| morphology and 18s rdna of henneguya gurlei (myxosporea) from ameiurus nebulosus (siluriformes) in north carolina. | henneguya gurlei was isolated from ameiurus nebulosus captured in north carolina and redescribed using critical morphological features and 18s small-subunit ribosomal rna (ssu rdna) gene sequence. plasmodia are white, spherical, or subspherical, occur in clusters, measure up to 1.8 mm in length, and are located on the dorsal, pectoral, and anal fins. histologically, plasmodia are located in the dermis and subdermally, and the larger cysts disrupt the melanocyte pigment layer. the spore body is l ... | 2008 | 18372621 |
