Abstract:We describe a case of erysipelas in a free-ranging endangered Hawaiian crow. The partially scavenged carcass exhibited gross emaciation and petechial hemorrhages in both lungs. Microscopy revealed multiple necrotic foci associated with gram-positive rods in the liver and adrenal, diffuse acute proximal tubular necrosis of kidney, diffuse necrosis and inflammation of proventricular mucosa associated with gram-positive rods, and multiple intravascular aggregates of gram-positive rods associated with thrombi. Culture of the kidney revealed the bacterium to be Erysipelothrix rhusiopathiae. The implications of this finding to free-ranging crows remain unclear. /// Se describe un caso de erisipelas en cíervos Hawaianos silvestres en peligro de extinción. Los cadáveres parcialmente consumidos por aves de rapiña mostraron emaciación y hemorragias petequiales en ambos pulmones. El examen microscópico reveló múltiples focos necróticos asociados con bacilos gram positivos en el hígado y glándulas adrenales, necrosis tubular proximal difusa en el riñón e inflamación de la mucosa del proventrículo asociada con bacilos gram positivos y agregados intravasculares múltiples de bacilos gram positivos asociados con trombos. El cultivo de los riñones reveló que la identidad de la bacteria era Erysipelothrix rhusíopathiae. Las implicaciones de estos hallazgos en ciervos Hawaíanos silvestres no son muy claras todavía.
