It presents informations about the Institution, programs and projects.techniques of molecular biology to study pathogenic organisms. In conjunction with public health investigators. Use molecular biology to create DNA fingerprints of bacteria, to better track the spread of organisms within the community. This combination is known as molecular epidemiology.This study the genetic differences between closely related organisms in order to understand the reason why some cause disease and others are less virulent. employ a variety of genetic techniques, including PCR, DNA sequencing, subtractive hybridization and DNA microarrays to understand the molecular differences within the M. tuberculosis complex and within the M. avium complex.
