| detection of specific antibodies to plasmodium falciparum in blood bank donors from malaria-endemic and non-endemic areas of venezuela. | malaria antibody detection is valuable in providing retrospective confirmation of an attack of malaria. blood bank screening is another area were malaria serology is potentially useful. in the present study, we tested the presence of antibodies to plasmodium falciparum in sera from blood bank donors of non-endemic and malaria-endemic areas of venezuela. sera from 1,000 blood donors were tested by an indirect immunofluorescent antibody (ifa) assay and an igg-elisa for the presence of malaria anti ... | 1999 | 10403326 |
| a rapid malaria appraisal in the venezuelan amazon. | while the federal state of amazonas bears the highest risk for malaria in venezuela (2007: 68.4 cases/1000 inhabitants), little comprehensive information about the malaria situation is available from this area. the purpose of this rapid malaria appraisal (rma) was to provide baseline data about malaria and malaria control in amazonas. | 2009 | 20003328 |
| pfmdr1 amplification and fixation of pfcrt chloroquine resistance alleles in plasmodium falciparum in venezuela. | molecular tools are valuable for determining evolutionary history and the prevalence of drug-resistant malaria parasites. these tools have helped to predict decreased sensitivity to antimalarials and fixation of multidrug resistance genotypes in some regions. in order to assess how historical drug policies impacted plasmodium falciparum in venezuela, we examined molecular changes in genes associated with drug resistance. we examined pfmdr1 and pfcrt in samples from sifontes, venezuela, and integ ... | 2010 | 20145087 |
| malaria seroprevalence in blood bank donors from endemic and non-endemic areas of venezuela. | in venezuela, a total of 363,466 malaria cases were reported between 1999-2009. several states are experiencing malaria epidemics, increasing the risk of vector and possibly transfusion transmission. we investigated the risk of transfusion transmission in blood banks from endemic and non-endemic areas of venezuela by examining blood donations for evidence of malaria infection. for this, commercial kits were used to detect both malaria-specific antibodies (all species) and malaria antigen (plasmo ... | 2011 | 21537669 |
