    Abstract

    Several studies have shown that migratory birds play an important role in the ecology, circulation anddissemination of pathogenic organisms. In October 2006, a health status evaluation was performed on alarge population of migratory birds passing through the territory of Ustica (Italy), an island located on themigration route of many species of birds to Africa, and various laboratory tests were conducted. In total,218 faecal swabs and the internal organs of 21 subjects found dead in nets were collected for bacteriologicaland virological examination, including avian influenza and Newcastle disease. In addition, 19 pooled freshfaecal samples were collected for mycological examination. The bacteriological analysis produced 183 strainsbelonging to 28 different species of the Enterobacteriaceae family. In particular, Salmonella bongori, Yersiniaenterocolitica and Klebsiella pneumonia strains were isolated. Almost all of the isolates were susceptible tosulphamethoxazole/trimethoprime (99.4%), cefotaxime (98.9%), nalidixic acid (96.7%), chloramphenicol(95.6%), and tetracycline (93.4%). Alternatively, many strains were resistant to ampicillin (42.6%),amoxicillin-clavulanic acid (42.6%), and streptomycin (43.7%). According to reverse transcriptasepolymerasechain reaction analysis, all of the samples were negative for the M gene of avian influenzavirus. Moreover, isolation tests conducted on specific pathogen free eggs were negative for avian influenzaand Newcastle disease. Several hyphomycetes and yeasts belonging to different genera were present in thespecimens, and Cryptococcus neoformans was observed in a pooled faecal sample. Antibiotic resistance inwildlife can be monitored to evaluate the impact of anthropic pressure. Furthermore, migratory birds arepotential reservoirs of pathogenic agents; thus, they can be regarded as sentinel species and used asenvironmental health indicators.
