An epidemiologic study of tuberculosis in dogs exposed to humans with recently reported tuberculosis was undertaken in Philadelphia between July 1966 and June 1968. A total of 29 dogs meeting the criteria for inclusion in the high-risk population were studied by history, physical examination, intradermal tuberculin tests, and radiographic and bacteriologic examination. Ten of the 29 dogs showed positive responses to US Department of Agriculture (USDA) standard mammalian tuberculin. Positive tuberculin tests to second strength PPD were demonstrated in five of the 10 responders to USDA mammalian tuberculin. No physical, radiographic or bacteriologic evidence of tuberculosis was found in any of the high-risk animals examined. In a comparison group of 70 dogs without knwon exposure to tuberculosis, two positive responses to USDA tuberculin were demonstrated and none to PPD.
1966年7月至1968年6月期间，在费城对接触近期报告患有结核病的人类的犬类进行了一项结核病流行病学研究。通过病史、体格检查、皮内结核菌素试验、放射学和细菌学检查，对总共29只符合纳入高危人群标准的犬进行了研究。29只犬中有10只对美国农业部（USDA）标准哺乳动物结核菌素呈阳性反应。在对USDA哺乳动物结核菌素呈阳性反应的10只犬中，有5只对第二强度的PPD结核菌素试验呈阳性。在接受检查的任何高危动物中，均未发现结核病的体格、放射学或细菌学证据。在一组70只未接触过结核病的对照犬中，有2只对USDA结核菌素呈阳性反应，对PPD均无阳性反应。
