The presence of P. vivax infection in Duffy-negative individuals was investigated in a cross-sectional study conducted in Anajas, Archipelago of Marajo, State of Para, which is an area of malaria transmission in the Brazilian Amazonia.
This novel method effectively purifies viable malaria sporozoites by greatly reducing contaminating mosquito debris and microbial burdens associated with parasite isolation
We report the unique case of a 19-year-old nonimmune patient with Plasmodium vivax monoinfection, confirmed by PCR in the peripheral blood and in the spleen section, who was splenectomized due to spleen rupture two days prior to the diagnosis and treatment of the malarial infection
A newborn of 26 days, born in Lisbon, Portugal, presented with fever, anaemia and thrombocytopaenia. She was admitted considering neonatal sepsis, but Plasmodium vivax was identified in the second peripheral blood smear performed. Parenteral quinine was started with good evolution.
Molecular surveillance has great potential; however, it requires preliminary local studies in order to properly interpret the emerging patterns in the context of elimination.
G6PDd is widespread and spatially heterogeneous across most MECs where primaquine would be valuable for malaria control and elimination.
In this study, genetic analysis was performed on Plasmodium vivax and Plasmodium falciparum parasites isolated from peripheral and placental blood in pregnant women living in north-west Colombia, and compared with parasites causing acute malaria in non-pregnant populations.
Plasmodium vivax is the predominant species of the human malaria parasite present in the Indian subcontinent. There have been recent reports on Chloroquine (CQ) resistance and severe manifestations shown by P. vivax from different regions of the world including India. This study focuses on Bikaner, India where during the last few years there have been continuous reports of severe manifestations by both Plasmodium falciparum and P. vivax.
We cloned and characterized three domains of PvAMA-1 gene from an Iranian patient.
A few cases of Plasmodium vivax malaria in which anophelines of subgenus Kerteszia were incriminated as vectors have been reported outside the Amazon region, in the Atlantic Forest.
