Pseudochrobactrum algeriensis sp. nov., isolated from lymph nodes of Algerian cattle

Abstract

Three Gram-negative, rod-shaped, oxidase-positive, non-spore-forming, non-motile strains (C130915_07T, C150915_16 and C150915_17) were isolated from lymph nodes of Algerian cows. On the basis of 16S rRNA gene and whole genome similarities, the isolates were almost identical and clearly grouped in the genus Pseudochrobactrum . This allocation was confirmed by the analysis of fatty acids (C19:cyclo, C18 : 1, C18 : 0, C16 : 1 and C16 : 0) and of polar lipids (major components: phosphatidylethanolamine, ornithine-lipids, phosphatidylglycerol, cardiolipin and phosphatidylcholine, plus moderate amounts of phosphatidylmonomethylethanolamine, phosphatidyldimethylethanolamine and other aminolipids). Genomic, physiological and biochemical data differentiated these isolates from previously described Pseudochrobactrum species in DNA relatedness, carbon assimilation pattern and growth temperature range. Thus, these organisms represent a novel species of the genus Pseudochrobactrum , for which the name Pseudochrobactrum algeriensis sp. nov. is proposed (type strain C130915_07T=CECT30232T=LMG 32378T).

Diversidade taxonômica e funcional da microbiota de fezes de macacos bugios (Alouatta spp.) de cativeiro e vida livre

“…Pseudochrobactrum, sendo a primeira cepa proveniente de fezes de mamífero. Este gênero, descrito pela primeira vez em 2006 é composto por 6 espécies: P. saccharolyticum, P. assaccharolyticum, P. kiredjianiae, P. glaciei, P. lubriicis e P. algeriensis (Kämpfer et al, 2006;Kämpfer et al, 2007;Romanenko et al, 2008;IJSEM, 2009;Kämpfer et al, 2009;Loperena-Barber et al, 2022).todas provenientes de amostras ambientais, com exceção do isolado de P. algeriensis que foi isolado de linfonodo de gado argelino.…”
