Publisher's Synopsis
Excerpt from The Elimination of Tubercle Bacilli From Infected Cattle
Of the eighty-seven examinations of the milk from individ ual cows, tubercle bacilli were not found microscopically or by guinea-pig inoculations, except in two cases, and these were samples of milk from the cows whose udders were affected. These were the only cows that showed any clinical evidence of disease and at the time the specimens were taken the lesions in the udders were not thought to be of a tuberculous nature. Tubercle bacilli were present in very large numbers in the milk from each of these cows. They were largely outside of the tissue cells, lying free between the leucocytes and fat globules of the milk. In two specimens acid fast or timothy bacilli were present in very small numbers. They were decolorized with acidulated alcohol and guinea-pigs inoculated from these samples did not develop tuberculosis. If we exclude the two cases in which there were udder lesions, tubercle bacilli were not found in any of the samples. If they were included, a little over two per cent of the examinations were positive. The thirty-six examinations of the feces failed to reveal the presence of tubercle bacilli, either microscopically or by animal inoculation. One specimen contained a few acid fast organisms. The guinea-pigs inoculated from this specimen did not develop tuberculosis. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
