Serological occurrence for tick-borne agents in beef cattle in the Brazilian Pa...
Ramos,Inalda Angélica de Souza; Mello,Victória Valente Califre de; Mendes,Natalia Serra; Zanatto,Diego Carlos de Souza; Campos,João Bosco VilelaAbstract This study investigated the seropositivity for five different tick-borne agents, namely Anaplasma marginale, Babesia bovis, Babesia bigemina, Coxiella burnetii, Anaplasma phagocytophilum, and Trypanosoma vivax in beef cattle in the Brazilian Pantanal. The serum samples collected from animals (200 cows; 200 calves) were used in indirect enzyme-linked immunosorbent assays (iELISA) to detect IgG antibodie...
Phylogeography of msp4 genotypes of Anaplasma marginale in beef cattle from the...
Ramos,Inalda Angélica de Souza; Herrera,Heitor Miraglia; Mendes,Natália Serra; Fernandes,Simone de Jesus; Campos,João Bosco VilelaAbstract The msp4 gene of A. marginale is unicodon, stable and mostly homogeneous, being considered as a useful marker for phylogeographic characterization of this bacterium. The objective of this work was to analyze the phylogeography of A. marginale based on the msp4 gene in beef cattle from the Brazilian Pantanal, compared to those found in other regions worldwide. The blood samples investigated were collect...
VALORES HEMATOLÓGICOS DE LOBINHOS (Cerdocyon thous) DO PANTANAL, MATO GROSSO DO...
Santos,Filipe Martins; Macedo,Gabriel Carvalho de; Barreto,Wanessa Teixeira Gomes; Nantes,Wesley Arruda Gimenes; Assis,William Oliveira deResumo O objetivo do trabalho foi avaliar a influência do sexo, da sazonalidade e de infecções por Trypanosoma cruzi e Trypanosoma evansi nos valores hematológicos de lobinhos (Cerdocyon thous) que habitam o Pantanal Sul-Mato-Grossense. Entre novembro de 2015 e outubro de 2016, foram amostrados 48 lobinhos. Os valores hematológicos mensurados foram as contagens de eritrócitos e leucócitos, volume globular e vol...
Pathological effects of acetone cyanohydrin in swiss rats
Rufino,Marcos Natal; Cereda,Marney Pascoli; Barreto,Wanessa Teixeira Gomes; Silva,Alanderson Rodrigues da; Andrade,Gisele Braziliano deABSTRACT Cassava has been widely used for animal and human nutrition. It has also been demonstrated to have antineoplastic and anthelmintic properties. Toxicity due to cassava consumption has been reported in ruminants and laboratory animals; therefore, this study aimed to investigate the toxic effects of acetone cyanohydrin, a metabolite of linamarin that is present in cassava, in Wistar rats. Six groups of fi...
Triatominae (Hemiptera, Reduviidae) in the Pantanal region: association with Tr...
Santos,Filipe Martins; Jansen,Ana Maria; Mourão,Guilherme de Miranda; Jurberg,José; Nunes,Alessandro Pacheco; Herrera,Heitor MiragliaABSTRACTINTRODUCTION: The transmission cycle of Trypanosoma cruzi in the Brazilian Pantanal region has been studied during the last decade. Although considerable knowledge is available regarding the mammalian hosts infected by T. cruzi in this wetland, no studies have investigated its vectors in this region. This study aimed to investigate the presence of sylvatic triatomine species in different habitats of the...
Caryospora bigenetica (Apicomplexa: Eimeriidae) in South America: new hosts and...
Viana,Lúcio André; Mecchi,Kamilla Costa; Nascimento,Leonardo França do; Herrera,Heitor Miraglia; Santa-Rita,Paula HelenaThe coccidian Caryospora bigenetica was first described in the snake Crotalus horridus (Viperidae) from United States of America. This study represents the first record of the occurrence of C. bigenetica in snakes in South America. Feces were sampled between November 2013 and May 2014 from 256 wild snakes maintained in scientific breeding facilities in the states of Mato Grosso do Sul (MS; n = 214) and Rio de J...
Molecular detection of hemotrophic mycoplasmas among domiciled and free-roaming...
Santis,Ana Cláudia Gabriela Alexandre de; Herrera,Heitor Miraglia; Sousa,Keyla Cartens Marques de; Gonçalves,Luiz RicardoHemoplasmas are bacteria living in feline red blood cells. Feline hemoplasmosis is frequently associated with old male cats that have access to the streets. This study aimed to detect the presence of hemoplasma speciess in domiciled and free-roaming cats in Campo Grande, state of Mato Grosso do Sul (MS), Brazil, using molecular techniques. Between January 2013 and April 2013, EDTA-whole blood samples were colle...
Serological detection of Toxoplasma gondii, Leishmania infantum and Neospora ca...
Sousa,Keyla Carstens Marques de; Herrera,Heitor Miraglia; Domingos,Iara Helena; Campos,João Bosco Vilela; Santos,Isabela Maria Campanelli dosAn investigation was made into the occurrence of antibodies to Toxoplasma gondii, Leishmania infantum and Neospora caninum in 151 domestic cats, based on the indirect fluorescent antibody test (IFAT). Serum samples were collected from 151 domestic cats (65 free-roaming and 86 domiciled cats; 55 males and 96 females) in Campo Grande, Mato Grosso do Sul, Brazil between January and April 2013. IgG antibodies to T....
Pathology of dogs in Campo Grande, MS, Brazil naturally co-infected with Leishm...
Andrade,Gisele Braziliano; Barreto,Wanessa Teixeira Gomes; Santos,Luciana Ladislau dos; Ribeiro,Laura Raquel Rios; Macedo,Gabriel Carvalho deDifferent parasites that commonly occur concomitantly can influence one another, sometimes with unpredictable effects. We evaluated pathological aspects of dogs naturally co-infected with Leishmania infantum and Ehrlichia canis. The health status of the dogs was investigated based on histopathological, hematological and biochemical analyses of 21 animals infected solely with L. infantum and 22 dogs co- infected...
Molecular and serological detection of tick-borne pathogens in dogs from an are...
Sousa,Keyla Carstens Marques de; André,Marcos Rogério; Herrera,Heitor Miraglia; Andrade,Gisele Braziliano de; Jusi,Marcia Mariza GomesTick-borne pathogens affect a wide range of vertebrate hosts. To identify tick-borne pathogens among dogs from Campo Grande, MS, Brazil testing seropositive for Leishmania infantum (syn. L. chagasi), a serological and molecular study was conducted to detect Ehrlichia canis, Anaplasma platys and Babesia vogeli in 60 serum and spleen samples. A confirmatory diagnosis of L. infantum based on serological and molecu...
