Necrotizing Infectious Enteritis in Piglets, Caused by Clostridium Perfringens Type C
I. Biochemical and Toxigenic Properties of the Clostridium
Acta Veterinaria Scandinavica volume 8, pages 26–38 (1967)
Twenty Danish and 3 foreign strains of the porcine subtype of Cl. perfringens type G have been studied with regard to biochemical activity and toxin formation.
The strains examined showed no deviation from the biochemical features characteristic of Gl. perfringens. Two of the strains showed delayed fermentation of saccharose, 1 of them also of salicin. Only 3 of the strains gave a positive nitrite reaction. The rest of the strains (20) presumably reduced nitrate to NH3 within 3 days.
All of the strains examined produced the major antigens α and β, none of them ε and ι. Of the minor antigens, θ and v were produced by all the strains, x by 2 of the foreign strains and 5 of the Danish strains. None of the strains gave reaction for the δ, λ and μ antigens.
Some of the Danish strains were hemolytic in the presence of α, δ, and θ antitoxins, others not, while a few varied. The foreign strains were non-αδθ hemolytic.
