Document Summary

What is the unit of classification: the species is important. It usually represents the basic unit of classification: smallest grouping used in classification, the concept of bacterial species is not well defined. *phyloge(cid:374)y (cid:271)asi(cid:272)ally studies the (cid:862)history(cid:863), evolutio(cid:374), the related(cid:374)ess of orga(cid:374)is(cid:373)s. Usually is the first cell discovered, isolated, described from that species and used to compare: type strain: refers to strain selected as the reference strain for the species. It is usually the first strain isolated and described that represents the species: the type strain is very important and is maintained in a viable state in various collection centers dsm, atcc, etc. Hierarchical ranking: what is that: most classifications employ some form of hierarchical ranking, on the basis of shared characteristics organisms are placed into successively larger groups, taxa of higher rank. In taxonomy, species is the smallest grouping and has the lowest rank.
