Environmental ecology review presents how microbial life strategy concepts are applied in complex microbial communities.   Two interesting model systems are described in the techniques section, plus potentially scalable workflow for the preparation of high potency Akkermansia muciniphila cells for therapeutic interventions.  The importance of understanding the role of the microbiome in preventing complications after organ transplant and surgeries are discussed in two reviews.   Another study shows that proton pump inhibitors used to prevent gastric ulcers were associated with distinct gut microbiota signatures.  For faster wound healing, try some saliva. A study shows the beneficial effects of saliva on wound healing in human epidermal keratinocytes and on the attenuation of intracellular Staph. aureus infection.

Every surfer knows you should stay out of the water for 72 hours after it rains. Public health officials issued an advisory for all Los Angeles County beaches, cautioning swimmers and surfers to stay away from areas near storm drains, creeks and rivers. But when the waves show – some surfers just can’t help themselves.
