Abstract

Two isolates of a Gram-negative, non-spore-forming coccobacillus cultured from the blood and cerebrospinal fluid of immunocompromised patients in the United States were described previously. Biochemical and phylogenetic analyses revealed that they belong to a novel species within the genus. Here we describe a third isolate of this species, recovered from blood of a febrile patient with renal failure, and formally name the species. Whole genome comparisons indicated the three isolates display greater than 99.9 % average nucleotide identity (ANI) to each other and are most closely related to the tick endosymbiont , with only 88.6–88.8 % ANI to the type strain of . Based on biochemical, metabolic and genomic comparisons, we propose that these three isolates should be recognized as sp. nov, with the type strain of the species, PA05-1188, available through the Deutsche Sammlung von Mikroorganismen und Zellkulturen (DSM 107100) and the American Type Culture Collection (ATCC BAA-2974).
