Assays to evaluate the transovarial transmission of Anaplasma marginale by Rhipicephalus microplus
(Elsevier, 2022-11)The aim of this study was to evaluate the vectorial competence of Rhipicephalus microplus to transmit Anaplasma marginale transovarially, by analyzing the results of three different but complementary assays. First, larvae ... -
Casos de anaplasmosis, babesiosis y tripanosomiasis bovina registradas en el INTA Rafaela (2012-2019)
(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste, 2022-06)Anaplasmosis, babesiosis y tripanosomiasis de los bovinos son enfermedades de importancia económica provocadas por Anaplasma marginale, Babesia bovis y/o Babesia bigemina, y Trypanosoma vivax, respectivamente. En este ... -
Development and field evaluation of a nested polymerase chain reaction-restriction fragment length polymorphism (nPCR-RFLP) analysis to identify A. marginale-infected and A. centrale-vaccinated cattle
(Elsevier, 2022-07)A nested polymerase chain reaction-restriction fragment length polymorphism (nPCR-RFLP) assay based on the amplification of the Anaplasma spp. highly conserved msp5 gene and posterior digestion with HindIII endonuclease ... -
Development and field evaluation of an ELISA to differentiate Anaplasma marginale–infected from A. centrale–vaccinated cattle
(American Association of Veterinary Laboratory Diagnosticians, 2023-03)Immunization of calves with Anaplasma centrale is used to prevent acute anaplasmosis caused by A. marginale. Natural and vaccine-acquired immunity is detected through serologic tests based primarily on A. marginale recombinant ... -
Does parity order or cow antibody level influence the humoral immunity of calves for cattle anaplasmosis?
(Springer, 2024-02)Anaplasmosis is a widely distributed vector-borne disease of cattle caused by the bacteria Anaplasma marginale, which may lead to severe losses in beef and dairy cattle production. Anecdotal information among farmers ... -
Migration of Rhipicephalus microplus ticks among cattle
(Royal Entomology Society, 2022-11)The aim of this work was to quantitatively analyse the magnitude of the migration of Rhipicephalus microplus ticks among cattle under field conditions, in groups of bovines with different stocking rates. The role of this ... -
Sensitivity of Anaplasma marginale genotypes to oxytetracycline assessed by analyzing the msp1α gene in experimentally infected cattle
(Elsevier, 2021-09)The aim of this study was to evaluate the influence of the long-acting oxytetracycline (OTC) treatment on A. marginale genotypes of the isolate S1P, by analyzing the msp1α genotype based on a microsatellite (ms) and tandem ...
