A persistent dictum in microbiology is that “everything is everywhere, and nature selects” (Beijerinck 1913), but molecular studies have made it apparent that microbial populations are often spatially subdivided (Papke et al. 2003; Whitaker et al. 2003). Local-scale d ...

Thus, an isolate classified as “susceptible” would be inhibited by the MIC at the site of infection, whereas a classification of “resistant” implies that an isolate would not be inhibited by this achievable concentration (CLSI, 2015). The “intermediate” cat ...

... Prokaryotes are involved in all three categories of symbiosis with eukaryotes. Legumes (peas, beans, alfalfa, and others) have lumps in their roots which are the homes of mutualistic prokaryotes (Rhizobium) that fix nitrogen that is used by the host. The plant provides sugars and other organic nutr ...

However, there is an amazing amount of DNA being swapped about among the enterics by conjugation with plasmid exchange, bacteriophages, and direct DNA insertion. When Escherichia coli acquire virulence in this manner, it can caus ...

Bacterial morphological plasticity

Bacterial morphological plasticity refers to evolutionary changes in the shape and size of bacterial cells. As bacteria evolve, morphology changes have to be made to maintain the consistency of the cell. However, this consistency could be affected in some circumstances (such as environmental stress) and changes in bacterial shape and size, but specially the transformation into filamentous organisms have been recently showed. These are survival strategies that affect the bacterial normal physiology in response for instance to innate immune response, predator sensing, quorum sensing and antimicrobial signs.
