Development of antitoxin with each of two complementary fragments of Clostridium botulinum type B derivative toxin.

abstract：:Since melanin is considered a virulence factor in Cryptococcus neoformans, its suppression at 37 degrees C has been perplexing. We now show an opposite thermal regulation of superoxide dismutase (SOD), consistent with a compensatory mechanism. Moreover, we demonstrate normal SOD and catalase levels in albino, oxygen-s...
