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) assays were compared with the number of worms counted and the IgG titers at different times of infection. RESULTS: Data showed that ELISA using adult worm antigens (ELISA-SWAP) presented a satisfactory correlation between the absorbance value of IgG titers and the individual number of worms counted after perfusion technique (R\u00b2=0.62). In addition, ELISA-SWAP differentially detected positive samples with 30 and 60 days post infection (p=0.011 and 0.003, respectively), whereas ELISA using egg antigens (ELISA-SEA) detected samples after 140 days (p=0.03). CONCLUSIONS: These data show that the use of different antigens in immunological methods can be used as potential tools for the analysis of the chronological evolution of S. mansoni infection in murine schistosomiasis. Correlations with human schistosomiasis are discussed.<\/jats:p>","DOI":"10.1590\/s0037-86822012000400018","type":"journal-article","created":{"date-parts":[[2012,8,25]],"date-time":"2012-08-25T09:53:38Z","timestamp":1345888418000},"page":"505-509","source":"Crossref","is-referenced-by-count":7,"title":["Antigens of worms and eggs showed a differentiated detection of specific IgG according to the time of Schistosoma mansoni infection in mice"],"prefix":"10.1590","volume":"45","author":[{"given":"Rafaella Fortini Queiroz","family":"Grenfell","sequence":"first","affiliation":[{"name":"Funda\u00e7\u00e3o Oswaldo Cruz"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Watson Hermann","family":"Martins","sequence":"additional","affiliation":[{"name":"Funda\u00e7\u00e3o Oswaldo Cruz"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vanessa","family":"Silva-Moraes","sequence":"additional","affiliation":[{"name":"Funda\u00e7\u00e3o Oswaldo Cruz"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suedali Villas-Boas","family":"Barata","sequence":"additional","affiliation":[{"name":"Universidade Federal dos Vales do Jequitinhonha e Mucuri"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizandra Giani","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Funda\u00e7\u00e3o Oswaldo Cruz"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edward","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Centro de Pesquisas Ren\u00e9 Rachou"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulo Marcos Zech","family":"Coelho","sequence":"additional","affiliation":[{"name":"Funda\u00e7\u00e3o Oswaldo Cruz"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"575","DOI":"10.1016\/j.pt.2006.09.006","article-title":"Transmission control for schistosomiasis -
