“…Furthermore, a prevalence of 5.5 % of Salmonella spp. was reported in a study of healthy and diarrheic calves from the western region of Buenos Aires province, and treatment of diarrhea with antibiotics was likewise not reported in this study (Bilbao et al, 2019).…”

“…Accordingly, a low infection rate of 1.7% has been reported in diarrheic calves sampled from 1994 to 2010 in ten different provinces of Argentina (Bok et al, 2015). Enteropathogenic E. coli (ETEC) was found in dairy calves of younger age (< 10 days old) (Bartels et al 2010;Cho et al 2013;Al Mawly et al 2015a;Picco et al 2015;González Pasayo et al 2019), whereas prevalence values of 5.9% (1 to 53-dayold calves) (Bilbao et al, 2019) and 4% (9 to 21-day-old calves) have been observed…”

“…Notably, independent studies have demonstrated the prevalence and importance of the enteropathogens C. parvum and RVA, and, to a lesser degree, of BCoV, Escherichia coli and Salmonella, in the etiology of diarrhea of dairy calves in Argentina J o u r n a l P r e -p r o o f Journal Pre-proof (Del Coco, 2008;Tiranti et al, 2011;Badaracco et al, 2012;Bok et al, 2015;Picco et al, 2015;Garro et al, 2016;Bilbao et al, 2019;Lombardelli et al, 2019). However, a study that demonstrates and compares the association of each agent with diarrhea in calves and/or detects the occurrence of possible synergetic effects of coinfections has not yet been carried out in Argentina.…”

“…In a recent study involving 50 dairy farms in Argentina, S. enterica was detected in 36% of the farms, and the most prevalent serotypes were Mbandaka, Anatum, Typhimurium, Dublin, and Montevideo [6]. In Uruguay, S. Typhimurium was the most frequently isolated serotype in a study performed in 30 dairy farms with spontaneous outbreaks of neonatal calf diarrhea, while the serotype Anatum was isolated in a small subset of diarrheic and healthy calves [7].…”

“…These samples were from two diarrhoeic and one nondiarrheic calves. Salmonella Anatum has been isolated from dairy and beef calves [22,23] but the role of this serotype as a causative agent of diarrhoea in neonate calves still needs to be elucidated. Recently, a human salmonellosis outbreak was reported due to food contamination with this serotype [24].…”

Antibiotic resistance in Salmonella enterica isolated from dairy calves in Uruguay

Salmonella enterica is an important animal and human pathogen that can cause enteritis and septicaemia in calves. Generally, antibiotics are prescribed for the treatment of salmonellosis in dairy calves. Here, we report the isolation of antibiotic resistant S. enterica serotypes from calves, including multidrug-resistant isolates. A total of 544 faecal samples from live healthy and diarrheic dairy calves from 29 commercial dairy farms and organ samples from 19 deceased calves that succumbed to salmonellosis in 12 commercial dairy farms in Uruguay were processed for selective S. enterica culture. In total, 41 isolates were serotyped, and susceptibility to 14 antibiotics, from 9 classes of compounds, was evaluated by disk-diffusion test. The minimum inhibitory concentration (MIC) was determined by microdilution. Salmonella Typhimurium was the most frequent serotype, followed by S. Dublin and S. Anatum. Whether determined by diffusion assay or microdilution, resistance to tetracycline, streptomycin and ampicillin were the most frequently pattern found. Based on MIC, 5 isolates were resistant to at least one antibiotic, 21 were resistant to 2 antibiotics, and 14 were multidrug-resistant (resistant to at least one antibiotic in 3 different categories of antibiotics). Eleven different resistance patterns were found. Multidrug resistance in S. enterica is a concern for animal and public health not only because of its zoonotic potential but also due to the possibility of transfer resistance determinants to other bacterial genera. This represents the first report of the antibiotic resistance in S. enterica in dairy farms in Uruguay. Keywords Salmonella Typhimurium. Salmonella Dublin. Salmonella Anatum. Antibiotic resistance. Dairy calves Salmonella enterica is an important pathogen that affects a wide range of animal species and humans. More than 2500 serotypes are documented within Salmonella spp. but only a few affect cattle [1]. In this species, Salmonella Dublin and Salmonella Typhimurium are by far the most frequent serotypes [2, 3], and can cause enteritis, diarrhoea and septicaemia [4, 5]. Salmonellosis in calves is often treated with antibiotics and ß-lactams, and sulphonamides are recommended in cases of septicaemia [6, 7]. When resistance to these antibiotics is suspected or confirmed, quinolones are the next therapeutic option, but emergence of resistance to this group of antibiotics has also been reported [8]. Moreover, antibiotics have been used as feed additives for decades [9, 10], which has promoted the occurrence and selection of resistant and multidrug-resistant (MDR) strains, affecting the therapeutic performance of antibiotics in both animals and humans [9]. The World Health Organization (WHO) recommendations point toward the preservation of antibiotics for human use, reducing their use in animals, and the promotion of sanitation and hygienic practices to avoid disease and, therefore, the use of antibiotics [10]. Multidrug resistance is an emerging issue worldwide, and the transference of resistance me...
