The genus Pseudomonas was described in 1894 and is one of the most diverse and ubiquitous bacterial genera whose species have been isolated worldwide in all kinds of environments, from the Antarctica to the Tropics, present in sediments, clinical samples, plant, fungi and diseased animal specimens, water, soil, plant rhizosphere, sea, deserts, etc. The taxonomy of the genus has been controversial for years since a lot of bacterial taxa initially included in genus Pseudomonas have been reclassified in other genera or species from a different class of Proteobacteria over the years, as techniques for characterization and classification of microorganisms improved, aiming to set a phylogenetic classification of the species. In this review, the historical evolution of the taxonomy of Pseudomonas is described, and the currently valid criteria and future challenges for taxonomy of the genus and techniques used to achieve the necessary characterization for classifying the species are discussed. Finally, all the validly published Pseudomonas species at present are listed with an overview of their diversity and ecology.
假单胞菌属于 1894 年被描述，是最具多样性和普遍性的细菌属之一，其物种已在世界各地的各种环境中被分离出来，从南极洲到热带地区，存在于沉积物、临床样本、植物、真菌和患病动物标本、水、土壤、植物根际、海洋、沙漠等中。多年来，由于许多最初归入假单胞菌属的细菌分类群已被重新分类为其他属或来自不同类别的变形菌门的物种，因此该属的分类学一直存在争议，随着微生物特征描述和分类技术的提高，旨在建立物种的系统发育分类。在这篇综述中，描述了假单胞菌属的分类学的历史演变，并讨论了目前有效的分类标准和未来的挑战，以及用于实现对物种进行分类所需的特征描述的技术。最后，列出了目前所有有效发表的假单胞菌属物种，并概述了它们的多样性和生态学。
