Histoplasma capsulatum Darling 
Disease.—Histoplasmosis, an infectious mycosis that usually results 
in a pulmonary disease of man. 
Cockroach.—Periplaneta americana, U.S.A., Texas (O. B. McShan, 
1953): 24 hours after the insects had been fed an inoculated meal, 
they showed no evidence of fungus invasion as determined by fecal 
cultures and inoculation into mice. The organism could be detected in 
the cockroaches’ intestinal contents 30 minutes after inoculation, but 
thereafter all pools were negative.
