Abstract Wautersiella Falsenii is an unusual organism isolated from human samples. Its clinical relevance needs to be defined. Solitary identification of this microorganism in a clinical sample explains an etiological link between it and the disease. We present such a case that came to us with respiratory distress and later on diagnosed to have pneumonia, mediastinal abscess and bacteremia. Aetiological work up isolated Wautersiella Falsenii from the blood which was sensitive to ofloxacin. No any other organism was isolated. The patient responded well to the ofloxacin treatment and was discharged in good general condition. Solitary identification and clinical improvement on effective antibiotic; supports that it is a clinically significant infection. In this case report we discuss the clinical spectrum of diseases caused by this organism and its antibiotic sensitivity pattern.
