Applications of Molecular Taxonomy

Molecular taxonomy enables the accurate identification of bacterial species and has broad applications across various fields.

The use of advanced molecular tools in the taxonomy of the genus Bacillus has made it possible to identify more than 80 species that share substantial morphological and biochemical similarities.

Precise identification of pathogenic and non-pathogenic strains of bacterial species is of great importance in clinical sciences. Advanced methods like multilocus sequence typing have helped distinguish E. coli O157:H7 - a pathogenic strain from a non-pathogenic strain, E. coli K-12.

In an interesting case, patients from a particular hospital undergoing coronary bypass surgery got infected by Gordonia bronchialis. DNA fingerprinting was used to trace the source of this infection to a nurse.

Methods like next-generation sequencing have helped identify an uncultivable species like Akkermansia muciniphila.

16s ribosomal DNA sequence data from more than 10,000 samples across various natural habitats are studied to understand the diversity patterns of bacterial communities.
