25. Molecular identification of Rickettsia felis in ticks and fleas from an endemic area for Brazilian Spotted Fever
Rickettsioses are arthropod-borne diseases caused by parasites from the Order Rickettsiales. The most prevalent rickettsial disease in Brazil is Brazilian Spotted Fever (BSF). This work intends the molecular detection of those agents in ectoparasites from an endemic area of BSF in the state of Espírito Santo. A total of 502 ectoparasites, among them Amblyom

26. Brazilian spotted fever: a reemergent zoonosis
Brazilian spotted fever is caused by the bacterium Rickettsia rickettsii, which is the most pathogenic species of the spotted-fever rickettsiae group and is transmitted by the bite of infected ticks. Amblyomma cajennense is the most important tick species involved in the cycle of this zoonosis in Brazil as it presents low host specificity, great number of na

27. Estudos biológicos de Rhipicephalus sanguineus e interação Rickettsia rickettsii, R. sanguineus e cães em condições laboratoriais. / Biological studies on Rhipicephalus sanguineus and interactions of Rickettsia rickettsii, R. sanguineus and dogs under laboratory conditions.
The bacterium Rickettsia rickettsii is the etiological agent of an acute, severe human disease called Rocky Mountain Spotted Fever in the United States or Brazilian Spotted Fever in Brazil. The infection occurs through the tick bite. Reports of clinical illness on dogs due to this agent have been restricted to the United States. The brown dog tick or kennel

28. Aspectos ecológicos da febre maculosa brasileira em um foco endêmico no Estado de São Paulo / Ecological aspects of Brazilian Spotted Fever in an endemic area in the State of São Paulo
Foi conduzido um estudo sobre a ecologia da Febre Maculosa Brasileira, causada pela bactéria Rickettsia rickettsii, em uma área endêmica, no distrito de Taiaçupeba, Município de Mogi das Cruzes, SP. Para o melhor entendimento de quais animais silvestres são os hospedeiros das formas imaturas do carrapato vetor, Amblyomma aureolatum, foram capturados en

29. Freqüência de anticorpos Anti-Rickettsia spp em cães da cidade de Belo Horizonte, Minas Gerais, Brasil, 2005.
Brazilian Spotted Fever (BSF), caused by Rickettsia rickettsii, is endemic and highly lethal for humans in some areas of Southeastern Brazil. However, in the city of Belo Horizonte, capital of the state of Minas Gerais, BSF is not endemic. The present study aimed to evaluate rickettsial infection among the canine population of Belo Horizonte. For this purpos

30. Survey of Rickettsia spp. in Amblyomma dubitatum Neumann 1899 and Amblyomma triste Koch 1844 ticks from Brazil and Uruguay, respectivily / Pesquisa de Rickettsia spp. em carrapatos Amblyomma dubitatum Neumann 1899 e Amblyomma triste Koch 1844, provenientes do Brasil e Uruguai, respectivamente
Owing to the potential role of the tick Amblyomma dubitatum and Amblyomma triste in the transmission of the Spotted Fever Group (SFG) Rickettsia, this study evaluated infection by Rickettsia in ticks collected in Brazil and Uruguay, where rickettsial infection is endemic. A total of 841 (367 males e 474 females) A. dubitatum adult ticks were collected in Ped

31. Detection of Rickettsia rickettsii in the tick Amblyomma cajennense in a new Brazilian spotted fever-endemic area in the state of Minas Gerais
The present study evaluated rickettsial infection in Amblyomma spp. ticks collected in a farm in Coronel Pacheco, a Brazilian spotted fever (BSF) endemic area. A total of 78 A. cajennense and 78 A. dubitatum free-living adult ticks were collected and tested by polymerase chain reaction (PCR) targeting a fragment of the rickettsial gene gltA. Only one pool of

32. Antibodies to Rickettsia rickettsii, Rickettsia typhi, Coxiella burnetii, Bartonella henselae, Bartonella quintana, and Ehrlichia chaffeensis among healthy population in Minas Gerais, Brazil
Rickettsial diseases except those belonging to spotted fever group rickettsioses are poorly studied in South America particularly in Brazil where few epidemiological reports have been published. We describe a serosurvey for Rickettsia rickettsii, R. typhi, Coxiella burnetii, Bartonella henselae, B. quintana, and Ehrlichia chaffeensis in 437 healthy people fr

33. Detection of Brazilian spotted fever infection by polymerase chain reaction in a patient from the state of São Paulo
Brazilian spotted fever (BSF) cases have been increasing in the state of São Paulo but no genomic information about local rickettsia isolated from humans has been well documented. We recovered spotted-fever group rickettsiae from a sample of patient blood cultured in Vero cells using the shell vial technique. Rickettsial DNA fragments (gltA, ompA, and, ompB

34. Human ehrlichioses in Brazil: first suspect cases
Brazilian spotted fever (BSF) rickettsiosis is the most common and recognized of the human rickettsioses in Brazil. It is difficult to establish the diagnosis of human rickettsiosis infection by routine microbiologic methods, creating a false idea that Rickettsia and Ehrlichia infections are rare and without importance. New tick-borne diseases, like Human Gr

35. DETECÇÃO E CARACTERIZAÇÃO DE Rickettsia spp. CIRCULANTE EM FOCO INATIVO PERI-URBANO DO MUNICÍPIO DE CARATINGA, MG
As riquétsias patogênicas constituem um grupo de bactérias gram-negativas, intracelulares obrigatórias responsáveis por várias doenças humanas conhecidas como riquetsioses, as quais são transmitidas ao homem através da picada de artrópodes hematófagos como carrapato, pulga e piolho. O Brasil apresenta histórico de doença riquetsial desde o final

36. Isolamento e detecção molecular de riquétsias do Grupo Febre Maculosa, a partir de Amblyomma cajennense (Fabricius, 1787) e espécimens biológicos humanos, provenientes de áreas endêmicas do Estado de São Paulo / SPOTTED FEVER GROUP RICKETTSIAE ISOLATION AND MOLECULAR DETECTION, FROM Amblyomma cajennense (FABRICIUS, 1787) AND HUMAN, FROM ENDEMIC AREAS OF STATE OF SÃO PAULO.
Brazilian spotted fever (BSF), a disease caused by spotted fever group rickettsiae (SFGR) transmitted by Amblyomma cajennense, is generally fatal when not early treated. Common laboratory methods (Vero cell culture and immunofluorescence indirect assay) are not efficient on the diagnosis in most of the cases observed in State of São Paulo, where the agent i
