Thigh abscess caused by Eikenella corrodens and Streptococcus intermedius: A case report

Subcutaneous Eikenella corrodens, Actinomyces sp., and α-Hemolytic Streptococcus Abscess of the Thigh following a Vitamin B12 Injection

“…When E. corrodens causes an infection, it is usually a polymicrobial infection and very often associated with Streptococcus organisms (as seen in our case) at rates of up to 50% of these infections in children and approximately 70% in adults [ 7 , 8 ]. As in our case, E. corrodens infections associated with Actinomyces have been reported [ 9 – 11 ].…”

“…The development of limb abscesses caused by E. corrodens that requires both surgical and antibiotic treatment is rare. For example, Zhiyong et al [ 8 ] reported a case of a 35-year-old Chinese female patient who was described as healthy and developed a thigh abscess from which E. corrodens and S. intermedius were grown.

“…Eikenella corrodens is a fastidious, facultative, anaerobic Gram-negative bacilli, which normally colonizes the mouth, upper respiratory tract, and other mucosal surfaces in humans. 19 It is part of the HACEK group of organisms (Haemophilus aphrophilus, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae), which are part of the normal oropharyngeal flora in humans and are an important cause of infective endocarditis, bacteremias, and assorted abscesses. Oftentimes, Eikenella infections are polymicrobial involving human bite wounds, periodontal and head and neck infections.…”
