"Generalized tuberculosis" is a term applied in cases where a 

 part of the body is affected to which the tubercle bacilli can be 

 taken by the arterial blood only {e.g., spleen, kidneys, suprarenal 

 glands, testicles, ovaries, udder, bones, muscle, body lymph-glands, 

 central nervous system, eyes, etc.). The presence of numerous 

 foci in the lungs positively indicates infection of the blood and 

 therefore is quite indicative of generalized tuberculosis. 



What is " bob veal " ? How is it detected and is it deleterious to human 

 health? 

 "Bob veal" is immature veal (veal from calves under three 

 weeks of age) . The meat is watery, tender, easily torn, and grayish- 

 red in color ; shows only slight muscular development, especially in 

 the region of the upper shank. The tissue, which later develops as 

 the fat capsule of the kidneys, is (edematous, dirty yellow, or grayish- 

 red, and tough. The lumen of the navel vein is wide open and filled 

 with liquid blood. A chemical test will show an abnormal amount 

 of glycogen present in the muscles. 



It is generally considered that calves under three weeks of age 

 are unfit for human food, and our Federal regulations provide for 

 their condemnation. Yet, in Germany, calves only three to four 

 days old are frequently slaughtered for food, are considered a 

 delicacy, and apparently are not detrimental to the health of the 

 consumers.

Give the life-cycle of cystercus cellulosae. What disease does it cause? 

 What disposition should be made of a carcass affected with 

 this parasite? 

 The mature form of this parasite is the Taenia solium, a tape- 

 worm of man. The ova are passed in the feces and become dis- 

 seminated through the water or food and are taken in by the inter- 

 mediate host, the hog In the hog's stomach the ovum hatches into 

 a six-hooked embryo, which finds its way through the stomach and 

 intestinal walls and enters the muscular tissues. There it develops 

 into the larval stage, becomes encysted, and either perishes in time 

 or is eaten by man. If the cyst containing the living larva is eaten by 

 man, the larva becomes liberated and attaches itself, by means of its 

 booklets, to the intestinal wall and develops into the mature form.
