The purpcses of the study were to identify the microorganisms carrierl by migratory birds and to evalua the impact of these icroorganisms to poultry industry. In virus aspect, a total of 1,820 of fecal samples from wild birds were examirJ. Pu ken stains of Al viruses weieisolaelandas H1N1, H2NZ H3N8, H4NE, HTN3, and H1ON8 serotypa were kientifiM. Four stains of paramyxovinis and one stain of PM Vi (MDV) were isolatol. Fortunaeiy, all of these stains were low or none pathogenic, In bacterialaspect, typeCtotulism, oneofthemajorcauses ofdeathofvii]dbirds in Taiwan, was confirmerl in three cases. In parasite aspat, one cxxcidian, three nematcdes (Porrccaecum sp. Strongyloides sp. Capillaria sp.), one throny-hearbi worm (&hinorhynchus sp.) were rii. However, all the parasites found in migration birds exist in domestic birds. It is worthy of exploring that cpuld the parasites he sibly tansmitoi each other? In conclusion, the microorganisms isolaiM from migratory birds were low or none pathogenic to domestic poultry in Taiwan. In the view of epidemiology of API, summer visitors of migratory birds might have higher gohebility to carry pathogens, so it could not he exdu that the pdability of migratory birds carrying high pathogens next year. Therefore, it is ressary to continue the surveillance program for migratory birds.
