Intracellular Movement of Viruses and Bacteria

2.8K
Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...

Actin Polymerization and Cell Motility

5.2K
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.
Actin cytoskeleton dynamics can produce pushing, pulling, and resistance forces that help the cell to migrate....

Cytoskeletal Proteins in Bacteria01:29

Cytoskeletal Proteins in Bacteria

3.4K
Bacterial cells were initially considered simple, randomly organized structures lacking a cytoskeleton. However, the discovery of cytoskeleton homologs in bacteria led to the change of this opinion. Bacterial cytoskeletal filaments regulate the cell shape, cell polarity, cell division, and partitioning of plasmids during cell division. It was later discovered that bacterial cytoskeletal proteins, mainly actin and tubulin homologs, are diverse compared to their eukaryotic counterparts. On the...

Area of Science:

  • Microbiology
  • Biophysics

Background:

  • Bacterial surfaces trigger changes in swimming behavior, crucial for biofilm development.
  • Increased intracellular cyclic di-GMP (c-di-GMP) reduces swimming speed during initial surface contact.

Purpose of the Study:

  • To investigate the impact of bacterial swimming speed on surface swimming behavior.
  • To understand how speed influences cell-surface interactions and biofilm formation.

Main Methods:

  • Advanced microscopy techniques to observe bacterial swimming.
  • Hydrodynamic modeling to explain observed behaviors.
  • Comparative analysis of *Escherichia coli* and *Pseudomonas aeruginosa*.

Main Results:

  • Decreased swimming speed reduces cell-surface distance and prolongs surface trapping time.
  • Increased swimming speed leads to a larger radius of curvature and shorter surface detention time.
  • Distinct surface-escaping mechanisms were identified between *E. coli* and *P. aeruginosa*.

Conclusions:

  • Reduced bacterial swimming speed enhances surface sensing and adhesion, promoting biofilm formation.
  • Swimming speed is a key factor in the transition from motile to sedentary bacterial states.
  • Understanding these mechanisms is vital for controlling bacterial colonization and biofilm development.
