[Detection of Brachyspira pilosicoli and other Brachyspira species in Argentine poultry farms]

Abstract

Some species of the genus Brachyspira such as Brachyspira pilosicoli, Brachyspira intermedia and Brachyspira alvinipulli are pathogenic species capable of producing disease in laying hens. In our country, the presence of B. pilosicoli and other species of Brachyspira has been reported in pigs and dogs but there is no record of their presence in poultry. Fecal and cecal content samples from 34 laying hens of 4, 12 and 24 months of age from two farms were analyzed by isolation, biochemical tests and PCR. B. pilosicoli and Brachyspira spp. were identified in samples taken from laying hens of 12 and 24 months of age.
