Greater larval food supply led to enhance larval and production and larger mosquitoes with longer longevity and higher biting frequency.
Results of this study provide evidence that Pv200L is a naturally immunogenic fragment of the PvMSP-1 and is associated with the degree of exposure to parasites.
This study suggests that urban and periurban areas of this municipality are highly susceptible to epidemic malaria, which is endemic in the Yanomami Indian reservation near the city.
The frequently observed mild outcomes of falciparum malaria in many places of the Amazon area prompted us to ask whether a globally restricted variant (var) gene repertoire is present in currently circulating and older isolates of this area.
Here, the potential for allele-specific polymorphisms in this population is investigated, and the allele-specificity of antibody responses to PfMSP119kD are determined.
Here we describe high rates of P. vivax recurrence (26–40% 180 days after treatment) in two cohorts of rural Amazonians exposed to low levels of malaria transmission after a vivax malaria episode treated with chloroquine-primaquine.
The results suggest propagation of mixed infections by multiple inocula, not super-infection, implying decade-long opportunity for outcrossing in these mixed infections.
Using a rapid malaria appraisal method, the objective of the study was to provide baseline data about malaria and malaria control in Amazonas State. The authors conclude that malaria control is possible, even in tropical rain forest areas, if the health system is working adequately.
