摘要

Cryptococcus neoformans is an opportunistic pathogen which attacks individuals with weakened immune systems. Two C. neo- formans isolates, 184A and NU-2, were examined to determine characteristics that contribute to their difference in virulence. Both isolates were grown under tissue culture conditions, and different characteristic were tested at timed intervals. Isolate 184A was found to grow at a faster rate than isolate NU-2, with doubling times of 4 an 12 hours respectively. The polysac- charide capsule of isolate NU-2 doubled in size in four hours, while that of isolate 184A stayed approximately the same.
