Column: Sleepless in the liver: would revisiting the past give any directions on how to deal with hypnozoite carriers of P. vivax?

February 6, 2014 - 20:51 -- Bart G.J. Knols
Many of the recent strategies to improve malaria control have been focusing on improving the detection of very low parasitaemias to identify asymptomatic carriers of Plasmodium sp. to reduce the infective reservoir. Although these strategies are extremely rational and sensible to tackle most of malaria infections, they will probably not be sufficient to achieve elimination for parasites that present relapses, as is the case for Plasmodium vivax. The need to look for new and sophisticated methods has been exhaustively stressed by researchers, however, at this time, revisiting a simple and efficient strategy successfully employed in the past could prove to be a path to be followed...

To date, this is the most complete report on molecular characterization of P. vivax and P. falciparum field isolates in Honduras with regards to genetic diversity. These results indicate that P. vivax and P. falciparum parasite populations are highly diverse in Honduras despite the low level of transmission.
