“…In 2011, a high frequency of resistance to this antimicrobial agent was already reported (79%) [81]. Those high frequencies were also observed throughout the decade, with values in different collections of isolates, such as 54.5% in 2015 [80], 97.4% in 2017 [84], and 88.1% in 2019 [85]. Resistance to beta-lactams was also commonly found.…”

“…Resistance frequencies to folate inhibitors are generally high but variable, similar to the strains isolated from poultry [35,37,38,40,42,52,80,81,83,84]. However, the frequency of aminoglycoside resistance frequencies is generally higher in Salmonella strains isolated from pigs (Tables 1 and 2) [38,41,52,75,81,84,85].…”

“…Studies published in 2011 and 2015 pointed to ampicillin resistance frequencies of 29% and 46% [80,81]. However, the few studies released in the following years with Brazilian isolates suggest a rising rate of resistance to ampicillin and amoxicillin, with reports as high as 80% to 90% of the isolates in studies published in 2017 and 2019 [84,85]. That trend was not observed for cephalosporins resistance with low prevalence hitherto described [81,85].…”

“…isolates was not evaluate or was lower than 4% [80,81,83,84]. In contrast, in 2019, Viana et al identified up to 50% of resistance to ciprofloxacin among 112 isolates obtained from pig lots that have undergone prophylaxis with ciprofloxacin during growing and finishing production steps [85]. Regarding nalidixic acid, studies report rising rates over the years, from 5% in 2011 [73] to values varying from 30% to 60% in 2015 and 2016 [80,83,84].…”

In animal husbandry, antimicrobial agents have been administered as supplements to increase production over the last 60 years. Large-scale animal production has increased the importance of antibiotic management because it may favor the evolution of antimicrobial resistance and select resistant strains. Brazil is a significant producer and exporter of animal-derived food. Although Brazil is still preparing a national surveillance plan, several changes in legislation and timely programs have been implemented. Thus, Brazilian data on antimicrobial resistance in bacteria associated with animals come from official programs and the scientific community. This review aims to update and discuss the available Brazilian data on this topic, emphasizing legal aspects, incidence, and genetics of the resistance reported by studies published since 2009, focusing on farm animals and derived foods with the most global public health impact. Studies are related to poultry, cattle, and pigs, and mainly concentrate on non-typhoid Salmonella, Escherichia coli, and Staphylococcus aureus. We also describe legal aspects of antimicrobial use in this context; and the current occurrence of genetic elements associated with resistance to beta-lactams, colistin, and fluoroquinolones, among other antimicrobial agents. Data here presented may be useful to provide a better understanding of the Brazilian status on antimicrobial resistance related to farm animals and animal-derived food products.

“…In pigs, Salmonella is also a matter of concern, being that a great diversity of serotypes have been reported, isolated in pig feces, lymph nodes/tonsils, and subproducts (1,8,(11)(12)(13)(14)(15)(16)(17)(18). S. Choleraesuis, serotype adapted to pigs, often cause the septicemic form of the disease, while S. Typhimurium is responsible for the enterocolitic form of the disease (19,20).…”

Background: Salmonella contamination of raw meat-based diets (RMBDs) for pets poses a major public health concern but has not been investigated in Japan.Objective: To investigate Salmonella contamination in RMBDs for dogs marketed in Japan and the anti-microbial resistance profiles of the Salmonella isolates.Methods: Sixty commercial RMBD samples were collected in the Okayama and Osaka Prefectures, Japan, between December 2016 and March 2017. The obtained Salmonella isolates were serotyped, their anti-microbial resistance patterns were determined, and the anti-microbial-resistant isolates were screened for the presence of resistance genes by polymerase chain reaction.Results: Salmonella enterica subsp. enterica was detected in seven of the 60 RMBD samples. Among them, five isolates were identified as S. Infantis (n = 3), S. Typhimurium (n = 1) and S. Schwarzengrund (n = 1), while the serotypes of two isolates were unable to be identified. All isolates were susceptible to ampicillin, cefazolin, cefotaxime and gentamycin. Two isolates were resistant to more than one anti-microbial agent; one of the S. Infantis isolates was resistant to streptomycin, kanamycin, tetracycline and trimethoprim, while the S. Typhimurium isolate was resistant to nalidixic acid, ciprofloxacin and chloramphenicol. The S. Schwarzengrund isolate was resistant to tetracycline. Additionally, the S. Typhimurium isolate harboured the anti-microbial resistance gene gyrA with a mutation corresponding to Ser-83→Phe amino acid substitution. Conclusion:The study findings suggest that RMBDs for dogs marketed in Japan can be a potential source of Salmonella infection for dogs and humans including infections caused by quinolone-resistant isolates.
