The effects that immigration might have on the epidemiology of tuberculosis (TB) in a low-incidence area of Italy was investigated by determining, in autochthonous and immigrant TB patients, the molecular characteristics of the Mycobacterium tuberculosis complex (MTBC) isolates, which may provide information on their phylogeographical origin. A total of(More)
Among the genotypes that prevail in the modern spectrum of Mycobacterium tuberculosis strains, the Beijing genotype is the one that causes major concern, as it is geographically widespread and it is considered hypervirulent. Comparative genomic studies have shown that Beijing strains have principally evolved through mechanisms of deletion of chromosomal(More)
BACKGROUND Recently our group has identified a novel antigen of Mycobacterium tuberculosis, protein PPE44, belonging to the "PPE protein" family. Although its role in infection is largely unknown, PPE44-specific immune responses were detected in mice infected with M. tuberculosis; moreover, immunization of mice with PPE44 subunit vaccines resulted in(More)
