TEXT 19. TUBERCULOSIS

1. Read and translate the following text from English into Russian using the wordlist.

This is a chronic contagious disease of man and animals. Of the latter cattle, hogs, and poultry are the commonly affected ones. Man, poultry, and the remaining groups of animals are each most easily infected by their own specific bacillus of tuberculosis (Mycobacterium tuberculosis). Thus the human, avian, and mammalian strains are recognized. There is also intercommunicability of the germ so that man may also contract the cattle infection; swine may contract the cattle, human and avian (poultry) infection. Infection takes place by the consumption of tuberculosis-germ contaminated liquid and solid food, and by breathing germ laden air.

The symptoms of tuberculosis in animals vary greatly, depending upon the infected organ or organs. If the disease is in the lungs there may be a cough; in the intestines, chronic diarrhea; in the brain, nervous symptoms; in the udder, swellings; in the joints, and testicles, enlargement; and if the disease is of very long standing there is usually evidence of unthriftiness. A very important point is that infected animals may show no outward signs of the disease, many of them seem to be perfectly healthy.

A diagnosis of tuberculosis in infected animals may be established by the inoculation method, and by a reaction to a tuberculin test. Vaccination against tuberculosis of man and animals has been tried.
