• A prompt for my course:  an article on "Animals in a Microbial World," with so many interesting examples.  Here is a summary for novice #Micronauts.
• A prompt for my course:  an article by the late, great Lynn Margulis on the nature of kefir grains and the definition of multicellularity and the organism.
• A prompt for my course:  an article on hyperpolyploidy in bacteria.
• An explanation of "genomic islands."
• A link to a previous guest of #MattersMicrobial, Dr. Laura Williams, discussing Bdellovibrio and undergraduate based research.
• An overview of predatory bacteria. Here is a more recent overview.  
• An overview of the predator Myxococcus.
• A wonderful video showing the predatory process of Myxococcus. 
• A fine review of the predator Bdellovibrio. 
• A video of the life cycle of Bdellovibrio. 
• Some work by Dr. Koval and colleagues suggesting that aspects of the outer cell wall is not involved with resistance to Bdellovibrio.
• Recent VERY exciting work suggesting that there is indeed a receptor on bacteria that Bdellovibrio can recognize. Here is a short summary of that work.  
• Could Bdellovibrio become a "living antibiotic"?
• A reminder from Drs. Kolter and Losick that bacteria in the laboratory can be quite different from their relatives in nature.
