Braz,Beatriz Maria de Almeida; Silva,Raizza Barros Sousa; Lins,Suzanna Cavalcante; Silva,Diego Ricardo Xavier; Ramalho,Walter MassaAbstract INTRODUCTION: Visceral leishmaniasis has a broad worldwide distribution and constitutes a public health problem in the Northeast of Brazil. Located in this region is the state of Alagoas, where the disease is endemic in humans and where there has been a significant increase in the number of positive dogs. The objective of this study was to describe the temporal and spatial distribution of the cases of ...
Spatial analysis of canine leishmaniasis in an area of transmission of the semi...
Silva,Raizza Barros Sousa; Franco-Silva,Laysa Freire; Lima,Diana Azevedo; Freitas,Angélica Beatriz Araújo de Andrade; Ramalho,Walter MassaAbstract Visceral leishmaniasis is a widely distributed zoonosis and canine infection is an important indicator of risk for the occurrence of the disease in humans. The goal of this analysis was to study the spatial clustering of canine leishmaniasis (CL) in the municipality of Santa Luzia, state of Paraíba. For this, 749 samples of canine plasma were tested using three serological tests. The dog was considered...
Factors associated with Leishmania infection in dogs and geospatial analysis in...
Braz,Beatriz Maria de Almeida; Leite,Denny Parente de Sá Barreto Maia; Silva,Raizza Barros Sousa; Silva,Maria Luana Cristiny Rodrigues daAbstract Visceral leishmaniasis (VL) is a zoonosis with a worldwide distribution that has a major impact on public health. The aim of this study was to verify the prevalence of canine infection by Leishmania infantum, the factors associated with the infection and its spatial distribution in the municipality of Mãe D’Água, in the Sertão region of Paraíba State, Northeast Brazil. Blood samples were collected from...
High seroprevalence and associated factors for visceral leishmaniasis in dogs i...
Bernardino,Maria das Graças da Silva; Angelo,Débora Ferreira do Santos; Silva,Raizza Barros Sousa; Silva,Edijanio Galdino daAbstract Dogs have been implicated as main reservoirs for visceral leishmaniasis (VL) in urban areas. Therefore, studies on this species provide important data for public health. Thus, the objective of the present study was to ascertain the seroprevalence of canine VL (CVL) and the associated factors in the Brejo Paraibano microregion, northeastern Brazil. A total of 409 dogs were sampled from the eight municip...
Natural Infection by Leishmania infantum in domestic cats (Felis catus) in a mu...
Silva,Raizza Barros Sousa; Portela,Roseane de Araújo; Arruda,Luís Fernando Batista; Ferreira,Jefferson da Silva; Souto,Erick Platiní FerreiraAbstract The main clinical, anatomopathological, and molecular aspects of the infection by Leishmania infantum are described in two cats with multicentric cutaneous, nodular, and ulcerated lesions. The animals were submitted to a clinical examination, followed by serological, molecular and parasitological exams, with culture and isolation of the parasite, and subsequent isoenzymatic characterization. The animal...
Clinical aspects and diagnosis of leishmaniasis in equids: a systematic review ...
Limeira,Clécio Henrique; Alves,Clebert José; Azevedo,Sérgio Santos de; Santos,Carolina de Souza Américo Batista; Melo,Marcia Almeida deAbstract Leishmaniases are a group of diseases of zoonotic importance caused by over 20 species of protozoa of the genus Leishmania, in which domestic dogs are considered to be the main reservoir for the disease. However, the involvement of other vertebrates as reservoirs for these parasites has also been investigated. Therefore, the objective of the present study was to carry out a systematic review with meta-...
Demographic and clinical characterization of human visceral leishmaniasis in th...
Sousa,Jaqueline Maria Dos Santos; Ramalho,Walter Massa; Melo,Marcia Almeida deAbstract INTRODUCTION: Human visceral leishmaniasis (HVL) primarily occurs in regions that present socioeconomic, health, and environmental vulnerability. In Pernambuco, Brazil, this neglected zoonosis has expanded in magnitude as well as geographically, and efforts to manage HVL have been insufficient to contain its spread. The objective of this study was to describe the epidemiological profile of human illnes...
Ehrlichia canis and Rickettsia spp. in dogs from urban areas in Paraiba state, ...
Rotondano,Tereza Emmanuelle de Farias; Krawczak,Felipe da Silva; Barbosa,Werona de Oliveira; Moraes-Filho,Jonas; Bastos,Fernanda NieriAbstract The aims of our study was to identify Ehrlichia canis and antibodies against Rickettsia spp. belonging to the spotted fever group (SFG) in dogs sampled from Paraiba state, northeastern Brazil. Blood and serum samples collected by convenience from dogs in urban areas of five municipalities were analyzed by real-time PCR for the detection of E. canis DNA and by immunofluorescence assay test (IFAT) for th...
Canine visceral leishmaniasis in the Northeast Region of Brazil
Brito,Flávio Gonçalves; Langoni,Helio; Silva,Rodrigo Costa da; Rotondano,Tereza Emmanuelle de Farias; Melo,Marcia Almeida de; Paz,Giselle Souza daAbstract Background Visceral leishmaniasis (VL) is a zoonosis that affects dogs and other mammals, including humans. Contact with dogs is a major risk factor for humans. This disease is endemic in several regions of Brazil. The aim of this study was to determine the prevalence of Leishmania spp. infection in dogs and to correlate it with possible risk factors. Methods Blood samples were collected from 391 dogs ...
Survey of Ehrlichia canis, Babesia spp. and Hepatozoon spp. in dogs from a semi...
Rotondano,Tereza Emmanuelle de Farias; Almeida,Herta Karyanne Araújo; Krawczak,Felipe da Silva; Santana,Vanessa Lira; Vidal,Ivana FernandesThis study assessed the occurrence of Ehrlichia spp., Babesia spp. and Hepatozoon spp. infections in 100 tick-harboring dogs from a semiarid region of the State of Paraíba, Northeastern Brazil. Blood samples and ticks were collected from the animals, and a questionnaire was submitted to dog owners to obtain general data. Blood samples were used to perform hemogram, direct blood smear and immunological and molec...
