STREPTOMYCIN IN TUBERCULOSIS Experimental studies by Feldman and Hinshaw16have demonstrated that streptomycin has a powerful effect in inhibiting the growth of tubercle bacilli in experimental tuberculosis of guinea pigs. Many pigs can be saved by treatment and in 30 per cent the organisms cannot be isolated from the organs of the surviving animals. Cooke, Dunphy and Blake17have reported a bacteriologic and clinical recovery in a patient with tuberculous meningitis. This observation demonstrates the striking effect of streptomycin on the tubercle bacillus. In a report to the Committee on Chemotherapeutics and Other Agents on June 12, 1946 Dr. Hinshaw discussed the results of his studies of streptomycin in patients with various forms of tuberculosis. His comments, which were based on observations made during one and a half years, can be summed up as follows: Seventy-five patients have been studied. Three patients with miliary
