DNA sequences of alleles at the merozoite surface antigen-1 (MSA-1) gene locus of the malaria parasite Plasmodium falciparum show evidence of repeated past recombination events between alleles. These include both (1) nonreciprocal recombination events that have homogenized certain gene regions among alleles and (2) reciprocal recombination events that have combined allelic segments with diverge...

Merozoites of the malaria parasite Plasmodium falciparum expose at their surface a large multiprotein complex, composed of proteolytically processed, noncovalently associated products of at least three genes, msp-1, msp-6, and msp-7. During invasion of erythrocytes, this complex is shed from the surface except for a small glycosylphosphatidylinositol-anchored portion originating from MSP-1. The...

The malaria parasite Plasmodium falciparum invades erythrocytes where it replicates to produce invasive merozoites, which eventually egress to repeat the cycle. Merozoite surface protein-1 (MSP1), a prime malaria vaccine candidate and one of the most abundant components of the merozoite surface, is implicated in the ligand-receptor interactions leading to invasion. MSP1 is extensively proteolyt...

background: haemonchosis has a negative effect on the farming industry throughout the world, especially in the tropic and sub-tropic countries. the present study was carried out to differentiate haemonchus species from its main hosts in iran, including sheep, goat and camel.   methods: the identification took place based on the morphometrics of the spic-ules and molecular characters. two hundre...

The human malaria is widely distributed in the Middle East, Asia, the western Pacific, and Central and South America. Plasmodium vivax started to have the attention of many researchers since it is causing diseases to millions of people and several reports of severe malaria cases have been noticed in the last few years. The lack of in vitro cultures for P. vivax represents a major delay in devel...
