Objective:
To explore the possible relationship between the -2518 A/G single nucleotide polymorphisms in monocyte chemoattractant protein-1 (MCP-1) gene of Chinese Han population and the susceptibility to pulmonary tuberculosis.
Methods:
A 1:1 matched case-control study was conducted from March 2008 to August 2008. The - 2518 MCP-1 A/G polymorphisms were detected in 167 pairs of subjects by reaction-restriction fragment length polymorphism (PCR-RLFP) technique. General characteristics, current disease history, past medical history and related environmental factors of tuberculosis were collected using a questionnaire designed by ourselves. Univariate analyses and multivariate conditional logistic analyses were conducted.
Results:
The genotype frequencies of AA, GA and GG in the case group and the control group were 21/167 (12.6%), 62/167 (37.1%), 84/167 (50.3%) and 42/167 (25.2%), 83/167 (49.7%), 42/167 (25.1%), respectively. There was a significant difference in genotype frequencies between the case and the control groups in the univariate analysis (chi2 = 24.041, P<0.01). The significant association remained after adjusting environmental factors between genotype GG (OR 1.989, 95% CI 1.154 - 3.428, chi2 = 6.124, P<0.05) and the susceptibility to pulmonary tuberculosis.
Conclusion:
The -2518 MCP-1 GG genotype might be associated with susceptibility to pulmonary tuberculosis in Chinese Han population.

Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis I
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.
