Even though coccidiosis is a complex disease that can be caused by any combination of mainly seven species, most of the molecular researches concerning characterization of host and parasitegenes and proteins have been limited to Eimeria tenella. The present study describes isolation and purification of Eimeria necatrix oocysts that can be used for an inexpensive and simpletotal RNA extraction method to partial sequence determination of a cDNA encoding microneme 5 protein. Using the extracted total RNA as template and oligo(dT) as primer, cDNA was synthesized. In order to amplify cDNA encoding the micronem 5 protein (EnMIC- 5), RT-PCR was applied with the specific primers based on the known EST sequence.Following amplification, the unique and thick 758 bp fragment was seen. Domain analysis ofEnMIC-5 revealed that the sequence contains the conserved domain of PAN/APPLE superfamily between amino acid resides 130 to 201. This domain has strong similarity to theadhesive plasma pre-kallikrein. Despite sequence similarity of EnMIC-5 with those sequences in database, differences may represent some allelic polymorphism.}, keywords = {Eimeria necatrix,Microneme,RT-PCR}, url = {https://ijvst.um.ac.ir/article_25755.html}, eprint = {https://ijvst.um.ac.ir/article_25755_1dbe3686e5978376e7e0684402217307.pdf} }
