Myxobolus taibaiensis sp. n. was found in the inner intestinal wall of common carp, Cyprinus carpio Linnaeus, during the investigation of fish parasite fauna in Lake Taibai, located in the middle reach of the Yangtze River, China. The whitish ellipsoidal plasmodia, up to 2.9 mm long and 1.7 mm wide, developed in the circular muscle layer of the intestinal wall and produced significant compression into adjacent tissues, but no significant inflammatory responses were observed against this infection. Mature spores are oval in frontal view and lemon-like in lateral and apical view, averaging 10.2-11.2 µm (10.8 ± 0.2 µm) in length, 9.1-9.9 µm (9.6 ± 0.2 µm) in width and 6.1-6.6 µm (6.3 ± 0.1 µm) in thickness. Polar capsules are pyriform, equal in size, slightly converging anteriorly, measuring 4.4-5.4 µm (5.0 ± 0.2 µm) in length by 3.2-3.6 µm (3.4 ± 0.1 µm) in width. Polar filaments coiled with four to five turns and arranged perpendicular to the polar capsule length, measuring up to 106 µm. Myxobolus taibaiensis sp. n. is morphologically similar to Myxobolus rotundatus Achmerov, 1956 which also infects the inner wall of the intestine of common carp. However, the small subunit ribosomal DNA sequence identity was only 94%, generally beyond the intraspecies variation in the genus. Phylogenetically, this new species is sister to M. rotundatus and then clusters with M. shantungensis Hu, 1965 to form an independent common carp-infecting cluster within the Henneguya-Myxobolus clade.

Myxobolus koi is a type of parasite that infects many freshwater fish through myxospores, resulting in a disease called myxobolosis. This research aimed is to investigate the clinical symptoms that occur in the gills of infected Koi carp (C. carpio). The utilized methods in this study are molecular detection, histopathology, and Scanning Electron Microscopy (SEM). Koi carp samples that are suspected to be infected with Myxobolus koi show several clinical signs, such as swollen and pale-colored gills and gill covers (opercula) that do not close completely, as well as white spots that appear on the edge of the lamella. The results of this study showed that through histological observations, there were changes characterized by hyperplasia of the primary lamella cartilage that envelops parasitic cysts and the encapsulation process that surrounds the cysts by gill cartilage in infected fish; SEM showed oval and elongated spores of a size of ± 12 µm (800x). The DNA template from gill tissues in clinically infected and uninfected fish was examined by PCR testing with primers ERB 1 (Forward) and ERB 10 (Reverse); the results of electrophoresis in infected fish were detected at 2000 bp.
