First report of linear megaplasmids in the genus Micrococcus. Plasmid (2009),
(Academic Press Inc Elsevier Science, 2010-12)
High-altitude wetlands (above 4200 m) in the northwest of Argentina are considered pristine and extreme environments. Micrococcus sp. A1, H5, and V7, isolated from such environments, were shown to contain linear megaplasmids, ...
Impact on public health of the spread of high-level resistance to gentamicin and vancomycin in enterococci
(Frontiers Research Foundation, 2018-03)
Antibiotic resistance has turned into a global public health issue. Enterococci are intrinsically resistant to many antimicrobials groups. These bacteria colonize dairy and meat products and integrate the autochthonous ...
Resistance to insecticides and effect of synergists on permethrin toxicity in Pediculus capitis (anoplura: Pediculidae) from Buenos Aires
(Entomological Society of America, 2000-12)
Permethrin-resistant colonies of Pediculus capitis (De Geer) from Buenos Aires were used to establish a resistance profile and to examine resistance mechanisms. All permethrin-resistant head lice (resistance ratio from ...
PncA gene expression and prediction factors on pyrazinamide resistance in Mycobacterium tuberculosis
(Elsevier, 2013)
Mutations in the pyrazinamidase (PZAse) coding gene, pncA, have been considered as the main cause of pyrazinamide (PZA) resistance in Mycobacterium tuberculosis. However, recent studies suggest there is no single mechanism ...
Banana fruits with high content of resistant starch: Effect of genotypes and phosphorus fertilization
(2020-05-01)
Banana fertilization practices aim to increase agricultural yield and the effects of these practices on fruit components have not been well explored. This study aimed to evaluate the effects of phosphate fertilizer levels ...
High level resistance to gentamicin and vancomycin in enterococci isolated from poultry in Argentina
(Paripex-In, 2018-12)
In chicken husbandry, antimicrobial resistance among enterococci has been observed. Glycopeptides and gentamicin MinimumInhibitory Concentrations in fecal poultry enterococci were determined. Glycopeptide and high-level ...
Whole-Genome Sequencing for Drug Resistance Profile Prediction in Mycobacterium tuberculosis
(American Society for Microbiology, 2019)
Whole-genome sequencing allows rapid detection of drug-resistant Mycobacterium tuberculosis isolates. However, the availability of high-quality data linking quantitative phenotypic drug susceptibility testing (DST) and ...
Nematode resistance to ivermectin (630 and 700 mu g/kg) in cattle from the Southeast and South of Brazil
(Elsevier B.V., 2014-12-01)
Two high doses of ivermectin (630 mu g/kg and 700 mu g/kg) that are sold commercially in Brazil were evaluated in dose-and-slaughter trials with 144 naturally nematode-infected cattle from eight regions within the states ...
Multidrug resistance pump AcrAB-TolC is required for high-level, Tet(A)-mediated tetracycline resistance in Escherichia coli
(Oxford University Press, 2006-07)
Objectives: Starting from the observation that Escherichia coli tolC mutations severely reduced the high-level resistance to tetracycline afforded by Tn10- and plasmid-encoded Tet(A) pumps, we studied the mechanism of this ...
