Leucopenia associated with abalone viral ganglioneuritis
The bird died, and postmortem findings included mild, nonsuppurative encephalitis and degenerative encephalopathy; lymphoplasmacytic myenteric ganglioneuritis
(particularly of the proventriculus); and wallerian degeneration of the sciatic nerves.
Brain tissue from a yearling steer with an encephalomyelitis and ganglioneuritis
of unknown origin was analyzed by using viral metagenomics, which showed a divergent astrovirus distantly related to an ovine astrovirus.
Final report: costs -benefit analysis of implementing alternative techniques for rehabilitating reefs severely depleted by the abalone viral ganglioneuritis
Proventricular impaction associated with nonsuppurative encephalomyelitis and ganglioneuritis
in two Canada geese.
Histopathologic examination of bird 1 identified typical lesions of PDD with a moderate multifocal encephalitis (Fig 1) and mild myocarditis, adrenalitis, and ganglioneuritis
of the intestine.
The abalone fishery in Australia has also declined throughout the past few years, but, in this case, the decline was associated with the outbreak of a disease, abalone ganglioneuritis
, which caused mass mortalities in Victoria (Mayfield et al.
Definitive diagnosis of PDD requires demonstration of lymphoplasmacytic ganglioneuritis
in the intestinal tract.
Impaction of the cloaca can result from a variety of causes, including failure to pass an egg, intrinsic disease of the cloacal wall, loss of muscle tone due to viral-induced ganglioneuritis
(eg, PDD), (1) and a cloacolith.
ABSTRACT The Tasmanian abalone biosecurity project was initiated by the Department of Primary Industries, Parks, Water and Environment (Wild Fisheries) and the Tasmanian wild abalone industry in response to an outbreak of abalone viral ganglioneuritis
in the Victorian abalone fishery during late 2005.
The disease is characterized by nonsuppurative ganglioneuritis
of the vegetative nerve plexuses of the crop, proventriculus, gizzard, and duodenum.
ABSTRACT Between May 2006 and February 2010, abalone viral ganglioneuritis
caused by abalone herpes virus (AbHV) spread along the coast of Victoria, Australia, and devastated wild abalone populations, causing high mortality (up to 90% in some areas).
