ABSTRACT

Introduction: Coagulase negative Staphylococci (CoNS) are frequently isolated from blood cultures. New members of this cluster are consistently added to the catalogue of human pathogens. Staphylococcus cohnii is one of the rarer agents of bacteraemia. This is the first case report of bacteraemia by Staphylococcus cohnii subsp. urealyticus from India. Case report: A 63 year old female diabetic patient was admitted to the hospital with pyrexia and pressure ulcer on the left leg. Initial workups did not divulge any focus of infection. After 4 days of admission, the blood culture was positive and Staphylococcus cohnii subsp. urealyticus was isolated. The organism was susceptible to most antibiotics and the patient convalesced. Discussion: Staphylococcus cohnii is reported sporadically all over the world as an agent of blood stream infection. Development of resistance to antimicrobials, including linezolid has been reported. Such cases must be presented frequently to underscore the enormity of CoNS as pathogens to thwart their refutation as mere contaminants.
