Antigens of worms and eggs showed a differentiated detection of specific IgG according to the time of Schistosoma mansoni infection in mice

Abstract: Introduction:The correlation between the immunological assay and the antibody titer can offer a tool for the experimental analysis of different phases of the disease. Methods: Two simple immunological assays for Schistosoma mansoni in mice sera samples based on specific IgG detection for worms soluble antigens and eggs soluble antigens were standardized and evaluated in our laboratory. Fifty mice were used in negative and positive groups and the results obtained by enzyme-linked immunosorbent assays (ELISA) as… Show more

“…Although the antigenic composition is not the same as the live worm, the use of SWAP or SWA constitutes a valuable experimental tool to evaluate many aspects of immune responses promoted by different host cells (Xu et al ., 2014 ; Zhu et al ., 2014 ). This antigen is the easiest to obtain and is essentially an extract based on Tris-HCl or phosphate-buffered saline from mixed male and female worms and prepared in various ways, either by homogenization, sonication or freeze/thaw (or a combination of these) (Grenfell et al ., 2012 ; Neves et al ., 2015 ). Some studies have demonstrated that SWAP could induce an M1-like profile (Xu et al ., 2014 ; Zhu et al ., 2014 ).…”
