Biological parameters of Amblyomma coelebs Neumann, 1906 (Acari: Ixodidae) unde...
Aguirre,André de Abreu Rangel; Rodrigues,Vinicius da Silva; Costa,Ivaneide Nunes da; Garcia,Marcos Valerio; Higa,Leandro de Oliveira SouzaAbstract One generation of Amblyomma coelebs life cycle under experimental conditions was evaluated. Ten tick pairs were allowed to feed on rabbits under laboratory conditions (LC), resulting six engorged females with a mean weight of 1,403.9 mg. Two females were maintained in a forest reserve under natural conditions (NC), and four were maintained in incubators (LC). The engorgement period lasted 10.33 days. P...
Antigenic characterization of Trypanosoma evansi using sera from experimentally...
Aquino,Lúcia Padilha Cury Thomaz; Machado,Rosangela Zacarias; Lemos,Karen Regina; Marques,Luiz Carlos; Garcia,Marcos Valerio; Borges,Gustavo PuiaThe present research investigated the presence of T. evansi antibodies in animals from the subregion of Nhecolandia, in the Pantanal Sul-mato-grossense, by means of an enzyme linked immunosorbent assay (ELISA) and indirect immunofluorescence antibody test (IFAT), and the pattern of polypeptide recognition by sera from experimentally and naturally infected hosts using Western blotting. Serum samples were obtaine...
Mechanism of infection and colonization of Rhipicephalus sanguineus eggs by Mer...
Garcia,Marcos Valerio; Monteiro,Antonio Carlos; Szabo,Matias Juan Pablo; Prette,Nancy; Bechara,Gervásio HenriqueThe present work aimed to verify the penetration pattern of the Metarhizium anisopliae fungus into Rhipicephalus sanguineus tick eggs, as well as the lesions occurred inside the egg. The fungus adherence and penetration were studied by scanning electron microscopy and the action of fungus in the internal tissues was evaluated through conventional histological sessions. For the observation of these events, exper...
Colonização e lesão em fêmeas ingurgitadas do carrapato Rhipicephalus sanguineu...
Garcia,Marcos Valerio; Monteiro,Antonio Carlos; Szabó,Matias Pablo JuanO presente trabalho teve como objetivo verificar a forma de penetração do fungo Metarhizium anisopliae [METSCH. (SOROKIN, 1883)] em carrapatos da espécie Rhipicephalus sanguineus (LATREILLE, 1806), assim como as lesões infringidas nos tecidos internos do ácaro. A forma de aderência e penetração do fungo foi estudada através da microscopia eletrônica de varredura e a ação do fungo nos tecidos internos avaliada e...
