title: Observation of sutures in the oocyst wall of Eimeria tenella (Apicomplexa).
abstract: Eimeria tenella is the causative agent of caecal coccidiosis in chicken. Infection of chicken is initiated by ingestion of sporulated oocysts. The oocyst wall has two typical layers: a smooth outer layer formed by wallforming body I (WF I) and an inner layer originating from WF II. We observed that the inner layer is circumscribed by a hitherto undocumented linear suture and propose its role in the process of infection.
