Plasmodium vivax multidrug resistance-1 gene polymorphism in French Guiana

Plasmodium vivax Malaria among Military Personnel, French Guiana, 1998–2008

We obtained health surveillance epidemiologic data on malaria among French military personnel deployed to French Guiana during 1998-2008. Incidence of Plasmodium vivax malaria increased and that of P. falciparum remained stable. This new epidemiologic situation has led to modification of malaria treatment for deployed military personnel.

Effects of Mefloquine Use on Plasmodium vivax Multidrug Resistance

Andes hantavirus (ANDV) causes hantavirus cardiopulmonary syndrome in Chile and is the only hantavirus for which person-to-person transmission has been proven. We describe an outbreak of 5 human cases of ANDV infection in which symptoms developed in 2 household contacts and 2 health care workers after exposure to the index case-patient. Results of an epidemiologic investigation and sequence ana...

Plasmodium falciparum with Multidrug Resistance 1 Gene Duplications, Senegal

To the Editor: Amplification and overexpression of the Plasmo-dium falciparum multidrug resistance 1 gene (Pfmdr1) have been associated with mefloquine resistance in P. Another isolate was obtained in a patient from Benin who did not respond clinically to mefloquine treatment (8). Pfmdr1 amplification has not been found in samples collected either before or after treatment for recurring P. falc...

analysis of plasmodium vivax merozoite surface protein-1 gene sequences

the emergence of plasmodium vivax in dashte moghan in northwestern iran has become a major concern for iranian's health officials. knowledge of genetic make up of the p. vivax populations in this area would give us an insight into the origin of the prevalent infections and the possible routes they are introduced. this paper reports the analysis of a variable region between the two interspecies ...
