Since the 2006 European ban on the use of antibiotics as growth promoters in animal feed, numerous studies have been published describing alternative strategies to prevent diseases in animals. A particular focus has been on prevention of necrotic enteritis in poultry caused by Clostridium perfringens by the use of microbes or microbe-derived products. Microbes produce a plethora of molecules wi...

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, detection of these genes has been performe...

The study was conducted to investigate the effects of wheat based diet on the pathology of necrotic enteritis in turkeys. Turkeys were divided into four groups. Groups A and B were kept as noninoculated and fed normal commercial diet while groups C and D were challenged orally with C. perfringens and fed wheat based diet to promote the development of experimental disease. Infected turkeys showe...

Necrotic enteritis (NE) is one of the most important bacterial diseases in terms of economic losses. Clostridium perfringens necrotic enteritis toxin B, NetB, was recently proposed as a new key virulent factor for the development of NE. The goal of this work was to develop a necrotic enteritis model in chickens by using a Japanese isolate of C. perfringens. The Japanese isolate has been found t...

Necrotic enteritis poses an important health risk to broilers. The ionophore anticoccidials lasalocid, salinomycin, maduramicin, narasin and a combination of narasin and nicarbazin were tested in feed for their prophylactic effect on the incidence of necrotic enteritis in a subclinical experimental infection model that uses coccidia as a predisposing factor. In addition, drinking water medicati...
