The disease occurred in 93 farms affecting 229 equids with a case fatality rate of 72.92%. Main clinical signs were circling, depression or hyperexcitability, ataxia, and progressive paralysis with a clinical manifestation period of 3\u201315 days. Main histologic lesions were a diffuse lymphocytic encephalomyelitis with neuronal death, satellitosis, neuronophagia, and hemorrhages being more severe in the cerebral gray matter of the telencephalon, diencephalon, and mesencephalon. Some animals also had areas of malacia in the telencephalon, thalamus, and basal nuclei. From 1 case, the virus was isolated by mice inoculation, and in other 13 cases was identified as Eastern equine encephalitis virus by semi-nested reverse transcription polymerase chain reaction. After DNA sequencing, all samples were identified as eastern equine encephalitis through the BLASTn analysis, but samples from the Cear\u00e1 and Para\u00edba states corresponded to the same cluster, while the sample from the state of Pernambuco corresponded to a different cluster.<\/jats:p>","DOI":"10.1177\/1040638711403414","type":"journal-article","created":{"date-parts":[[2011,5,12]],"date-time":"2011-05-12T16:29:05Z","timestamp":1305217745000},"page":"570-575","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":38,"title":["Outbreaks of Eastern equine encephalitis in northeastern Brazil"],"prefix":"10.1177","volume":"23","author":[{"given":"Maria L.
