indirect fluorescent antibody technique in the serology of toxoplasma gondii.the indirect fluorescent antibody technique has been used to titrate patients' antibody against toxoplasma gondii. rigorous tests of the immunological validity of the method were made. the reactions of the gamma globulin of human immune serum with toxoplasma gondii and fluorescent rabbit anti-human gamma globulin were thus shown to be specific. thereafter the technique could be used with confidence to detect the reaction between doubling dilutions of patient's serum and smears of unfixed toxopla ...196514276154

a survey of toxoplasmosis among mentally retarded children.to determine what role, if any, toxoplasmosis plays in the mental retardation of children, sera from 345 mentally retarded children were tested for the presence of antibodies to toxoplasma gondii. the serological tests employed were the complement-fixation, the sabin-feldman dye test and the immunofluorescence test. the donors were also skin-tested with toxoplasmin.of 345 mentally retarded donors nine gave a positive skin reaction, 15 possessed complement-fixing antibodies, 21 had immunofluoresc ...196514282158

factors enhancing the host-cell penetration of toxoplasma gondii.the penetration into hela cells of toxoplasma gondii was studied with a cell culture technique. the influence on the rate of penetration and the number of penetrating toxoplasma parasites was tested by use of preparations of disintegrated parasites mixed with test parasites. these preparations were found to contain factors enhancing the penetrating rate of the parasites. this effect was demonstrable by use of untreated parasites as well as parasites lacking active motility owing to a previous ex ...19676020423

isolation and preservation of toxoplasma gondii.thirteen isolations of toxoplasma gondii were made from 110 specimens of various human tissues and tissue fluids. twelve of these were from lymph nodes and one from a specimen of cerebrospinal fluid; all isolations were from cases with dye test titres of 1/512 or more. a description of the deep freeze method used to preserve the t. gondii strains isolated is included. it is hoped that attempts at isolation of this organism will be made more frequently in future.19675602564

lysosomes of toxoplasma gondii and their possible relation to the host-cell penetration of toxoplasma parasites.lysosome-like structures of toxoplasma gondii were observed by means of vital staining with acridine orange and by the gomori technique. these structures were found scattered over the cytoplasm but were often located at one end of the parasite. in comparison with parasites of the inoculum used for infecting hela cell cultures, the toxoplasma which had penetrated the hela cells revealed a markedly lower percentage of parasites showing lysosomal staining. after the penetration, the number of paras ...19684176646
toxoplasma gondii and cytomegalovirus: mixed infection by a parasite and a virus.human fibroblasts infected in vitro with cytomegalovirus are relatively resistant to infection by toxoplasma gondii during the first 4 days of virus infection. after 5 days, however, the cytomegalovirus-infected cells become susceptible to the parasites. the toxoplasmas replicate in paracentral rosettes surrounded by host cell mitochondria. this growth configuration differs from that seen in human fibroblasts infected in vitro with toxoplasma only but resembles the pattern seen in doubly infecte ...19684296707
interferon: protection of cells infected with an intracellular protozoan (toxoplasma gondii).chick and mouse cell monolayers treated with interferon were significantly protected from destruction by toxoplasma. the results suggest that fewer numbers of organisms were released from interferon-treated cells. interferons were uniformly more active in a viral assay than in a toxoplasma assay, and they had the same properties in both assays. the data suggest that interferon activity may be directed against organisms phylogenetically higher than viruses.19684298747
immunity and intracellular infection: resistance to bacteria in mice infected with a protozoan.mice infected with the intracellular parasite toxoplasma gondii for periods of as long as 7 months were resistant to challenge with numbers of listeria monocytogenes and salmonella typhimurium that were uniformly lethal to normal mice. this resistance did not appear to depend on the strain of toxoplasma employed or the route of inoculation of either toxoplasma or bacteria. onset of immunity to listeria was demonstrable as early as 1 to 2 days after infection with toxoplasma. resistance to toxopl ...19684966746
