Page 354 - As would be expected, the heads were not readily detected in the necrotic masses contained in the larger nodules, but were almost invariably seen in the smaller ones. In a few sections the tapeworm could be traced through the mucosa to the nodule in the muscular tissue in which its head appeared. In the earlier stage of the nodular development there is a cell Infiltration about the head of the worm. This process continues until the infiltrated tissue reaches a considerable size. The worms attached...
Page 354 - The larger nodules were of a pale or dark-yellowish color, while the smaller ones varied in shade from the more highly colored areas to the neutral gray of the normal serosa. To the touch they gave the sensation that would be expected if the subserous and muscular coats were closely studded with small, oval, solid bodies. The mucosa presented similar elevations. Attached to the mucosa over the nodules were a number of tapeworms. There were also in the more advanced cases a variable number of small...
Page 354 - The smaller nodules contained a more purulent-like substance and the smallest appeared to the naked eye as areas of infiltration. Sections of the affected intestine showed upon microscopic examination that the heads of the tapeworms had penetrated the mucous membrane and were situated in different layers of the intestinal wall. They were frequently observed between vllll.
Page 232 - A broad, thin muscle arises, on each side, from the anterior margin of the pubis ; and its fibres pass forwards, diverging as they go, to be inserted into the ventral face of the posterior part of the pericardium and into the ventral and lateral parts of the fibrous capsule of the stomach, passing between that organ and the adherent posterior face of the liver, and being inserted into the fibrous aponeurosis which covers the anterior face of the stomach, and represents the oblique septum.
Page 355 - States of North Carolina and Virginia, shows that the Infesting cestode is quite widely distributed in this country. It Is highly probable that the total loss it occasions, both from deaths and from the shrinkage of poultry products, due to the chronic course of the disease It produces, is very large. DIAGNOSIS. — Tuberculosis is, as before stated, the only known disease for which this affection is liable to be mistaken, and it is of much Importance that the two diseases should not be confounded....
