Abstract |
Streptococcus uberis, the most frequent cause of mastitis in lactating cows, is considered non-pathogenic for humans. Only a few case reports have described human infections with this microorganism, which is notoriously difficult to identify. We report the case of a 75-year-old male haemodialysis patient, who developed a severe foot infection with osteomyelitis and bacteraemia. Both Streptococcus uberis and Staphylococcus aureus were identified in wound secretion and blood samples using mass spectrometry. The presence of Streptococcus uberis was confirmed by superoxide dismutase A sequencing. The patient recovered after amputation of the forefoot and antibiotic treatment with ampicillin/sulbactam. He had probably acquired the infection while walking barefoot on cattle pasture land. This is the first case report of a human infection with Streptococcus uberis with identification of the microorganism using modern molecular technology. We propose that Staphylococcus aureus co-infection was a prerequisite for deep wound and bloodstream infection with Streptococcus uberis. |
