title: [An attempt to determine intermediate hosts of the tapeworm Echinococcus multilocularis in Poland].
abstract: Echinococcus multilocularis, a tiny tapeworm (2-3 mm in length) occurs in the small intestine of red foxes and raccoon dogs in Poland. Small rodents, intermediate hosts of the tapeworm can ingest parasite eggs excreted in faeces by final host. Humans can become infected by accidental ingestion of the eggs. The resulting disease, alveolar echinococcosis, potentially lethal zoonosis, typically presents as an infiltrative tumor-like growth in the liver, which may invade neighbouring organs. The objective of the study was to determine intermediate host species for E. multilocularis in Poland. During the years 2004-2006, a total of 1425 animals, i.e. 1170 rodents (14 species), 238 insectivores (4 species) and 17 Mustelids (3 species) were trapped and autopsied for the presence of E. multilocularis protoscolices (larvae). Animals were captured in northern, north-eastern, central and southern Poland, areas where the high prevalence of the tapeworm was recorded in foxes. In 44 (3.1%) of examined animals were found cysts in the liver, however no typical lesions were affirmed. Infection was not confirmed using PCR technique with primers specific for E. multilocularis (EmCA90, EmTriple83).
