Malaria

Malaria is a life-threatening disease, which is caused by the protozoon Plasmodium spp. The transmission is mediated by the Anopheles mosquito, but can occur via blood transfusion also. Humans can be infected by four different species of Plasmodium: P. falciparum, P. vivax, P. ovale and P. malariae.

Infections with P. falciparum can be deadly. P. falciparum and P. vivax are the most common types. The disease occurs mainly in tropical and subtropical areas.

The Malaria infection induces the production of specific antibodies. In general they can be detected within some days after the occurrence of the parasites in the blood. The concentration of the specific antibodies is proportional to the intensity and duration of infection. The detection of antibodies is more sensitive than the direct detection of the pathogen and independent of the status of the infection. In humans who are infected for the first time the level of the specific antibodies decreases fast after recuperation. In contrast the antibody level decreases slowly (within 2 ? 3 years) in re-infected persons who move into non-endemic areas.

The NovaLisa? Malaria antibody assay is a fast and sensitive enzyme immunoassay for the detection of specific IgG and IgM antibodies against Plasmodium spp.

The microplate is coated with recombinant antigens of P. falciparum and P. vivax. P. ovale and P. malaria are also detected due to the antigenic similarity between the different Plasmodium species.

Specie of Plasmodium	Incubation Time	Type of Malaria	Fever Attack
P. falciparum	7-30 days (90%) Longer (10%)	Malaria Tropical	Inconsistent
P. malariae	16-50 days	Malaria Quartana	72 hours
P. ovale	12-18 days (90%) Longer (10%)	Malaria Tertiana	48 hours
P. vivax	12-180 days (90%) Longer (10%)	Malaria Tertiana	48 hours

Infections may be diagnosed by:

Microscopy: Direct detection and indentification of the pathogen is possible but uncertain

Serology: Determination of specific antibodies based on the ELISA-technique

NovaLisa^TM Malaria ELISA:

The NovaLisa^TM Malaria ELISA is intended for the qualitative determination of antibodies against Plasmodium in human serum or plasma (citrate).

Principal of the Assay

The qualitative immunoenzymatic determination of antibodies against Plasmodium is based on the ELISA (Enzyme-linked Immunosorbent Assay) technique.

Microtiter strip wells re pre-coated with Plasmodium antigens to bind corresponding antibodies of the specimen. After washing the wells to remove all unbound sample material hoseradish peroxidase (HRP) labeled anti-human IgG and IgM conjugate are added. This conjugate binds to the capture Plasmodium-specific antibodies.

The immune complecx formed by the bound conjugate is visualized by adding Tetramethylbenzidine (TMB) substrate, which gives a blue reaction product. The intensity of this product is proportional to the amount of Plasmodium-specific antibodies in the specimen. Sulphuric acid is added to stop the reaction. This produces a yellow endpoint color. Absorbance at 450 nm is read using an ELISA microwell plate reader.

Recombinant Antigen:

Recombinant CSP and MSP1 proteins from Plasmodium vivax and Plasmodium falciparum

Specific performance characteristics:

Intraassay			Interassay			Sensitivity	Specificity	Agreement
