| newborn splenic volumes vary under different malaria endemic conditions. | ultrasound was used to measure newborn splenic dimensions and calculate the volumes in a malarious and a non-malarious region of papua new guinea. the median splenic volume of infants born in madang, where malaria transmission is high throughout the year, was 5.2 cm3/kg, while that of infants born in goroka, where malaria is not endemic, was 2.6 cm3/kg. the cause of this difference is unknown, but possible explanations include fetal exposure to malaria antigens in utero and the high incidence of ... | 1989 | 2665658 |
| malaria in adult outpatients at goroka hospital during 1986. | of 206 adult outpatients attending goroka hospital with suspected malaria during 1986, 40.3% had blood slides positive for malaria (28.2% plasmodium falciparum, 13.6% p. vivax and 1.9% p. malariae). parasite densities and proportions of cases with gametocytes were higher than observed in endemic regions. acquisition of infection during recent coastal travel was implicated in the majority of cases (86%). 6 out of 13 gametocyte carriers tested were infectious to anopheles farauti mosquitos. anti-m ... | 1989 | 2683479 |
| the population structure of plasmodium falciparum and plasmodium vivax during an epidemic of malaria in the eastern highlands of papua new guinea. | although most of the papua new guinea highlands are too high for stable malaria transmission, local epidemics are a regular feature of the region. few detailed descriptions of such epidemics are available, however. we describe the investigation of a malaria epidemic in the obura valley, eastern highlands province, papua new guinea. of the 244 samples examined by microscopy, 6.6% were positive for plasmodium falciparum only, 9.4% were positive for plasmodium vivax only, and 1.2% were mixed infect ... | 2002 | 12479544 |
