OBJECTIVE: To study genetic polymorphism of DNA on seven isolates of Trichomonas vaginalis.
METHODS: The random amplified polymorphic DNA (RAPD) technique was performed to amplify genomic DNA of the seven T. vaginalis isolates, including Beijing 1, Beijing 2, Chengde, Tangshan, Jiujiang 1, Jiujiang 2 and Jiujiang 3. The DNA bands detected were analyzed by clustering analysis with SPSS software.
RESULTS: The percentage of genetic similarity among the seven isolates was from 77.4% to 94.7%, showing a close genetic relationship among them. The percentages between the isolates of Beijing 1 and Tangshan, Jiujiang 1 and Jiujiang 2, Beijing 2 and Jiujiang 3 were 89.2%, 92.1% and 94.7% respectively, while that of Jiujiang 1 and Chengde was 77.4%, indicating a lower homology.
CONCLUSION: There are a close genetic relationship and certain gene polymorphism among the seven T. vaginalis isolates; geographical origin plays little role to the genetic characteristics.
