title: A colibacillosis outbreak in farmed red-legged partridges (Alectoris rufa).
abstract: Colibacillosis in different forms is responsible for significant economic losses in the poultry industry worldwide. Escherichia coli strains frequently implicated in poultry disease are designated as avian pathogenic E. coli (APEC). Natural infections and disease due to APEC have been described in wild birds, but not as yet in red-legged partridges. During an outbreak in an experimental partridge farm, 23 of 43 1-day-old chicks belonging to the same batch died. Putative APEC strains were detected and isolated both in cloacal swabs and in tissues originating from the same individuals and from different birds showing similar clinical signs. This is the first study that identifies APEC strains linked to a colibacillosis outbreak in farmed red-legged partridges, and also confirms the importance of farmed partridges as fecal carriers and potential spreaders of APEC.
