  1. ncbi Hypermutability impedes cooperation in pathogenic bacteria
    Freya Harrison
    Department of Zoology, University of Oxford, United Kingdom
    Curr Biol 15:1968-71. 2005
    ..Cheats appeared and increased in frequency more rapidly in mutator populations. The presence of cheats was costly to the group, as shown by a negative correlation between cheat frequency and population density...
  2. pmc Wider access to genotypic space facilitates loss of cooperation in a bacterial mutator
    Freya Harrison
    Department of Zoology, University of Oxford, Oxford, United Kingdom
    PLoS ONE 6:e17254. 2011
    ..This may represent a novel cost of hypermutability...
  3. ncbi Cooperative production of siderophores by Pseudomonas aeruginosa
    Freya Harrison
    Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS UK
    Front Biosci (Landmark Ed) 14:4113-26. 2009
    ..It is our hope that more realistic laboratory studies of siderophore cooperation in P. aeruginosa will eventually cast light on the roles played by social traits in long-term microbial infections...
  4. doi Interspecific competition and siderophore-mediated cooperation in Pseudomonas aeruginosa
    Freya Harrison
    Department of Zoology, University of Oxford, Oxford, UK
    ISME J 2:49-55. 2008
    ..This is probably because the S. aureus had the net effect of competing for iron, rather than acting as an iron source. This study demonstrates that interspecific competition can have a marked effect on intraspecific social interactions...
  5. ncbi Microbial ecology of the cystic fibrosis lung
    Freya Harrison
    Department of Zoology, University of Oxford, Oxford, UK
    Microbiology 153:917-23. 2007
    ..The results presented suggest that understanding the CF lung in terms of its community and evolutionary ecology could benefit our understanding of disease progression and influence treatment regimens...
  6. pmc High relatedness selects against hypermutability in bacterial metapopulations
    Freya Harrison
    Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS, UK
    Proc Biol Sci 274:1341-7. 2007
    ..These results may help to explain clinical distributions of mutator bacteria...
  7. pmc Cooperation and virulence in acute Pseudomonas aeruginosa infections
    Freya Harrison
    Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS, UK
    BMC Biol 4:21. 2006
    ..We tested this hypothesis using the cooperative production of iron-scavenging siderophores by the pathogenic bacterium Pseudomonas aeruginosa in an insect host...
  8. ncbi Siderophore-mediated cooperation and virulence in Pseudomonas aeruginosa
    Angus Buckling
    Department of Zoology, University of Oxford, Oxford, UK
    FEMS Microbiol Ecol 62:135-41. 2007
    ..Fourth, cooperative pyoverdin production is also shown to be favoured by kin selection in vivo (caterpillars), and results in more virulent infections. Finally, we briefly outline ongoing and future work using this experimental system...
  9. doi Siderophore production and biofilm formation as linked social traits
    Freya Harrison
    Department of Zoology, University of Oxford, Oxford, UK
    ISME J 3:632-4. 2009
    ..Reduced biofilm formation therefore represents a pleiotropic cost of defection from siderophore production...
  10. pmc Exploring the effects of working for endowments on behaviour in standard economic games
    Freya Harrison
    Department of Zoology, University of Oxford, Oxford, United Kingdom
    PLoS ONE 6:e27623. 2011
    ..Our data are not unduly worrying, but they do suggest that further exploration is needed if we are to make general inferences about human behaviour from the results of structured economic games...
  11. pmc Strength of social tie predicts cooperative investment in a human social network
    Freya Harrison
    Department of Zoology, University of Oxford, Oxford, United Kingdom
    PLoS ONE 6:e18338. 2011
    ..Interestingly, participants regularly suffered greater discomfort for very close peers than for themselves. Our results provide new insight into the effect of social structure on the direct benefits of cooperation...
