“…Although the great majority of our wildlife ST128 isolates were pan-susceptible (14/15, 93.3%), we predicted a plasmid featuring three mobile AMR genes ( bla TEM-1 , dfrA1 and sul2 ) in one pigeon isolate from 2020. The occurrence of bla TEM-1 and sul1 / sul2 has been observed previously in S. Typhimurium isolates from pigeons in Poland [ 60 ] and Egypt [ 61 ].…”

What WGS Reveals about Salmonella enterica subsp. enterica in Wildlife in Germany

The aim of this study was to gain an overview of the genetic diversity of Salmonella found in wildlife in Germany. We were particularly interested in exploring whether wildlife acts as a reservoir of certain serovars/subtypes or antimicrobial resistance (AMR) genes. Moreover, we wanted to explore the potential of Salmonella in spreading from wildlife to livestock and humans. To answer these questions, we sequenced 260 Salmonella enterica subsp. enterica isolates sampled between 2002 and 2020 from wildlife across Germany, using short-read whole genome sequencing. We found, consistent with previous findings, that some Salmonella sequence types are associated with certain animal species, such as S. Choleraesuis ST145 with wild boar and S. Enteritidis ST183 with hedgehogs. Antibiotic resistance was detected in 14.2% of all isolates, with resistance against important WATCH group antibiotics present in a small number of isolates. We further found that wildlife isolates do not form separate phylogenetic clusters distant to isolates from domestic animals and foodstuff, thus indicating frequent transmission events between these reservoirs. Overall, our study shows that Salmonella in German wildlife are diverse, with a low AMR burden and close links to Salmonella populations of farm and food-production environments.

“…Choleraesuis, positive isolates scored positive for only one of the searched aminoglycosides resistance genes [ 47 , 48 ]. tetA was confirmed as the more frequent tetracycline resistance gene present among Salmonella [ 47 , 49 , 50 ]. Presence of bla TEM explained the resistance to Ampicillin in all but 2 resistant isolates.…”

Salmonella is one of the most important zoonotic pathogens worldwide. Swine represent typical reservoirs of this bacterium and a frequent source of human infection. Some intrinsic traits make some serovars or strains more virulent than others. Twenty-nine Salmonella spp. isolated from pigs belonging to 16 different serovars were analyzed for gastric acid environment resistance, presence of virulence genes (mgtC, rhuM, pipB, sopB, spvRBC, gipA, sodCI, sopE), antimicrobial resistance and presence of antimicrobial resistance genes (blaTEM, blaPSE-1, aadA1, aadA2, aphA1-lab, strA-strB, tetA, tetB, tetC, tetG, sul1, sul2, sul3). A percentage of 44.83% of strains showed constitutive and inducible gastric acid resistance, whereas 37.93% of strains became resistant only after induction. The genes sopB, pipB and mgtC were the most often detected, with 79.31%, 48.28% and 37.93% of positive strains, respectively. Salmonella virulence plasmid genes were detected in a S. enterica sup. houtenae ser. 40:z4,z23:-strain. Fifteen different virulence profiles were identified: one isolate (ser. Typhimurium) was positive for 6 genes, and 6 isolates (3 ser. Typhimurium, 2 ser. Typhimurium monophasic variant and 1 ser. Choleraesuis) scored positive for 5 genes. None of the isolates resulted resistant to cefotaxime and ciprofloxacin, while all isolates were susceptible to ceftazidime, colistin and gentamycin. Many strains were resistant to sulfonamide (75.86%), tetracycline (51.72%), streptomycin (48.28%) and ampicillin (31.03%). Twenty different resisto-types were identified. Six strains (4 ser. Typhimurium, 1 ser. Derby and 1 ser. Typhimurium monophasic variant) showed the ASSuT profile. Most detected resistance genes sul2 (34.48%), tetA (27.58%) and strA-strB (27.58%). Great variability was observed in analyzed strains. S. ser. Typhimurium was confirmed as one of the most virulent serovars. This study underlines that swine could be a reservoir and source of pathogenic Salmonella strains.

“…No amplification was obtained for sulI, tetR and bla CARB-2 genes in any of the isolates (Table 4). Kaczorek-Lukowska et al (2020) reported that tetA gene was among the most common antibiotic resistance genes that were isolated from domestic pigeons. Extensive use of tetracycline could have contributed to the selection of isolates with tetA gene.…”

Pigeon breeding has transformed from being a mere hobby to becoming established as an industry. The increased trade of pigeons inadvertently invites the risk of dissemination of infections including zoonoses like salmonellosis. Pigeons once infected remain carriers for life. This coupled with the ability of the organism to acquire antimicrobial resistance makes salmonellosis, particularly from pigeons an important, public health risk for pigeon handlers. Cloacal swabs from a total of 200 exotic pigeons belonging to 24 lofts from Northern districts of Kerala were collected and attempted to isolate Salmonella and understand its antimicrobial resistance profile. Five isolates of salmonella could be obtained from four of the lofts studied. A prevalence of 2.5 per cent was identified for salmonellosis with 16.67 per cent of the lofts affected. Antimicrobial sensitivity based on disk diffusion assay revealed that all the five isolates were sensitive to amoxicillin-clavulanate and all were resistant to tetracycline and streptomycin. Sixty per cent of the isolates were sensitive to co-trimoxazole, chloramphenicol, ampicillin, cefoperazone, amikacin and gentamicin.
