ABSTRACT
El Staphylococcus lugdunensis se manifiesta más como Staphylococcus aureus que como un típico estafilococo coagulasa negativa, especialmente por su gran virulencia y capacidad para producir infecciones supuradas. Debido al protagonismo creciente de esta especie, es propósito de esta investigación destacar la significación clínica y los aspectos microbiológicos para el diagnóstico de pacientes con dicha infección.
The Staphylococcus lugdunensis is manifested more as Staphylococcus aureus that as a typical negative coagulase staphylococcus, especially for its great virulence and capacity to produce suppurated infections. Due to the growing protagonism of this species, this investigation aims at highlighting the clinical significance and microbiological aspects for the diagnosis of patients with this infection.

Abstract Staphylococcus lugdunensis is a rare virulent coagulase-negative staphylococcus (CoNS) that behaves similarly to Staphylococcus aureus in causing deep abscesses, skin and soft tissue infections, and central nervous system infections. Additionally, there can be certain blood stream infections including sepsis, septic shock, toxic shock syndrome, and endocarditis complicated by embolic events. Reports of septic arthritis of a native joint associated with this organism have been infrequent, justifying the presentation and discussion of this case.

Se presenta el caso clínico de un paciente de 53 años que tras una intervención neuroquirúrgica (laminectomía) presentó cuadro séptico. Se identificó la presencia de S. lugdunensis en la herida operatoria. El ecocardiograma transesofágico demostró rotura valvular mitral, vegetaciones e insuficiencia mitral masiva. El paciente se recuperó satisfactoriamente tras reemplazo valvular por prótesis mecánica.
A 53 year old man developed sepsis following laminectomy for spinal disease. S lugdunensis was identified from the surgical wound. Trans esophageal echocardiography demonstrated mitral valve rupture, vegetations and severe mitral regurgitation. The patient successfully recovered following mitral valve replacement with a mechanical prosthesis.
