MARTINEZ ORTIZ, Carlos M.; SAUTIE CASTELLANOS, Miguel; CUZA FERRER, Yordanka  e  WISDOM VINA, Yinette. Web Tool for classfication of polymorphic microsatellites in bacteria genomes. RCIM [online]. 2013, vol.5, n.1, pp. 20-29. ISSN 1684-1859.

The tandem repeat sequences, especially mini and microsatellites, have proven to be very effective in classification of pathogenic bacteria such as B. anthracis, M. tuberculosis and P. aeruginosa, among others. In human beings it is manifest its participation, being related with over eighty diseases, nearly all neurodegenerative and muscular, and some kinds of cancer. The web tool we are offering here is the result of computational detection of these sequences in whole bacteria genomes, and its respective annotation in the genomic structure according to the different regions where they are localized. The primary goal of this tool is to offer a relational system that allows mapping the microsatellites of bacterial species, all of them with more than one genome sequenced to infer their possible polymorphic character, in the context of genomic structure and thus providing a first approach to the putative role they perform from the functional point of view. The tool can be applied not only in taxonomical and epidemiological studies but in the detection of possible relationships of these sequences with the molecular functions, the biological processes and, as a last resort, the different forms of these species evolution. The web site offers the service of queries to the bacterial microsatellites database according to the related tables and its inherent attributes. It also has the typical services of this kind of site like: logging system, forum, polls, links and documentation about the employed methodology and the topic.
