EFFECT OF CONTROLLED pH ON TOXINOGENESIS BY CLOSTRIDIUM PERFRINGENS TYPE D

Canadian Journal of Microbiology, 1965
A strain of Clostridium perfringens type D was grown in a complex medium with or without pH control. Rate and extent of growth was the same without pH control and at controlled pH levels between 6.0 and 7.4, but was reduced at pH 7.6. With controlled pH at optimum levels the yields of alpha, epsilon, kappa, and theta toxins were 2, 6, 2, and 8 times ...

An outbreak of enterotoxaemia caused by Clostridium perfringens type D in goats in Patagonia

Veterinary Record, 1994
Forty-four of a flock of 117 angora goats in the Rio Negro province of Argentina died within four days. Most of the animals died shortly after the onset of clinical signs, but in a few the clinical course lasted for several days. Post mortem the small and large intestines were filled with watery contents, blood and fibrin clots, and there were numerous

Studies on ϵ-prototoxin of Clostridium perfringens type D

Archives of Biochemistry and Biophysics, 1964
Purified prototoxin of Clostridium perfringens type D was separated by column chromatography on CM-cellulose or DEAE-cellulose into two and three fractions respectively. The fractions exhibited prototoxin activity and showed immunochemical identity. The purified prototoxin gave a single component in the ultracentrifuge with a sedimentation constant of ...

A STUDY OF THE SOLUBLE ANTIGENS OF CLOSTRIDIUM PERFRINGENS TYPE D

Canadian Journal of Microbiology, 1964
The soluble antigens of Clostridium perfringens type D have been separated into four fractions by chromatography on DEAE-cellulose. The fractions were examined for their biological activity and for their homogeneity by starch gel electrophoresis, double diffusion in agar, and immunoelectrophoresis.

Separation of Clostridium Perfringens Type D Toxins

The Journal of Immunology, 1965
Summary A method was developed for the complete separation of Clostridium perfringens type D toxins. ε and θ toxins were separated from each other and from the remaining toxins on a single column of diethylaminoethyl cellulose.

Effects of Intravenous Injection of Clostridium perfringens Type D Epsilon Toxin in Calves

Journal of Comparative Pathology, 2002
In cattle, a neurological lesion similar to that produced in sheep and goats by Clostridium perfringens type D enterotoxaemia has been reported. However, no causal relationship has been established between this disease and the lesion in cattle. The effects of single and multiple intravenous injections of epsilon toxin in three calves aged 6 months were

Clostridium perfringens toxins (type A, B, C, D, E)

Pharmacology & Therapeutics, 1980
Abstract Clostridum perfringens types A,B,C,D, and E produce at least 12 different antigens, referred to as toxins , that may be involved in pathogenesis . These antigens have been given the names alpha, beta, epsilon , and iota toxin (‘major’ toxins), and delta, theta, kappa (collagenase), lambda (protease), mu (hyaluronidase), nu ...

AN ENTEROTOXIN PRODUCED BY CLOSTRIDIUM PERFRINGENS TYPE D. PURIFICATION BY AFFINITY CHROMATOGRAPHY

Acta Pathologica Microbiologica Scandinavica Section B Microbiology, 1976
Clostridium perfringens type D 9867 produced enterotoxin immunologically identical to that produced by types A and C which are responsible for C. perfringens food poisoning. Enterotoxin from type C 5386 and type D 9867 was produced in Duncan og Strong sporulation medium (DS medium).

The production and evaluation of monoclonal antibodies to Clostridium perfringens type D epsilon toxin

Journal of Biological Standardization, 1988
The production of five monoclonal antibodies to the epsilon prototoxin of Clostridium perfringens is described. All five monoclonal antibodies located three proteins in a trypsinized preparation of epsilon prototoxin. These proteins were located at 37.6 kDal, 35.6 kDal and 33.7 kDal by Western blots.

Neurological disorders produced by Clostridium perfringens type D epsilon toxin

Anaerobe, 2004
Although the epsilon toxin of Clostridium perfringens type D produces disease in many species of domestic livestock, neurological disturbance is more common and better studied in sheep. High levels of circulating toxin, especially in lambs, cause cerebral microvascular endothelial damage with disruption of the blood-brain barrier leading to a severe ...
