| asymptomatic carriage of malaria parasites in blood donors in yaoundé | background: malaria can be transmitted through blood transfusion, but there is paucity of data concerning transfusion-transmitted malaria in cameroun. objective: to determine prevalence of malaria infection and association with epidemiological and clinical data obtained from donors' responses. methods: microscopic examination of stained thick and thin blood smears for the detection, quantification and specification of plasmodium sp was performed on 493 blood donors in two main hospitals in yaoun ... | 2011 | 22141368 |
| identification and typing of cameroonian isolates of p. malariae using monoclonal antibodies against p. brasilianum. | in the present study, monoclonal antibodies raised against plasmodium brasilianum were used to demonstrate, for the first time, antigenic diversity in natural populations of plasmodium malariae isolates and as diagnostic tool to detect low parasitaemia p. malariae infection. seventeen mcabs reacting by indirect immunoflorescence antibody (ifa) assay with no other plasmodium species than p. brasilianum, were shown to react with p. malariae and were used for typing 29 p. malariae isolates from hyp ... | 2006 | 16962978 |
| 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 |
