“…In this study, a higher frequency of T. equi infection was observed in comparison with B. caballi infection corroborating the findings of previous studies on EP carried out in different regions of the world (BRÜNING, 1996;HEIM et al, 2007;RIBEIRO et al, 2013). Since the ticks Rhipicephalus microplus (BATTSETSEG et al, 2002), Amblyoma cajennense (= A.sculptum) (KERBER et al, 2009;MARTINS et al, 2016), and Dermacentor nitens (HEIM et al, 2007;SANTOS et al, 2009), which are the vectors of both T. equi and B. caballi, were present in the study area, differences in infection frequency between these two hemoparasitic infections is probably associated with the different forms of transmission and increased pathogenicity of T. equi (ALLSOPP et al, 2007), leading to higher and more persistent parasitaemias (DAVITKOV et al, 2016). In addition, the ability of equids to limit B. caballi infection (WEILAND, 1986) and/or the lower prevalence of B. caballi in the region (HAWKINS et al, 2015;ODUORI et al, 2015) may also explain the variations between the results of different surveys.…”

The aim of this study was to determine the frequency and factors associated to Babesia caballi, Theileria equi and Trypanosoma evansi in naturally infected equids from the northeast Brazil. Blood samples from 569 equids (528 horses, 8 mules, and 33 donkeys) were collected and tested for the presence of DNA of each of these protozoan parasites by PCR. Generalized linear models were used to evaluate risk factors associated with the infection. The frequency of T. equi infection was 83.5% (475/569) - 84.3% in horses, and 73.2% in donkeys and mules. The results of the final model indicated that age (senior group) and animal species (mule and donkey group) were protective factors against this pathogen. The frequency of B. caballi infection was 24.3% (138/569) - 23.5% in horses and 34.1% in donkeys and mules. Age (adult and senior group) was considered a protective factor against B. caballi infection whereas animal species (donkey and mule group) were considered a risk factor for the infection. Trypanosoma evansi infection was not detected in any of animals. Our results suggest that equids from the area studied may be infected earlier in life with the etiological agents of equine piroplasmosis and become asymptomatic carriers.

Objective: to develop and validate an interactive educational technology on spotted fever, to offer an innovative teaching method. Method: a methodological study that covered the following stages: analysis and diagnosis; instructional planning, didactic design, review, and validation and production of technology. Results: the analysis and diagnosis were obtained from experiences in education and health activities for spotted fever. In the instructional planning, it was defined that the technology would be presented in the form of an Interactive Laboratory, with learning stations. The production of the Laboratory was carried out by a multidisciplinary team made up of a carpenter, an electrician, and a plastic artist, among others. The review and validation process was subdivided into two stages: appearance and content validation by professionals in the fields of biology, and education and semantic validation by students of the Nursing and Pedagogy courses. The results of the appearance and content validation showed a content validity index over 0.8 for the vast majority of the variables. In the semantic validation, the Laboratory was evaluated positively by the students. Conclusion: the trajectory followed for the construction of the Interactive Laboratory on spotted fever gave academic and scientific support to the product, offering an innovative educational resource with pedagogical potential that values significant learning.

“…As capivaras e os cavalos assumem grande importância na cadeia epidemiológica da enfermidade, pois são os principais reservatórios e amplificadores dos carrapatos transmissores da FMB. Os animais mantidos em pastos sujos, com vegetação alta, ou em matas ciliares, encontram um ambiente bastante propício para a infestação pelo A. sculptum, tornando-se um grave problema de saúde ambiental e pública (11,18,26,27,28,29).…”

“…A picada do adulto, por ser dolorida, prontamente é percebida, e pode-se retirar o carrapato a tempo de não transmitir a doença. Outra forma de contágio se dá pelo esmagamento do carrapato quando é retirado, liberando seu conteúdo gástrico (9, 33) O período de incubação é de 2 a 14 dias com média de 7 dias e por meio das vias linfática e hematogênica, ocorre disseminação das riquétsias por todo organismo, com invasão de células endoteliais de pequenos e médios vasos de todo organismo, onde se multiplicam e disseminam-se (7,18).…”

A Febre Maculosa Brasileira (FMB) é uma zoonose, febril aguda, de gravidade variável, que geralmente se desenvolve em caráter endêmico, com distribuição mundial, causada por bactérias da família Rickettsiaceae, denominadas Rickettsia rickettsii, Rickettsia sp. cepa Mata Atlântica e Rickettsia parkeri (1, 2, 3). O presente estudo foi delineado com o objetivo de realizar uma revisão sistemática da literatura acerca dos aspectos epidemiológicos da febre maculosa brasileira, entre estudos empíricos publicados em periódicos entre os anos de 2010 e 2021, indexados nas bases de dados das plataformas de busca LILICAS, PubMed, Google Scholar e SciELO. Foram encontrados um total de 42 artigos científicos catalogados no período de 2010 até abril de 2021. Dos trabalhos obtidos, 17 encontram-se na PubMed, 4 na LILACS,11 SciELO e 10 no Google Scholar. Seguindo os critérios de exclusão, 30 resumos publicados antes do ano de 2010 foram excluídos. Foram também excluídos 6 dissertações, 2 teses e 2 capítulos de livro. Entre os 42 artigos analisados, 24 foram publicados em inglês, 18 em português e nenhum foi publicado em espanhol. Sendo assim, a partir desse estudo será possível adotar e atualizar as medidas preventivas contra a FMB, tais como: divulgação de informações, orientar os profissionais do sistema de saúde, , educação em saúde para população de risco, guiar as ações de vigilância em saúde e orientação de novas diretrizes das políticas públicas, relacionadas a um importante problema de saúde única, considerando-se os aspectos ambientais, de saúde humana e da presença dos animais, como as capivaras entre outros, e ainda dos vetores, como os carrapatos.
