%X The Dominican Republic (DR) and Haiti share the island of Hispaniola, and reportable transboundary animal diseases have been introduced between the two countries historically. Outbreaks of severe teschovirus encephalomyelitis in pigs began occurring in Haiti in February 2009, and a field and laboratort study in April 2010 indicated that the teschovirus disease is prevalent in many regions in Haiti including areas near the border with DR and that other viral disease agents, including CSF virus (CSFV), porcine circovirus type 2 (PCV-2), porcine reproductive and respiratory syndrome virus (PRRSV), and swine influenza virus (SIV), are present in the swine population in these regions. The purpose of this study was to evaluate the introduction of teschovirus encephalomyelitis from Haiti to DR and to identify the other viral disease agents present in the swine population in regions of DR near the border with Haiti. Six of 7 brains and 6 of 7 spinal cords collected from pigs with central nervous system (CNS) signs were positive in reverse transcription-polymerase chain reaction for PTV. Genome sequencing on the Dominican PTV and phylogenetic analysis on the polyprotein of PTV strains indicate that the sequence of the Dominican PTV is 99.1% identical to the Haitian isolate and closely related to other PTV-1 strains in the world. Among 109 serum samples tested, 65 (59.6%) were positive for antibodies to PCV-2, and 51 (46.8%) were positive for antibodies to CSFV. Fifty-four of the 109 serum samples were tested for antibodies to other agents. Among the 54 samples, 20 (37.0%) were seropositive to PTV-1, 17 (31.5%) tested seropositive to SIV H3N2, 12 (22.2%) were seropositive to SIV H1N1, and 1 (1.9%) was seropositive to PRRSV. 1. Introduction The Dominican Republic (DR) and Haiti share the island of Hispaniola, the second largest island in the Caribbean. Historically, reportable transboundary animal diseases have been introduced between the two countries. In 1978, an outbreak of African swine fever (ASF) was detected in DR, and the source of the outbreak was potentially linked to food waste from an airport that was fed to swine [1]. In order to prevent the introduction of the disease, the Haitian government ordered a preventive slaughter of all swine in a 15-km area along the border with DR [1]. Despite this effort, ASF was detected in Haiti and spread rapidly throughout the country in late 1978 [1]. ASF along with classical swine fever (CSF), which had been endemic there since about 1920, were both eradicated by the slaughter of the entire swine population in the
