“…The frequency of seropositive buffaloes in the present work (83.9%) was markedly greater than the rate of 54.9% observed among cattle (GUEDES JUNIOR et al, 2008) and the 26.7% found among horses (GALO et al, 2009), in the same region. These differences in frequencies of seropositive animals may be connected with greater susceptibility among buffaloes and with the intrinsic immunological factors of each animal species.…”

Detection of anti-Borrelia burgdorferi antibodies in buffaloes (Bubalus bubalis) in the state of Pará, Brazil AbstractThis study aimed to investigate the frequency of homologous antibodies of IgG class against Borrelia burgdorferi in buffaloes in the state of Pará, Brazil. Blood serum samples from 491 buffaloes were analyzed by means of the indirect ELISA test, using crude antigen produced from a cultivar of the North American strain G39/40 of B. burgdorferi. There were 412 positive samples (83.91%), and there was no statistically significant difference in the proportions of positive animals between the 81.69% (232/284) originating from Marajó Island and the 86.96% (180/207) from the continental area of the state of Pará. In all the municipalities studied, the frequency of positive findings of antibodies against B. burgdorferi among the animals ranged from 63.6% to 92.9%. The high numbers of seropositive animals can be explained by the frequent presence of the tick Rhipicephalus (Boophilus) microplus, and by the possible existence of spirochetes of the genus Borrelia infecting buffaloes in the region studied, although specific studies are needed to confirm this relationship. These factors suggest that a cross-reaction exists between the North American strain G39/40 of B. burgdorferi, which is used as an antigenic substrate, and the species of Borrelia spp. that possibly infects buffaloes in the state of Pará.Keywords: Buffaloes, Borrelia spp., epidemiology, serology. ResumoEste estudo teve como objetivo investigar a frequência de anticorpos homólogos da classe IgG contra Borrelia burgdorferi em búfalos do estado do Pará. Amostras de soro de 491 búfalos foram analisadas por meio do teste ELISA indireto, utilizando antígeno bruto produzido a partir do cultivo da cepa norte americana G39/40 de B. burgdorferi. Foram encontrados 412 soros positivos (83,91%), não havendo diferença estatística significativa entre os 81,69% (232/284) animais positivos provenientes da Ilha de Marajó e os 86,96% (180/207) da base continental do estado do Pará. Em todos os municípios estudados os animais apresentaram frequência de anticorpos contra B. burgdorferi, com positividade variando de 63,6% a 92,9%. O alto número de soropositivos pode ser explicado pela frequente presença do carrapato Rhipicephalus (Boophilus) microplus e pela possível existência de espiroquetas do gênero Borrelia infectando búfalo na região estudada, embora novos estudos sejam necessários para a confirmação desta relação. Estes fatos sugerem reação cruzada entre a cepa americana G39/40 de B. burgdorferi utilizada como substrato antigênico e a espécie de Borrelia spp. que possivelmente infecta bubalinos no estado do Pará.

“…Guedes Junior et al (2008) found 54.9% (135/246) cattle positives to homologues antibodies to B. burgdorferi. (GALO et al, 2009), found 26,7% (80/300) horses positives to homologues antibodies to B. burgdorferi, both in the same region. On the basis of this finding, the current study aimed to evaluate the frequency of homologous anti-B.…”

“…Lyme borreliosis presents several clinical pictures, particularly, in humans (Yoshinari et al , 1993b; Galo, 2006). In Brazil, this disease was first reported in serologic studies in humans by Yoshinari et al (1993a) and in animals by Fonseca and collaborators (Fonseca et al , 1994).…”

“…Both genera are known vectors of Borrelia spirochetes. In fact, several studies carried out in animals in the states of Rio de Janeiro and Pará have reported the presence of antibodies against B. burgdorferi s.l., as well as the isolation of this spirochete from Boophilus microplus ticks (Salles et al , 2002; Galo, 2006; Madureira, 2007). …”

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. To amplify B. burgdorferi s.l. DNA, the intergenic space region (ISR) between the 5S (rrf) 23S (rrl) rRNA genes was used as targets for nested-PCR. Two ticks of the D. nitens species were positive for B. burgdorferi s.l. Both species showed a fragment of 184 bp, but the sequencing revealed 99.9% homology with the B. burgdorferi sensu stricto (s.s.) strain B31. These results showed, for the first time, the presence of spirochete DNA infecting ticks that parasitize horses used for animal traction, in the rural municipality mentioned. In conclusion, this study opens up promising prospects for determining the infection rate of B. burgdorferi s.s. genospecies or other species in the equine population, as well as the impact of the infection rate on Lyme disease in the state of Parana.

Borreliosis caused by Borrelia burgdorferi sensu lato is a cosmopolitan zoonosis studied worldwide; it is called Lyme disease in many countries of the Northern Hemisphere and Lyme-like or Baggio-Yoshinari Syndrome in Brazil. However, despite the increasing number of suspect cases, this disease is still neglected in Brazil by the medical and veterinary communities. Brazilian Lyme-like borreliosis likely involves capybaras as reservoirs and Amblyomma and Rhipicephalus ticks as vectors. Thus, domestic animals can serve as key carriers in pathogen dissemination. This zoonosis has been little studied in horses in Brazil. The first survey was performed in the state of Rio de Janeiro, and this Brazilian Borreliosis exhibits many differences from the disease widely described in the Northern Hemisphere. The etiological agent shows different morphological and genetic characteristics, the disease has a higher recurrence rate after treatment with antibiotics, and the pathogen stimulates intense symptoms such as a broader immune response in humans. Additionally, the Brazilian zoonosis is not transmitted by the Ixodes ricinus complex. With respect to clinical manifestations, Baggio-Yoshinari Syndrome has been reported to cause neurological, cardiac, ophthalmic, muscle, and joint alterations in humans. These symptoms can possibly occur in horses. Here, we present a current panel of studies involving the disease in humans and equines, particularly in Brazil.
