Methods: After serial dilutions of H. meleagridis, a single parasite was taken and cultured at 40ˇăC. Its proliferation was checked by microscopy, and an 18S rRNA gene fragment of H. meleagridis was amplified using specific primers (Hmf/Hmr) and sequenced. The sequences were assembled manually and aligned using the Clustal X 1.81 program. Results: Two tubes showed proliferation of parasites and, after infection with parasites from these tubes, acute histomoniasis was rapidly induced in turkeys. 18S rRNA gene fragments of the two strains were 492 and 495 base pairs in length, respectively, and the sequence homologies with known H. meleagridis sequences were both 99.4%. Sequence homology between these two strains was 99.6%, and the variation between the two sequences and Trichomonas was more than 20%. Conclusion: We conclude that microculture can produce high-purity and highly pathogenic H. meleagridis.
