MAC-SSR Database

Welcome on our INMV's classification database: “MAC-INMV”
dedicated to typing of Mycobacterium avium subsp. paratuberculosis, hominissuis, avium and silvaticum

map Genotyping applied to strains of Mycobacterium avium subsp. paratuberculosis (MAP) becomes an indispensable tool for epidemiological surveillance of this significant veterinary pathogen. For MAP, multi-locus variable number tandem repeat analysis (MLVA) targeting mycobacterial interspersed repetitive units (MIRUs) and other variable-number tandem repeats (VNTRs) was established using 8 markers. This standard, portable, reproducible and discriminatory typing method has the potential to be a versatile tool for the strain identification of MAP and also member of Mycobacterium avium complex MAC. Within the past 5 years a number of genotypes (termed INVM) of strains of diverse origins have been identified in our laboratory and by other, however, no web tools was available for knowing the already existing INMV profiles and storing newly defined genotypes.
To meet this need a web application called “Mac INMV database” monkly was developed. This freely accessible service allows users to compare the genotyping data of their strains analysed by MLVA with those of existing reference strains.

A freely accessible database was created with genotyping data of strains of MAP and of other MAC members. This database gathers all INMV profiles obtained in the laboratory and those published in the literature.
  • The database information include incrementing species and subspecies status, INMV profiles with corresponding alleles/repeat numbers at each locus, and combined numerical genotypes.
  • The user can consult and query all the existing INMV profiles in order to see if profiles identified in his lab already exist. If profiles are not known, the user can request new attribution numbers online.
  • All information can be exported under EXCEL or PDF format. An extensive documentation regarding the genotyping method, protocols, primer sequences, marker information, is available to the users.
Users are invited to provide any comments, always welcome, to improve this database
