| first observation of herpes-like virus particles in northern pike, esox lucius l., associated with bluespot-like disease in ireland. | circular whitish granular lesions, 5-12 mm in diameter, were observed on the skin and fins of a wild northern pike, esox lucius, caught in a lake in the republic of ireland. histological examination of the lesions revealed hypertrophied cells in the epidermis with deeply basophilic enlarged nuclei and dark-staining granular material in the cytoplasm. transmission electron microscopy of these cells revealed naked hexagonal herpes-like virus nucleocapsids (97 +/- 7 nm) in their nuclei while the cy ... | 2004 | 15357713 |
| epidermal hyperplasias of northern pike (esox lucius) associated with herpesvirus and c-type particles. | northern pike from several locations in central canada were observed to have two different types of hyperplastic epidermal lesions on the body and fins. one type of epidermal hyperplasia consisted of flat lesions, bluish-white in color with a granular or "gritty" appearance. histological examination of this granular lesion showed the presence of grossly hypertrophied cells surrounded by normal sized epidermal cells. the enlarged nuclei in thin section contained many typical herpesvirus capsids m ... | 1984 | 6320780 |
| genetic characterization of esocid herpesvirus 1 (eshv1). | blue spot disease, believed to be caused by esocid herpesvirus 1 (eshv1), has been observed in wild northern pike esox lucius in a number of cold-water locations, including the northern usa, canada, and ireland. in the spring of 2014, a northern pike was caught in wisconsin displaying the characteristic bluish-white circular plaques on the dorsum and fins. microscopic examination of hematoxylin and eosin-stained sections of the proliferative cutaneous lesions revealed a focally extensive abundan ... | 2016 | 27901499 |
