XXXX of the mucosa of the ethmoid in domestic animals.

@entity1707 @entity5 @entity189 @entity11189 @entity291
The @entity189 of the mucosa of the ethmoid was reported in all domestic animals but specially in @entity291 and @entity1707 in India. The @entity5 mass extended from the ethmoid to the nasal cavity and obturated the respiratory tract hence the clinical manifestation reported. Retropharyngeal and parotidal lymphnodes showed by metastases. The tumoral transformation was observed in the cells of the ethmoid mucosa. An early diagnosis could be done by sampling of cells in the nasal mucus. The disease was reproduced by instillation of cellular extracts. Several viruses have been isolated from the @entity5 tissue. In @entity1707 there was a correlation between the incidence of @entity5 and the use of @entity11189 contaminated feed. This was an enzootical problem for the herd but neither genetics or microbial factors are determined. Various attempts were made to control the @entity5 growth.
