Most bacterial pathogens have the remarkable ability to flourish in the external environment
and in specialized host niches. This ability requires their metabolism, physiology, and …

Bacteria of the genus Legionella are natural pathogens of amoebae that can cause a severe
pneumonia in humans called Legionnaires' Disease. Human disease results from inhalation …

The genus Legionella contains more than 50 species, of which at least 24 have been
associated with human infection. The best-characterized member of the genus, Legionella …

Practical Handbook of Microbiology, 4th edition provides basic, clear and concise
knowledge and practical information about working with microorganisms. Useful to anyone …

Like for all microbes, the goal of every pathogen is to survive and replicate. However, to
overcome the formidable defenses of their hosts, pathogens are also endowed with traits …

In many γ‐proteobacteria, the conserved GacS/GacA (BarA/UvrY) two‐component system
positively controls the expression of one to five genes specifying small RNAs (sRNAs) that …

The small nucleotides pppGpp and ppGpp (or (p) ppGpp) are rapidly synthesized in
response to nutritional stress. In Escherichia coli, the enzymes RelA and SpoT are triggered …

Diverse interactions between hosts and microbes are initiated by the detection of host-
released chemical signals. Detection of these signals leads to altered patterns of gene …

Flagellar motility helps bacteria to reach the most favourable environments and to
successfully compete with other micro-organisms. These complex organelles also play an …
