Case Study 7 - Identify the Cause?

June 26, 20102comments



A 35 year old male was admitted to a hospital with fever, chills and generalised body pain. The patient had received multiple courses of antibiotics prescribed by private practitioners before diagnosis. Serum of the patient was tested positive for HIV by ELISA and his CD4 cell count was 800 cells/μL. His blood culture showed growth with Gram positive cocci. Upon subulture on MacConkey agar, pin pointed pink colour colonies were observed. The isolate was found to be PYRase positive, CAMP test negative and resistant to Bacitracin, Penicillin and Vancomycin.

Proceed and identify the microorganism?
