Whatever their reasons, it was done very quietly – I only became aware of it in 2011 when one of my readers notified me. This is why you cannot rely on probiotic manufacturers to have your best interests at heart – and why I wrote this blog post on how to choose a potent probiotic.

I am bringing this up again because I recently came across this report/study of a 73-year-old male with chronic lymphocytic leukemia who had been previously taking Enterogermina brand probiotic (B. subtilis) as a means to manage his diarrhea. He was admitted to the hospital because of high fever, mental confusion, and persistent diarrhea. They ceased ingestion of Enterogermina upon his admittance. After further testing, a chest x-ray, and some blood cultures were performed, the man tested positive fo
