Fig. 3From: Early serodiagnosis of trichinellosis by ELISA using excretory–secretory antigens of Trichinella spiralis adult wormsOptical density values from the ELISA with adult worm ES antigens of mice infected with 100 T. spiralis muscle larvae. The cut-off value is represented by the dotted line. The window where the detection of anti-Trichinella IgG is not possible by ELISA with the muscle larval ES antigens is presented in greyBack to article page
