Several species of intestinal spirochaetes, Brachyspira (B.) alvinipulli, B. intermedia and B. pilosicoli, may cause reduced egg production and faecal staining of eggshells in chickens. The aim of this study was to characterize potentially pathogenic and presumably non-pathogenic Brachyspira spp. from commercial laying hens. Selective culture, phenotyping, PCR and 16S rRNA gene sequencing were used and clinical data were collected. Phenotypic profiles were obtained for 489 isolates and 351… CONTINUE READING
