Production of Clostridium difficile antitoxin.
نویسندگان
چکیده
We have produced antitoxin to the toxin of Clostridium difficile in rabbits and in goats. Antitoxin dilutions of 1/8,000 and 1/5,120 were capable of neutralizing lethal doses of the toxin in mice and in tissue culture, respectively.

Antitoxin production in antibiotic-associated colitis?
The production of antitoxin after Clostridium difficile-induced diarrhoea has not been reported previously. The stool of a patient with prolonged antibiotic-associated diarrhoea contained C. difficile toxin, and the serum neutralised the cytopathic effect of C. difficile toxin in tissue culture.
متن کاملEFFECT OF AMYGDALUS COMMUNIS ON GROWTH AND TOXIN PRODUCTION OF CLOSTRIDIUM DIFFICILE
It is known that the major etiologic agent of pseudomembranous colitis in man is Clostridium difficile. With respect to traditional use of almond paste in the treatment of infantile diarrhea, we studied the effects of the aqueous extract of Amygdalus communis (AEAC) on the growth and toxin production of Clostridium difficile in culture medium and the rabbit ligated ileal loop. Three groups...
متن کاملProtection against Clostridium difficile infection with broadly neutralizing antitoxin monoclonal antibodies.
The spore-forming bacterium Clostridium difficile represents the principal cause of hospital-acquired diarrhea and pseudomembranous colitis worldwide. C. difficile infection (CDI) is mediated by 2 bacterial toxins, A and B; neutralizing these toxins with monoclonal antibodies (mAbs) provides a potential nonantibiotic strategy for combating the rising prevalence, severity, and recurrence of CDI....
متن کاملNeutralization of Clostridium difficile toxin by Clostridium sordellii antitoxins.
Neutralization of Clostridium difficile toxin by Clostridium sordellii antitoxin was studied by cytotoxicity assay in tissue culture. The sources of toxin were stools from two patients with pseudomembranous colitis and a culture filtrate of C. difficile isolated from one of the patients. C. sordellii antitoxin was available either in monovalent form or as gas gangrene polyvalent antitoxin. The ...
متن کاملIdentification of toxigenic Clostridium difficile by counterimmunoelectrophoresis.
A counterimmunoelectrophoresis (CIE) technique which reacted positively with culture filtrates of Clostridium difficile was developed and compared with a cytotoxicity assay in human embryonic lung cell cultures. CIE, employing C. sordellii antitoxin, detected 17 of 17 C. difficile strains. Of those positive by CIE, 13 were cytotoxic in cell culture. Fourteen Clostridium species other than C. di...
