Cytolytic pore-forming toxins are important for the virulence of many disease-causing bacteria. How target cells molecularly respond to these toxins and whether or not they can mount a defense are poorly understood. By using microarrays, we demonstrate that the nematode Caenorhabditis elegans responds robustly to Cry5B, a member of the pore-forming Crystal toxin family made by Bacillus thuringi...
Clostridium septicum alpha-toxin is a beta-barrel pore-forming cytolysin that is functionally similar to aerolysin. Residues important in receptor binding, oligomerization, and pore formation have been identified; however, little is known about the activity of the toxin in an infection, although it is essential for disease. We have now shown that deletion of a small portion of the transmembrane...
In this paper, we have investigated the effects of the pore-forming toxin aerolysin, produced by Aeromonas hydrophila, on mammalian cells. Our data indicate that the protoxin binds to an 80-kD glycosyl-phosphatidylinositol (GPI)-anchored protein on BHK cells, and that the bound toxin is associated with specialized plasma membrane domains, described as detergent-insoluble microdomains, or choles...
Glycosylphosphatidylinositol (GPI) is synthesized and transferred to proteins in the endoplasmic reticulum (ER). GPI-anchored proteins are then transported from the ER to the plasma membrane through the Golgi apparatus. To date, at least 17 steps have been identified to be required for the GPI biosynthetic pathway. Here, we aimed to establish a comprehensive screening method to identify genes i...
Aeromonas septicemia is a life threatening bacterial infection in fishes, concurrently in human with weakened immune systems. Present research work aims to isolate and identify the virulent strains of motile Aeromonas species linked with the septicemia in 12 fresh water cat fishes (Clarius batrachus) in the locality of Sathyamangalam, Tamil Nadu. A total of 72 samples consisting of intestinal c...
