| seasonal variation of anti-resa/pf155 plasmodium falciparum antibodies in three localities from the state of amapá, brazil. | anti-resa/pf155 antibodies were assayed in sera of individuals from three localities (laranjal do jari, vila padaria and vila paraíso) in the state of amapá, brazil, during the long-rains and short-rains seasons. all of these had negative blood smears for malaria. most of the sera collected were positive in indirect fluorescent antibody (ifa) with p. falciparum parasites, with no seasonal variation. a high percentage of these sera (62% to 100%) was resa positive by modified indirect fluorescent ... | 1994 | 7855488 |
| [the evolution of in-vitro resistance in plasmodium falciparum to antimalarials in a gold-prospecting area in the state of amapá between 1983 and 199)]. | this study evaluates the sensitivity of p. falciparum in vitro to antimalarial drugs in an area of gold mining exploration in amapá state during the period of 1983 to 1990. the following tests were done, 75 in vitro studies with chloroquine and quinine, 74 with amodiaquine and 76 with mefloquine. the results showed 81% of resistance to chloroquine and 27% to amodiaquine while resistant strains to quinine and mefloquine were found. also for these two quinolinomethanols a loss of sensitivity was n ... | 1993 | 8159821 |
| [the evolution over time of the in-vitro resistance of plasmodium falciparum to antimalarial drugs in 2 areas of the brazilian amazonia with distinct socioeconomic and geographic characteristics]. | we evaluated the temporal progression of in vitro p. falciparum resistance to chloroquine, amodiaquine, quinine and mefloquine in two areas with distinct socioeconomical and geographical characteristics: lourenço, in amapá state and paragominas, in pará state. the former region is essentially an "open" gold mining camp, whereas the latter is one currently undergoing a colonization settlement process, in addition to expanding economical activities which mainly include cattle raising and wood expl ... | 1995 | 8668836 |
| seasonal variation of anti-plasmodium falciparum antibodies directed against a repetitive peptide of gametocyte antigen pfs2400 in inhabitants in the state of amapá, brazil. | antibodies to the pfs2400 gametocyte antigen have been shown to inhibit the development of plasmodium falciparum in anophelines and therefore this antigen is a candidate for a transmission-blocking vaccine. to test seasonal variation of these antibodies under field conditions, sera from 72 individuals were collected twice, first during the long-rains season with low malaria transmission and then, 6 months later, during the short-rains season, when transmission is high. this study was conducted i ... | 1997 | 9088430 |
| [malaria control in brazil: 1965 to 2001]. | this paper reviews malaria control initiatives in brazil, from the malaria eradication campaign (campanha de erradicação da malária), which was launched in 1965 and was based on spraying dichlorodiphenyltrichloroethane (ddt) and on administering antimalarial drugs, to the implementation, in 2000, of the program for intensification of malaria control in the nine-state legal amazon region of brazil (plano de intensificação das ações de controle da malária na amazônia legal), which was implemented ... | 2002 | 12049032 |
| molecular screening of plasmodium sp. asymptomatic carriers among transfusion centers from brazilian amazon region. | the transmission of malaria in brazil is heterogeneous throughout endemic areas and the presence of asymptomatic plasmodium sp. carriers (apcs) in the brazilian amazon has already been demonstrated. malaria screening in blood banks is based on the selection of donors in respect to possible risks associated with travel or residence, clinical evidence and/or inaccurate diagnostic methods thereby increasing the probability of transfusion-transmitted infection. we evaluated the frequency of apcs in ... | 2007 | 17384812 |
