TUBERCULOSIS 151 beginning they are largely referable to the organ affected. , There are, however, certain general manifestations that appear in most of the advanced cases, such as emaciation while the appetite continues good. This is always a suspicious indication and especially ii accom- panied by cough, rough coat and tight, harsh skin. Rough or loud respiratory sounds are sus- picious, and, in advanced cases, it is often found that the ani- mal groans when pressure is brought to bear upon the chest wall. Many cases bloat habitually due to presence of enlarged glands upon the eso- phagus. Enlarged superficial lymph glands are suspicious but there are other causes for enlargement of these glands. In tuberculosis of the lungs, it may be said that coughing is the most noticeable symp- tom. It is most common after feeding, drinking, or after rapid moving following a â period of repose, but some- times it occurs without any apparent cause. The cough is usually strong, dry and fre- quently of a high pitch. Sometimes it is very violent, accompanied by protrusion of the tongue. Auscultation re- veals modified and abnormal sounds of different kinds in the lungs; sibilant, sonorous and mucous rales are most common. A dull sound is often detected on percussion. It is also to be noted that this con- dition is of slow development and long duration, thus aiding one to distinguish it, in many cases, from bronchitis or pneumonia. Where the mediastinal lymphatic glands are enlarged and press upon the esophagus the animal bloats more or less. Chronic or habitual bloating accompanied by a good appetite and no other evi- dence of disease of the digestiye tract, especially if there is shortness of. Fig. 26.
