Amazonian Anopheles with low numbers of oocysts transmit Plasmodium vivax sporozoites during a blood meal.

Anopheles darlingi is the main malarial vector in the Brazilian Amazon region. An. nuneztovari s.

Long-lasting infectivity of Plasmodium vivax present in malarial patient blood to Anopheles aquasalis.

Experimental studies for understanding the relationship between Plasmodium vivax and its vector hosts are difficult, because of to the lack of a long-term, in vitro continuous culture system unavailability of infected blood samples, seasonality of the disease, and the concentration of most cases in remote areas. This study evaluates the duration of the infectivity of P. vivax to Anopheles aquasalis after collecting blood from malaria-infected patients.

Purification Methodology for Viable and Infective Plasmodium vivax Gametocytes That Is Compatible with Transmission-Blocking Assays.

Significant progress toward the control of malaria has been achieved, especially regarding Plasmodium falciparum infections. However, the unique biology of Plasmodium vivax hampers current control strategies. The early appearance of P.
