Abstract

Immunoperoxidase staining of muscle infected with Trichinella spiralis for murine collagen types I and IV provided both qualitative and quantitative evidence of extensive synthesis of both types of collagen by fibroblasts in infected muscle compared to that seen uninfected muscle. Moreover, fibroblasts in muscle infected with T. pseudospiralis, a nonencapsulating species, showed significantly less staining for both types of collagen compared to muscle from mice infected with T. spiralis. Analysis of collagen composition of isolated nurse cells using an ELISA specific for either type I or type IV murine collagen suggested that of these 2 types of collagen, only type IV basement membrane collagen is found in Trichinella capsular collagen. Excretory/secretory products of T. spiralis and T. pseudospiralis induced extensive synthesis of exclusively type IV collagen by 3T3 murine fibroblasts in vitro.
