background: sickle cell disease (hbss) is a major health problem in nigeria and ma-laria has been implicated as a leading cause of morbidity/mortality in sickle cell disease patients. few reasons were put forward to explain the observed morbidity/mortality of hbss subjects due to plasmodium falciparum (p. falciparum) malaria. objectives: to determine the level of immunoglobulin classes (igm, ig...

Antigens encoded by the var gene family are major virulence factors of the human malaria parasite Plasmodium falciparum, exhibiting enormous intra- and interstrain diversity. Here we use network analysis to show that var architecture and mosaicism are conserved at multiple levels across the Laverania subgenus, based on var-like sequences from eight single-species and three multi-species Plasmod...

Plasmodium falciparum, the major cause of malaria morbidity and mortality worldwide, is only distantly related to other human malaria parasites and has thus been placed in a separate subgenus, termed Laverania Parasites morphologically similar to P. falciparum have been identified in African apes, but only one other Laverania species, Plasmodium reichenowi from chimpanzees, has been formally de...

In Japan, malaria has been successfully eradicated but imported malaria is still a great problem. Blood samples of malaria patients were collected from different hospitals of Japan. The samples were diagnosed by PCR based Microtiter plate-hybridization technique (MPH). The results of MPH were compared with microscopic diagnosis done at the laboratories of different hospitals. Among the total 23...

circumsporozoite protein (csp) is one of the stage specific antigens, which is used for the development of vaccines and to investigate the genetic diversity in plasmodium falciparum malaria parasite. polymerase chain reaction was used for typing of csp genes on 67 positive falciparum malaria patients from sistan and baluchistan province of iran. three fragments were detected for csp gene. twent...

We examined malaria cases reported to Ontario's public health surveillance systems from 1990 through 2009 to determine how temporal scale (longitudinal, seasonal), spatial scale (provincial, health unit), and demography (gender, age) contribute to Plasmodium infection in Ontario travellers. Our retrospective study included 4,551 confirmed cases of imported malaria reported throughout Ontario, w...

Abstract Background Malaria is an acute and chronic illness characterized by paroxysms of fever, chills, sweating, fatigue, anemia, and splenomegaly. Most malarial deaths occur in infants and young children.Anemia in malaria has diverse pathophysiologic mechanisms such as direct invasion of Red cells, In the following, we presented comparison of hematological aspects: children with Malaria an...

During pregnancy immunoglobulin G (IgG) antibodies are transferred from mother to neonate across the placenta. Studies in high transmission areas have shown transfer of P. falciparum-specific IgG, but the extent and factors influencing maternal-foetal transfer in low transmission areas co-endemic for both P. falciparum and P. vivax are unknown. Pregnant women were screened weekly for Plasmodium...

The genome sequence of the human malaria parasite, Plasmodium falciparum, was released almost a decade ago. A majority of the Plasmodium genome, however, remains annotated to code for hypothetical proteins with unknown functions. The introduction of forward genetics has provided novel means to gain a better understanding of gene functions and their associated phenotypes in Plasmodium. Even with...
