Pore-forming toxins (PFTs) are a diverse group of cytolytic proteins that are produced by many different organisms (1, 2). Bacterial PFTs are important virulence factors (1) and in general are produced as soluble precursors that bind to the host cell membrane and assemble as oligomers that subsequently form transmembrane pores (3, 4).
PFTs can be divided into two classes depending on whether the ...

Clostridium perfringens is a bacterial pathogen that causes a wide variety of diseases ranging from gas gangrene and food poisoning in humans to necrotic enteritis in chickens . Aside from host factors, the type and severity of disease is dependent on the production of a set of toxins and extracellular enzymes . Most C. perfringens toxins are not produced by all strains; their st ...

Chicken meat production is more sustainable and has lower environmental impact than porcine and bovine meat production. Chicken production uses less feed consumed for each kilogram of meat produced and uses less land and water for both farming and feed production (Flachowsky et al., 2017). Moreover, the broiler production industry has, for many years, continuously improved animal performance, refl ...

Wheat, maize and sorghum are the three most commonly used grains in the poultry industry worldwide (Liu et al., 2014). These cereal grains usually constitute a major proportion (60 - 70%) of the diet fed to broilers (Black et al., 2005). Although cereals represent a major source of energy for birds, there are wide variations in the energy and nutrient content of different species and ...

The avian ceca generally have a more important role in digestion than the cecum in most mammals. Avian ceca are usually finger-shaped blind pouches, presenting as lateral extensions at the junction of the small and large intestine and are commonly present in pairs. In birds the ceca vary considerably in size and morphology; ranging from very long, such as in most domestic poultry, to c ...

The gut microbiota is made up of complex interacting populations of microbes, usually dominated not only by bacteria but also archea, eukaryotes and viruses. There is a rapidly growing body of evidence that demonstrates that the microbiota has diverse and wide-ranging roles in many biological functions of the host. The integration of host and microbiota is so important and fundamenta ...

A range of studies have investigated the structure of the microbiome in the gut of broiler chickens. Comparison across studies has proven difficult because of the variety of different methods used; e.g. culture based studies , G+C profiling analysis , quantitative PCR , and 16S rRNA based studies. The 16S-based methods have used a number of different approaches including ter ...

The gastrointestinal tract (GIT) microbiota of humans and animals consists of complex populations that include many different species of bacteria along with smaller numbers of fungi, protozoa, and archaea (Zoetendal et al., 2006). Over the last decade our understanding of the diverse functional roles and interactions of the GIT microbiota has rapidly advanced (Zoetendal et al., 2006) ...
