Since first described by Woodward and Clark in 1913,1 sporadic case reports of human infection by Serratia marcescens have been recorded. In the early literature, reports were limited mainly to persons suffering from chronic debilitating or complicated disease processes. These were usually pulmonary infections, sometimes demonstrating the symptom of "pseudohemoptysis," or urinary tract infections occurring after instrumentation of the lower urinary tract.2-5 Recent reports, however, have revealed that this organism will appear as a "super infection" after intensive antibiotic therapy.6,7 Such case reports point up the dangers of a secondary infection by these gram-negative motile rods, which closely resemble enterococci both in culture characteristics and in their resistance to most of the currently used antibiotics.8,9
