Antonella Belén Ledinic, Ana Paula Reyes, Juan Facundo Gómez Cherey, Sandra Noemí Payalef, Agustina Paula Puñal, Mirta Olga Losada, Verónica Andrea Maldonado, Beatriz Elizabeth Perazzi
Rev Argent Microbiol. 2026;58:
Highlights

  • Greater vaginal microbiota unbalance in Cupper Intrauterine Device (IUD-Cu) users.

  • Higher prevalence of bacterial vaginosis and yeasts in IUD-Cu users.

  • Higher prevalence of vaginal inflammatory reaction in IUD-Cu users.

  • Higher prevalence of Lactobacillus crispatus in oral contraceptive pills (OCPs) users.

Dysgonomonas spp. in gastrointestinal pathology
Meritxell Cubero, Manuel Monsonís, Noelia Muñoz, Amadeu Gené-Giralt
Rev Argent Microbiol. 2026;58:
Highlights

  • With altered gut microbiota, Dysgonomonas spp. would be an opportunistic pathogen.

  • IIts proliferation could lead to symptomatic gastroenteritis.

  • IIts pathogenic potential is limited; all cases are mild to moderate.

  • Most documented cases occur in children under 3 years of age.

Impact of spray-dried Lactiplantibacillus plantarum CIDCA 83114 on a murine model of giardiasis
Manuel Teijeiro, Graciela L. De Antoni, Marina A. Golowczyc, Pablo F. Pérez
Rev Argent Microbiol. 2026;58:
Highlights

  • Spray-dried L. plantarum CIDCA 83114 reduces Giardia trophozoite in infected animals.

  • L. plantarum CIDCA 83114 reduces IL-12 gene expression and increases IL-10 expression.

  • Treatment with L. plantarum shifts the gut microbiota during Giardia infection.

Epidemiological and etiological characterization of superficial mycoses in a general hospital in Buenos Aires
Adriana B. Tarzia, Estefania Riera Gerli, Marcela Zambrana Arebalo, María Russo, Norma B. Fernández
Rev Argent Microbiol. 2026;58:
Highlights

  • Dermatophytosis accounted for 91.3% of diagnosed mycoses.

  • The main dermatophytes were Trichophyton rubrum and Trichophyton tonsurans.

  • In adults, the most common presentation was tinea unguium, caused by T. rubrum.

  • In pediatrics the tinea capitis, due to T. tonsurans in children who go to barbershops.

Bloodstream infections in immunocompromised adult patients
Emanuel Ponce, Agostina Bonilla, Carolina Jimena Duffaut Anun, Florencia Yazmín García, Jacqueline Griselda Mariela Gonzalez, Pehuén Fernandez, María Isabel Garzón, Marcela Flavia Medeot, ... Emanuel José Saad
Rev Argent Microbiol. 2026;58:
Highlights

  • Hospital-acquired BSI were linked to multidrug-resistant (MDR) microorganisms.

  • Community cases were more often driven by Escherichia coli, from urinary source.

  • Risk factors for MDR: prolonged hospital stay, prior antibiotic use, surgery.

  • 30-Days mortality was higher among patients with recent COVID-19 infection.

  • These highlight the need for protocols for immunosuppressed patients at risk of BSI.

Burden and diagnostic capacity of intestinal parasitic infections in Argentina: Analysis of national surveillance and laboratory data
Silvana Carnevale, María Fernanda Degese, María Fernanda Martin Aragón, Daniela Elena Guma, Bibiana Alba Ledesma, Carlos Giovacchini
Rev Argent Microbiol. 2026;58:
Highlights

  • First national assessment of intestinal parasitic infections in Argentina.

  • Integration of surveillance and laboratory network data.

  • Protozoa, mainly Blastocystis and Giardia duodenalis, predominate nationwide.

  • Highest burden in children and vulnerable regions.

  • Heterogeneous laboratory capacity, need for molecular tools.

Predictors of rectal carriage of carbapenemase-producing Gram-negative bacteria in general wards: A case–control study
Maximiliano Gabriel Castro, María José Sadonio, Macarena Vicino, Joaquín Coduri Anthonioz Blanc, Ana Paula Amato, Erwin Alexander Rottoli, Manuel Protto, Fernanda Argarañá, ... Sonia Alejandra Gómez
Rev Argent Microbiol. 2026;58:
Highlights

  • Transfer from another hospital and ICU stay within six months predicted CPB carriage.

  • Length of hospitalization and antibiotic use also predicted CPB carriage.

  • 36% of rectal swabs came from patients without ICU or inter-hospital transfer.

  • 16.8% had no hospitalization in six months, lacking conventional risk factors.

  • CPB carriage must be considered in general wards of tertiary care hospitals.

Effects of plant growth-promoting rhizobacteria on the productivity and nutrition of sugarcane under reduced urea fertilization
Julián Esteban Másmela-Mendoza, Yohan Sebastián Mejía-Flórez, Julián Fernando Mateus-Rodríguez
Rev Argent Microbiol. 2026;58:
Highlights

  • Azotobacter and Gluconacetobacter solubilize P from phosphate rock.

  • Azospirillum solubilizes P from tricalcic phosphate.

  • Azospirillum inoculation increases tillering in sugarcane.

  • Seedlings inoculated with Azospirillum show increased stalk weight and sucrose levels.

  • Azospirillum can replace 25–50% of urea while maintaining a positive growth response.
