Abstract:

Necrotizing fasciitis (NF) is a potential life-threatening bacterial infection spreading into subcutaneous and fascial tissues rapidly. Several different bacteria involve in the etiology of the disease. In this report, a case has been presented with a probable diagnosis of necrotizing fasciitis from a two-year-old female tabby cat weighing 3 kilograms which is admitted to a veterinary clinic with the complaint of fascial wound. The cat was brought to Harran University Faculty of Veterinary Medicine Microbiology department because she has necrotic lesions without pus in her two sides of face. General condition of cat was evaluated as normal. Swabs taken from lesions were cultured on blood agar. After incubaton period, isolated bacteria were identified as Staphylococcus spp. and Streptococcus spp. by classical biochemical tests and as Staphylococcus felis ve Streptococcus canis, which are also zoonotic agents, by MALDI-TOF (Bruker Corporation Billerica, MA, USA). According to Kirby-Bauer disk diffusion antibiotic sensitivity test results, Staphylococcus felis was found to be sensitive to tetracycline, penicillin, enrofloxacin, ampicillin, gentamicin, erythromycin, vancomycin, novobiocin, amoxicillin/clavulanic acid and imipenem, mildly resistant to neomycin and streptomycin, and resistant to oxacillin. Streptococcus canis was found to be sensitive to penicillin, oxacillin, enrofloxacin, ampicillin, erythromycin, vancomycin, amoxicillin/clavulanic acid, and imipenem, mildly resistant to neomycin, tetracycline, and novobiocin, and resistant to streptomycin and gentamicin. According to these results, a treatment regimen involving enrofloxacin and amoxicillin / clavulanic acid combination was given for 10 days. Treatment was also supported by the oil of centaury, aloe vera gel, and propolis for two weeks. At the end of treatment, clinical improvement was observed. As conclusion, it was thought that an effective treatment should include the determination of the etiological agents of NC and to use effective antibiotics to these agents for both animal and human health.
