Objective: Diagnosis causative agent of nodular lesions in gizzard. Design: Case report.
Animals: Indigenous birds.
Procedure: At necropsy of indigenous birds, nodular lesions in the gizzard together with helminths were observed. For parasitological examination, the isolated helminths were treated
with lactophenol solution and for histopathological exmination of the nodular lesions, tissue samples were stained with Haematoxilan and Eosin (H&E).
Results: In parasitological examination of the isolated helminths, based upon morphological and size characteristics, the parasites were identified as Cheilospirura hamoulosa. In histopathological exmination of the nodular lesions, inflammatory reactions with infiltration of lymphocytes and macrophages were observed along with hyperplastic changes in the glandular region of gizzard. Conclusion: Cheilospirura hamoulosa is able to produce nodular
lesions in gizzard of indigenous birds. J. Fac. Vet. Med. Univ. Tehran. 58,4:375-376,2003.
