“…In the last few years, the S. Heidelberg serotype has also emerged in various countries such as Argentina 32 , Brazil 33 and Europe 20 . This serotype has been observed in other studies 32,33 and has also been involved in foodborne outbreaks 34 . The increasing isolation of S. Heidelberg, as well as its antimicrobial resistance in our region 35 , highlights its emergence, spread and maintenance in the environment, and reinforces the need to improve measures for prevention and surveillance.…”

Salmonellosis ranks among the most frequently reported zoonosis worldwide and is often associated with foodborne outbreaks. Since the 1950s, the distribution of Salmonella serotypes in Sao Paulo State, Brazil, has been documented and periodically reported. In this study, we updated the data on the distribution of Salmonella serotypes received in our reference laboratory, isolated from human infections and nonhuman sources, from 2004 to 2020. In that period, a total of 9,014 Salmonella isolates were analyzed, of which 3,553 (39.4%) were recovered from human samples, mainly of stool (65%) and blood (25.6%), and 5,461 (60.6%) were isolated from nonhuman origins, such as animals (47.2%), food (27.7%) and animal environments (18.6%). In human isolates, a total of 104 serotypes were identified and the most frequent ones were Enteritidis, Typhimurium, S. I. 4,[5],12:i:-, Dublin and Typhi. A consistent reduction of the Enteritidis proportion was observed over the years. Among the 156 serotypes identified in isolates with nonhuman origins, Enteritidis, Mbandaka, Typhimurium, Agona and Anatum were ranked as the top five Salmonella serotypes; in more recent years, S. Heidelberg has increased in frequency. Although with different proportions, the top 10 prevalent serotypes were identified in both human and nonhuman origins, underscoring the role of animals, food products and environment as reservoirs of Salmonella with potential to cause human salmonellosis.

“…In the past 2 decades, there has been a significant uptick in research attention towards probiotics, particularly lactic acid bacteria ( LAB ), as substitutes for growth promoters and in combating Salmonella intestinal colonization in broilers ( Elhariri et al, 2020 ; Dominguez et al, 2021 ). Numerous studies have highlighted the effectiveness of probiotic isolates in suppressing the growth of Salmonella spp.…”

“…This genetic analysis can assess the genetic diversity of the entire genome. It is the gold standard method due to its accuracy and reproducibility [ 26 , 27 , 28 , 29 ]. First, isolates collected from different farms belonging to the same integrated company had the same PFGE type (for example, type 1 in B1, B2, and B3 farms belonging to company B; type 4 in A1, A3, A4, A5 and A6 farms belonging to company A).…”

Antimicrobial resistance and pulsed-field gel electrophoresis (PFGE) genotypes of collected S. enterica ser. Gallinarum isolates were investigated to examine the epidemiological relationship between field outbreak isolates of S. enterica ser. Gallinarum. Thirty S. enterica ser. Gallinarum isolates collected from poultry farms with FT outbreaks from 2013 to 2018 in South Korea were analyzed. All isolates were resistant to at least 3 of the 18 antimicrobials tested and exhibited an MDR phenotype. All isolates showed resistance to streptomycin, sulfisoxazole, and colistin. One isolate was resistant to 9 antimicrobials. The antimicrobial resistance profile, streptomycin-sulfisoxazole-colistin-nalidixic acid-ciprofloxacin-gentamicin (18/30, 60.0%), was the most prevalent. PFGE types were classified into 10 groups with a 100% correlation cutoff in dendrograms for 30 field isolates. The dominant PFGE types were 1 (8/30, 26.7%), 4 (7/30, 23.3%), and 9 (5/30, 16.7%). Interestingly some isolates collected from the same and different companies had the same PFGE type. We reported a high MDR rate in S. enterica ser. Gallinarum isolates. The present study highlights the occurrence of horizontal spread and cyclic contamination of MDR S. enterica ser. Gallinarum within the same company. Furthermore, we showed cross-contamination between different companies. The characterization of these isolates would be helpful in the development of prevention and control strategies for MDR S. enterica ser. Gallinarum infection in South Korea.
