The objective of this study was to carry out a microbiological and molecular research of Streptococcus equi subspecies equi in the Rio Branco micro-region, Acre, Brazil, as well as to assess the risk factors. Sixty-four horses were submitted to clinical evaluation, from which nasal secretion samples were collected for bacteriological culture. The isolates were submitted to DNA extraction and PCR. The risk factors were verified through epidemiological questionnaires. It was verified that 32.8% (21/64) of the animals presented clinical signs suggestive. In the PCR, 50 (78.1%) samples were phenotypically compatible to genus, but none of them showed amplification of the 16SrRNA gene. The lack of disinfection of facilities and vaccination were the most frequent risk factors. It was concluded that Streptococcus equi subspecies equi is not present in the studied population, however, it may be susceptible to the disease due to the lack of sanitary criteria in the breeding.Keywords: Strangles; epidemiological study; Western Amazonia.
