Abstract
Arcobacter butzleri isolation from chicken carcasses in Costa Rica is reported for the first time. The isolated strains (P and R) were presumptively identified by their phenotypic characteristics. Definitive identification was made using a multiplex PCR assay for the simultaneous detection and identification of Arcobacter butzleri, Arcobacter cryaerophilus and Arcobacter skirrowii. These first isolations indicate the necessity of further investigation about the prevalence, distribution, ecology and interactions with human beings of this and other Arcobacter species.
