[Bacteraemia due to Eikenella corrodens secondary to periodontal infection in a neutropenic patient].

We present the case of a 44 year-old patient, without significant previous medical history, who presented a systemic infection due to Eikenella corrodens following a dental extraction in the context of an agranulocytosis of pharmacological origin due to carbimazole. During admission he was treated with broad-spectrum antibiotics and G-CSF 5 μg/kg/day, undergoing a favorable evolution and receiving hospital discharge on the seventh day. Invasive infections due to Eikenella corrodens that develop bacteriaemia are less than 20%, and are generally secondary to the drainage of previous abscesses and are usually isolated together with other microorganisms; while finding a monomicrobial primary bacteriaemia without the prior existence of endocarditis is exceptional. This is the first case of systemic infection due to this bacteria secondary to dental manipulation, where the state of transitory immunosuppression in which the patient found himself at that time was determinant in causing the disseminated infection.
