SINGLE NUCLEOTIDE POLYMORPHISM OF ECCB5 GENE OF MYCOBACTERIUM TUBERCULOSIS COMPLEX ISOLATES FROM SUSPECTED PULMONARY TB PATIENTS IN SURABAYA INDONESIA

Mycobacterium tuberculosis Complex (MTBC) is a group of Mycobacterium that causes tuberculosis (TB). TB is an infectious disease that remains a global health problem. Indonesia is one of the five countries in the world where TB is the most prevalent and became the country with tle second largest rate of TB in 2014 and 2015. MTBC has high pathogenicity that can cause infections in animals and humans. The most common route of transmission is via airborne droplet nuclei and contact with animals or humans infected with TB. MTBC has many virulence factors. One of these factors is EccB5 that is encoded by eccB5 gene. EccB5 is a transmembrane protein-conserved membrane protein and could play a role in inducing damage in host cells, macrophage infection, and may correlate with active disease. The characterization of eccB5 gene needs to be studied to determine the nucleotide sequences, which may be associated with active disease. The aim of this research was to analyze the nuclotide sequences of eccB5 gene of MTBC from suspected pulmonary tuberculosis patients, SNPs of eccB5 gene and possible correlation with the disease, especially in Indonesia
