| the interaction between plasmodium falciparum and p. vivax in children on espiritu santo island, vanuatu. | studies of the prevalence and incidence of malaria were conducted in children < 10 years old living in 10 rural villages on the island of espiritu santo, vanuatu, south-west pacific. malaria prevalence remained stable at 30% throughout the year but the relative contributions of the 2 major species were highly dependent on season. plasmodium falciparum predominated in the long wet season (november-may) and p. vivax in the dry season (june-october). case definitions for malaria, derived using a mu ... | 1996 | 9015495 |
| genetic restriction of plasmodium falciparum in an area of stable transmission: an example of island evolution? | to date, a high degree of polymorphism has been demonstrated at both the msp1 and msp2 loci in parasites from areas of stable malaria transmission. as a consequence, in such areas it is rare to find parasites of the same 2-locus genotype in more than 1 subject. we have studied msp1 and msp2 diversity in parasites collected from subjects with both symptomatic (n = 86) and asymptomatic (34) malaria living on the island of santo, vanuatu, an area of stable malaria transmission. polymorphism at the ... | 2000 | 10811274 |
