| [control of blood transfusion malaria in an endemic and in a non-endemic region in brazil]. | the aim of the present work was to establish appropriate criteria for screening of donor blood from regions with distinct malaria epidemiological characteristics. three locations with different screening criteria were studied: são paulo, sp (with no vectorial transmission), belém, pa (with low active transmission) and matupá and peixoto de azevedo, mt (with high active transmission). the malaria parasite--plasmodium sp--was searched for by "thick film", qbc test and antigen immunofluorescence te ... | 1998 | 9477695 |
| acquired immune responses to the n- and c-terminal regions of plasmodium vivax merozoite surface protein 1 in individuals exposed to malaria. | in this study, we evaluated the naturally acquired immune response to plasmodium vivax merozoite surface protein 1 (pvmsp1) in individuals with recent clinical episodes of malaria from the state of para, brazil. ten recombinant proteins representing the first 682 amino acids (aa) of the n-terminal region and one representing the final 111 aa of the c-terminal region were expressed in escherichia coli as glutathione s-transferase fusion proteins. both of these regions have been suggested as candi ... | 1997 | 9125537 |
