“…Similar results were observed in the state of Minas Gerais, where the presence of antibodies against B. burgdorferi was detected in 7.69% opossums (MONTANDON et al, 2014). Other studies in Brazil have reported humans and animals seropositive for B. burgdorferi (YOSHINARI et al, 2010;CORRADI et al, 2006;MADUREIRA et al, 2007;MONTANDON et al, 2014), demonstrating different prevalence rates in dispersed areas and showing that both domestic and wild animals are becoming infected with a closely related Borrelia spp., although the agents have never been isolated in Brazil. Our findings reinforce the probable presence of these agents in opossums in eight municipalities in the state of São Paulo and emphasize the need for further research into these pathogens in this study area, in view of the occurrence of BSF and BYS in humans in the state of São Paulo.…”

Evidência sorológica de exposição a agentes transmitidos por carrapatos em gambás (Didelphis spp.) AbstractThis work involved a serological investigation of tick-borne pathogens in opossums in eight municipalities of the state of São Paulo, Brazil. Serum samples from 109 opossums (91 Didelphis aurita and 18 Didelphis albiventris) were tested to detect antibodies to Rickettsia rickettsii (Taiaçu strain, 1:64 cut-off) and Ehrlichia canis (São Paulo strain, 1:40 cut-off), by indirect immunofluorescence assay (IFA); and against Borrelia burgdorferi (strain G39/40) by enzyme-linked immunosorbent assay (ELISA). The presence of antibodies to anti-R. rickettsii, anti-E. canis and anti-B. burgdorferi was detected in 32 (29.35%), 16 (14.67%) and 30 (27.52%) opossums, respectively. Opossum endpoint titers ranged from 64 to 1,024 for R. rickettsii, from 40 to 160 for E. canis, and from 400 to >51,200 for B. burgdorferi. These serological results suggest that opossums have been exposed to Rickettsia spp., Ehrlichia spp., and B. burgdorferi-related agents in the state of São Paulo. Our study underscores the need for further research about these agents in this study area, in view of the occurrence of Spotted Fever and Baggio-Yoshinari Syndrome disease in humans in the state of São Paulo, Brazil.

“…Domestic and wild animals act as reservoirs for the etiological agents for these diseases. For Lyme disease, tick acts as a vector for the etiological agent and human beings and as accidental hosts in the epidemiological cycle (Gill and Johnson, 1992; Macedo, 1997; Corradi et al , 2005; Langoni et al , 2008). …”

The aim of this study was to conduct a serological survey for Lyme diseases, brucellosis, leptospirosis and toxoplasmosis and identify the risk variables related to these zoonoses in humans living in the rural area of Jataizinho, state of Parana, Brazil. A total of 63 rural properties were surveyed. Additionally, 207 serum samples collected from these rural area inhabitants were tested for indirect immunofluorescence (IFI) and western blots (WB) were performed to detect Borrelia burgdorferi (sensu lato); a tamponated acidified antigen test (AAT) and 2-mercaptoethanol (2-ME) were used to detect antibodies of Brucella abortus; the microscopic agglutination test (MAT) was carried out to detect antibodies anti-Leptospira spp. and IFI was used to find antibodies of Toxoplasma gondii. Two of the samples (0.96%) were reactive for Lyme borreliosis, three (1.4%) for brucellosis, 25 (12.1%) for leptospirosis and 143 (69.1%) for toxoplasmosis. Although the town of Jataizinho has a human development index (IDH) that was considered to be average (0.733) in the state of Parana, the low social, economic and cultural conditions of the population from small rural properties have resulted in lack of basic information on animal health and direct or indirect contact with the various species of domestic animals, wildlife and ticks have probably contributed to the prevalence levels found. These results show the need for additional regional studies in order to determine the epidemiological characteristics of these diseases as well as their respective vectors and reservoirs so that effective prophylaxis can be administered in the human population.

“…Tanto carrapatos quanto ninfas (em menor extensão), são responsáveis pela transmissão, uma vez que adquirem a bactéria durante a alimentação em qualquer um dos estágios intermediários, com a persistência da bactéria até a evolução ao próximo estágio do artrópode, a chamada transmissão transestadial (Seixas et al, 2011). Em raros casos, ou experimentalmente, são transmitidas por tabanídeos, culicídeos e sifonápteros (Corradi, 2006;Soares et al, 2000). Os carrapatos se infectam durante o repasto sanguíneo em animais portadores da bactéria, e devem se alimentar por mais de 12 horas para transmitir a B. burgdorferi Shaw & Ihle, 1999).…”

A doença de Lyme é uma doença zoonótica, de distribuição mundial, causada por uma bactéria espiroqueta do gênero Borrelia burgdorferi sensu lato. É transmitida por carrapatos Ixodídeos durante seu repasto sanguíneo. Acomete diferentes espécies de animais silvestres, domésticos e também o homem, manifestando-se de forma multissistémica. Os mamíferos domésticos, apesar de em sua maioria serem assintomáticos, podem apresentar manifestações clínicas com quadros inespecíficos, como alterações articulares, letargia, anorexia, linfadenopatia e ainda alterações renais, cardíacas e neurológicas. Os cães são considerados como sentinelas da doença em humanos. O diagnóstico deve basear-se na sintomatologia clínica bem como em critérios epidemiológicos, e ser devidamente sustentado por testes sorológicos. O tratamento principal consiste na administração de antibioterapia, em especial as tetraciclinas, e antinflamatórios. Considera-se de suma importância a realização de profilaxia da borreliose através do controle de artrópodes vetores da bactéria.
