Purpose:
To investigate the usefulness of measuring C-reactive protein in the diagnosis of lung tuberculosis.
Object:
Tuberculosis patients treated by chemotherapy at Fukujuji Hospital from Jan./1/2000 to Dec./31/2001.
Method:
Chart review.
Results:
CRP are negative in 13.3% (95%CI: 8.9-17.7%) in sputum smear positive lung tuberculosis patients (N = 226), and in 73.0% (95%CI: 62.0-84.0%) of sputum smear negative culture positive lung tuberculosis patients (N = 63).
Conclusion:
Usefulness of measuring C-reactive protein in the diagnosis of bacteriological positive lung tuberculosis is limited.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
