These bacteria are Aggregatibacterium actinomycetemcomitans, Eikenella corrodens
OBJECTIVES: Define the term osteomyelitis and describe the pathogenesis of this condition; identify the common bacterial causes of osteomyelitis; explain the etiologic nature of the organism, Eikenella corrodens
, and its uniqueness to this case.
, a common pathogen found in bite wounds, was present in a swab of the patient's wound.
Most microorganisms involved in these disease are gram-negative bacilli, anaerobes (Porphyromonas gingivalis, Prevotella intermedia, Fusobacterium nucleatum, Campylobacter rectus) or capnophiles (Aggregatibacterium actinomycetemcomitans, Eikenella corrodens
, Capnocytophaga ochracea .
Actinomyces viscosus, Porphyromonas gingivalis, Campylobacter rectus, Streptococcus sanguis, Eikenella corrodens
, Salmonella typhimurium, Fusobacterium nucleatum, Haemophilus actinomycetemcomitans, Lactobacillus casei, and P intermedia (78)
Although rare, infective endocarditis is caused by gram-negative organisms such as the HACEK (Haemophilus aphrophilus, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens
, Kingella kingae) group, Bartonella spp.
It is most commonly associated with a group of gram-negative bacilli collectively known as HACEK (for Hemophilus parainfluenzae, H aphrophilus, Hemophilus paraphrophilus, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens
, and Kingella kingae).
