The hoary fox (Pseudalopex vetulus) is a wild canid native to Brazil and is commonly found in the semiarid northeastern area living in contact with cattle. The main purpose of this study was to investigate the presence of Neospora caninum and Toxoplasma gondii DNA in hoary foxes, in the state of Paraiba, Brazil. Brain tissue samples were collected from 49 hoary foxes. From the samples, DNA extraction and the polymerase chain reaction (PCR) were performed using specific primers for N. caninum and T. gondii. The prevalences found were 14.3% (7/49) for T. gondii and 12.2% (6/49) for N. caninum. The molecular identities of the amplified products were confirmed by means of the sequencing reaction. This study demonstrated the presence of N. caninum and T. gondii DNA in free-ranging hoary foxes in Brazil for the first time, thus confirming that this species is an intermediate host.
