A 65-year-old male is admitted to the hospital with high fever, shaking chills, nausea, and vomiting. His medical record indicates that he has a history of emphysema and has been a heavy cigarette smoker since he was a teenager. A complete blood cell count, differential, and chemistry profile are ordered by the physician. The CBC reveals a WBC count of 15,000/uL with 40% bands, 46% segmented neutrophils, 11% lymphocytes, and 3% monocytes. Breathing was labored, and chest x-ray film revealed consolidation of the upper part of the lung. Sputum and blood cultures were performed. Examination of the plates at 24 hours of incubation reveals heavy growth of a mucoid lactose fermenter on MacConkey plate. A few alpha-hemolytic colonies are observed on the CNA plate. The statement that most likely describes these observations is:

A) The colonies on MacConkey should be considered to be pathogenic and those on CNA normal flora.
B) The colonies on CNA should be considered pathogenic and those on the MacConkey normal flora.
C) The colonies on MacConkey and CNA are both normal flora.
D) The colonies on MacConkey and CNA are both pathogens.
