During the analysis of a collection of Pseudomonas strains linked to an outbreak in an intensive care unit at King Faisal Specialist Hospital and Research Center in 2019, one isolate (CFS3442 T ) was identified phenotypically as Pseudomonas aeruginosa . However, whole-genome sequencing revealed its true identity as a member of the genus Stenotrophomonas , distinct from both P. aeruginosa and Stenotrophomonas maltophilia . The isolate demonstrated: (i) a significant phylogenetic distance from P. aeruginosa ; (ii) considerable genomic differences from several S. maltophilia reference strains and other Stenotrophomonas species; and (iii) unique phenotypic characteristics. Based on the combined geno- and phenotypic data, we propose that this isolate represents a novel species within the genus Stenotrophomonas , for which the name Stenotrophomonas riyadhensis sp. nov. is proposed. The type strain is CFS3442 T (=NCTC 14921 T =LMG 33162 T ). |
