“…Beauveria bassiana is a bacterium that produces bacteriocin inhibitory to pathogenic bacteria such as Listeria (Siragusa and Cutter 1993), which is was not isolated here but is prevalent in wild birds (Hellström et al 2008). Accordingly, B. campestris might be beneficial to birds in the same way as E. faecium (Moreno et al 2003) albeit via a different causal mechanism (toxin regulation rather than out-competition).…”

PLEASE SCROLL DOWN FOR TEXT. Microbial relationships between birds and nesting environments are complex and remain poorly understood. Past studies have focused on between-nest variation in egg/chick bacterial profiles with little attention given to the microbial relationships between adult birds and their nests. Moreover, very little microbial research has included mycology despite fungi being prevalent in nesting environments and important correlates of fitness in chicks. In this study, we identified microbes associated with feathers, skin and nests of Pied Flycatchers Ficedula hypoleuca, an internationally-declining migrant songbird. From 75 samples, we isolated 50 bacterial OTUs (Operational Taxonomic Units; dominated by Enterococcus, Sanguibacter, Pseduomonas) and 63 fungal OTUs (dominated by Penicillium, Aspergillus), many of which had not previously been isolated from birds. Although females had significantly higher non-haemolytic bacterial OTU richness and males significantly higher fungal OTU richness, there was considerable diversity in actual OTUs isolated and thus there was no "typical" female, male, or nest microbial profile. Interestingly though, we show for the first time that the microflora of individual females is significantly more similar the microflora of her own nest than the site-level average of all nests. This suggests microbes are shared within female-nest pairs such that microbial communities start to converge. This is probably a two-way interaction as gut/skin microbes were isolated from nests and plant/soil microbes were isolated from females. Convergence was not seen for males, which probably reflects the role of the female as sole nest builder and egg incubator in this species. We discuss these findings in relation to microbial transfer pathways and avian nesting behaviour. The avian origins of some nest microbes, and species-specific differences in material used to construct nests, means that it is not surprising that there is considerable interspecific variation in nest microflora. This has been demonstrated in direct comparative studies by Goodenough and Stallwood (2010) and Peralta-Sánchez et al (2012), and is also evident by comparing single-species studies by...

“…In the present study, we could not detect Listeria species and L. monocytogenes in broiler-layer chickens, sparrows, Indian mynah, duck, turkey, guinea fowl and lovebirds. Earlier, L. monocytogenes was isolated from 36% faecal samples from wild birds of Helsinki region 6 and the most common serotypes detected were 1/2a, followed by 4b and 1/2b. Healthy wild birds were found to carry L. monocytogenes in their intestinal contents with higher prevalence of L. monocytogenes at a landfill site than in urban areas 6 .…”

“…Even though several studies have demonstrated broader distribution of Listeria species throughout the natural environment, the role of wild animals and birds in the ecology and as reservoirs of L. monocytogenes is not clearly understood 3 . Limited studies on the detection of pathogenic bacteria including L. monocytogenes from wild animals and birds have been documented [4][5][6][7] . Studies on the detection of Listeria from sources other than foodprocessing environments may help reveal the population genetics and natural history of Listeria species 8 .…”

“…The detection of virulent strains of 4b serogroup in barking deer (Muntiacus muntjak), porcupine (Hystrix indica), pigeon (Columba livia) and crow (Corvus splendens) is a cause of concern. Prevalence of L. monocytogenes in captive wild animals 4,23,24 and bird species 4,6,25 has been studied earlier worldwide. Recently, the red deer has been reported to excrete L. monocytogenes and other zoonotic pathogens in the environment in Europe 26 .…”

Background Listeria monocytogenes (Lm) present in farming soil and food‐processing facilities threatens food safety, but little is known about the carriage of Lm by wildlife. Objectives We estimated the prevalence of faecal Lm shedding among wildlife admitted to a veterinary medical teaching hospital in central New York and characterized a subset of the Lm isolates. Methods Wildlife samples were collected between May 2018 and December 2019. We characterized the Lm isolates by assessing the growth at three temperatures approximating the body temperatures of reptiles (25°C), mammals (37°C), and birds (42°C) and identifying genotypic characteristics related to transmission and virulence. Results The apparent prevalence of faecal Lm shedding was 5.6% [18/324; 95% confidence interval (CI), 3.3%–8.6%]. Among 13 isolates that represented two lineages and 11 clonal complexes, three and five isolates were grouped into the same SNP clusters with human clinical isolates and environmental isolates, respectively. However, specific SNP difference data showed that Lm from wildlife was generally not closely related (>22 SNP differences) to Lm from human clinical sources and the food‐processing environment. While the stress response locus SSI‐2 was absent, SSI‐1 was found in four isolates. Virulence genes prfA, plcA, hly, mpl, actA, plcB, inlA, inlB, inlC, inlE, inlH, inlJ, and inlK were present, without any premature stop codons, in all isolates. Virulence loci Listeria pathogenicity island 3 (LIPI‐3) and LIPI‐4, which have been linked to hypervirulence, and inlG were found in four, three, and seven isolates, respectively. Conclusions Wildlife represents a potential reservoir for genetically diverse and putatively hypervirulent Lm strains. No statistically significant association between growth parameters and hosts was observed. However, compared to lineage I isolates, lineage II isolates showed significantly (p < 0.05) faster growth at 25°C and significantly slower growth at 42°C, suggesting that wildlife Lm isolates that belong to lineages I and II differ in their ability to grow at 25°C and 42°C.
