A1 TAIT, LARRY R.YR 1978 T1 Cytophaga aquatilis sp. nov., a Facultative Anaerobe Isolated from the Gills of Freshwater Fish JF International Journal of Systematic and Evolutionary Microbiology, VO 28 IS 2 SP 293 OP 303 DO https://doi.org/10.1099/00207713-28-2-293 PB Microbiology Society, SN 1466-5034, AB A facultatively anaerobic, gram-negative, gliding bacterium was isolated from the gills of freshwater fish. Its deoxyribonucleic acid base composition (33.7 mol% guanine plus cytosine), lack of microcysts or fruiting bodies, cell size (0.5 by 8.0 μm), and hydrolysis of carboxymethylcellulose and chitin place it in the genus Cytophaga. This aquatic cytophaga is differentiated from other cytophagas by its fermentation of carbohydrates, proteolytic capabilities, and a number of additional physiological and biochemical tests. The organism was compared to other similar isolates reported from fish, and it appears to belong to a new species, for which the name Cytophaga aquatilis is proposed. The type strain of C. aquatilis, N, has been deposited with the American Type Culture Collection under the accession number 29551., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-28-2-293
