Immunological and Ultrastructural Characterization of True Histiocytic Lymphoma in the Northern Pike, Esox lucius L.1
An epidemic of a malignant neoplasm occurs in northern pike, /„vo.v lucius L., from the Aland Islands of Finland. The neoplasm is morpho logically similar to other pike hernie tumors reported in other areas of the world. Pike normal tissues showed evolutionary conservation with the mammalian intermediate filament proteins cytokeratin, desinili, vimentin, neurofilament protein, and glial fibri...
متن کاملImpact of pulp and paper mill effluent on egg hatchability of pike (Esox lucius L.).
Toxicants affect reproduction often at concentrations well below lethal levels. Also, the acidification of fresh waters has been shown to cause extinction of teleost fish populations usually through a failure of recruitment from younger generations. Both field and laboratory studies have documented that the greatest susceptibility to low pH occurs in the early developmental stages (e.g. Lee et ...

An epidemic of a malignant neoplasm occurs in northern pike, Esox lucius L., from the Aland Islands of Finland. The neoplasm is morphologically similar to other pike hemic tumors reported in other areas of the world. Pike normal tissues showed evolutionary conservation with the mammalian intermediate filament proteins cytokeratin, desmin, vimentin, neurofilament protein, and glial fibrillary ac...
متن کاملThe neoplastic cell type in lymphoreticular neoplasms of the northern pike, Esox lucius L.
The morphological characteristics of the cells of lymphoreticular tumors in the northern pike (Esox lucius L.) are described. The study was based on light microscopy of sections and imprints subjected to selected staining and histochemical procedures and on electron microscopy of thin sections. Neoplastic cells from tumors in different individuals as well as within a given tumor were remarkably...
متن کاملGenetic characterization of 18 novel microsatellite loci in northern pike (Esox lucius L.)
The northern pike (Esox lucius L.), an important predatory freshwater species, is undergoing significant population decline. In this study, 18 novel polymorphic microsatellite loci were isolated and used for assessing genetic variation in the Chinese Ulungur and Hungarian Balaton populations of the species. The number of alleles ranged from 2 to 13, observed heterozygosity from 0.154 to 0.920 a...
