lizardfish is one of the economically important fishes of persian gulf. in recent years, white, ellipsoid, round or elongated nodules were found in body cavity of this fish species which in preliminary microscopic examination were recognized as microsporidia. to determine the approximate prevalence rate of microsporidian infection and to establish its taxonomic position, 50 lizardfish were boug...
A new microsporidia Glugea sardinellensis n. sp. found in the teleost fish Sardinella aurita Valenciennes collected from the Tunisian coasts. The parasite develops in a large xenomas measuring 1–16 mm in diameter and is generally visible with naked eye in the connective tissue around the pyloric caeca of the host. Xenoma were often rounded, but would be occasionally ovoid or irregular shape, ge...
A new microsporidian species of the genus Glugea Thélohan, 1891 parasitising the marine teleost fish Cephalopholis hemistiktos Rüppell, collected from the Red Sea in Saudi Arabia, is described on the basis of microscopic and molecular procedures. Spherical and whitish xenoma were observed adhering to the intestinal wall. The numerous spores contained within these xenoma, were ovoid to pyriform ...
The microsporidian species Glugea anomala, G. stephani, G. americanus and Spraguea lophii were compared by using sequence data derived from their small subunit rDNA genes which were amplified by polymerase chain reaction and directly sequenced. These sequence data and published data of G. atherinae were analyzed and were used to infer a phylogenetic tree. The 5 microsporidian fish parasites app...
During the implementation of current research entitled “Study diet, growth, reproduction, and determination concentrations some trace elements in Alosa fallax (Lacépède, 1803) marine waters Lattakian coast”, we found parasite Glugea sp. inside one caught on 7/24/2023 AD from Ras Al-Baseet area (35.8524° N, 35.8378° E) using Purse nets. Infection with In colonies yellowish-white masses over dige...
A new microsporidium was observed in the flying fish Cypselurus pinnatibarbatus japonicus (Franz) (Exocoetidae) from Yakushima, Japan. Visual examination revealed the microsporidium to form white elongate nodules in the host's trunk muscle. Monomorphic spores were ovoid to pyriform in shape, with average dimensions of 4.1 x 2.2 microm and possessing a polar tube describing 13-15 coils. Histolog...
Juvenile English sole (Parophrys vetulus) utilize Yaquina Bay, Oregon as a nursery during at least a portion of their first year of life, but the possibility of the existence of additional nursery grounds offshore has not previously been examined. During 1971, young-of-the-year first appeared in Yaquina Bay in February, were abundant from April to September, and most emigrated to offshore areas...
Recent field studies carried out in lacustrine environments have suggested that fish schools may be assorted with respect to parasite infections, but the generality and strength of parasite-assortative schooling in fish is unclear. In this study, data are presented on the body size and externally visible macroparasite load of 366 individual three-spined sticklebacks Gasterosteus aculeatus L. (G...
