Variation in the VP1 Gene of Foot-And-Mouth Disease Virus Serotype a Associated with Epidemiological Characteristics of Outbreaks in the 2001 Epizootic in Argentina
(Sage Publishing, 2008)A mixed binomial Bayesian regression model was used to quantify the relation between nucleotide differences in the VP1 gene of Foot-and-mouth disease virus (FMDV) serotype A, and epidemiologic characteristics of the outbreaks ... -
Overexpression of snakin-1 gene enhances resistance to Rhizoctonia solani and Erwinia carotovora in transgenic potato plants
(Wiley-Blackwell, 2008-05)Snakin‐1 (SN1), a cysteine‐rich peptide with broad‐spectrum antimicrobial activity in vitro, was evaluated for its ability to confer resistance to pathogens in transgenic potatoes. Genetic variants of this gene were cloned ... -
A candidate gene survey of quantitative trait loci affecting chemical composition in tomato fruit
(Society for Experimental Biology, 2008-07)In tomato, numerous wild-related species have been demonstrated to be untapped sources of valuable genetic variability, including pathogen-resistance genes, nutritional, and industrial quality traits. From a collection of ... -
Mal de Río Cuarto virus (MRCV) genomic segment S3 codes for the major core capsid protein
(Springer, 2009-06)Mal de Río Cuarto virus (MRCV) is a newly described species of the genus Fijivirus, family Reoviridae. Compared with other plant-infecting genus of the family, the function and localization of MRCV and other Fijivirus ... -
Virus infection elevates transcriptional activity of miR164a promoter in plants
(BioMed Central, 2009-12)Background: Micro RNAs (miRs) constitute a large group of endogenous small RNAs that have crucial roles in many important plant functions. Virus infection and transgenic expression of viral proteins alter accumulation and ... -
Developments in plant-based vaccines against diseases of concern in developing countries
(BENTHAM Open, 2010)Vaccination has been extensively used to prevent, eradicate and control infectious diseases. However, the development and implementation of new vaccines remains prohibitively expensive for middle and low income countries where ... -
Differences in the virulence of two strains of Foot-and-Mouth Disease Virus Serotype A with the same spatiotemporal distribution
(Elsevier, 2010-01)During the 2000–2001 epidemic of Foot-and-Mouth Disease Virus (FMDV) in Argentina, two FMDV serotype A viruses were identified among others. Since different pathogenic properties between these virus strains were noticed ... -
Trans-complementation of polyhedrin by a stably transformed Sf9 insect cell line allows occ− baculovirus occlusion and larval per os infectivity
(Elsevier, 2010-01-15)Oral infection of insect larvae with baculovirus is an advantageous methodology for producing high levels of recombinant proteins and for achieving plague control. However, many recombinant baculoviruses express a foreign ... -
Preparation of a working seed lot of BCG and quality control by PCR genotyping
(Asociación Argentina de Microbiología, 2010-04)The bacillus Calmette-Guérin (BCG) was obtained in 1920 after successive passages leading to the attenuation of a Mycobacterium bovis strain. For the following 40 years, BCG had been replicated, resulting in substrains ... -
