| phylogenetic relationships of trypanosoma chelodina and trypanosoma binneyi from australian tortoises and platypuses inferred from small subunit rrna analyses. | trypanosome infections are often difficult to detect by conventional microscopy and their pleomorphy often confounds differential diagnosis. molecular techniques are now being used to diagnose infections and to determine phylogenetic relationships between species. complete small subunit rrna gene sequences were determined for isolates of trypanosoma chelodina from the brisbane river tortoise (emydura signata), the saw-shelled tortoise (elseya latisternum), and the eastern snake-necked tortoise ( ... | 2001 | 11719959 |
