| fine structural changes at entamoeba histolytica rabbit kidney cell (rk 13) interface. | when bacteria-free trophozoites of entamoeba histolytica were added to a monolayer of rabbit kidney cells, cellular injury occurred at the sites of contact. changes appeared within the cell cytoplasm before there was any generalized cell membrane damage. at some points of contact there was apparent fusion of amoebic and cell cytoplasm. electron-dense bodies, here interpreted as liposomes, were present in the amoebic cytoplasm and beneath the surface membrane. no surface lysosomes were seen. vari ... | 1975 | 168818 |
| [coprologic survey in bilharzia infected children of the adzope region (ivory coast)]. | during a stool examination survey on 174 bilharzia attained children living in a rural area of ivory coast, 93% were found to have intestinal parasites mainly entamoeba coli, necator americanus and ascaris lumbricoides. the prevalence of the cysts of entamoeba histolytica (4,7%) is lower than the one found in france (7%). concerning the other intestinal parasites, their respective occurrence have been compared with those noted in other regions of ivory coast and of africa. | 1975 | 170007 |
| [hepatic amebiasis in an infant]. | case report of a 8 month-old north-african infant with liver amebiasis. this disease is not rare in young children and may be observed in all endemic zones of amebiasis. the clinical characteristics, special for the age, and the biological features are reviewed. the diagnosis relies on immunological tests. treatment is essentially medical, metronidazole often being effective. | 1975 | 170879 |
| pathogenicity of entamoeba histolytica. | the pathogenicity of entamoeba histolytica is discussed from an immunologic point of view. the evidence that there is some "trigger" mechanism which converts a commensal dwelling organism into a tissue invasive pathogen is rejected as inadequate. the number of liver abscess cases in comparison with the number of intestinal amebic infections in a population is so low that this in itself suggests that tissue invasion is a rare event in the life history of the ameba. a review is made of the experim ... | 1975 | 171223 |
| isolation and characterization of a pyrophosphate-dependent phosphofructokinase from propionibacterium shermanii. | a pyrophosphate-dependent phosphofructokinase (pyrophosphate; d-fructose-6-phosphate-1-phosphotransferase) has been purified and characterized from extracts of propionibacterium shermanii. the enzyme catalyzes the transfer of phosphate from pyrophosphate to fructose 6-phosphate to yield fructose-1,6-p2 and phosphate. this unique enzymatic activity was observed initially in entamoeba histolytica (reeves, r.e., south, d.j., blytt, h.g., and warren, l. g. (1974) j. biol. chem. 249, 7734-7741). this ... | 1975 | 171261 |
