Staphylococcus caledonicus sp. nov. and Staphylococcus canis sp. nov. isolated from healthy domestic dogs

Two strains, H8/1Tand H16/1AT, of Gram-stain-positive, coagulase-negative staphylococci were isolated from separate healthy domestic dogs in Scotland. Both strains were genome sequenced and their inferred DNA–DNA hybridisation indicates that H8/1Tand H16/1ATrepresent two novel species of the genusStaphylococcus. On the basis of the results of genome sequence analysis (genomeblastdistance phylogeny and single nucleotide polymorphism analysis) H8/1Tis most closely related toStaphylococcus devrieseiand H16/1ATmost closely related toStaphylococcus felis. Also, average nucleotide identity distinguished H8/1Tand H16/1ATfromS. devrieseiandS. felisas did minor phenotypic differences. On the basis of these results, it is proposed that H8/1Tand H16/1ATrepresent novel species with the respective namesStaphylococcus caledonicusandStaphylococcus canis. The type strain ofS. caledonicusis H8/1T(=NCTC 14452T=CCUG 74789T). The type strain ofS. canisis H16/1AT(=NCTC 14451T=CCUG 74790T)
