(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2016)Se realizó un muestreo de 62 pulmones bovinos en una carnicería y un frigorífico de la zona oeste del conurbano bonaerense. De uno de ellos, adquirido en una carnicería, y sin lesiones visibles compatibles con tuberculosis, ... -
An integrative analysis of post-translational histone modifications in the marine diatom Phaeodactylum tricornutum
(BioMed Central, 2015)Background: Nucleosomes are the building blocks of chromatin where gene regulation takes place. Chromatin landscapes have been profiled for several species, providing insights into the fundamental mechanisms of ... -
Main and epistatic QTL analyses for Sclerotinia Head Rot resistance in sunflower
(PLOS, 2017-12)Sclerotinia Head Rot (SHR), a disease caused by Sclerotinia sclerotiorum, is one of the most limiting factors in sunflower production. In this study, we identified genomic loci associated with resistance to SHR to support ... -
Characterization of the two component regulatory system PhoPR in Mycobacterium bovis
(Elsevier, 2018-08)Mycobacterium bovis is the causative agent of bovine tuberculosis and is a member of Mycobacterium tuberculosis complex, which causes tuberculosis in a number of mammals including humans. Previous studies have shown that ... -
Tuberculosis vaccine candidates based on mycobacterial cell envelope components
(Elsevier, 2019-03)Even after decades searching for a new and more effective vaccine against tuberculosis, the scientific community is still pursuing this goal due to the complexity of its causative agent, Mycobacterium tuberculosis (Mtb). ... -
The autographa californica multiple nucleopolyhedrovirus Ac12: A non-essential F box-like protein that interacts with cellular SKP1 component of the E3 ubiquitin ligase complex
(Elsevier, 2019-01)The Autographa californica multiple nucleopolyhedrovirus (AcMNPV) ac12 gene, which is conserved in ten other baculovirus, codes a predicted 217 amino acid protein of unknown function. In this study, we investigated the ... -
Immune receptor genes and pericentromeric transposons as targets of common epigenetic regulatory elements
(Wiley, 2018-12)Pattern recognition receptors (PRR) and nucleotide‐binding leucine‐rich repeat proteins (NLR) are major components of the plant immune system responsible for pathogen detection. To date, the transcriptional regulation of ... -
Novel Effector Protein EspY3 of Type III Secretion System from Enterohemorrhagic Escherichia coli Is Localized in Actin Pedestals
(MDPI AG, 2018)Enterohemorrhagic Escherichia coli (EHEC) and enteropathogenic Escherichia coli (EPEC) are attaching and effacing (A/E) pathogens, which translocate effector proteins to intestinal enterocytes through a type III secretion ... -
ASR1 transcription factor and its role in metabolism
(Taylor & Francis, 2015-03)Asr1 (ABA, stress, ripening) is a plant gene widely distributed in many species which was discovered by differential induction levels in tomato plants subjected to drought stress conditions. ASR1 also regulates the expression ... -
Baculovirus capsid display in vaccination schemes: effect of a previous immunity against the vector on the cytotoxic response to delivered antigens
(Springer, 2018-12)The baculovirus Autographa californica multiple nuclear polyhedrosis virus (AcMNPV) infects lepidopteran invertebrates as natural hosts, although it also has been used as display vector for vaccine development. In this ... -
Mapping causal mutations by exome sequencing in a wheat TILLING population: a tall mutant case study
(Springer, 2018-04)Forward genetic screens of induced mutant plant populations are powerful tools to identify genes underlying phenotypes of interest. Using traditional techniques, mapping causative mutations from forward screens is a lengthy, ... -
Identification of bovine tuberculosis biomarkers to detect tuberculin skin test and IFNγ release assay false negative cattle
(Elsevier, 2019-02)Bovine tuberculosis (bTB) is an important animal and zoonotic disease, which causes severe economic losses. The main focus of this study was to assess the predictive power of previously identified biomarkers of bTB in ... -
Recombinant occlusion bodies of baculovirus as carriers of a nonstructural protein of foot-and-mouth disease virus
(Springer, 2018-11)Here, we developed a diagnostic ELISA for foot-and-mouth disease using recombinant occlusion bodies (rOBs) of baculovirus. We fused Δ3AB1–3, a polypeptide derived from non-structural proteins of foot-and-mouth disease ... -
Diversidad de especies de micobacterias no tuberculosas aisladas en ambientes acuáticos de la ciudad de General Pico, La Pampa, Argentina = Species diversity of non-tuberculous mycobacteria isolated from aquatic environments of General Pico city, Province of La Pampa (Argentina)
(Asociación Argentina de Microbiología, 2018)Las micobacterias no tuberculosas (MNT) no solo se estudian por su importancia como patógenos oportunistas, sino también por sus aplicaciones en biotecnología y biorremediación. Nuestro objetivo fue determinar la presencia ... -
