Tracking Salmonella enterica by whole genome sequencing of isolates recovered from broiler chickens in a poultry production system

Genomic Characterization of Antimicrobial-Resistant Salmonella enterica in Duck, Chicken, and Pig Farms and Retail Markets in Eastern China

“…These serovars were detected throughout the samples collected from both provinces, including farms and live animal markets. S. Kentucky has been previously reported as the dominant serovar in chicken slaughterhouses in Jiangsu Province ( 31 ) and chicken broilers in Sichuan Province ( 32 ) in China. In contrast, several previous works reported S. Typhimurium as a dominant serovar in chicken ( 33 , 34 ), ducks ( 34 ), and pigs ( 35 ) in China.…”

Characterization of Extensively Drug-Resistant Salmonella enterica Serovar Kentucky Sequence Type 198 Isolates from Chicken Meat Products in Xuancheng, China

“…Recently, S . Kentucky ST198 became the second most prevalent serotype (3.10% [13/420 strains]) in the production chain of broiler chickens in Sichuan Province, China ( 13 ). It has also been increasingly detected in animals and clinics in countries outside China, e.g., India (3.49% in animals and 0.31% in patients), East Africa, Spain, and Switzerland ( 16 – 19 ).…”

“…MDR S . Kentucky ST198 has been sporadically reported in broiler chickens, poultry meat, slaughterhouse, and vegetable in China ( 12 – 15 ). In this study, we investigated the characterization of extensively drug-resistant S .…”

Epidemiological links and antimicrobial resistance of clinical Salmonella enterica ST198 isolates: a nationwide microbial population genomic study in Switzerland

“…Poultry and poultry products are assumed to be major vehicles for the spread of S . Kentucky ST198 and clonal transmission within poultry farms and processing facilities has been reported, but ST198 has also been identified in other animals and foods [14, 18, 20, 69–71].…”

“…Two SNP clusters could be linked with meat or animal feed isolates from Switzerland, pointing towards contamination of the animal food processing chain as a possible source. Poultry and poultry products are assumed to be major vehicles for the spread of S. Kentucky ST198 and clonal transmission within poultry farms and processing facilities has been reported, but ST198 has also been identified in other animals and foods [14,18,20,[69][70][71].…”
