A novel exo-antigen-based ELISA for the detection of canine leishmaniasis.

Dogs which are infected with leishmania parasites serve as major reservoir hosts for zoonotic visceral leishmaniasis. The incidence of zoonotic visceral leishmaniasis is rising in many countries. This may be associated with the continuing drift of people and their pets from rural areas into peri-urban settings, particularly at the fringe of large cities.

The utility of exoantigens for detection of Leishmania infections.

Exoantigens released by Leishmania promastigotes were the subject of a workshop held in Mombasa, Kenya. Investigators from the Walter Reed Army Institute of Research (Silver Spring, Maryland) met with scientists from government and academic institutes and industry to review the current global status of leishmaniasis and to explore the potential role of exoantigens in the detection of Leishmania in the vertebrate host and arthropod vector. Some encouraging data, particularly in the immunodiagnosis of leishmaniasis, were shared.

Assessment of assay sensitivity and precision in a malaria antibody ELISA.

Many types of ELISA-based immunodiagnostic test kits are commercially available in the market for specific indications. These kits provide necessary assay components, reagents, and guidelines to perform the assay under designated optimal conditions. By using these kits, any unknown or test sample can be assessed as negative or positive based on the results of referral calibrator (Ref+ve and Ref-ve) samples.
