“…The AMR situation in wild birds in the densely populated but also intensively used agricultural region between Austria and Czech Republic has not been investigated so far in detail. Available studies were limited to ESBL producing E. coli and Enterococci or methicillin-resistant Staphylococcus aureus (MRSA) within certain bird species (Loncaric et al 2013;Dolejska et al 2007Dolejska et al , 2009. n.a.…”

“…Then, separately for both countries and for each order of bird, the minimum, median, first and third quartile and maximum were calculated. Significant differences between the mean values of Austrian and Czech isolates are labelled (**p ≤ 0.01; *p ≤ 0.05) and the numbers of Austrian (AT) and Czech (CZ) isolates are given in parenthesis Bacteria isolated from migrating birds and birds of aquaticassociated species (waterfowl, gulls and waders) are shown to carry more antibiotic resistances than other species (Loncaric et al 2013). This could partially be confirmed in our study: E. coli isolated from Anseriformes, Apodiformes and Piciformes had the highest mean AMR values, but for the last two orders, the number of tested samples was too low to draw a significant conclusion.…”

The antimicrobial resistance (AMR) of E. coli, Salmonella spp. and thermophilic Campylobacter spp. isolated from wild birds in the Austrian-Czech border region, predominantly within the vicinity of Vienna and Brno, was determined. Bacteria were isolated from cloacal swabs taken from 53 avian species belonging to 14 orders, the majority being feral pigeons and various songbirds. Consequently, 1978 E. coli, 24 Salmonella and 99 Campylobacter isolates were tested by microdilution method against a panel of 14 (E. coli and Salmonella spp.) or ten antimicrobial substances (Campylobacter spp.). The AMR varied greatly between Austrian and Czech isolates, between different bird and bacterial species and between the different antimicrobials without consistent trends being recognizable. In 331 from 664 birds, differences in the AMR profile between the two or three E. coli isolates from the same bird were observed. Concerning E. coli, the least effective antimicrobial was cephalotin (90.8% of isolates resistant); for Campylobacter it was trimethoprim-sulfamethoxazole (71.4% of isolates resistant). None of the antimicrobials was effective against all E. coli or Campylobacter isolates. In contrast, more than half of the antimicrobials were effective against all Salmonella isolates, but 71.4% of the Czech Salmonella isolates and all of the Austrian Salmonella isolates were multi-resistant (resistant to three or more antimicrobial substances); streptomycin being the least effective antimicrobial substance (90.5% of isolates resistant). It is concluded that AMR in zoonotic bacteria from wild birds in the investigated densely populated areas is widespread and diverse, arguing for certain care at the wildlifehuman interface, but AMR to clinically important and critical antimicrobials is relatively low.

“…The transferability of β-lactamase and PMQR genes was performed by mating on 10 randomly selected ESC-R E. coli isolates with azide-resistant E. coli J53 (J53 AZ r ) as described previously (Loncaric et al, 2013). Transconjugants were selected on Mueller-Hinton (MH) agar supplemented with 150 μg/ml sodium azide and 2 μg/ml cefotaxime.…”

Objective: The aim of this study was to investigate the occurrence and molecular characterization of extended-spectrum β-lactamases (ESBL), plasmid-mediated AmpC β-lactamase (pAmpC) and carbapenemases as well as plasmid-mediated quinolone-resistant (PMQR) among extended-spectrum cephalosporin-resistant (ESC-R) Escherichia coli from dogs in Shaanxi province in China.Methods: A total of 40 ESC-R Escherichia coli selected from 165 Extraintestinal pathogenic E. coli (ExPEC) isolated from dogs were screened and characterized for the genes encoding for the ESBLs, pAmpC, carbapenemases and PMQR genes by PCR and sequencing. Phylogenetic groups, virulence gene profiles and multilocus sequence typing (MLST) were used to investigate the genetic background of the ESC-R E. coli isolates.Results: Among 40 ESC-R E. coli, the predominant β-lactamase gene was blaCTX−Ms (n = 35), and followed by blaTEM−1 (n = 31), blaSHV−12 (n = 14), blaOXA−48 (n = 8), blaTEM−30 (n = 4), blaCMY−2 (n = 3) and blaDHA−1 (n = 2). The most common specific blaCTX−M gene subtype was blaCTX−M−15 (n = 31), and followed by blaCTX−M−123 (n = 14), blaCTX−M−1 (n = 10), blaCTX−M−14 (n = 10) and blaCTX−M−9 (n = 7). PMQR genes were detected in 32 (80%) isolates, and the predominant PMQR gene was aac(6′)-Ib-cr (n = 26), followed by qnrS (n = 12), qnrD (n = 9), qnrB (n = 8), qepA (n = 4), and all PMQR genes were detected in co-existence with β-lactamase genes. traT (n = 34) and fimH (n = 32) were the most prevalent virulence genes, and virulence genes fimH, iutA, fyuA, malX, iha, and sat were more prevalent in phylogenetic group B2. The 40 ESC-R isolates analyzed were assigned to 22 sequence types (STs), and the clonal lineages ST131 (n = 10) and ST10 (n = 9) were the predominant STs.Conclusion: High prevalence of β-lantamases and PMQR genes were detected among ESC-R E. coli from companion animals. This is also the first description of the co-existence of six β-lantamase genes and five PMQR genes in one E. coli isolate. Moreover, 10 ST131 clones harboring CTX-M-15 were detected.

Staphylococcus aureus is a well-known colonizer and cause of infection among animals and it has been described from numerous domestic and wild animal species. The aim of the present study was to investigate the molecular epidemiology of S. aureus in a convenience sample of European wildlife and to review what previously has been observed in the subject field. 124 S. aureus isolates were collected from wildlife in Germany, Austria and Sweden; they were characterized by DNA microarray hybridization and, for isolates with novel hybridization patterns, by multilocus sequence typing (MLST). The isolates were assigned to 29 clonal complexes and singleton sequence types (CC1, CC5, CC6, CC7, CC8, CC9, CC12, CC15, CC22, CC25, CC30, CC49, CC59, CC88, CC97, CC130, CC133, CC398, ST425, CC599, CC692, CC707, ST890, CC1956, ST2425, CC2671, ST2691, CC2767 and ST2963), some of which (ST2425, ST2691, ST2963) were not described previously. Resistance rates in wildlife strains were rather low and mecA-MRSA isolates were rare (n = 6). mecC-MRSA (n = 8) were identified from a fox, a fallow deer, hares and hedgehogs. The common cattle-associated lineages CC479 and CC705 were not detected in wildlife in the present study while, in contrast, a third common cattle lineage, CC97, was found to be common among cervids. No Staphylococcus argenteus or Staphylococcus schweitzeri-like isolates were found. Systematic studies are required to monitor the possible transmission of human- and livestock-associated S. aureus/MRSA to wildlife and vice versa as well as the possible transmission, by unprotected contact to animals. The prevalence of S. aureus/MRSA in wildlife as well as its population structures in different wildlife host species warrants further investigation.
