During a survey of insect nematodes from Manipur, two new species ofnematodes parasitic in the hindgut of mole cricket Gryllotalpa africana were recovered. The two newspecies are designated as Cameronia triovata sp. nov. and Cameronia manipurensis sp. nov. C.triovata sp. nov. is characterized by presence of three eggs (more…)
The ultrastructure of the spermatozoon of Calliobothrium verticillatum(Cestoda, Tetraphyllidea, Oncobothriidae) parasite of the smoothhound shark, Mustelus mustelus L.(Pisces, Carcharhiniformes), was studied by transmission electron microscopy. (more…)
Pseudogilquinia pillersi (Southwell, 1929), a poorly known species oftrypanorhynch, is redescribed from plerocerci collected from Epinephelus coioides (Hamilton, 1922),Epinephelus malabaricus (Bloch et Schneider, 1801) (Serranidae) and Plectropomus laevis (Lacepede,1801) (Serranidae) off New Caledonia.

A new species of Acanthocolpidae, Stephanostomum adlardi is described fromthe serranid Plectropomus leopardus from Lizard Island in the northern Great Barrier Reef. Itdiffers from all previously described acanthocolpids in the structure of the oral sucker which isextended into dorsal and ventral lobes each bearing a row of spines. (more…)
An examination of specimens of Anas georgica Gmelin (Anatidae) from Regiondel Bio-Bio and Region del Maule, Chile, revealed the presence of two digenean species reported forthe Holartic Region: Australapatemon burti (Miller, 1923) Dubois, 1968 (Strigeidae) andParamonostomum pseudalveatum Price, 1931 (Notocotylidae).

Pseudorhabdosynochus bacchus sp. nov. (Diplectanidae) is described from thegills of the whitespotted grouper Epinephelus coeruleopunctatus collected off New Caledonia, SouthPacific, and is the first monogenean reported from this fish. (more…)
The Gyrodactylus fauna of 274 fish taken from ten salmonid farms in Polandwas sampled in 2006. Four fish species were investigated: rainbow trout Oncorhynchus mykiss, browntrout Salmo trutta (morphs fario, lacustris, and trutta), grayling Thymallus thymallus and huchenHucho hucho. (more…)
BACKGROUND: Absolute criteria for grading oligodendrogliomas are somewhatpoorly defined in contrast to those for grading astrocytic tumors, and cytologic features ofanaplastic oligodendrogliomas have been poorly described. CASE: A 63-year-old man presented with atoppling gait. Radiologic examination revealed a 7-cm mass with calcifications in the right frontallobe. Intraoperative smears of the tumor showed hypercellular, loosely cohesive cell clusters andsingle cells with nuclear pleomorphism, numerous apoptotic cells and no discernible fibrillaryprocesses.
