Multidrug Resistance and Virulence Profiles of Salmonella Isolated from Swine Lymph Nodes

Protective Effects of Grape Seed Oligomeric Proanthocyanidins in IPEC-J2–Escherichia coli/Salmonella Typhimurium Co-Culture

“…Escherichia coli and Salmonella enterica ser. Typhimurium are among the main Gram-negative pathogens causing gastrointestinal (GI) infections in humans and pigs [ 9 , 10 , 11 ]. Furthermore, the former is commonly associated to the latter as both bacteria are zoonotic, and foodborne transmission with pork products represents a significant proportion of human cases [ 10 , 11 , 12 , 13 ].…”

“…Typhimurium are among the main Gram-negative pathogens causing gastrointestinal (GI) infections in humans and pigs [ 9 , 10 , 11 ]. Furthermore, the former is commonly associated to the latter as both bacteria are zoonotic, and foodborne transmission with pork products represents a significant proportion of human cases [ 10 , 11 , 12 , 13 ]. These bacteria, when isolated from humans, animals and food of animal origin, are frequently resistant to multiple antibiotics [ 14 ] and are able to transfer their resistance genes to further microorganisms [ 11 ], leading to the spread of antimicrobial resistance along the food chain.…”

Epidemiological investigation on drug resistance of Salmonella isolates from duck breeding farms in Shandong Province and surrounding areas, China

“…However, due to the long-term abuse and misuse of antibiotics, the phenomenon of multidrug resistance has become more and more serious in recent years ( dos Reis et al, 2018 ; Qiao et al, 2018 ). According to reports, the multidrug-resistant ( MDR ) rates of Salmonella isolated from patients, chicken, and swine all exceeded 70% ( Kalonji et al, 2015 ; Song et al, 2020 ; de Azevedo et al, 2021 ).…”

Resistência à colistina e aos β-lactâmicos em isolados de Escherichia coli oriundos de bovinos, suínos e humanos de um abatedouro misto

“…A alta incidência de isolados resistentes em suínos quando comparados com bovinos pode ser explicada pelo fato de esses animais serem submetidos ao sistema de criação intensivo, justificando o maior uso deste antimicrobiano nesta produção (Huang et al, 2017;Zhang et al, 2019). No Brasil, dados não oficiais relatam a utilização de até sete classes de antibióticos, incluindo β-lactâmicos e colistina, como forma preventiva ou terapêutica nas granjas suínas (Azevedo et al, 2021).…”

“…Analisando os perfis de resistência, 30 tipos diferentes foram relatados nos isolados desse abatedouro misto, sendo que 21 perfis são pertencentes à cadeia suína, reforçando dados da literatura sobre a dispersão de bactérias multidroga resistentes (Azevedo et al, 2021;Possebon et al, 2020;Viana et al, 2019Viana et al, , 2020.…”
