Original publication title: Antibacterial Activity of Clove Essential Oil () Against Oxacillin-ResistantIsolated from Dogs with Otitis Externa.

Plain-English summary
A group of dogs with ear infections (otitis externa) caused by antibiotic-resistant bacteria was studied to see if clove essential oil could help. The researchers found that 34% of the bacteria from these dogs were resistant to common antibiotics. Clove oil showed promise, effectively inhibiting the growth of both resistant and non-resistant bacteria at a concentration of about 6.4 mg/mL. This suggests that clove essential oil could be a potential alternative treatment for ear infections in dogs, especially when traditional antibiotics fail.

Abstract
Infections caused by oxacillin-resistantare increasingly common in veterinary medicine. The indiscriminate use of antibiotics by pet owners worsens this problem, reducing treatment efficacy and creating the need for alternative therapies. This study aimed to evaluate the inhibitory effect of clove essential oil () on both oxacillin-resistant and susceptible. Thirty-five isolates from dogs with otitis externa were analyzed. The bacteria were identified by phenotypic tests and tested for susceptibility to 22 antibiotics using disk diffusion. Resistance genes (and) were detected using conventional PCR. Among the isolates, 34.28% (12/35) were positive for, and 97.14% (34/35) for. The essential oil's efficacy was assessed using broth microdilution to determine its minimum inhibitory concentration (MIC). Clove oil showed an average MIC and minimum bactericidal concentration (MBC) of 6.4 mg/mL, inhibiting both resistant and susceptible isolates. In conclusion, clove essential oil demonstrated in vitro antimicrobial activity against.
