| [epidemiological aspects of malaria in 2 villages of the manyemen forest region (cameroon, southwest province)]. | in terms of parasitaemia in blood, the prevalence was 18.7% for plasmodium falciparum, 10.5% for p. ovale and 1% for p. malariae in the villages of mungo ndor and kokobuma. the plasmodial index of children from 2 to 9 years of age was 38.2% and the spleen index 26.6%, with a mean hackett score of 1.56. malaria is thus meso-endemic in the region. the immunofluorescent test performed with a p. falciparum antigen was positive in 66% of the children in the same age group. parasites were seen in 15% ... | 1986 | 3523108 |
| heterogeneity in the circumsporozoite protein gene of plasmodium malariae isolates from sub-saharan africa. | polymorphism of the circumsporozoite protein (csp) of plasmodium malariae was characterized by comparing gene sequences of twelve field isolates obtained in yaoundé, cameroon, central africa, and one clinical isolate originating from côte d'ivoire, west africa. the length of the csp gene ranged from 1266 to 1302 bp. the size polymorphism was due to variation in the number of tandem repeat units. all p. malariae isolates displayed a highly conserved 5' non-repeat region. seven non-synonymous and ... | 1998 | 9574911 |
