Clostridium Difficile Toxin A+B Rapid Test
Clostridium Difficile Toxin A+B Rapid Test provides a procedure for a qualitative detection of Clostridium difficile toxin A (TcdA) and toxin B (TcdB) in two separate bands. A positive band of either toxin is a sign of an underlying Clostridium difficile infection (CDI), which should attract the attention of the physician. Samples used are liquid or semi-liquid human stool samples. Care must be...
متن کاملIn silico fusion of epsilon and beta toxin genes of Clostridium perfringens types D and B
Fusion protein technology represents the strategy to achieve rapid, efficient, and cost-effective proteinexpression. Epsilon and Beta toxins are the most potent Clostridial toxins and cause disease in animals.This study describes in silico fusion of Clostridium perfringens types D and B epsilon and beta toxin genesthat was used for cloning in E.coli. The etx and cpb genes were...
متن کاملTitration of kappa toxin of Clostridium perfringens and kappa antitoxin by a modified azocoll method.
Azo-dye was liberated from azocoll not only by proteolytic enzymes but also by albumin (serum or egg), a culture medium (papain digest of meat) or polyvinylpyrrolidone (PVP). Pretreatment of azocoll with papain and PVP increased the reactivity of azocoll to ƒÈ-toxin of Clostridium perfringens. A rapid and reliable assay method of ƒÈ-toxin and ƒÈ-antitoxin using the pretreated azocoll is described.
متن کاملToxin–antitoxin systems
Toxin-antitoxin (TA) systems are small genetic elements composed of a toxin gene and its cognate antitoxin. The toxins of all known TA systems are proteins while the antitoxins are either proteins or non-coding RNAs. Based on the molecular nature of the antitoxin and its mode of interaction with the toxin the TA modules are currently grouped into five classes. In general, the toxin is more stab...
متن کاملMetal Ion Activation of Clostridium sordellii Lethal Toxin and Clostridium difficile Toxin B
Lethal Toxin from Clostridium sordellii (TcsL) and Toxin B from Clostridium difficile (TcdB) belong to the family of the "Large clostridial glycosylating toxins." These toxins mono-O-glucosylate low molecular weight GTPases of the Rho and Ras families by exploiting UDP-glucose as a hexose donor. TcsL is casually involved in the toxic shock syndrome and the gas gangrene. TcdB-together with Toxin...
