Jari Intra, Cecilia Sarto, Massimo Andreotti, Achille Marino, Tiziana Varisco, Paolo Brambilla


Bacillus pumilus is commonly isolated from a wide variety of soils, plants and environmental surfaces, but rarely from human specimens. In this report, we describe a case of infection caused by B. pumilus in a healthy 10-years-old child. The microorganism was recovered from a severe wound of the left knee after three days from trauma. Pathogen identification was carried out by mass spectrometry. The patient's outcome was positive following an ampicillin/sulbactam treatment without complications.
