This example of polyphenism, where distinct morphs are produced through the same genotype, is associated with nutritional resources, whereby scarcity of bacteria induces the development of the predatory morph [ 31].
The change would pull many government inspectors off the slaughtering line where they visually inspect birds, moving resources instead toward the detection of bacteria and other invisible dangers.
The stringent response is the reallocation of cellular resources in bacteria under nutrient limitation, by prohibiting the synthesis of DNA, stable RNAs, ribosomal proteins and membrane components, and activating the synthesis of factors involved in amino acid synthesis, glycolysis and stress resistance [ 65].
In flies and other invertebrates, lysozyme expression and activity increase after exposure to bacteria, and the species-specific gene number partly depends on the use of bacteria as food resource [ 5].
Instead of genotype testing (because resources were limited), we used the resistance spectra of bacteria to differentiate nosocomial from primary infection.
The population dynamics of bacteria competing for a single resource in chemostat or ecological systems of phytoplankton are examples.
Unc and Goss ([2004]) evaluated the influence of manure on the transport of bacteria from land receiving manure to water resources.
It is therefore interesting to search for the genetic resource of natural clostridial bacteria for the application in bioengineering.
The treatment is thought to work by restoring the gut's natural balance of bacteria, which can outcompete the invading microbes for resources.
Figure 2 shows timeseries of resource concentration, total bacteria and phage density, and the density distribution of bacteria and phage in genotype space, together with fields showing bacteria/phage fitness landscapes over time, for an exemplar case study simulation.
