Predominance of hypervirulent clade 8 among STEC strains in Paraguay.

Antimicrobial resistance mechanisms were observed in highly pathogenic strains.

O157:H7 STEC are genotypically diverse and are spread among different clusters.

Glyphosate-based herbicides (GBH) and ciprofloxacin (CIP) alter tadpoles microbiota.

GBH increase taxa diversity and abundance of fast-growing enteric bacteria.

CIP exposure reduced taxa diversity and increase dominance of Aeromonas spp.

GBH-CIP mixture treatment also cause dysbiosis of bacteria from tadpoles microbiota.

Molecular diagnosis made it possible to identify human Orf infection.

Phylogenetic analysis based on 4 ORFV genes.

First molecular comparison of human ORFV strains from Argentina and Chile.

Reemergence of invasive H. influenzae b disease was observed.

The clon ST-6 was the most frequent.

Laboratory surveillance is essential.

SARS-CoV-2 viral load quantitative data in children was analyzed.

Symptomatic children had higher viral load compared to asymptomatic children.

Viral load results may help healthcare workers to safely manage infected children.

Clostridioides difficile ALCD3 shows high efficiency in sporulation.

Spores germinate easily in the presence of taurocholate and glycine.

Results suggest high pathogenic potential and spreading of this nosocomial strain.

This is the first report of an isolate belonging to the MLST ST-293 in Argentina.

Durante 2016-2021 fueron confirmados 12 de los 93 casos de neumonía con sospecha de legionelosis.

La prueba del antígeno urinario resultó negativa en 4 de los 12 casos confirmados.

La incorporación de métodos moleculares contribuyó a evitar falsos negativos.

L. pneumophila fue aislada de secreciones respiratorias de 6 pacientes.

We developed a RT-qPCR method that detects all bovine pestiviruses and allows to pool samples.

Bovine pestiviruses RNA was preserved in two types of filter papers up to 12 months.

RNA was stable at room temperature for 6 months in chromatographic paper.

RNA obtained from PI animals was recovered from papers stored up to 12 months.

Relevant microbial community was still present on kefir after one year of storage.

Bacteria and yeasts were more numerous in kefir grains compared with beverage.

Lentilactobacillus hilgardii, Lentilactobacillus buchneri and Saccharomyces cerevisiae were identified in water kefir.

Water kefir may be an innovative source of potential probiotic strains for bee nutrition.

Study focused on two abattoirs without HACCP plan from Tucumán, Argentina.

Risk estimation showed a marked predominance of high risk in both abattoirs.

Differences of indicator microorganisms between abattoirs were not significant.

Salmonella spp. and STEC were isolated from carcass and environmental samples.

The need to work with authority in search of a standard remains unaddressed.

Candida albicans is the main opportunistic fungus of humans.

Eno1, Pgk1 and Als1 of C. albicans have significant immunogenicity.

Virulence factors involved in the pathogenesis of C. albicans.
