Glycoproteins located on the luminal surface of the plasma membrane of tick gut epithelial cells, when used to vaccinate cattle, are capable of stimulating an immune response that protects cattle against subsequent tick infestation. One such tick gut glycoprotein, designated Bm86, has been purified to homogeneity and the amino acid sequences of peptide fragments generated by endoproteinase Lys-...

El estudio de estabilidad proteínas es un proceso indispensable en la actualidad para el desarrollo productos vacunales que contienen a éstas como principio activo. presente trabajo se realizó Centro Ingeniería Genética y Biotecnología Camagüey, cual actualmente área Desarrollo Tecnológico trabaja diseño una vacuna contra las garrapatas. objetivo este consistió determinar tiempo inactivación pr...

The cattle industry is one of the most important agroeconomic activities in Mexico. The national herd is estimated to include approximately 33.5. million head of cattle. Ticks and tick-borne diseases are principal factors with a negative impact on cattle health and production. The most economically important tick species parasitizing cattle in Mexico are Rhipicephalus microplus, R. annulatus, a...

The cattle tick, Rhipicephalus microplus, is arguably the world's most economically important external parasite of cattle. Sustainable cattle tick control strategies are required to maximise the productivity of cattle in both large production operations and small family farms. Commercially available synthetic acaricides are commonly used in control and eradication programs, but indiscriminate p...

BACKGROUND The Gavac vaccine against the cattle tick Boophilus microplus has proven its efficacy in a large number of controlled and field experiments. However, this vaccine could be further improved by searching for new alternative adjuvants that would induce a stronger long-lasting immune response. We conducted several experiments to assay the adjuvant effect of fractions of the recombinant y...
