Abstract
Studies about in vitro pellicle formation by slow-growing, pathogenic mycobacteria has just gained a new momentum, and in Mycobacterium tuberculosis, cells growing in this environment showed enhanced tolerance to antitubercular drugs. c-di-GMP, an ubiquitous bacterial second messenger, regulates phenotypes such as motility, biofilm formation and expression of acute virulence factors in several microorganisms. Recently, enzymes encoded by Rv1354c and Rv1357c were shown to produce and degrade c-di-GMP in vitro, respectively. Here we review the processes in which c-di-GMP regulates biofilm production and virulence in some human pathogens, discuss the possibility of these same processes existing in Mycobacterium tuberculosis, and how these mechanisms could impact the outcome of tuberculosis infection.
Keywords: Biofilm, c-di-GMP, EAL, GGDEF, virulence.

Exposure to PM2.5 components is associated with respiratory diseases
Through continuous research on the relationship between risk factors and health, it has been found that air pollution, especially atmospheric particulate matter pollution, has become one of the main sources of global disease burden. From 1990 to 2022, the concentration of atmospheric particulate matter pollution has increased by more than ...read more
