title: Salmonella spp. as a cause of mortality and clinical symptoms in free-living garden bird species in Poland.
abstract: Some species of garden birds are considered to be sensitive to Salmonella (S.) spp. infections. The aim of this study was to determine the cause of mortality of six free-living birds in one private property in suburban area of Wrocław (Poland). In 2013 Poland experienced prolonged winter, with low temperatures and snow precipitations. During March and April, two dead individuals of the Eurasian siskin (Carduelis spinus) and four dead individuals of the Greenfinch (Carduelis chloris) were found in proximity of the bird feeder. At the time of ringing procedure in the same area, faecal samples of all individuals belonging to these two species of birds were collected, regardless clinical symptoms. In total, twenty two faecal samples of birds belonging to both bird species were collected in the same property. All of them were Salmonella enterica subsp. enterica serovar Typhimurium positive. The visible illness among European siskins and Greenfinches, caused by S. Typhimurium, sug- gests that both Eurasian siskin and Greenfinch may be potential reservoirs of Salmonella spp. Therefore they might play a role in transmission of zoonotic pathogens to other garden bird species or to people.
