During 2010-2012, an outbreak of 210 cases of malaria occurred in Tumbes, in the northern coast of Peru, where no Plasmodium falciparum malaria case had been reported since 2006. To identify the source of the parasite causing this outbreak, we conducted a molecular epidemiology investigation. Microsatellite typing showed an identical genotype in all 54 available isolates. This genotype was also...
Study of host pharmacogenetics can improve our knowledge of mechanisms of drug resistance selection and spread. This issue has recently been addressed with respect to chloroquine and amodiaquine in malaria endemic areas of West and East Africa. Here we report, from surveys performed in two different areas of Uganda, that the human CYP2C8*3 allele, which had been reported to be strongly associat...
Artemisinin derivatives are first-line antimalarial drugs in Thailand. No firm evidence of clinically relevant artemisinin resistance exists. When used as monotherapy, artesunate has been associated with a high treatment failure (recrudescence) rate, which could be due to low-level artemisinin resistance. To understand the causes of recrudescence, we retrospectively studied a cohort of 104 mala...
Drug resistance is probably the greatest challenge to most malaria-control programs. Given the limited resources for other malarial-control measures, rational drug used is crucial. Molecular markers for parasite resistance such as pfcrt, pfmdr-1, and dhfr have the potential to be used in an integrated fashion to provide timely information that is useful to policy makers. Therefore, we evaluated...
Artemisinin resistant falciparum malaria is an increasing problem in Southeast Asia, but has not been associated with increased transmission of the disease, yet. During a recent outbreak in 2014 in Ubon Ratchatani, Eastern Thailand, parasites from 101 patients with falciparum malaria were genotyped for antimalarial drug resistance markers. Mutations in the Kelch13 marker for artemisinin resista...
