(Wolters Kluwer, 2019-09)Background: Argentina is considered a country with a middle tuberculosis (TB) incidence. However, according to the last national epidemiological report released in 2018, since 2013, the trends are steadily increasing. The ... -
Type VI secretion system in pathogenic escherichia coli: structure, role in virulence, and acquisition
(Frontiers Media, 2019-08)Bacterial pathogens utilize a myriad of mechanisms to invade mammalian hosts, damage tissue sites, and evade the immune system. One essential strategy of Gram-negative bacteria is the secretion of virulence factors through ... -
ViralPlaque: a Fiji macro for automated assessment of viral plaque statistics
(PeerJ, 2019-09)laque assay has been used for a long time to determine infectious titers and characterize prokaryotic and eukaryotic viruses forming plaques. Indeed, plaque morphology and dimensions can provide information regarding the ... -
P0 protein of cotton leafroll dwarf virus-atypical isolate is a weak RNA silencing suppressor and the avirulence determinant that breaks the cotton Cbd gene-based resistance
(Wiley, 2019-08)Cotton blue disease (CBD) is the most important disease present in cotton crops in South America and cotton leafroll dwarf virus (CLRDV) is the causal agent. The disease has been controlled by sowing cotton varieties ... -
Plant-based vaccine candidate against Infectious bursal disease: an alternative to inactivated vaccines for breeder hens
(Elsevier, 2019-08)Infectious bursal disease (IBD) is an acute, highly contagious immunosuppressive disease that affects young birds causing important economic losses in the poultry industry worldwide. Strict hygiene management together with ... -
Systemic administration of imiquimod as an adjuvant improves immunogenicity of a tumor-lysate vaccine inducing the rejection of a highly aggressive T-cell lymphoma
(Elsevier, 2019-06)T-cell lymphomas include diverse malignancies. They are rare, some have low survival rates and they lack curative therapies. The aim of this work was to assess whether employing the TLR7 agonist imiquimod and the T-cell ... -
Bovine macrophages responses to the infection with virulent and attenuated Leptospira interrogans serovar Pomona
(Elsevier, 2019-06)Leptospirosis is a zoonosis, caused by pathogenic spirochetes of the genus Leptospira. Although cattle are usually the maintenance hosts of serovar Hardjo, Pomona is the most frequent serovar circulating in Argentina. The ... -
Prevalence and species diversity of nontuberculous mycobacteria in drinking water supply system of Bahía Blanca City, Argentina
(Wolters Kluwer; Asian African Society of Mycobacteriology, 2019-06)Background: There is evidence that tap water is the vehicle through which nontuberculous mycobacteria (NTM) infect or colonize the human body. The objective of this study was to determine the presence and diversity of NTM ... -
Snakin/GASA proteins : involvement in hormone crosstalk and redox homeostasis
(Taylor & Francis, 2012)Snakin/GASA proteins are widely distributed among plant species. They are expressed in different plant organs with high tissue and temporal specificity, and their subcellular localization varies among the different members. ... -
Potato Snakin-1 Gene Silencing Affects Cell Division, Primary Metabolism, and Cell Wall Composition
(American Society of Plant Biologists, 2012-01)Snakin-1 (SN1) is an antimicrobial cysteine-rich peptide isolated from potato (Solanum tuberosum) that was classified as a member of the Snakin/Gibberellic Acid Stimulated in Arabidopsis protein family. In this work, a ... -
Klebsiella pneumoniae ST258 negatively regulates the oxidative burst in human neutrophils
(Frontiers Media, 2019-04)The epidemic clone of Klebsiella pneumoniae (Kpn), sequence type 258 (ST258), carbapenamase producer (KPC), commonly infects hospitalized patients that are left with scarce therapeutic option since carbapenems are last ... -
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 ... -
In vivo subcellular localization of Mal de Río Cuarto virus (MRCV) non-structural proteins in insect cells reveals their putative functions
(Elsevier, 2012-09)The in vivo subcellular localization of Mal de Río Cuarto virus (MRCV, Fijivirus, Reoviridae) non-structural proteins fused to GFP was analyzed by confocal microscopy. P5-1 showed a cytoplasmic vesicular-like distribution ... -
A computational study of the interaction of the foot and mouth disease virus VP1 with monoclonal antibodies
(Elsevier, 2015-10)Foot and mouth disease is caused by a non-enveloped virus (FMDV), which disposes several antigenic sites at the surface of their capsid proteins. The most relevant and immunodominant antigenic site of FMDV (site A or AnSA) ... -
Optimization of cellobiohydrolase production and secretome analysis of Trametes villosa LBM 033 suitable for lignocellulosic bioconversion
(Taylor & Francis, 2019-04)The production of bioethanol from lignocellulosic biomass comprises the enzymatic hydrolysis of lignocellulosic structures by three major cellulases. Among them, cellobiohydrolases are considered to be key enzymes playing ... -
Identification of four novel DC-SIGN ligands on Mycobacterium bovis BCG
(Springer, 2010-09)Dendritic-cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN; CD209) has an important role in mediating adherence of Mycobacteria species, including M. tuberculosis and M. bovis BCG to human ... -
Surface Display of AcMNPV Occlusion-Derived P74 Does Not Enhance Oral Infectivity of Budded Viruses
(S. Karger AG, 2012-02)Baculovirus occlusion-derived viruses (ODVs) and budded viruses (BVs) are morphologically and functionally distinct. ODVs are responsible for primary infection in insect hosts because of their high per os infectivity. On ... -
