“…In Spain, only one strain with this characteristic has been described (Navarro-Gonzalez et al, 2012) and, in Italy, a 1.8-0.8% of resistance to nalidixic acid was reported (Zottola et al, 2013), besides a 3.4% rate in Salmonella from other wild animals (Botti et al, 2013). All nalidixic acid-resistant isolates from the present study displayed an intermediate sensitivity to enrofloxacin, as previously described (Astorga et al, 2007;Caleja et al, 2011a;Foti et al, 2018;Gomez-Laguna et al, 2011). Although MIC determination by microdilution is more appropriate for fluoroquinolone resistance in Salmonella (Parry et al, 2010) than the disk diffusion technique used in this study, the pattern observed must be related to detected gyrA genotypes, D87Y or D87N, closely linked to nalidixic acid resistance (Levy et al, 2004;Palomo Guijarro, 2011;Rahmani et al, 2013).…”

Antimicrobial resistance (AMR) is a global concern and controlling its spread is critical for the effectiveness of antibiotics. Members of the genus Salmonella are broadly distributed, and wild boar may play an important role in its circulation between periurban areas and the environment, due to its frequent interactions both with livestock or human garbage. As the population of these animals is rising due to management on certain hunting estates or the absence of natural predators, the aim of the present work is to identify the mechanisms of AMR present and/or expressed in Salmonella spp. from wild boar populations and to determine the possible role of managementrelated factors applied to different game estates located in central Spain. The detection of Salmonella spp. was carried out in 121 dead wild boar from 24 game estates, and antimicrobial resistance traits were determined by antibiotic susceptibility testing and screening for their genetic determinants. The effects of feeding supplementation, the proximity of livestock, the existence of a surrounding fence and the density of wild boar on the AMR of the isolates were evaluated. The predominant subspecies and serovar found were S. enterica subsp. enterica (n = 69) and S. choleraesuis (n = 33), respectively. The other subspecies found were S. enterica subsp. diarizonae, S. enterica subsp. salamae and S. enterica subsp. houtenae. AMR was common among isolates (75.2%) and 15.7% showed multi drug resistance (MDR). Resistance to sulphonamides was the most frequent (85.7%), as well as sul1 which was the AMR determinant most commonly found.Plasmids appeared in 38.8% of the isolates, with IncHI1 being the replicon detected with the highest prevalence. The AMR of the isolates increased when the animals were raised with feeding supplementation and enclosed by fences around the estates.

“…These data are in accordance with the prevalence of yersiniosis and biotypes distribution in wild boar [22,85,86]. As for Salmonella, other sources of infection cannot be definitively excluded; although Y. enterocolitica has been isolated from resident and migratory wild fauna in Italy [87,88], no recent data on the investigated area are available to allow a robust hypothesis. Among isolates belonging to biotype 1, only one virulence gene (within ail, ystA, ystB, and virF) was detected, while in biotype 4 the ystA, ystB, and inv genes were detected.…”

Domestic dogs (Canis lupus familiaris) used for wild boar (Sus scrofa) hunting may represent incidental hosts for several zoonotic pathogens. This investigation aimed to evaluate the presence of anti-Leptospira antibodies and the occurrence, antimicrobial resistance, and virulence of Salmonella spp., Yersinia enterocolitica, and Listeria monocytogenes in sera and rectal swabs collected from 42 domestic hunting dogs in the Tuscany region (Italy). Regarding Leptospira, 31 out of 42 serum samples (73.8%) were positive and serogroup Pomona was the most detected (71.4%) at titers between 1:100 and 1:400. Four Salmonella isolates (9.52%) were obtained, all belonging to serotype Infantis; two of them showed antimicrobial resistance to streptomycin, while pipB and sopE presence was assessed in all but one isolate. Concerning Yersinia enterocolitica, seven isolates (16.7%) were obtained, six belonging to biotype 1 and one to biotype 4. Resistance to amoxicillin–clavulanic acid, cephalothin, and ampicillin was detected. Biotype 4 presented three of the virulence genes searched (ystA, ystB, inv), while isolates of biotype 1 showed only one gene. No Listeria monocytogenes was isolated from dog rectal swabs. The results suggest that hunting dogs are exposed to different bacterial zoonotic agents, potentially linked to their work activity, and highlight the possible health risks for humans.
