(Elsevier, 2013-02)Spoligotyping is the most frequently used method for genotyping isolates of Mycobacterium bovis worldwide. In the current work, we compared spoligotypes from 1684 M. bovis isolates from Argentina (816), Brazil (412), Chile ... -
Bases moleculares de la interacción virus-planta : relación entre genes de defensa, ARNs pequeños y sintomatología
(Facultad de Agronomía, Universidad de Buenos Aires, 2013-03)Los virus fitopatógenos producen alteraciones en el metabolismo y la fisiología de sus huéspedes provocadas principalmente por alteraciones en la expresión génica durante las infecciones. Numerosos cambios están asociados ... -
Galacturonosyltransferase 4 silencing alters pectin composition and carbon partitioning in tomato
(2013-04)Pectin is a main component of the plant cell wall and is the most complex family of polysaccharides in nature. Its composition is essential for the normal growth and morphology pattern, as demonstrated by pectin-defective ... -
Mycobacterium bovis Dmce2 double deletion mutant protects cattle against challenge with virulent M. bovis
(Elsevier, 2013-05)A Mycobacterium bovis strain deleted in mce2A and mce2B genes (M. bovis Δmce2) was tested as an experimental vaccine in cattle challenged with a virulent M. bovis strain. Three-and-a-half-month old calves (n = 5 to 6 per ... -
Transient expression of VP2 in Nicotiana benthamiana and its use as a plant-based vaccine against Infectious Bursal Disease Virus
(Elsevier, 2013-05-28)Infectious Bursal Disease Virus (IBDV) is the etiological agent of an immunosuppressive and highly contagious disease that affects young birds. This disease causes important economic losses in the poultry industry worldwide. ... -
VP1 protein of Foot-and-mouth disease virus (FMDV) impairs baculovirus surface display
(Elsevier, 2013-07)The Foot-and-mouth disease virus (FMDV) causes important economical losses in livestock farming. In order to develop a novel subunit vaccine against FMDV, we constructed recombinant baculoviruses that display the protein ... -
Agroinoculation of a full-length cDNA clone of cotton leafroll dwarf virus (CLRDV) results in systemic infection in cotton and the model plant Nicotiana benthamiana
(2013-07)Cotton blue disease is the most important viral disease of cotton in the southern part of South America. Its etiological agent, cotton leafroll dwarf virus (CLRDV), is specifically transmitted to host plants by the aphid ... -
