“…In any case, the isolation rate of Salmonella in slaughterhouses and chicken products was higher than in farms, which is an important Salmonella link between chicken production and food [ 30 ]. The variations in Salmonella isolation rates could be due to differences in region or season, or differences in the sampling techniques used across studies [ 31 ]. The poultry farming industry in Anhui Province is large, and according to statistics, there was an average annual stock of 70–80 million egg-laying hens and an average annual slaughter of 180–200 million broiler chickens in 2020–2022 (unofficial data).…”

Salmonella is one of the most important zoonotic pathogens that can cause both acute and chronic illnesses in poultry flocks, and can also be transmitted to humans from infected poultry. The purpose of this study was to investigate the prevalence, antimicrobial resistance, and molecular characteristics of Salmonella isolated from diseased and clinically healthy chickens in Anhui, China. In total, 108 Salmonella isolates (5.66%) were successfully recovered from chicken samples (n = 1908), including pathological tissue (57/408, 13.97%) and cloacal swabs (51/1500, 3.40%), and S. Enteritidis (43.52%), S. Typhimurium (23.15%), and S. Pullorum (10.19%) were the three most prevalent isolates. Salmonella isolates showed high rates of resistance to penicillin (61.11%), tetracyclines (47.22% to tetracycline and 45.37% to doxycycline), and sulfonamides (48.89%), and all isolates were susceptible to imipenem and polymyxin B. In total, 43.52% isolates were multidrug-resistant and had complex antimicrobial resistance patterns. The majority of isolates harbored cat1 (77.78%), blaTEM (61.11%), and blaCMY-2 (63.89%) genes, and the antimicrobial resistance genes in the isolates were significantly positively correlated with their corresponding resistance phenotype. Salmonella isolates carry high rates of virulence genes, with some of these reaching 100% (invA, mgtC, and stn). Fifty-seven isolates (52.78%) were biofilm-producing. The 108 isolates were classified into 12 sequence types (STs), whereby ST11 (43.51%) was the most prevalent, followed by ST19 (20.37%) and ST92 (13.89%). In conclusion, Salmonella infection in chicken flocks is still serious in Anhui Province, and not only causes disease in chickens but might also pose a threat to public health security.

“…Federally licensed autogenous vaccines can be used to tailor the vaccination strategy to further decrease prevalence and level of contamination of the carcasses at the processing plant [37,38]. As several types of salmonella can be present at different levels of the poultry production [39][40][41], it has been recommended to consider Salmonella enterica isolates/serovars found at processing plant monitoring as autogenous vaccine candidates [42]. This is because these isolates have successfully overcome the different control strategies already in place and are the most likely to find their way to human consumers and cause food-borne illness.…”

Emergent economically important diseases affecting the poultry industry in the face of commercial vaccination programs in place might require custom-made vaccines to be controlled in the field. These custom-made vaccines (“autogenous”), albeit requiring less regulatory burden than fully licensed commercial vaccines, are restricted in their scope and field isolates and can only be used in particular areas/operations. This chapter summarizes field and research experience of the author with some viral and bacterial autogenous vaccine programs (e.g., Avian Reovirus, Fowl Adenovirus, Infectious Bursal Disease Virus, Salmonella enterica spp., Escherichia coli, Clostridium spp.), as well as commentaries on regulations, and adjuvant technologies used in the poultry industry.
