Plain-English summary

A Poodle dog was diagnosed with a serious infection that caused nodules in its lungs and bone lesions. The infection was caused by a type of bacteria that is not commonly reported in dogs. After testing, the vet started the dog on a four-month course of amoxicillin-clavulanate, which successfully resolved the symptoms. However, the vet advised that longer treatment might be necessary to prevent future infections, as the bacteria can return.

Abstract

Paenibacilli are gram-variable, endospore-forming bacteria that occupy various ecologic niches. These microorganisms have been known to infect humans occasionally at various anatomic sites. However, in humans, as well as in other vertebrate animals, the relationship between disease and isolation ofspp. remains poorly understood. We report here a case of infection in an adult Poodle dog. The animal had nodules in the lungs and multifocal osteolytic expansile bone lesions. From bone,was recovered by culture and identified by MALDI-TOF mass spectroscopy and 16S rDNA sequencing; pyogranulomatous inflammation was observed in lung and bone specimens. The microorganism was resistant to clindamycin and imipenem. Four-month treatment with amoxicillin-clavulanate resulted in clinical resolution of disease in this dog. Nevertheless, therapy for more prolonged periods should be considered because recurrent infections can occur as a result of the transition ofspores to vegetative cells. Disease caused by aspecies has not been reported previously in dogs, to our knowledge.
