“…Although they infect fish species belonging to several taxonomic orders, there are more descriptions among the Perciformes (Sarkar 1999;Ali 2000;Abdel-Ghaffar et al 2008;Karlsbakk and Køie 2011). Ortholinea auratae Rangel et al, 2014 was recently described infecting the urinary bladder and posterior kidney of the gilthead seabream, Sparus aurata Linnaeus, 1758, with a prevalence of infection of 51.6 % (Rangel et al 2014).…”

Actinospores released from the marine oligochaete Limnodriloides agnes inhabiting a Southern Portuguese fish farm are molecularly recognized as developmental stages of the life cycle of Ortholinea auratae, a myxosporean parasite that infects the urinary bladder of Sparus aurata. The molecular analysis of the 18S rRNA gene reveals a similarity of 99.9 to 100 % of the actinospores analyzed to the myxospores of O. auratae. The actinospores belong to the triactinomyxon morphotype and occur in groups of eight within pansporocysts that develop in the intestinal epithelium of the oligochaete host. This is the first record of a myxosporean using an oligochaete as its invertebrate host in the marine environment.

“…Myxosporea infecting Egyptian fish is a group of parasites which is considered as the major harmful cause of myxosporidiosis which is the major harmful agent of fish life (El-Mansy and Bashtar 2002;Abdel-Ghaffar et al 2009, 2011Morsy 2010). River Nile fish in Egypt were examined for myxosporean parasites in different localities by some authors (Fahmy et al 1975;Imam et al 1987;Abdel-Ghaffar et al 1995a;Abdel-Ghaffar et al 1998;Ali 1998Ali , 1999Ali , 2000Ali 1999). During this study, a preliminary survey of Myxosporea was carried out on some fish from the River Nile at El Minia Governorate, Egypt.…”

Myxosporidian parasites infecting fish are very dangerous parasites causing severe damage to a large number of economically important fishes especially in aquaculture. A survey of myxosporean parasites infecting four species of fishes from the River Nile in Egypt is conducted. One hundred and ninety-five out of 316 fish specimens with a percentage of 61.7% were found to be naturally infected with these parasites. Light microscopic examination of different tissues revealed the presence of 12 myxosporean species belonging to the family Myxobolidae. Four of the identified species are novel and the other eight species are redescribed. Myxidium sp.nov. a coelozoic species inhabiting the gallbladder of Labeo niloticus with its mature spores float free in bile was detected. These spores possess a fusiform, straight, or slightly crescentic shape with less pointed ends and two equal polar capsules. Three novel histozoic Myxobolus species infecting Oreochromis niloticus were identified. Myxobolus sp(1).nov. is a species inhabiting kidney tissue with ovoid spores exhibiting a small intercapsular appendix. Myxobolus sp(2).nov. and Myxobolus sp(3).nov. recovered from kidney and intestinal tissues. Spores of Myxobolus sp(2).nov. are elliptical in shape with an anterior end wider than posterior one. Their two polar capsules are ovoid to pyriform occupied nearly the first third of the spore body. Spores of Myxobolus sp(3).nov. are broader than long with nearly rounded or ovoid two polar capsules. Eight species of the recovered myxosporean parasites are redescribed, Myxobolus niloticus Fahmy et al., 1971 from pectoral, dorsal, and tail fins of L. niloticus, Henneguya suprabranchiae Landsberg, 1987, and Henneguya branchialis Ashmawy et al., 1989 are recovered from the gills and suprabranchial organ of the catfish Clarias gariepinus, respectively, Myxobolus naffari Abdel-Ghaffar et al., 1998 and Myxobolus imami Ali et al., 2002 are found in the kidney of Barbus bynni and L. niloticus, Myxobolus caudatus Ali et al. & Parasitol Res (2002) from Tail fin of B. bynni, Myxobolus fomenai Abdel-Ghaffar et al., 2008 from kidney and intestinal tissues of O. niloticus, Thelohanellus niloticus Abdel-Ghaffar et al., 2012 are observed in the gills of L. niloticus.

“…In Africa, the work in the ®eld of Myxosporea is still rudimentary with about 100 species currently known from the continent (Fomena and Bouix 1997). River Nile ®sh in Egypt were ®rst examined for myxosporean parasites by Fahmy et al (1975), then by Imam et al (1987), Abdel Ghaar et al (1995a, b;1998), Ali (1998Ali ( , 1999Ali ( , 2000 and Ali et al (1999). During this study, a survey of Myxosporea was carried out on some ®sh from the River Nile.…”

Six Myxobolus species are described from Nile ®sh, ®ve of which are new and one is redescribed: M. naari Abdel Ghaar et al., 1998 was recovered from the gills of Labeo niloticus and the mouth of Barbus bynni; M. caudatus sp. n. was observed in the tail ®n of B. bynni; M. fahmii sp. n. occurred in the gills of B. bynni; M. imami sp. n. was found in the kidney of L. niloticus; M. intestinalis sp. n. was recorded from the intestine of B. bynni; and M. perforata sp. n. was found in the internal surface of the operculum of Hydrocynus forskalii. The histological eects of some of the Myxobolus infections present are described. ResultsAll the examined ®sh were found to harbor myxosporean infection except Tetradon fahaka and Mormyrus kannume.
