Plain-English summary

A 9-year-old spayed female Great Dane developed an infection in her surgical wound on her left foot after having multiple skin lumps removed. The wound became swollen and started to discharge a foul-smelling pus. Tests showed that the infection was caused by a new type of bacteria that was resistant to multiple antibiotics, making it difficult to treat. The veterinary team worked to manage the infection, but the presence of this resistant bacteria highlighted the need for careful monitoring and treatment options for post-surgical infections in dogs.

Abstract

() is a β-hemolytic, Gram-positive novel bacterium first identified in 2006. It is a catalase-negative, non-motile coccus arranged in short chains. Furthermore, it has a broad beta-hemolytic reaction on sheep blood agar and cross-reacts with Lancefield group B antigen agglutination reagent. In this study, we report a case ofinfection of a surgical wound on the left metatarsus of a dog. The patient is a 9-year-old spayed female Great Dane dog with a brief history of multiple cutaneous masses being removed. Post-surgery, the post-surgical site on the left metatarsus became infected and discharged purulent material with a fetid odor. Upon preliminary diagnostic testing, we detected catalase-negative Gram-positive cocci exhibiting beta-hemolytic growth on sheep blood agar. A VITEK2 Compact machine from bioMérieux identified the bacterium as. Furthermore, antibiotic testing revealed multidrug resistance. Therefore, we document a multidrug-resistantisolate as a cause of canine post-surgical wound infection. Furthermore, it was the only isolate detected from the sample; hence, it is the cause of the infection. To our knowledge, this case is the first report ofin a dog.
