Description:Excerpt from Epitheliosis Infectiosa Avium, Vol. 20: January, 1916 This disease, owing to the variety of names which have been given it, has been much confused by a number of writers. Our experiments and experience with the disease prove quite conclusively that the so-called roup, chicken pox, diphtheria, canker are one and the same disease. Other investigators (Carnwath) succeeded in producing diphtheritic or croupous membranes in the mouth by pure pox material and pox lesions from the material taken from the diphtheritic or croupous membranes. These results have been substantiated by Schmid, Uhlenhuth, Manteufel and Ratz. Both forms of the disease are very frequently observed in the same flock of birds. During the warm months of the year or in warm climates, the prevailing, form is the pox lesions on the comb and wattles, while in the cold months or in a northern climate, the croupous or diphtheritic form predominates. Cohabitation of birds shows that a pox-infected bird introduced into a flock will produce either the croupous or diphtheritic form, or chicken pox; or vice versa, a fowl affected with the croupous or diphtheritic form will transmit the regular chicken pox. As experiment has shown the various types of the disease are but manifestations of a single clinical entity, and therefore the disease should be designated by one name. The name proposed by the writers is "Infectious Epitheliosis of Birds." Prevalency and Distribution of the Disease. The disease is found affecting nearly all birds, especially chickens, turkeys, peafowls, pheasants, guineas, pigeons, sparrows, quail, etc. It is not so frequently observed in ducks, geese and swans. The disease is widely distributed, appearing in practically all countries where birds are found in any considerable numbers. In the United States the disease is quite general, but more prevalent in the northern states, especially during the colder months. In the fall when the cold, damp weather begins outbreaks occur quite generally, and poultrymen often refer to the early inception of the disease as a cold. The intensity of the disease usually increases until the warm weather makes its appearance, when it diminishes and lies dormant, to reappear at the first cool, damp weather in the fall when the birds are more closely confined.
