Detection of circulating antigen during acute infections with Toxoplasma gondii by enzyme-linked immunosorbent assay

Abstract

The serodiagnosis of toxoplasmosis is usually based on demonstration of antibodies by means of different serological methods. However, for confirmation of active toxoplasmosis, examination of paired sera is still needed. In this study a description is given of a sensitive enzyme method (enzyme-linked immunosorbent assay) with which it is possible to detect circulating antigens during the acute stage of mouse and human toxoplasmosis. Preliminary investigations of human sera suggested that circulating antigens are only found during a short period (active phase) of the toxoplasma infection and that they can be found in cases of fresh infections as well as during reinfections. The possible clinical relevance is discussed.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
