Highlights
- •
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.

15
Highlights
- •
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.

Effect of glyphosate and ciprofloxacin exposure on enteric bacteria of tadpolesAna P. Cuzziol Boccioni, Guillermo García-Effron, Paola M. Peltzer, Rafael C. Lajmanovich
Rev Argent Microbiol. 2023;55:120-8
12
Highlights
- •
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.

Highlights
- •
A prospective study on STEC-bloody diarrhea was performed in Argentina between October 2018 and June 2019.
- •
Twenty-nine (4.1%) of 714 bloody diarrhea patients aged 1–9 years were STEC-positive.
- •
Four (13.8%) bloody diarrhea cases progressed to HUS 3–9 days after diarrhea onset.
- •
The most common serotypes among BD and HUS cases were O157:H7 and O145:H28.
- •
The prevalent genotypes among BD and HUS cases were stx2a-only or -associated.
