Salmonella in poultry
Poultry can become infected with many different types of salmonella; about 10 percent of all Salmonella spp. have been detected in poultry. The most important are Salmonella Typhimurium and Salmonella Enteritidis. Other serotypes frequently occurring in poultry worldwide are, for example, Salmonella Hadar, Salmonella Livingstone, and Salmonella Senftenberg. In most cases, the birds are not sick and the production is not affected. The degree of illness depends on factors of both the bacteria and the host. The bacterium’s serotype and phage type is of significance but also the type of animal, age and general health status. S.Typhimurium and S. Enteritidis may induce clinical symptoms in poultry. It is mainly in very young chickens aged up to two weeks that salmonella can cause disease and death. The symptoms may vary and include weakness, loss of appetite and poor growth. The animals are crowded close to heat sources and sit with drooping wings and their eyes closed.
On the 20th-22nd of June, our Team participated in The International Symposium, Salmonella and Salmonellosis (I3S).
This initiative created by scientists from ANSES, is organized since 1992. Since the first edition, the I3S has been a great success and many scientists from all over the world still participate in this symposium which is now in its eighth edition. The attendees are from academic, governmental and industrial areas, all interested in Salmonella issues related to animals,...

I. EPIDEMIOLOGY OF SALMONELLA INFECTIONS Most Salmonella strains belong to non-host specific or broad-host range serotypes, and thus can colonize the gut of many animal species, including humans. In contrast to host-specific serotypes that cause septicemia and severe disease (typhoidal serotypes), the broad-host range serotypes are asymptomatically colonising the host in most cases, but can cause diarrhoea when high numbers of bacteria are orally take up at once, as is...

DESCRIPTION OF THE PROBLEM In the United States, foodborne nontyphoidal salmonellosis affects approximately one million individuals, results in 378 deaths and costs approximately $3.3 billion USD annually (Scallan et al., 2011). Most of these infections are associated with animal meat and product consumption, with poultry or poultry products being the major source (Marin and Lainez, 2009). Therefore, eradication of Salmonella in the production cycle of poultry and in processing...

Poultry farms act as an important source of transmission of antimicrobial-resistant (AMR) Salmonella to the environment as well as to humans. Indiscriminate and prophylactic use of antibiotics in poultry farms is one of the reasons behind it. Therefore, a cross-sectional study was conducted to determine the prevalence of Salmonella in broiler chickens, farm environments, as well as farmers to identify the risk factors for Salmonella colonization in broiler farms....

Introduction Poultry producers attempt to control infectious diseases through a variety of means, including appropriate farm management practices and breeding genetically resistant lines (Sartika et al. 2011; Scott et al. 2018). Unfortunately, existing farming conditions favour increased chicken densities in poultry houses, increasing the risk of spreading entero-pathogens such as Salmonella and Clostridium spp. (FAO 2013). For over half a century,...

This study evaluated the effect of probiotics, a prebiotic and essential oil blend and their combination on the growth of Salmonella Enteritidis (SE) in a digestive assay mimicking three digestive compartments of the poultry digestive tract: crop, proventriculus, and intestine. A poultry commensal Lactobacillus reuteri (LR) and SE strain were utilized. The prebiotic product was included at 0.025% (w/w) and probiotic product, a combination of 3 strains of Bacillus ...

Poultry products are the primary vehicle for broad-host, nontyphoidal Salmonella enterica contamination and foodborne disease in the United States 1,2 , causing 1.35 million infections and costing approximately $400 million annually3. Although extensive efforts have been made to minimize Salmonella incidence in poultry via antimicrobials, the spread of resistance genes has caused an emergence of Salmonella isolates resistant to essential antibiotics 3,4 . Furthermore, live...

Salmonella continues to be one of the bacteria that generates the greatest concern for the poultry sector. Not only because domestic poultry are carriers and vectors of Zoonotic Salmonella that cause toxiinfections (such as Salmonella enteritidis), but also because typhoid Salmonella (such as Salmonella Gallinarum) still exist in certain...

Introduction Salmonella is a major foodborne pathogen commonly associated with raw poultry and poultry products causing 1.2 million illnesses, 23,000 hospitalizations and 450 deaths, annually in the United States [1]. Between 2009 and 2015, 15% of the top 5 pathogen-food category pair out-breaks were attributed to Salmonellosis associated with chicken consumption [2]. To reduce the prevalence of Salmonella , poultry processors apply antimicrobial...
