A patient who was recently diagnosed with an obstructed bowel became septic from Proteus vulgaris. Prior to surgery, a routine type and screen was performed. Though this person typed as an A two years ago, his forward type is consistent with an AB individual, albeit weaker in strength with anti-B. What is the reason for this discrepancy?
