Abstract

is still a rare cause of infection. We present a case of an immunocompetent patient admited in the hospital with functional impotence, pain and erythema in his left leg after suffering two scratches from his cat 48 h ago. After obtaining blood and wound cultures, broad-spectrum antimicrobial therapy with intravenous amoxicillin clavulanate was initiated. After 1 day and with a clear improvement of the symptoms the patient was discharged from the hospital with cellulitis and transient bacteremia as diagnosis and completing 1 week of antimicrobial therapy orally. After 80 and 92 h of incubation, both anaerobic flasks were positive. In the Gram-stain Gram-negative rod-shaped bacteria could be observed. Despite subculturing in brucella blood agar, tripticase soy agar with 5 % of sheep blood and chocolate agar, in both anaerobic and microaerophilic conditions, the strain could not be recovered. However, these Gram-negative rods could be identified as by 16S rRNA sequencing, Capsular typing was performed to study the strain, but none of the studied capsule-types tested positive. is still a rare cause of human infection, but it must be considered in the differential diagnosis of infections related to bites, scratches and licks from dogs or cats.
