Abstract
Gulls, as migratory wild birds are known to spread different pathogens over long distances. The aim of this study was to access the prevalence of different Listeria species in a gull population feeding at a landfill in Zagreb. In total, 390 gulls of three species were sampled: Yellow-legged Gull, Larus michahellis; Black-headed Gull, L. ridibundus and Common Gull, L. canus. The most prevalent species was Listeria innocua (14.4%), while L. monocytogenes was found in 11.3% of tested samples. Other species were present in a smaller percentage; L. welshimeri (1.3%), L. ivanovii (0.5%) and L. seeligeri (0.3%). Serotyping of L. monocytogenes isolates was performed using molecular and conventional methods, and most isolates belonged to the 1/2a and 1/2b serotypes. To the best of our knowledge, this is the first report of the presence of L. monocytogenes and other Listeria spp. in wild birds in Croatia.
