Today we have many interesting articles,  Marangoni A. evaluates  antifungal properties of Spirulina platensis against  Candida species; J. de Gunzburg  reports on gut microbiome  protection from antibiotics; E. Uhlig writes about removal of Escherichia coli from “ready‐to‐eat” salads .. while in my personal non microbiological pics you can read the study from A.Carter about women’s visibility in academic seminars. Apparently women ask fewer questions than men. Enjoy your winter read.
