[Mortality in free living siskins (Spinus spinus Linnaeus, 1758) due to Salmonella typhimurium, phage type DT104 and DT013].
This report deals with an enzootic due to Salmonella Typhimurium in two free living Eurasian siskins (Spinus spinus Linnaeus, 1758). Other birds in the vicinity of the siskins were not affected. Clinical signs consisted of non-specific symptoms such as ruffled plumage, apathy and reduced food intake. During necropsy, gross lesions were enlarged livers with focal necrosis, pale spleens, enlarged kidneys, pneumonia and enteritis. Salmonella Typhimurium was isolated from internal organs in pure culture. Using the polymerase chain reaction, the detection of Salmonella according to EN ISO 6579:2002 was confirmed. The detailed characterisation of both isolates in the Federal Institute for Risk Assessment and in the Robert Koch Institute yielded for the first siskin Salmonella Typhimurium, 4, 5, 12: i : 1, 2, LT DT104, BT a and for the second siskin Salmonella Typhimurium, 4,12 i : 1, 2, LT DT013, BT c. These phage types were identified for the first time in siskins. The detected phage types have importance as causes of disease not only for free living siskins but also as infectious and zoonotic agents for domestic poultry and poultry products.
