Borrelia burgdorferi sensu lato in humans in a rural area of Paraná State, Brazil

  • Authors: Carreira T, Freitas JC, Gonçalves D, Moura RA, Nunes M, Vidotto O, Vieira ML
  • Publication Year: 2015
  • Journal: Brazilian Journal of Microbiology
  • Link: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822015000200571

This study describes the detection of Borrelia garinii and Borrelia burgdorferi sensu stricto (s.s.) in Brazilian individuals using PCR and DNA sequencing. Our results suggest that these species are emerging pathogens in this country, and additional studies are necessary to determine the epidemiological characteristics of this disease in Brazil.

First record of Borrelia burgdorferi B31 strain in Dermacentor nitens ticks in the northern region of Parana (Brazil)

  • Authors: Benitez A, Carreira T, Freitas JC, Gonçalves DD, Lopes-Mori FMR, Nunes N, Vidotto O, Vieira ML
  • Journal: Brazilian Journal of Microbiology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/24516456

The aim of this study was to investigate the presence of DNA of Borrelia burgdorferi sensu lato (s.l.) in ticks that feed on horses used for animal traction in rural Jataizinho, Parana, Brazil. Between February and June 2008, a total of 224 ticks was collected of which 75% were identified as Dermacentor nitens and 25% as Amblyomma cajenense.
