“…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.…”

Microdilution testing reveals considerable and diverse antimicrobial resistance of Escherichia coli, thermophilic Campylobacter spp. and Salmonella spp. isolated from wild birds present in urban areas

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.

“…To our knowledge, this has not been done before as existing studies from this geographic area are either limited to certain bird or bacteria species (Loncaric et al 2013;Dolejska et al 2007Dolejska et al , 2009. The data were analysed in regard to differences in the AMR profiles between E. coli, Campylobacter spp.…”

“…Ultimately, this may lead to colonization by microorganisms atypical of the natural habitats of wildlife species (Power et al 2013). Class I integrons reported in clinical pathogens are commonly identified in aquatic vertebrates, including gulls, flamingo, carp, salmon, and catfish, all animals frequently exposed to anthropogenic impact in their natural habitats (e.g., McIntosh et al 2008;Dolejska et al 2009). …”

ABSTRACT:Greater interaction between humans and wildlife populations poses significant risks of anthropogenic impact to natural ecosystems, especially in the marine environment. Understanding the spread of microorganisms at the marine interface is therefore important if we are to mitigate adverse effects on marine wildlife. We investigated the establishment of Escherichia coli in the endangered Australian sea lion (Neophoca cinerea) by comparing fecal isolation from wild and captive sea lion populations. Fecal samples were collected from wild colonies March 2009-September 2010 and from captive individuals March 2011-May 2013. Using molecular screening, we assigned a phylotype to E. coli isolates and determined the presence of integrons, mobile genetic elements that capture gene cassettes conferring resistance to antimicrobial agents common in fecal coliforms. Group B2 was the most abundant phylotype in all E. coli isolates (n537), with groups A, B1, and D also identified. Integrons were not observed in E. coli (n521) isolated from wild sea lions, but were identified in E. coli from captive animals (n516), from which class I integrases were detected in eight isolates. Sequencing of gene cassette arrays identified genes conferring resistance to streptomycin-spectinomycin (aadA1) and trimethoprim (dfrA17, dfrB4). Class II integrases were not detected in the E. coli isolates. The frequent detection in captive sea lions of E. coli with resistance genes commonly identified in human clinical cases suggests that conditions experienced in captivity may contribute to establishment. Identification of antibiotic resistance in the microbiota of Australian sea lions provides crucial information for disease management. Our data will inform conservation management strategies and provide a mechanism to monitor microorganism dissemination to sensitive pinniped populations.

“…Existen factores que pueden dar origen a falsos negativos debido a una baja concentración del agente en la muestra estudiada, ya que por lo general, esto induce a una gran difi cultad en su detección en los cultivos tradicionales 8 . La positividad a Salmonella en gaviotas detectada en este estudio fue superior a lo señalado en un estudio realizado en la ciudad de Lisboa en el año 2002 de heces de gaviotas patas amarillas (L. cachinnas) y gaviotas de dorso negro (L. fuscus) quienes reportaron una prevalencia del 13% 15 , y similar a un estudio realizado en la parte Noreste de República Checa en el año 2009 con una prevalencia de 24% en gaviotas de cabeza negra (L. ridibundus) a partir de torulado cloacal 16 . Si se considera que la gaviota dominicana es la especie más común en Chile, el 25,2% de gaviotas positivas o portadoras de especies de Salmonella, está indicando el importante rol que cumplirían éstas como diseminador de los serovares de Salmonella enterica tanto a humanos como animales.…”

Antibiotic-resistantSalmonellaandEscherichia coliisolates with integrons and extended-spectrum beta-lactamases in surface water and sympatric black-headed gulls

Abstract: Intensive contamination of pond surface water by antibiotic-resistant E. coli and salmonellae was documented. Black-headed gulls were identified as important reservoirs of antibiotic-resistant salmonellae and E. coli, including extended-spectrum beta-lactamase-producing isolates.
