Kingella kingae, a fastidious hemolytic gram-negative bacillus once considered to be an exceptional cause of disease, has emerged in recent years as an important invasive pathogen in children. When synovial fluid and other exudates were inoculated into blood culture bottles, enhanced recovery of the organism was observed, and an annual incidence of invasive K. kingae infections of 27.4 per 100,000 children younger than age 24 months was demonstrated in southern Israel. Skeletal infections are the most common clinical presentation of K. kingae, and studies conducted in that region have shown that this organism is the most common etiology of septic arthritis in children below the age of 24 months. Other invasive diseases caused by K. kingae include bacteremia, endocarditis, and infections involving the lower respiratory tract, the eyes, or the central nervous system. Recent studies have demonstrated that K. kingae is part of the normal oropharyngeal flora of young children. Clinical data suggest that the organism may gain access to the bloodstream in the course of an upper respiratory infection or stomatitis. The organism is susceptible to a wide range of antimicrobial drugs, and with the exception of some cases of endocarditis, K. kingae infections in children usually run a benign clinical course.

An exceptional case of microbiologically confirmed oral infection with Kingella kingae in an immunocompetent adult (30-year-old woman) is presented and the pathogenesis is discussed and related to known literature data.K. kingae is a rather common but yet relatively unknown commensal corroding bacterium from the oro- and nasopharynx in healthy children, which might turn into a human pathogen causing osteomyelitis, arthritis, spondylitis, endocarditis and intervertebral diskitis in young children and rarely endocarditis, septic arthritis, meningitis, epiglottitis, diskitis and bacteraemia in adults. Sofar K. kingae associated stomatitis was reported in children and a few adults, however, with concomitant herpes simplex virus infections, and without microbiological confirmation. In the described case no viral infection was found. The proven K. kingae stomatitis represents an extension of the pathogenic spectrum and suggests that the breach of the oral mucosal barrier can be caused by the bacterial pathogen itself. Whether a concomitant viral infection is necessary forK. kingae to actually invade the bloodstream remains to be considered.

In recent years, Kingella kingae has emerged as an important cause of invasive infections in young children, especially septic arthritis, osteomyelitis, spondylodiscitis, bacteraemia, and endocarditis, and less frequently lower respiratory tract infections and meningitis. The organism is part of the pharyngeal flora of young children and is transmitted from child-to-child. The clinical presentation of invasive K kingae disease is often subtle and laboratory tests are frequently normal. A substantial fraction of children with invasive K kingae infections have a recent history of stomatitis or symptoms of upper-respiratory-tract infection. The organism is susceptible to a wide array of antibiotics that are usually given empirically to young children including beta lactams, and with the exception of cases of endocarditis, the disease runs a benign clinical course. Although isolation and recognition of the organism is not difficult, clinicians and microbiologists should be aware of its fastidious nature. To optimise the recovery of K kingae, inoculation of synovial fluid specimens into blood culture vials is strongly recommended.
