  text: Herd immunity, a process in which resistant individuals limit the spread of
    a pathogen among susceptible hosts has been extensively studied in eukaryotes.
    Even though bacteria have evolved multiple immune systems against their phage
    pathogens, herd immunity in bacteria remains unexplored. Here we experimentally
    demonstrate that herd immunity arises during phage epidemics in structured and
    unstructured Escherichia coli populations consisting of differing frequencies
    of susceptible and resistant cells harboring CRISPR immunity. In addition, we
    develop a mathematical model that quantifies how herd immunity is affected by
    spatial population structure, bacterial growth rate, and phage replication rate.
    Using our model we infer a general epidemiological rule describing the relative
    speed of an epidemic in partially resistant spatially structured populations.
    Our experimental and theoretical findings indicate that herd immunity may be important
    in bacterial communities, allowing for stable coexistence of bacteria and their
    phages and the maintenance of polymorphism in bacterial immunity.

  text: Bacteria and their pathogens – phages – are the most abundant living entities
    on Earth. Throughout their coevolution, bacteria have evolved multiple immune
    systems to overcome the ubiquitous threat from the phages. Although the molecu-
    lar details of these immune systems’ functions are relatively well understood,
    their epidemiological consequences for the phage-bacterial communities have been
    largely neglected. In this thesis we employed both experimental and theoretical
    methods to explore whether herd and social immunity may arise in bacterial popu-
    lations. Using our experimental system consisting of Escherichia coli strains
    with a CRISPR based immunity to the T7 phage we show that herd immunity arises
    in phage-bacterial communities and that it is accentuated when the populations
    are spatially structured. By fitting a mathematical model, we inferred expressions
    for the herd immunity threshold and the velocity of spread of a phage epidemic
    in partially resistant bacterial populations, which both depend on the bacterial
    growth rate, phage burst size and phage latent period. We also investigated the
    poten- tial for social immunity in Streptococcus thermophilus and its phage 2972
    using a bioinformatic analysis of potentially coding short open reading frames
    with a signalling signature, encoded within the CRISPR associated genes. Subsequently,
    we tested one identified potentially signalling peptide and found that its addition
    to a phage-challenged culture increases probability of survival of bacteria two
    fold, although the results were only marginally significant. Together, these results
    demonstrate that the ubiquitous arms races between bacteria and phages have further
    consequences at the level of the population.
