Two species of Myxobolus are reported from the gills of Mugil cephalus collected at Goa, India: M. goensis n. sp. and M. parvus Shulman, 1962. Myxobolus goensis n. sp. forms digitiform or rounded plasmodia between the gill rakers. Their spores are oval in frontal view, with tapered anterior extremity, and lemon-shaped in lateral view, measuring 9.7 (9.5-10.5) microm in length, 6.6 (6-7.5) micro...

Myxobolus mississippiensis n. sp. is described from gill lamellae of the bluegill (Lepomis macrochirus) inhabiting the Pascagoula River System, Mississippi. Fresh spores measure 16.4-18.7 microns long, 3.9-6.2 microns wide, and 4.7-6.2 microns thick. Spore width to length ratio is 1:3.2. Polar capsules are 5.5-7.8 microns long and 1.5-2.3 microns wide, with 9-10 filament coils that when extrude...

The phylum Myxozoa Grassé, 1970, consists of a heterogenous group of around 50 genera that are worldwide disseminated in a wide variety of aquatic media. In the present study, 43 specimens of Pimelodus ornatus were collected from an adjacent area to the Cachoeira do Arari municipality on Marajó Island, in the Brazilian state of Pará, in 2013. Macroscopic analysis showed the presence of whitened...

During a survey on the myxosporean fauna of gibel carp Carassius auratus gibelio (Bloch) in China, a species of Myxobolus Bütschli, 1882 that did not conform to any known species was found. The species is characterised by the presence of round to ellipsoidal plasmodia of 2.6-4.0 mm in diameter in the palate of host. Mature spores are obovate in frontal view and lemon-shaped in lateral view, wit...

Three species of Myxobolus (Myxozoa, Myxosporea) occur in heart tissue of centrarchids. Myxobolus paralintoni Li and Desser, 1985 from Lepomis gibbosus in Algonquin Park and in Lake Erie, Ontario, has subcircular spores (in plane of spore length) in frontal view (11-13 microm long, 9-10 microm wide, and 5 microm thick) with a width-to-length ratio of 1:1.2. Myxobolus jollimorei n. sp. from Lepo...

Little is known about the viability of myxozoan actinospore stages after harvest from laboratory cultures of infected oligochaete worms. The viability and reactivity of actinospores of three myxozoan species was evaluated after short-term storage at 4 degrees C and 12 degrees C. Two methods of determining actinospore viability were compared: differential fluorescent staining and direct microsco...

The present communication describes three new species of myxosporeans (Myxozoa: Myxosporea: Bivalvulida), Myxobilatus odontamblyopusi sp. n., Myxobolus catmrigalae sp. n. and M. buccoroofus sp. n. from Odontamblyopus rubicundus (HamiltonBuchanan), Catla-Mrigal hybrid carp [male parent fish Catla catla (Hamilton-Buchanan) × female parent fish Cirrhinus mrigala (Hamilton-Buchanan)] and Labeo bata...

During a recent investigation of parasites infecting fishes from the Okavango River and Delta, Botswana (southern Africa) fourteen sharptooth catfish, Clarias gariepinus (Burchell, 1822) (Siluriformes: Clariidae) were examined for the presence of myxozoan infections. Results revealed the presence of two species of the genus Henneguya Thélohan, 1895 and one species of the genus Myxobolus Bütschl...

During health surveys of 7- to 9-week-old goldfish (Carassius auratus L.) fingerlings in a fish farm near Budapest, Hungary, myxosporean plasmodia were observed on the fins. Plasmodia were most frequently found at the intersegmental joints of the finrays. Spores of Myxobolus diversus Nie et Li, 1973 known from China, were detectable in the mature plasmodia located within the lumen, and less oft...

survey on developmental stages of myxobolus karuni and m. persicus in the gills of barboid fishes from mezopotamian part of iran was done. a total 296 fish specimences were examined. random sampling was carried out during 2002- 2004 from karoun, karkheh rivers and shadgan lagoon. the fishes transported alive to the laboratory, their gills were fixed and stained. myxobolus karuni developed histo...
