Studies on the Pathogenic Fungus of Mycotic Granulomatosis—II.

Some of the Note on the MG-fungus

Abstract

Experiments on the effect of dilution of fish meat extract in the FME agar on the growth of MG-fungus revealed that the fungus grew best on the FME agar which consisted of 10% w/v fish meat extract plus 1.5% Difco agar.
The MG-fungus grew well on the FME agar at 15 to 30°C, but failed to grow at 5 and 37&degC. It grew in the FME broth at the pH range 5 to 10.
Chloramphenicol, malachite green, cycloheximide and NaCl completely inhibited mycelial growth at concentrations of 100 ppm, 1.0 ppm, 0.4 ppm and 1.0%, respectively. The mycelium of MG-fungus was killed in 10 ppm cycloheximide solution and 2% NaCl within 24 hours and 0.5 ppm malachite green solution within 2 hours.
