| immunodiagnosis of entamoeba histolytica and ascaris lumbricoides infections in caucasian and aboriginal australians. | the immunodiagnostic efficiency of an indirect immunofluorescence test (ifat) and in vitro lymphocyte proliferative responsiveness (cell mediated immunity test, cmit) used to measure the immunological responses of individuals with known natural entamoeba histolytica and ascaris lumbricoides infections, was studied under survey conditions. e. histolytica was common among aborigines from cherbourg, kowanyama and central australia, but it was not found in brisbane caucasians. the protozoan was sele ... | 1986 | 2878514 |
| immunodiagnosis of parasitic zoonoses: comparative efficacy of three immunofluorescence tests using antigens purified by affinity chromatography. | three immunofluorescent antibody assays were developed during this study: the direct (dfat) and indirect (ifat) fluorescent antibody tests using frozen worm sections, and the cyanogen bromide indirect fluorescent antibody test (cnbr-ifat) using helminth antigens purified by affinity chromatography bound on to commercially prepared cnbr-sepharose 4b beads. purified antigens used in the cnbr-ifat gave greater specificity and sensitivity than either the dfat or ifat. dirofilaria immitis, toxocara c ... | 1978 | 354114 |
