Taxonomic
Definition:
(a.) Pertaining to, or involving, taxonomy, or the laws and principles of classification; classificatory.
Example Sentences:

(2) Bordetella pertussis and Bacillus anthracis, two taxonomically distinct bacteria, secrete adenylate cyclase toxins that are activated by the eukaryotic protein calmodulin.
(3) The present classification of vasculitis has several objections, based on the following aspects: 1) It does not take into account taxonomic rules; 2) It uses criteria which helps to cover up; 3) It uses generic terms without a specific meaning; 4) Lack of clinical interest.
(4) As an extension to the variety of existing techniques using polymorphic DNA markers, the Random Amplified Polymorphic DNA (RAPD) technique may be used in molecular ecology to determine taxonomic identity, assess kinship relationships, analyse mixed genome samples, and create specific probes.
(5) Authors pointed on etiologic connections between particular clinical syndroms in AIDS and microbial, parasitic and viral agents belonging to different taxonomic groups.
