INOCULUM PREPARATION FOR IN-VITRO SUSCEPTIBILITY TESTING OF FILAMENTOUS FUNGI

The percent transmission (T) and the equivalence in cfu/mL of two susp ensions of 125 isolates of clinically important filamentous fungi cont aining 1-5 x 10(5) and 1-5 x 10(4) conidia/mL, adjusted with a haemocy tometer, were determined. A wide variation of T values was observed, e specially with the first inoculum, A good agreement was obtained betwe en the counted and the viable propagules, The haemocytometric method i s considered a useful technique for standardizing inocula.
