Campylobacter jejuni is a predominant cause of human gastroenteritis worldwide. Source-attribution studies indicate that chickens are the main reservoir for infection, thus elimination of C. jejuni from poultry would significantly reduce the burden of human disease. We constructed glycoconjugate vaccines combining the conserved C. jejuni N-glycan with a protein carrier, GlycoTag, or fused to th...

Aquatic birds are the natural hosts of type A influenza viruses. Influenza viruses are categorized by the glycoprotein spikes on their surface – the ‘HA’ or haemagglutinin protein (16 different subtypes identified so far) and the ‘NA’ or neuraminidase protein (nine subtypes). All 16 HA and nine NA subtypes (see box on Terminology) have been detected in various combinations in aquatic wild birds...

Gut microbiota is formed by ten of trillions of microorganisms with at least 1000 different species of known bacteria. One - third of an individual gut microbiota is common to most people, while two - thirds are specific to him. Growing amount of evidence indicates that gut microbiota characteristics may play an important role in mental dysfunctions. Molecular mimicry between several key neurop...

Listeria monocytogenes is a foodborne pathogen that can cause febrile gastroenteritis in healthy subjects and systemic infections in immunocompromised individuals. Despite the high prevalence of L. monocytogenes in the environment and frequent contamination of uncooked meat and poultry products, infections with this pathogen are relatively uncommon, suggesting that protective defenses in the ge...

Over the last decade, the rapid emergence of multidrug-resistant pathogens has become a global concern, which has prompted the search for alternative antibacterial agents for use in food animals. Antimicrobial peptides (AMPs), produced by bacteria, insects, amphibians and mammals, as well as by chemical synthesis, are possible candidates for the design of new antimicrobial agents because of the...

Nutritional advances as discussed in these proceedings embrace historical perspective as well as futuristic perspectives. Indeed, we must have a clear understanding of the past to identify key “advances” that will mold the future of poultry nutrition. Early nutrition research is discussed with reference to in ovo nutrition and nutritional needs up to day seven post-hatch. In addition, the nutri...

Prebiotics are non-digestible food ingredients that stimulate the growth of bifidogenic and lactic acid bacteria in the gastro-intestinal tract. Typically, the prebiotics consist of dietary fibers and oligosaccharides. Prebiotics exert a plethora of health-promoting effects, owing to which multi million food and pharma industries have been established. Prebiotics are being implicated in starter...

| The carvacrol compound is an antioxidant nutrient, used to enhance growth and productive performance via modification and activation of gastrointestinal tract structure and function and to inhibit/prevent cancer initiations. Numerous studies performed on animal diets supplemented with phytogenic supplements/feed additives containing natural antioxidants such as carvacrol demonstrated its capa...

alzheimer’s disease (ad) is a neurodegenerative disease that is the most common type of dementia.ad includes 60_80% of dementia and most people with ad have more than 65 years old.ad causes losing neuronal activity by abnormal proteins. plaques of beta-amyloid and tangles of “tau” protein can lead to ad. recently evidence has found that ad may come from outside of central nervous system (cns) a...
