Graphical Abstract

Journals increasingly request a “graphical” or “visual abstract” alongside the article. A graphical abstract summarizes your article concisely and professionally to appeal to an interdisciplinary audience. Some authors use a concluding figure, but many create specially designed graphical abstracts to capture content at a glance.

Antibacterial activity and effect on the outer membrane permeability of Apis mellifera honey from Brazil
Rithiely Conceição Silva, Larissa Maria Scalon Lemos, Carla Galbiati
Rev Argent Microbiol. 2026;58:
Highlights

  • Brazilian honey (Midwest) has the antimicrobial activity at Enterococcus faecalis.

  • Brazilian honey increased the membrane permeability of the Enterococcus faecalis.

  • Membrane permeability is probably associated with the flavonoids present in the n-butanol fraction of honey.

Dairy effluent management systems as a potential persistence source of Shiga toxin-producing Escherichia coli (STEC) strains
Jessica Basualdo, Gastón A. Iocoli, Marisa A. Gómez, María Celina Zabaloy
Rev Argent Microbiol. 2025;57:70-7
Highlights

  • The presence of STEC has been confirmed in various types of samples and points in the system.

  • Management practices influence the prevalence of STEC strains in dairy farms.

  • Positive STEC samples increase during spring.

  • Genetic profiles associated with HUS were detected in samples.

  • The high persistence of STEC in sediments is associated with the potential to form biofilm.

Campylobacter fetus releases S-layered and immunoreactive outer membrane vesicles
Pablo Farace, Silvio Cravero, Catalina Taibo, Julián Diodati, Claudia Morsella, Fernando Paolicchi, Julia Sabio y García, Andrea Gioffré
Rev Argent Microbiol. 2022;54:74-80
Highlights

  • Campylobacter fetus produces spontaneously outer membrane vesicles in vitro.

  • S-layer is preserved on the surface of the outer membrane vesicles of C. fetus.
