Harmful genetic mutations may be less common than thought
New research suggests point mutations in bacteria arise at a relatively low, constant, rate and only 1% of these changes are lethal. Therefore, it is suggested that most mutations in bacteria may not have any effect on survival. This is perhaps surprising when we think of bacteria evolution, especially in the context of human health and antibiotic resistance. This research is summarised in a guest post below.
