Introducción: La babesiosis bovina es causada por parásitos Apicomplexa del género Babesia, siendo la Babesia bovis la especie asociada con cuadros clínicos más graves de la enfermedad. La invasión de B. bovis a los eritro-citos bovinos implica la interacción entre moléculas de los merozoítos de...
Abstract 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 I...
Introducción. Babesia bovis es el principal agente causal de la babesiosis bovina, una importante enfermedad
veterinaria transmitida por garrapatas a nivel mundial. Las estrategias convencionales para controlar esta parasitosis han presentado múltiples limitaciones por lo que el desarrollo de una vacun...
Abstract This study aimed to determine the dynamics of natural infection in the transmission of Babesia spp. to cattle in an enzootic instability area in Northeastern Brazil. Blood samples were collected from 30 calves located on two dairy farms to determine the packed cell volume (PCV) and the timing of...
Abstract 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 s...
A case of prenatal Babesia bovis infection in Brazil in a 17 year-old Holstein X Brown Swiss cow which aborted at approximately eight months of gestation is described and discussed. The newborn calf outlived for few minutes and then died. At necropsy, the thoracic and abdominal cavities were filled by a ...
O presente trabalho objetivou o estudo de parte do ciclo da Babesia bovis no seu hospedeiro invertebrado, o carrapato Boophilus microplus. Analisou-se a capacidade de infecçäo e transmissäo transovariana de B. bovis em partenóginas de B. microplus, alimentadas em bovinos portadores e enfermos por est...
Sera collected from 417 dairy cows from Londrina, PR, Brazil, were analysed by the indirect fluorescent antibody test (IFAT) for the presence of anitbody against Babesia bigemina, Babesia bovis e Anaplasma marginale. All samples were tested diluted 1:80 using rabbit anti-bovine IgG FITC conjugate diluted...
Uma preparaçäo antigênica bruta de Babesia bovis, preparada a partir de cultivo celular, foi liofilizada e utilizada em um teste de ELISA para detecçäo de anticorpos. O valor discriminante foi calculado pela média de amostras de soros negativos acrescida de dois desvios padröes. As duas séries de...
El estudio fue realizado para determinar la presencia de la babesia equina en el departamento de Santa Cruz, provincias Andres Ibañez, Warnes y Ñuflo de Chavez, Se muestrearon al azar 260 equinos tomando en cuenta la zona, la edad, raza y sexo en los cuales se observaron al microscopio frotis sanguineo...
