That The Disease Was Caused: FMD' is caused and transmitted by a picorna virus (one of that the disease was caused smallest known disease-pro¬ducing organisms) of which that the disease was causedre are seven major types and at least 50 subtypes. that the disease was caused great variety of strains is both a bane and a blessing to that the disease was caused veterinarian. Each strain has its own idio-syncracies in such characteristics as antigenic-ity and resistance to control. that the disease was causedse differences, however, often aid that the disease was caused epidemiologist in pin¬pointing that the disease was caused geographic area from which that the disease was caused disease was transmitted.
Strangles (Distemper). Strangles is a respiratoi disease, primarily of young horses, caused by d bacterium Streptococcus equi and characterize by a nasal discharge of mixed mucus and pu with pus-filled abscesses in that the disease was caused lymph nodes < that the disease was caused head and neck.
that the disease was caused disease is transmitted by direct or ind rect contact and has an incubation period of 4 t 10 days. Early Signs are a rectal temperature c 104° F (40° C) or more, increased respiration coughing, depression, and poor appetite.See Also Disease Athero¬sclerosis:Coronary Heart Disease. Coronary heart disease is responsible for about 55% of all the deaths due to heart disease in the United States. It is caused by atherosclerosis of the coronary arteries, the small but vital blood vessels that supply the heart muscle with blood and oxygen. Atherosclerosis is the most common and most important kind of arteriosclerosis. The term "atherosclerosis" is derived from two Greek words, athero, meaning soft material or pudding, and sclerosis, meaning hardening. Both of these processes involve the inner lining, or endothelium, of the large and medium-sized arteries through¬out the body. It should be noted that young and middle-aged men are generally more prone to atherosclerosis than women. This is because women, until they reach menopause, are rela¬tively well protected by female hormones.
The coronary circulation undergoes a great deal of stress and strain due to the constant bending and straightening of the arteries with each beat of the heart. This wear and tear of the coronary arteries, combined with their small size, provides the background for the disease athero¬sclerosis which, when complicated by thrombosis (clotting), is such a menace to many young and middle-aged men. Connecting the three chief coronary branches are tiny arterioles that become functional only if the chief arteries be¬come narrowed. These tiny arterioles, under the pressure put on them, develop into a collateral circulation, which allows the blood to the muscle cells to bypass the blocked arteries. This col¬lateral circulation has saved countless lives.
On The Other Hand See Coronary Disease:Since coronary disease heart disease has become a leading cause of death in young and middle-aged men in the United States and since there is no really effective cure for it, either surgical or medical, it is essential that the causes of the disease be appraised so that preventive measures can be devised. Studies show that several factors are involved in coronary disease heart disease, with no single cause being entirely responsible, but the degree of responsibility of each of the many causes is not known.
The structural diagnosis of heart disease, both clinical and pathological, held the limelight until the time of Sir James Mackenzie who, at the end of the 19th century and during the be¬ginning of the 20th century, insisted on the addition of another category to the diagnosis of heart disease, namely that of function. This cate¬gory included degrees of competency, or suffi¬ciency, of the heart muscle to do the work re¬quired of it, and of the coronary disease circulation to supply the heart muscle with enough blood and oxygen to carry on its work. Among the disorders included in Mackenzie's category were congestive heart failure, which occurs when the heart mus¬cle does not function sufficiently; and coronary disease insufficiency, which occurs when the coronary disease arteries are obstructed by atherosclerotic thick¬ening of their walls or by blood clots. Also in¬cluded under the heading of disorders of function are the various cardiac arrhythmias, or irregular heartbeating. |
