By the way - What is EMC? EMC - a definition. EMC means nothing more than an electronic or electrical product shall work as intended in its environment. The electronic or electrical product shall not generate electromagnetic disturbances, which may influence other products. In other words, EMC deals with problems of noise emission as well as noise immunity of electronic and electrical products and systems.
The traditional âgold standardâ for identifying toxinogenic Clostridium difficile is the cell cytotoxicity test. A laboratory cell line is exposed to toxin B in fecal eluate. C. diff is confirmed when an antitoxin reverses the effects of the toxin on the cells.
C. difficile large clostridial toxins Clostridium difficile, as all clostridia, is a toxin producing microorganism and the toxins are the main virulence factors. In the early eighties it was clear that two large toxins are produced by the bacterium and epidemiological studies have indicated that strains either produce both toxins (toxin A, TcdA, and toxin B, TcdB) or none of them.
