BACKGROUND Acanthocephalans are fish parasites of worldwide distribution, penetrate their thorny proboscis into the intestinal wall of host and absorb nutrients. No diagnostic tool is available except postmortem investigations and identification by parasitologists. The aim of present study was to explore and assign taxonomical status to Pallisentis species prevalent in food fishes of river Gomt...

In an aquatic environment, there is a profound and inverse relationship between environment quality and disease status of fish. Parasites are one of the most serious limiting factors in aquaculture. Therefore, the present investigation has been undertaken to sort out the population dynamics of Pallisentis (Acanthocephala), in relation to host sex from freshwater fishes, Channa of Rohilkhand reg...

background: acanthocephalans are fish parasites of worldwide distribu-tion, penetrate their thorny proboscis into the intestinal wall of host and absorb nutrients. no diagnostic tool is available except postmortem inves-tigations and identification by parasitologists. the aim of present study was to explore and assign taxonomical status to pallisentis species prevalent in food fishes of river g...

The thorny headed acanthocephan, Pallisentis nagapurensis infects the intestine of fresh water murrel, Channa striatus. This parasite broughts severe histopathological changes in the intestine includes mucosa and submucosa are completely disrupted, thickened lamina propria, damage of epithelial cells, mucosa folds clumped. The intestinal villi of the mucosa shrinked, infected intestine often en...

BACKGROUND The genus Pallisentis is an endoparasitic acanthocephalan inhabiting the intestinal walls. Hooks and spines of the worm are significant taxonomical and adaptive tools. METHODS The parasites were fixed, dehydrated and examined under Olympus BX 53 Microscope with DIC attachment, digital camera and CELLSENS imaging system [Light microscopy (LM)] and fixed in 2% glutaraldehyde in 0.1 M...

Seven species of fishes, 6 species of mollusks, 1 species of crab, and 1 species of shrimp were collected from 12 natural freshwater sites from 5 provinces: Lumpang, Phrae, Phayao, Chiang Rai and Chiang Mai during the Rainy season of 2000. Fishes, Channa striatus, Dermogenus pusillus, Oxyeleotris marmoratus, Trichogaster trichopterus and Trichopsis vittatus were examined for helminths and 34.69...

Thirteen freshwater animals consisting of 8 species of fish, 1 species of shrimps and crabs and 3 species of mollusks collected during September 2000 from 8 sites in 4 districts of Chiang Mai Province: Hang Dong, San Pa Tong, Chom Tong and Hot were investigated for helminthes. Two metacercariae were recovered from 4 species of fish with the prevalence of 80.32%; Metacercariae of Stellantchasmus...

Thirty-six freshwater fish from Bung Borapet, a large reservoir, were examined for helminths in July 2005. The prevalence of infection was 19.44 (7/36) and the intensity was 4.67 (168/36) per fish. Seven fish were infected with 4 species of helminths: 1 trematode, Clinostomum philippinensis (metacercariae); 1 cestode, Senga chiangmaiensis; 1 acanthocephalan, Pallisentis sp and 1 nematode, Camal...

Previous research has shown that certain types of edible fish imported into Australia are infected with Euclinostomum/Isoparorchis digenetic trematodes. In the present study, Channa were examined for parasites which then morphologically identified to lowest taxonomic unit possible. Here we provide first Australian report Pallisentis sp. Van Cleave, 1928 (Prevalence (P) 35.9%) family Quadrigyrid...
