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...
A blood stage-induced P. brasilianum infection in a naive squirrel monkey induced antibodies which reacted with the circumsporozoite protein of the parasite. Titers increased with duration of infection and persisted for 3 months after cure. In an immunoblot, these antibodies detected two polypeptides with molecular weights identical to those of the circumsporozoite protein and its precursor.
BACKGROUND The RTS,S/AS01 vaccine targets the circumsporozoite protein of Plasmodium falciparum and has partial protective efficacy against clinical and severe malaria disease in infants and children. We investigated whether the vaccine efficacy was specific to certain parasite genotypes at the circumsporozoite protein locus. METHODS We used polymerase chain reaction-based next-generation seq...
Sporozoites are an invasive stage of the malaria parasite in both the mosquito vector and the vertebrate host. We developed an in vivo assay for mosquito salivary gland invasion by preparing Plasmodium gallinaceum sporozoites from infected Aedes aegypti mosquitoes under physiological conditions and inoculating them into uninfected female Ae. aegypti. Sporozoites from mature oocysts were isolate...
We produced a hybridoma secreting an immunoglobulin G1 monoclonal antibody against the circumsporozoite protein of the human malaria parasite Plasmodium malariae (Uganda 1/CDC). The monoclonal antibody produces a circumsporozoite precipitation reaction when incubated with viable sporozoites of P. malariae and reacts at high titers with heat-fixed sporozoites in an indirect immunofluorescent ant...
BACKGROUND The RTS,S/AS01 malaria vaccine targets the circumsporozoite protein, inducing antibodies associated with the prevention of Plasmodium falciparum infection. We assessed the association between anti-circumsporozoite antibody titres and the magnitude and duration of vaccine efficacy using data from a phase 3 trial done between 2009 and 2014. METHODS Using data from 8922 African childr...
Malaria vaccines containing the Plasmodium falciparum Circumsporozoite protein repeat domain are undergoing human trials. There is no simple method to evaluate the effect of vaccine-induced responses on P. falciparum sporozoite infectivity. Unlike the rodent malaria Plasmodium berghei, P. falciparum sporozoites do not infect common laboratory animals and only develop in vitro in human hepatocyt...
Malaria, one of the world's most common diseases, is caused by the intracellular protozoan parasite known as Plasmodium. In this study, we have determined the evolutionary relationship of two single-copy proteins, circumsporozoite protein (CSP) and merozoite surface protein-1 (MSP-1), among Plasmodium species using various bioinformatics tools and softwares. These two proteins are major blood s...
