Tested SARS-CoV-2 molecular assays showed good performance and allowed decentralization.

The 9-min RNA extraction was the less time-consuming method yielding quality results.

FlashPrep® reagent showed excellent results to perform direct RNA detection.

Isothermal amplification assays showed acceptable sensibility and specificity.

All the assays were useful for detection of the COVID-19 waves in the central region of Argentina.

Xylaria sp. es capaz de llevar a cabo actividad enzimática nitrilasa.

Una secuencia homóloga de ADN transcribiría enzimas nitrilasas.

La expresión genética es inducible con diversas fuentes de carbono y nitrógeno.

El hongo produce AIA y promueve el desarrollo radicular en Arabidopsis thaliana.

Las enzimas nitrilasas son intermediarias metabólicas de AIA.

P. mirabilis flagella have a medium-dependent role in cellular hydrophobicity.

All motility and catheter migration models showed a significant role of flagella.

A flagellate P. mirabilis mutant was outcompeted by the wild-type in biofilms.

Biofilm formation of the mutant was impaired as seen in different in vitro assays.

Flagellar function could be targeted to prevent biofilm formation.

Los abscesos cerebrales pueden estar relacionados con otitis media crónica.

La espectrometría de masas es útil para identificar A. europaeus.

Se destaca la relevancia de A. euroapeus y su asociación a la localización cerebral.

La peritonitis primaria neumocócica es una manifestación poco frecuente que debe vigilarse.

Se debe considerar la etiología neumocócica, particularmente en pacientes con comorbilidades.

El cultivo, aislamiento y antibiograma permiten instaurar un tratamiento adecuado.

Los perfiles de resistencia muestran sensibilidad a β-lactámicos.

Es escasa la información del impacto de las vacunas en estos cuadros.

We aimed to determine if SARS-COV-2 cycle threshold could predict mortality.

We included 35 patients with hematologic malignancies with COVID-19.

Cycle threshold was lower in the patients who died compared with the survivors.

SARS-COV-2 cycle threshold predicted mortality in this population.

Serratia marcescens represents a nosocomial pathogen worldwide.

First description of a nosocomial outbreak by SME-4 in South America.

Class A carbapenemases different from KPC may be underestimated.

A. argentinense Az19 mitigated maize growth reduction due to water deficit (WD) at V2.

WD at flowering reduced maize yield less in Az19- than in Az39-inoculated plants.

Az19 is a promising PGPR strain to be used as an inoculant in areas subjected to WD.

We observe in the strains from foods a higher production of biofilms in PVC.

In the BHI broth, no submerged biofilms were found.

The enterotoxin profile most common includes genes for the three enterotoxins.

Ureaplasma sp.–Ureaplasma diversum were detected in 17.1% of pig lungs.

Ureaplasma sp.–U. diversum and M. hyopneumoniae were detected in 12.5% of lungs.

In the 27.3% of EP-like lesions Ureaplasma sp.–Ureaplasma diversum were detected.

Aspirin or statins through pro-resolving lipids may improve inflammation in parasitosis.

Statins in cerebral malaria reduce mortality in murine models of infection.

In toxoplasmosis, statin use is controversial, although it decreases cytokines.

In leishmaniasis, statins decrease local inflammation.

In Chagas disease, aspirin or statins decrease cardiac inflammation in murine models.
