Abstract

This case report examines a multidrug-resistant Staphylococcus pyoderma infection in a companion Rattus norvegicus. The clinical presentation involved a range of symptoms, including pruritus, inflammation, pustules, and crusts on the skin, indicative of bacterial pyoderma. Conventional and molecular techniques were used and the pathogen was identified as Staphylococcus chromogenes. The suspected transmission route was through a bite from another rat, although the aggressor was not tested. Initial treatment with enrofloxacin proved ineffective. Subsequently, an amoxicillin + potassium clavulanate treatment resulted in temporary improvement. However, a relapse occurred after 30 days, requiring a repetition of the treatment. The findings underscore the importance of accurate diagnosis, appropriate testing, and adherence to prescribed treatments for bacterial infections. The zoonotic potential of multidrug-resistant Staphylococcus highlights the need for better education of pet owners on transmission risks and treatment compliance. Further research is needed to investigate the transmission routes of this infection, potential risks to pet owners, and a more comprehensive understanding of Staphylococcus sp. pyoderma in pet rodents.
