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...
Genetic diversity of Babesia bovis studied longitudinally under natural transmi...
Matos,Carlos António; Silva,Jenevaldo Barbosa da; Gonçalves,Luiz Ricardo; Mendes,Natalia Serra; Alvarez,Dasiel Obregón; André,Marcos RogérioAbstract Serum and DNA samples from 15 naturally infected calves in Seropédica, Brazil, were obtained quarterly from birth to 12 months of age, in order to longitudinally evaluate their humoral immune response against Babesia bovis and the merozoite surface antigen diversity of B. bovis. Anti-B. bovis IgG antibodies were detected by an indirect fluorescent antibody test (IFAT) and enzyme-linked immunosorbent as...
Molecular detection of vector-borne agents in cats in Southern Brazil
Pedrassani,Daniela; Biolchi,Juliano; Gonçalves,Luiz Ricardo; Mendes,Natalia Serra; Zanatto,Diego Carlos de Souza; Calchi,Ana CláudiaAbstract This study used serological and molecular methods to investigate the occurrence of vector-borne pathogens (VBP) with zoonotic potential in cats neutered at the University Veterinary Hospital in Canoinhas, Santa Catarina. The combined PCR and serological results revealed that 17 (56.6%) cats were positive for one or more pathogens. The sampled cats had antibodies to Ehrlichia spp. (7/30), Anaplasma phag...
Longitudinal evaluation of humoral immune response and merozoite surface antige...
Matos,Carlos António; Gonçalves,Luiz Ricardo; Alvarez,Dasiel Obregón; Freschi,Carla Roberta; Silva,Jenevaldo Barbosa da; Val-Moraes,Silvana PompeiaAbstract Babesiosis is an economically important infectious disease affecting cattle worldwide. In order to longitudinally evaluate the humoral immune response against Babesia bovis and the merozoite surface antigen diversity of B. bovis among naturally infected calves in Taiaçu, Brazil, serum and DNA samples from 15 calves were obtained quarterly, from their birth to 12 months of age. Anti-B. bovis IgG antibod...
