·      7.A. Microbiomes and their effects.

o   Human microbiome composition and effects.

The composition of our microbiome affects

  • metabolism and digestion over the course of our lifetime (Turnbaugh and Gordon 2009; Tilg and Kaser 2011; Romano-Keeler, Weitkamp et al. 2012; Kundu, Blacher et al. 2017)
  • changes during pregnancy (Koren, Goodrich et al. 2012)
  • our immune responses (Doerflinger, Throop et al. 2014; Salvucci 2014) (including autoimmunity (Boerner and Sarvetnick 2011)
  • cancer immunotherapy (Zitvogel, Ma et al. 2018))
  • our states of mind (Cryan and O'Mahony 2011; Dash, Clarke et al. 2015; Allen, Dinan et al. 2017; Hoban, Stilling et al. 2017).

 

o   Each organ or area of the human body has its own microbiome

 

§  Different skin regions and mucosal surfaces (Gill, Pop et al. 2006; Aziz 2009; Grice, Kong et al. 2009; Hamady and Knight 2009; Peterson, Garges et al. 2009; Ellrott, Jaroszewski et al. 2010; Jones, Sun et al. 2010; Kuczynski, Costello et al. 2010; Grice and Segre 2011; Moissl-Eichinger, Probst et al. 2017; Chen, Fischbach et al. 2018)

·      Throat (Jakobsson, Jernberg et al. 2010)

 

§  The gut microbiome (Gill, Pop et al. 2006; Aziz 2009; Turnbaugh and Gordon 2009; Ellrott, Jaroszewski et al. 2010; Kinross, Darzi et al. 2011)

·      suppresses invasion by bacterial pathogens (Peixoto, Alves et al. 2017)

·      Pathogen elimination by probiotic Bacillus via signalling interference of Staphylococcus aureus (Piewngam, Zheng et al. 2018).

§  Previously unknown bacterial taxa discovered in gut microbiome (Nelson, Weinstock et al. 2010; Consortium 2012; Wylie, Truty et al. 2012).

 

o   Human gut microbiome coding capacity. Estimates of the genomic coding complexity of the human gut microbiome range from 3.3 to 9.9 million distinct proteins, or 150X - 450X greater than the basic human proteome (Yang, Xie et al. 2009; Zhu, Wang et al. 2010; Donia, Cimermancic et al. 2014; Li, Jia et al. 2014). When the diverse microbiomes existing in and on other body locations are considered (Grice and Segre 2012), the difference becomes even more striking. (Zhu, Wang et al. 2010)

 

o   Non-human microbiomes. (Suen, Scott et al. 2010; Shin, Kim et al. 2011; Berg Miller, Yeoman et al. 2012; Cho, Yamanishi et al. 2012; Hentschel, Piel et al. 2012; Looft and Allen 2012; Lundberg, Lebeis et al. 2012; Cheng, Tian et al. 2013; Weiss, Wang et al. 2013; Passos da Silva, Castaneda-Ojeda et al. 2014; Pinto, Pinho et al. 2014; Edwards, Johnson et al. 2015; Lebeis, Paredes et al. 2015; Panke-Buisse, Poole et al. 2015; Sunagawa, Coelho et al. 2015; Vandenkoornhuyse, Quaiser et al. 2015; Zarraonaindia, Owens et al. 2015; Agler, Ruhe et al. 2016; Berg, Rybakova et al. 2016; Liu, Carvalhais et al. 2017; Murillo-Rincon, Klimovich et al. 2017; Perez-Jaramillo, Carrion et al. 2017; Stolz 2017; Garcia-Bonilla, Brandao et al. 2018; Ivens, Gadau et al. 2018; Moissl-Eichinger, Pausan et al. 2018; Raymann and Moran 2018)

 

o   Bacterial-Archaeal Syntrophy and Conflict: (Stams and Plugge 2009; Edgcomb, Leadbetter et al. 2011; Wrede, Dreier et al. 2012; Atanasova, Pietila et al. 2013; Anderson, Sogin et al. 2014; Wegener, Krukenberg et al. 2015; Koskinen, Pausan et al. 2017; Moissl-Eichinger, Probst et al. 2017; Jin, Li et al. 2018; Moissl-Eichinger, Pausan et al. 2018)

 

·      7.B. Holobiont evolution

 

o   Holobiont concept. (Margulis 1991; Zrzavy and Skala 1993; Guerrero, Margulis et al. 2013; Salvucci 2014; Bordenstein and Theis 2015; Vandenkoornhuyse, Quaiser et al. 2015; Diaz-Munoz, Boddy et al. 2016; Rosenberg and Zilber-Rosenberg 2016; Shropshire and Bordenstein 2016; Theis, Dheilly et al. 2016; Adair and Douglas 2017; Koskella, Hall et al. 2017; Rees, Bosch et al. 2018; Rosenberg and Zilber-Rosenberg 2018; Sandoval-Motta, Aldana et al. 2018)

 

o   The term “holobiont” applied to metazoa: sponges (Pita, Rix et al. 2018), corals holobiont (Thompson, Rivera et al. 2014; van de Water, Allemand et al. 2018), tsetse flies (Snyder and Rio 2013), and bark beetles (Six 2013).

 

o   Amoeba and other protists that are phagocytic, engulf other microorganisms, and serve as hosts to bacteria like Legionella, Helicobacter, Listeria, and Mycobacterium that also infect animal cells (Gomez-Valero and Buchrieser 2013; Yousuf, Siddiqui et al. 2013; Hoffmann, Harrison et al. 2014).

 

o   Protist “Melting Pots” In other words, Acanthamoeba protists and animal guts constitute evolutionary “melting pots,” where new adaptations can arise and then be transferred symbiotically to other organisms (Boyer, Yutin et al. 2009; Moliner, Fournier et al. 2010; Shterzer and Mizrahi 2015; Guimaraes, Gomes et al. 2016; Wang and Wu 2017).
