  • The fascinating and frustrating (for researchers like me) story of Vampirococcus.
  • Vampirococcus summary for new #Micronauts.
  • An overview of Agrobacterium, a bacterium about which all micronauts should know (think about genetic engineering in agriculture!).
  • The story of Pelagibacter, very probably the most abundant organism on Earth.  
  •  The story of Akkermansia, and its impact on metabolic health and the gut microbiome.
  • An important essay by the late Dr. Elio Schaechter regarding paradigm shifts in microbiology.  Much recommended!
  • A truly wonderful video about bacteriophages and their importance.
  • A simple video explaining the life cycle of lytic and lysogenic bacteriophages.
  • video from the American Society of Microbiology linking CRISPR and bacteriophages.
  • review of genes "hitchhiking" in bacteriophages.
  • An introduction to Phollow technology.
  • An overview and discussion of the Phollow technology discussed in this podcast (paywalled).  
  • A Phollow related publication also discussed during the podcast.
  • The Wiles laboratory, where Dr. de Ora Ortiz and colleagues developed the Phollow technology.
  • Dr. Travis Wiles' episode of #MattersMicrobial. 
  • The Secor laboratory, where Dr. de Ora Ortiz currently works.
  • Dr. de Ora Ortiz's LinkedIn profile.
