| molecular characterization of the trichomonas gallinae morphologic complex in the united states. | forty-two trichomonas gallinae isolates were molecularly characterized to determine whether isolates differed in genetic sequence of multiple gene targets depending on host species or geographical location. the 5.8s ribosomal rna (rrna) and flanking internal transcribed spacer (its) gene regions were amplified by polymerase chain reaction, and the sequences were analyzed phylogenetically. the results of the sequence analysis strongly suggest at least 2 species may exist within the t. gallinae mo ... | 2008 | 18576862 |
