Not illustrated. 1906 Excerpt: ...of the intestinal contents by bacteria, aid in the formation of the calculi. Usually the larger examples are single; but of the smaller sizes there may be dozens or hundreds in one intestine. In addition to pressure erosions caused in the mucous membrane by these calculi, they may produce fatal results, especially by accidental impaction and obstruction at some narrow part of the intestinal tube. (For details cf. Spezielle pathol. Anatomic d. Hausticrc, II. Aufl. 1902, Stuttgart, Enke's Verlag.) Horses which take in sand and mud in drinking from pools (and the same is true of hogs from swallowing ground while rooting) occasionally get large masses of such material into the intestine and may as a result suffer from the formation of diverticula. In pigs bristles which are swallowed may be massed together in the intestine by the peristaltic movements into cylindrical bristle balls; in ruminants hair which has been swallowed may form in the abomasum one or more spherical, felt-like bunches, and in the same way remnants of plant fibres may also be compressed into similar balls here (piHconcrements, phytoconcrcmcnts, bezoars). Fig. 41. Cut surface of half of an enterolith from hone (one-half reduced). Pus concretions result from the inspissation of pus retained in old abscesses and other places, possibly with more or less calcification. In the air chambers of horses they are met quite commonly, supposed to be due to the compression of thick streptococcus pus by muscular pressure (movements of chewing and swallowing), often into chestnut-like or potato-like masses. In cattle tuberculous caseated masses in bronchiectatic cavities may form hard lumps, perhaps reaching the size of a fist, Gout. This name is applied to a disturbance of metabolism characterized by accu...
