“…In another study conducted in birds from Austria, a large sample was screened for MRSA. From the 1,325 samples of wild birds analyzed, only three MRSA were detected [129]. In a study conducted with 16 birds of prey (Buteo buteo, Strix aluco and Corvus corone), one S. aureus was found in a common buzzard.…”

“…The ability of S. aureus to acquire antibiotic resistances along with its zoonotic potential highlights the importance of studying this microorganism in other contexts, such as in free-living animals. Studies have detected and characterized S. aureus in different wild animals, such as, among others, in hares, deer, foxes, mice, mountain goats, kangaroos, hedgehogs, bears, wild boars, beavers, squirrels, shrews, bats, minks, raccoons, seals, apes, as well as in different species of birds [121][122][123][124][125][126][127][128][129][130].…”

Molecular Epidemiology of Staphylococcus aureus Lineages in Wild Animals in Europe: A Review

Staphylococcus aureus is an opportunist pathogen that is responsible for numerous types of infections. S. aureus is known for its ability to easily acquire antibiotic resistance determinants. Methicillin-resistant S. aureus (MRSA) is a leading cause of infections both in humans and animals and is usually associated with a multidrug-resistant profile. MRSA dissemination is increasing due to its capability of establishing new reservoirs and has been found in humans, animals and the environment. Despite the fact that the information on the incidence of MRSA in the environment and, in particular, in wild animals, is scarce, some studies have reported the presence of these strains among wildlife with no direct contact with antibiotics. This shows a possible transmission between species and, consequently, a public health concern. The aim of this review is to better understand the distribution, prevalence and molecular lineages of MRSA in European free-living animals.

“…The Micronaut test plates were inoculated with 100 μl per well and incubated for 18-24 h at 37°C (E. coli and Salmonella) or for 48 h at 41.5°C in a microaerobic atmosphere (Campylobacter). After The size of the dots corresponds to the number of wild birds sampled from these locations (Konicek et al, 2016) incubation, the plates were read out by a photometer and analysed by the MCN 6.0 software (MERLIN Diagnostika GmbH, Bornheim-Hersel, Germany). The minimal inhibitory concentrations and susceptibilities were determined according to CLSI guidelines (Clinical andLaboratory Standards Institute 2013, 2014).…”

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 occurrence of Campylobacter and Salmonella in aquatic environments (Levantesi et al, 2012;Pitk€ anen, 2013) and in wildlife reservoirs is well documented (Hilbert et al, 2012;Greig et al, 2015). A wide variety of birds, including raptors, waterfowl, crows, pigeons and gulls, have been reported as asymptomatic carriers of these zoonotic agents (Molina-Lopez et al, 2011;Gargiulo et al, 2014;Antilles et al, 2015;Jurado-Tarifa et al, 2016;Konicek et al, 2016), with their risk of infection linked to their opportunistic feeding habits and their proximity to farms or livestock pastures (Ramos et al, 2010;Hald et al, 2016). Although some Campylobacter and Salmonella strains display an important host-specificity (Heithoff et al, 2008;Griekspoor et al, 2013), many strains or serovars infectious to humans are adapted to a generalist lifestyle (e.g., certain C. jejuni and C. coli strains or Salmonella serovars Typhimurium and Enteritidis) and have a broad-host range (Hoelzer et al, 2011;Dearlove et al, 2016).…”

Zoonotic thermophilic Campylobacter and nontyphoidal Salmonella enterica are a major cause of foodborne human gastroenteritis worldwide. There is little information about reservoirs of these zoonotic agents in Africa. Thus, chicks of kelp gulls (Larus dominicanus, n = 129) and greater crested terns (Thalasseus bergii, n = 100) were studied at five colonies on the Western Cape coast (South Africa) during summer 2013/2014. Campylobacter spp. occurrence was 14.0% (CI : 9.9-19.3), with C. jejuni the most frequently isolated species, whilst that of Salmonella was 27.5% (CI : 21.9-33.9) overall, with a higher prevalence in gulls (43.0%, CI : 34.8-52.4) than terns (7.0%, CI : 3.1-14.4). Among the 16 different S. enterica serovars found, Anatum, Enteritidis and Hadar were the most frequent. The same or highly similar pulsed-field gel electrophoresis genotype was found in some Salmonella isolates from seabirds and humans presenting with salmonellosis in Cape Town hospitals. Both Campylobacter and Salmonella isolates exhibited antimicrobial resistance to several agents, including critically important antimicrobials (quinolones, tetracyclines and β-lactams) and multidrug resistance in Salmonella serovars from kelp gulls. Our results highlight the importance of seabirds as reservoirs of Campylobacter and Salmonella resistant strains and their role in the maintenance and transmission of these bacteria in the environment, with implications for public health.
