myxozoans are an economically important group of microscopic parasites best known for the diseases they cause in commercially important fish hosts. the classification of myxosporeans is generally based on the morphology of their myxospores. without molecular data, it is very difficult to identify new or existing species. dna sequence information is therefore, a prerequisite to taxonomic and phy...

Fieldwork was conducted in 1998 and 1999 in the Okavango River and Delta and a total of 275 fishes representing 31 species were examined for the presence of myxosporean parasites. A total of seven myxosporeans of the genus Myxobolus Bütschli, 1882 were found infecting the fishes. Two new species namely Myxobolus etsatsaensis sp. n. from Barbus thamalakanensis Fowler, 1935 and M. paludinosus sp....

The demand for tilapia fishing goods has recently expanded on a national scale. One of the difficulties this fish farming operation encountered was parasite-caused illness. aims study were to explore parasites in (Oreochromis niloticus) from local seller Dramaga, Bogor, West Java. A total 14 sampled, with an average length 22 cm and body weight 195 grams. Fish gills, pectoral fins, caudal tail ...

In the last few years two factors have helped to significantly advance our understanding of the Myxozoa. First, the phenomenal increase in fin fish aquaculture in the 1990s has lead to the increased importance of these parasites; in turn this has lead to intensified research efforts, which have increased knowledge of the development, diagnosis. and pathogenesis of myxozoans. The hallmark discov...

in this paper, the metazoan parasite community system of capoeta damascina in the tigris basin (mesopotamian region) in the middle-east is presented. overall, 54 species have been identified. between 2005 and 2008, iranian surveys of capoeta damascina found a total of 47 metazoan parasites species, most identified to species level. in addition, 6 parasite species from iraq and 1 species from oc...

myxosporeans are best known for the diseases they cause in commercially important fish species. identification of myxosporeans at the species-level is mainly based on conventional methods. the 18s rrna gene sequence of morphologically identified myxobolus orissae infecting the gill lamellae of mrigal carp cirrhinus mrigala was characterized in the present study. the plasmodia of m. orissae were...

As new pathogenic strains are emerging and threatening aquaculture development, myxosporeans (Myxozoa) are receiving much attention in recent years. Myxosporean taxonomy is traditionally based on morphology of the myxospore stage. Molecular data on Indian myxosporeans are rare. In this report, the 18S rRNA gene sequence of Myxobolus cuttacki infecting gill lamellae of minor carp Labeo bata (Ham...

Abstract Myxosporidiosis is an infectious disease caused by myxozoans of the Phylum Cnidaria, Class Myxosporea, and Order Bivalvulida, considered a common parasite in fresh saltwater fishes that parasitize many organs, especially gills. In present study, 49 specimens belonging to eight genera: Tetragonopterus, Leporinus, Myleus, Pirinampus, Rhapiodon, Pygocentrus, Ageneiosus, Serrasalmus were c...

Myxobolus buri sp. n. is described from the brain of yellowtails, Seriola quinqueradiata T. et S. with serious scoliosis. The sites of infection were the cerebral cavities and the surfaces of the olfactory lobes , optic lobes and medulla oblongata, Spores of the species were differentiated from those of the other mem bers of the genus Myxobolus on the basis of a through recording of their shape...

We studied a natural infection of the oligochaete Branchiura sowerbyi Beddard, 1892 with the Raabeia-type actinosporean stage of Myxobolus lentisuturalis Dyková, Fiala et Nie, 2002 which infected goldfish Carassius auratus auratus (L.) in Italy, using molecular analysis of the SSU rRNA gene. The existence of intraoligochaete development shows that this parasite follows the life-cycle pattern de...
