Plain-English summary
Two dogs with skin problems were found to have pustules caused by a type of bacteria called Staphylococcus coagulans, which is often linked to superficial bacterial folliculitis (SBF). In one dog, this bacteria was the only organism found in three pustules, while in the other dog, it was found alongside another bacteria called Staphylococcus pseudintermedius in some pustules. The study showed that the bacteria from the same pustules were genetically identical, suggesting they came from the same source. Understanding these bacteria can help veterinarians treat skin infections more effectively.

Abstract
BACKGROUND: Staphylococcus coagulans, formerly called Staphylococcus schleiferi subsp. coagulans is the second most common isolate from skin lesions of dogs with superficial bacterial folliculitis (SBF). However, the clinical significance of S. coagulans in pustules of canine SBF remains uncertain. This study aimed to investigate the prevalence and genotypic and phenotypic diversity of S. coagulans isolated from pustules in two dogs with SBF. RESULTS: Two dogs with SBF were included in this study. S. schleiferi/coagulans was isolated as the sole organism from three pustules in case #1, whereas it coexisted with S. pseudintermedius in two of seven pustules in case #2. S. pseudintermedius was the sole organism in the remaining five pustules in case #2. Whole genome sequences revealed that all isolates tested were annotated as S. coagulans. The isolates from the same pustules exhibited identical genotypic and phenotypic profiles, indicating clonal multiplication. S. coagulans isolated from different pustules exhibited similar yet distinct genotypic and phenotypic profiles. CONCLUSIONS: S. coagulans with identical genetic and phenotypic profiles can be identified as the sole pathogen or coexist with S. pseudintermedius in the pustules of the same dogs with SBF.
