Recovery of a catalase-negative Staphylococcus epidermidis strain in blood and urine cultures from a patient with pyelonephritis

Abstract

This report describes a 60-year-old patient with bilateral nephrolithiasis. A catalase-negative Staphylococcus epidermidis strain was recovered from both urine and blood cultures. Although rare, isolates of catalase-negative Staphylococcus spp., including Staphylococcus aureus, have been reported. Here, we describe the first report of a catalase-negative S. epidermidis strain.
