Item Revisiting Brazilian spotted fever focus of Caratinga, Minas Gerais state, Brazil.(2006) Galvão, Márcio Antônio Moreira; Cardoso, Luciane Daniele; Mafra, Cláudio Lísias; Calic, Simone Berger; Walker, David HughesWe revisited a Brazilian spotted fever focal area in Minas Gerais state, Brazil, in 2002, and performed a serologic survey in dogs and cats. The results of this survey are compared with the survey made 10 years before. The possible efficacy of vector control measures adopted in this area and the role of dogs and horses as sentinels of infection by Rickettsia are discussed.Item Old and new human rickettsiosis in Minas Gerais state, Brazil.(2005) Calic, Simone Berger; Rocha, Christiane Maria Barcellos Magalhães da; Leite, Romário Cerqueira; Mafra, Cláudio Lísias; Galvão, Márcio Antônio MoreiraThe authors describe cases of Brazilian spotted fever (BSF) diagnosed in Minas Gerais state, Brazil, by the Minas Gerais Public Health Laboratory, Ezequiel Dias Foundation from 1995 to 2004. In addition they present three cases of human Rickettsia felis rickettsiosis from Minas Gerais diagnosed in France in 1999, and the first two suspected cases of human monocytic ehrlichiosis (HME) diagnosed in Ezequiel Dias Foundation in 2001. In both cases a differential diagnose was made with BSF.Item Human ehrlichioses in Brazil : first suspect cases.(2004) Calic, Simone Berger; Galvão, Márcio Antônio Moreira; Bacellar, Fátima; Rocha, Christiane Maria Barcellos Magalhães da; Mafra, Cláudio Lísias; Leite, Romário Cerqueira; Walker, David HughesBrazilian 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 Granulocytic Anaplasmosis (HGA) and Human Monocytic Ehrlichiosis (HME), have been described in many countries. These diseases can present symptoms similar to rickettsioses of the spotted fever group, and they are transmitted by ixodid ticks. The first two suspected cases of human ehrlichiosis in Brazil were first considered to be cases of BSF. The differential diagnosis was made at the Minas Gerais Rickettsiosis Public Health Laboratory. The clinical and laboratory findings, with positive serology for the HME agent, indicated suspected cases of human ehrlichioses in Brazil.Item Spotted fever rickettsiosis in Coronel Fabriciano, Minas Gerais State.(2003) Galvão, Márcio Antônio Moreira; Calic, Simone Berger; Chamone, Chequer Buffe; Siqueira, Cláudio Lísias Mafra de; Cesarino Filho, Gracco; Olano, Juan Pablo; Walker, David HughesWe report cases of spotted fever rickettsiosis in Coronel Fabriciano Municipality of Minas Gerais State, Brazil. The cases occurred in May and June of 2000. During this period there were two deaths among children from an area named Pedreira in a periurban area of this municipality. In a boy who died with clinical manifestations of Brazilian spotted fever, a necropsy revealed the presence of a spotted fever group Rickettsia. The serological results confirm the difficulty in the differential diagnosis of patients with symptoms of rickettsial diseases.Item Molecular identification of Rickettsia felis in ticks and fleas from an endemic area for Brazilian Spotted Fever.(2008) Oliveira, Karla Andrade de; Oliveira, Luciana Souza de; Dias, Camila Cristina Almeida; Silva Júnior, Abelardo; Lamëgo, Márcia Rogéria de Almeida; Almada, G.; Bouyer, Donald H.; Galvão, Márcio Antônio Moreira; Siqueira, Cláudio Lísias Mafra deRickettsioses 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 Amblyomma cajennense, Amblyomma dubitatum (A. cooperi), Riphicephalus sanguineus, Anocentor nitens and Ctenocephalides felis, was collected from domestic animals and the environment and separated in 152 lots according to the origin. Rickettsia sp. was detected in pools of all collected species by amplification of 17kDa pro¬tein-encoding gene fragments. The products of PCR amplification of three samples were sequenced, and Rickettsia felis was identified in R. sanguineus and C. felis. These results confirm the presence of Rickettsia felis in areas previ¬ously known as endemic for BSF, disease caused by Rickettsia rickettsii. Moreover, they show the needing of further studies for deeper knowledge of R. felis-spotted fever epidemiology and differentiation of these diseases in Brazil.
