SITVIT WEB, online consultation of the WorldWide database of M. tuberculosis.
SITVIT is a Mycobacterium tuberculosis molecular markers database. It contains three major types of molecular markers: Spoligotypes, MIRU and VNTR markers. Spoligotypes are patterns formed by the presence or absence of 43 spacers in the DR locus of Mycobacterium tuberculosis. This pattern can be seen as a 43 digit pattern or under a reduced octal form of only 15 numbers. MIRU markers (Mycobacterial interspersed repetitive units) are variable number of tandem repeats markers. The MIRU method currently used on Mycobacterium tuberculosis is composed of 12 different MIRU loci. A mirutype is a 12 digits pattern representing the number of repetitions of each of these 12 specific loci. But Mycobacteria genome counts also several short nucleotide sequence organism as tadem repeat named Variable Number Tandem Repeats (VNTR). Five exact tandem repeat (ETR) are used for VNTR analysis of M. tuberculosis complex. This is the third marker contained in our database. Each ETR locus contains multiple tandem copies of a particular repeat unit, association of all of them generates alleles profile useful for the identification and the evolutionary studies of M tuberculosis complex.
