Serratia

Belongs within: Enterobacterales. Serratia is a genus of rod-shaped, facultatively anaerobic bacteria, some species of which produce the red pigment prodigiosin (Ajithkumar et al. 2003).

Belongs within: Life.Contains: Spirochaetia, Planctobacteria, Bacteroidota, Deferribacteres, Aquificales, Campylobacteria, Acidobacteriota, Deltabacteria, Proteobacteria. The Spirochaetes are a distinctive group of helically coiled, motile bacteria. Some species are notorious pathogens such as Treponema pallidum (causing syphilis) and Borrelia burgdorferi (causing Lyme disease). Pathogenic species of Borrelia are commonly transmitted by bites from ticks. <==GracilicutesCD21 | i. s.:… Continue reading Gracilicutes

Rickettsiales

Belongs within: Proteobacteria. The Ricksettiales are a group of bacteria that are mostly obligately intracellular symbionts of eukaryotes. Members of the Anaplasmataceae lack cell walls and grow only in red blood cells (Prescott et al. 1996). Many Rickettsiales are pathogenic though others are more benign, and it is believed that the ancestors of eukaryotic mitochondria… Continue reading Rickettsiales

Deferribacteres

Belongs within: Gracilicutes. The philosopher’s bacterium Published 26 September 2013 Picture the mediaeval alchemist, standing before a smoking crucible, adding ingredients and performing the requisite incantations. Eventually, he allows the crucible to cool so that he might examine the results. Has he succeeded? Has he achieved his goal of extracting pure gold from the base… Continue reading Deferribacteres

Aeromonas

Belongs within: Chromatibacteria. Pathogens, or more than pathogens? Published 17 March 2009 Aeromonas is a genus of rod-shaped facultatively anaerobic gamma proteobacteria that is abundant in aquatic habitats (mostly freshwater). 16S rDNA phylogenetically speaking, it belongs to a clade that also includes the Vibrionaceae, Pasteurellaceae and Enterobacteriaceae, all of them pretty economically significant families because… Continue reading Aeromonas

Campylobacteria

Belongs within: Gracilicutes. Epsilon of the deeps: coming soon to an organ system near you Published 2 June 2008 The can be no denying that the direct analysis of DNA sequence data sparked a revolution in bacterial systematics. Previously-recognised taxa were reinforced or struck down, while entirely new groups were raised to recognition. The Proteobacteria… Continue reading Campylobacteria

Aquificales

Belongs within: Gracilicutes. Standing the heat Published 26 March 2008 The Aquificae are a smallish group of thermophilic to hyperthermophilic bacteria whose main claim to fame is that ribosomal DNA phylogenies suggest that it is the earliest-diverging branch of the Eubacteria, making them a key player in the theory that life as a whole may… Continue reading Aquificales
