Genomics of clostridial pathogens: implication of extrachromosomal elements in pathogenicity.

abstract：:Activation of professional phagocytes with the concomitant generation of oxidant species is a medullar innate immune process for the control of acute Trypanosoma cruzi infection. Recent data reinforce the hypothesis that parasites more prepared to deal with the host-oxidative assault are more efficient for the establi...
