Thanks, Mary. I'll look in Riordan. Colleen, I'm sorry but I don't have any more info about this case as I was not involved. The question was asked by my colleague, a Neonatologist, for his wife, who is an IBCLC at another hospital. He is well aware of the difficulty in getting a "clean" specimen, the probability of growing many organisms, and the likelihood that if there actually was an organism to be concerned about that it might not even grow due to the WBCs and macrophages in human milk. He said he learned this first hand by ordering cultures very early in his career when they routinely cultured all milk in the NICU. Does anyone know of any studies that his wife can give to the client to give to the client's doctor that I can access easily for him?
