Use of Selected Plant Extracts in Controlling and Neutralizing Toxins and Sporozoites Associated with Necrotic Enteritis and Coccidiosis

Applied Sciences
Due to increasing concerns about the contamination of animal food products with antibiotic-resistant bacteria and their byproducts, phytogenic feed additives in animal diets have been explored as antibiotic alternatives.

Salmonella-vectored vaccine delivering three Clostridium perfringens antigens protects poultry against necrotic enteritis.

PLoS ONE, 2019
Necrotic enteritis is an economically important poultry disease caused by the bacterium Clostridium perfringens. There are currently no necrotic enteritis vaccines commercially available for use in broiler birds, the most important target population ...

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

, 2015
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

NetB-producing and beta2-producing Clostridium perfringens associated with subclinical necrotic enteritis in laying hens in the Netherlands [PDF]

, 2012
Since 2006 increasing numbers of laying hen flocks with decreased production have been reported in the Netherlands. At necropsy, birds from affected flocks showed multifocal areas of necrosis in the duodenum.

Prevalence of netB-positive Clostridium perfringens in Italian poultry flocks by environmental sampling

, 2019
Clostridium perfringens type G is one of the pathogens involved in enteric diseases in poultry. NetB, a poreforming toxin, is considered the main virulence factor responsible for necrotic enteritis during C. perfringens infection. We carried out a field

The light chain of tetanus toxin inhibits calcium-dependent vasopressin release from permeabilized nerve endings [PDF]

, 1992
The effects of tetanus toxin and its light and heavy chain subunits on vasopressin release were investigated in digitonin-permeabilized neurosecretory nerve terminals isolated from the neural lobe of the rat pituitary gland.

Determination of the virulence status of Clostridium perfringens strains using a chicken intestinal ligated loop model is important for understanding the pathogenesis of necrotic

Poultry Science
: Necrotic enteritis (NE) is a poultry intestinal disease caused by virulent strains of the bacterium Clostridium perfringens (C. perfringens). This anaerobic bacterium produces a wide range of enzymes and toxins in the gut which leads to NE development.

In silico Identification of Novel Toxin Homologs and Associated Mobile Genetic Elements in Clostridium perfringens

Pathogens, 2019
Clostridium perfringens causes a wide range of diseases in a variety of hosts, due to the production of a diverse set of toxins and extracellular enzymes. The C.

Exploring the functional domain and the target of the tetanus toxin light chain in neurohypophysial terminals [PDF]

, 1994
The tetanus toxin light chain blocks calcium induced vasopressin release from neurohypophysial nerve terminals. Here we show that histidine residue 233 within the putative zinc binding motif of the tetanus toxin light chain is essential for the ...
