Mosquitocidal bacterial toxins: diversity, mode of action and resistance phenomena.

Bacteria active against dipteran larvae (mosquitoes and black flies) include a wide variety of Bacillus thuringiensis and B. sphaericus strains, as well as isolates of Brevibacillus laterosporus and Clostridium bifermentans. All display different spectra and levels of activity correlated with the nature of the toxins, mainly produced during the sporulation process. This paper describes the stru...

The Clostridium Difficile Toxins: Mechanism of Action and Immunopathogenesis

Clostridium difficile infection (CDI) is now the most common definable cause of hospital-acquired and antibiotic-associated diarrhea in the United States, with the total cost of treatment estimated between 1 to 4.8 billion U.S. dollars annually (Dubberke and Olsen, 2012; DuPont, 2011; Kyne et al., 2002; Magill et al., 2014; O'Brien et al., 2007; Wilkins and Lyerly, 2003). This bacterium is resp...

Clostridium difficile toxins: mechanism of action and role in disease.

As the leading cause of hospital-acquired diarrhea, Clostridium difficile colonizes the large bowel of patients undergoing antibiotic therapy and produces two toxins, which cause notable disease pathologies. These two toxins, TcdA and TcdB, are encoded on a pathogenicity locus along with negative and positive regulators of their expression. Following expression and release from the bacterium, T...

Mechanism of Action of the Thyroid Hormone on the Heart

SUMMARY  The foliowing cardiac effects may be at­tributed to thyroxin:  1-Thyroxin augments all anaerobic pro­cesses in the body includ::ng the heart, and decreases the glycogen content of the heart ( 1, 2, 5, 27). The resistance of the heart to anoxia is increased in hyperthyroidism ( 25). 2- Thyroxin influences the cardiac weight and prevents cardiac atrophy (3, 8, 10, 11, 19, 20, 21, 30...

Antibacterial Activity of Polypyrrole-Chitosan Nanocomposite: Mechanism of Action

Polypyrrole-chitosan nanocomposite (PPy-CTN) was synthesized by dispersion polymerization of PPy in presence of CTN. Preparation of spherical PPy nanoparticles that were successfully covered with a thin layer of chitosan was confirm by transmission electron microscopy (TEM) technique. Characterization techniques also revealed the presence of CNT in the polymer matrix and its presence was confir...
