Diffusion of Clostridium perfringens NetB positive strains in healthy and diseased chickens

Italian Journal of Animal Science, 2010
For over 30 years α toxin was considered the key virulence factor responsible for the appearance of necrotic enteritis (NE) in chickens but, recently, a new toxin related to the occurrence of NE, called NetB, has been described.

Variable protection against experimental broiler necrotic enteritis after immunisation with the C-terminal fragment of Clostridium perfringens alpha-toxin and a non-toxic NetB variant [PDF]

Avian Pathology, 2016
Necrotic enteritis toxin B (NetB) is a pore-forming toxin produced by Clostridium perfringens and has been shown to play a key role in avian necrotic enteritis (NE), a disease causing significant costs to the poultry production industry worldwide.

Use of a Multiplex PCR for the Detection of Toxin‐Encoding Genes netB and tpeL in Strains of Clostridium perfringens [PDF]

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
Some studies have shown that the NetB toxin may be an important virulence factor of Clostridium perfringens associated necrotic enteritis in poultry. Additionally, research has shown that strains of C. perfringens positive for both the netB gene and a second toxin‐encoding gene, tpeL, appear to be more virulent than strains with only netB. In the past,

Genetic and functional analysis of the novel toxin NetB from clostridium perfringens chicken necrotic enteritis isolates

, 2017
The overall objective of this thesis was to develop a structural and functional understanding of NetB toxin from chicken necrotic enteritis isolate of Clostridium perfringens. The thesis contains a literature review, three published papers presenting the

Vaccination with recombinant NetB toxin partially protects broiler chickens from necrotic enteritis. [PDF]

Vet Res, 2013
NetB toxin from Clostridium perfringens is a major virulence factor in necrotic enteritis in poultry. In this study the efficacy of NetB as a vaccine antigen to protect chickens from necrotic enteritis was examined. Broiler chickens were immunized subcutaneously with purified recombinant NetB (rNetB), formalin treated bacterin and cell free toxoid with
