| ceratomyxa seriolae n. sp. and c. buri n. sp. (myxozoa: myxosporea) from the gall-bladder of cultured yellowtail seriola quinqueradiata. | ceratomyxa seriolae n. sp. and c. buri n. sp. (myxozoa: myxosporea) were found in the gall-bladder of cultured yellowtail seriola quinqueradiata temminck & schlegel (carangidae) in japan. mature spores of c. seriolae n. sp. were elongate and 6.5 (6.0-7.5) microm long and 33.7 (28.0-41.5) microm thick. disporous plasmodia of c. seriolae n. sp., 40-100 microm in size, were amoeboid to spherical. c. buri n. sp. were elliptical with a flattened posterior end. 6.5 (5.5-7.5) microm long and 14.3 (11.0 ... | 2001 | 11252275 |
| molecular diagnosis of myxobolus spirosulcatus associated with encephalomyelitis of cultured yellowtail, seriola quinqueradiata temminck & schlegel. | mass mortality of cultured yellowtail, seriola quinqueradiata, has recently been reported from fish farms in western japan. previous studies revealed that diseased fish were characterized by encephalomyelitis and presporogonic stages of a myxosporean-like parasite in the spinal cord. however, the parasite has remained unidentified because of the lack of mature stages being present. thus, in the present study, analysis of the small subunit ribosomal dna (18s rdna) of the parasite as well as in si ... | 2010 | 21091721 |
