摘要

The original description of Henneguya pellis, a myxozoan parasitizing blue catfish Ictalurus furcatus, is supplemented with new data on histopathology, spore morphology, and 18S small subunit (SSU) ribosomal DNA (rDNA) sequence. Plasmodia presented as both internal and external, raised, cyst-like lesions on the body wall of the peritoneal cavity and on the skin. The cysts contained numerous elongate, lanceolate myxospores, flattened parallel to the suture line. The spore body was 14.8 ± 1.1 µm (range 13.0–17.1) long and 4.8 ± 0.8 µm (range 4.0–7.4) wide in frontal view. The caudal appendages were 77.7 ± 8.8 (range 57.4–96.4) in length. There were 2 pyriform polar capsules, unequal in length, with the longer capsule measuring 7.2 ± 0.6 µm (range 6.2–8.4) in length and the shorter capsule measuring 6.5 ± 0.5 µm (range 5.5–8.0). The polar capsules were not significantly different in width, measuring 1.7 ± 0.2 µm (range 1.4–1.9). There were 8 turns in the polar filament coil. The total length of the spore was 92.5 ± 9.2 µm (range 73.3–113.5). Spore morphology and site of development are similar to that of Henneguya sutherlandi from channel catfish; however, 18S rDNA sequence data support previous findings that identify H. pellis and H. sutherlandi as 2 distinct species.
