[Kingella kingae infections in the pediatric age].

Kingella kingae infections have aroused great interest in the last few years because of the increasing number of identified cases. Although considered an emerging pathogen, the increase in diagnosis of these infections can probably be explained by better knowledge of the bacteria, improved microbiological diagnostic techniques and greater awareness among clinicians. K. kingae is an aerobic cocobacillus with high tropism for osteoarticular tissue, endocardium, and vascular space. This pathogen mainly produces osteomyelitis, endocarditis, septic arthritis and bacteriemias. First choice antibiotics are penicillins and cephalosporins. This article reviews the literature on this microorganism.
