Abstract
During a 2 year study of air-borne tuberculosis, infection was transmitted to 71 animals. Seventy-seven patients participated in the study. Of the 48 animal infections which were cultured and in which drug-resistance studies were done, it was found that 35 of the infections had been caused by 3 patients. Possible reasons for the remarkable infectivity of these 3 patients are discussed. It is suggested that this infectivity was related to the patients'' ability ot produce large numbers of bacilli unsually capable of withstanding the rigors of air-borne transmission.
