components toward the uroid region. capping of surface antigens was obtained with a single layer of antibodies in e. histolytica and e. invadens. this surface segregation progressed to a large accumulation of folded plasma membrane that extruded as a defined vesicular cap. a spontaneous release of the cap at the end of the capping process took place. these released caps contained most of the antibodies that ori ...	1980	6243156
immunoglobulin e and a levels in atopic and anaphylactic children.	seventy-six children between 18 months and 12 years of age were included in this study. sixty-one were atopic and 15 had anaphylaxis due to bee stings or drugs. immunoglobulins: a, g. m and e were determined and evaluated with respect to age and diagnosis. iga levels were lower in atopic children between six and ten years than in normals. ige levels were high in both atopic and anaphylactic patients but higher in the atopic than in the anaphylactic group. the results are discussed, focusing on t ...	1980	6243451
amebic abscess of the brain.	brain abscesses caused by entamoeba histolytica were treated in two residents of new jersey, neither of whom had traveled beyond the eastern united states. the diagnosis in case 1 was confirmed by the presence of ameba in both brain and pituitary abscesses. an elevated indirect hemagglutination (iha) titer of 1:4096 and response to specific treatment with metronidazole and chloroquin were the criteria for diagnosis in case 2. the computerized tomographic appearance of an amebic abscess is that o ...	1980	6245387

[use of an enzymatic immune method (elisa) for the serodiagnosis of amebiasis].	the enzyme linked immunosorbent assay (elisa) was compared with the indirect immunofluorescence antibody test (ifat) and with the counter-immunoelectrophoresis (cie) in the serology of amebiasis. in cases of liver abscesses, the elisa was as sensitive as cie, but slightly more sensitive than ifat. in cases where the patient asymptomatically passed cysts of e. histolytica, none of the three tests was positive. as a routine laboratory screening test, the elisa proved to be the most convenient of t ...	1980	6245444
