Medical Applications of Clostridia and Clostridial Toxins
The bacterial genus Clostridium produces a diverse array of protein toxins, many of which have played an important role in disease and medicine. Although initially known for their ability to do harm, many clostridial toxins have been shown to have therapeutic value for a diverse array of diseases. The articles included in this special issue provide insight into some of that diversity and show t...
متن کاملAnalyses of Wound Exudates for Clostridial Toxins.
Noyes, Howard E. (Walter Reed Army Institute of Research, Washington, D.C.), William L. Pritchard, Floyd B. Brinkley, and Janice A. Mendelson. Analyses of wound exudates for clostridial toxins. J. Bacteriol. 87:623-629. 1964.-Earlier studies indicated that death of goats with traumatic wounds of the hindquarter could be related to the number of clostridia in the wounds, and that toxicity of wou...
متن کاملADP-ribosylation of actin by clostridial toxins
umber of clostridial bacteria produce toxins which ADP-ribosylate monomeric actin. These include botulinum C2 toxin (2), Clostridiumperfringens iota toxin (23, 26), Clostridium spiroforme toxin (20, 27), and an ADP-ribosyltransferase produced by Clostridium difficile (21). The toxins have turned out to be valuable tools for investigating the actin cytoskeleton since ADP-ribosylation of actin bl...
متن کاملClostridial Binary Toxins: Iota and C2 Family Portraits
There are many pathogenic Clostridium species with diverse virulence factors that include protein toxins. Some of these bacteria, such as C. botulinum, C. difficile, C. perfringens, and C. spiroforme, cause enteric problems in animals as well as humans. These often fatal diseases can partly be attributed to binary protein toxins that follow a classic AB paradigm. Within a targeted cell, all clo...
متن کاملClostridial C3 Toxins Target Monocytes/Macrophages and Modulate Their Functions
The C3 enzymes from Clostridium (C.) botulinum (C3bot) and Clostridium limosum (C3lim) are single chain protein toxins of about 25 kDa that mono-ADP-ribosylate Rho-A, -B, and -C in the cytosol of mammalian cells. We discovered that both C3 proteins are selectively internalized into the cytosol of monocytes and macrophages by an endocytotic mechanism, comparable to bacterial AB-type toxins, whil...
