Enhanced patient serum immunoreactivity to recombinant Mycobacterium tuberculosis CFP32 produced in the yeast Pichia pastoris compared to Escherichia coli and its potential for serodiagnosis of tuberculosis.


CFP32 is a Mycobacterium tuberculosis complex-restricted secreted protein that was previously reported to be present in a majority of sputum samples from patients with active tuberculosis (TB) and to stimulate serum antibody production.
