EXPERIMENTALLY INDUCED CHANGES IN NASAL MUCOUS SECRETORY SYSTEMS AND THEIR EFFECT ON VIRUS INFECTION IN CHICKENS

Abstract

Chickens 3 wk old, inoculated intranasally with a mesogenic (moderately virulent) strain of Newcastle disease virus, developed necrotic lesions of the mucous acini, predominantly of the middle turbinates. The infection subsequently spread to involve much of the rest of the mucosa, including mucous and ciliated epithelial cells, and other acini.
