Title

Kinetics Evaluation of IgM and IgG Levels in the Mice Infected with Trichinella spiralis Experimentally Using ES Antigens from Different Developmental Stages of the Parasite

Pages

  223-230

Abstract

 Background: To assay the Trichinella-specific IgM and IgG antibody responses during the early stage of infection, serum was collected from mice infected with the muscle larvae (ML) of T. spiralis (ISS534) at different dpi (days post infection) up to 60 days. Methods: The levels of IgM and IgG antibodies in serum were measured by ES antigens from different stage of T. spiralis using the ELISA method in Shanghai, China in 2017. Results: The anti-Trichinella IgM and IgG could be detected by ES antigens from the adult three days worm (Ad3) as early as 5 dpi and 8 dpi, respectively. ES antigens from the mixture of adult six days worm & new born larvae (Ad6+NBL) was similar to Ad3. When antibodies were detected by these two antigens, the levels of IgM peaked at 14 dpi and then declined from 15 dpi to 60 dpi; the IgG peaked at 20 dpi, and gradually declined, however, higher detection levels were maintained until 60 dpi. Conclusion: Ad3 ES antigens showed more antigenicity than Ad6+NBL ES on titer detection of IgM and IgG antibodies, and the production of Ad3 ES is easier. In terms of early diagnosis, these two antigens are better than the ML ES antigens of T. spiralis, which antibodies could not be detected before 20dpi. Ad3 ES antigens might be good candidate for the early diagnosis of trichinellosis or the mixture of Ad3 and Ad6+NBL ES might be used.
