  • Bacterial co-pathogens are commonly identified in viral respiratory infections.

  • Co-infection between C. pneumoniae and SARS-CoV-2 has been reported in the literature.

  • Information of co-infection in COVID-19 patients is scarce.

  • Evidence of co-infections is needed to support developing skills in antimicrobial policy.

Study of the genetic diversity of Moraxella spp. isolates obtained from corneal abscesses
Karina L. Roitman, Lucía Cipolla, Patricia Minervini, Mónica Prieto
10.1016/j.ram.2022.03.004
Highlights

  • MALDI-TOF MS is a reliable tool for identifying M. lacunata and M. nonliquefaciens.

  • Using SmaI as restriction enzyme, PFGE is a useful technique for typing Moraxella species.

  • Antibiotic susceptibility testing for M. lacunata is not standardized by the CLSI.

Clostridioides difficile: Characterization of the circulating toxinotypes in an Argentinean public hospital
Andrea N. Crivaro, Paula Carasi, Ileana Salto, Ayelen Hugo, P. Cecilia Soldavini Pelichotti, Agustina Bengoa, Melisa Fragomeno, María A. Serradell, Jessica Minnaard, Ivanna Rolny, Eduardo Alul, Leandro Arregui, Macarena E. Fabra Martinez, Oscar Javier Moreno Valero, Andrea Facente, Francisco Magariños, Virginia Jewtuchowicz, Pablo F. Pérez, Fernando M. Trejo
10.1016/j.ram.2022.05.010
Highlights

  • Toxinotypes 0, I and VIII circulate in the same hospital.

  • Toxinotype VIII is the most prevalent.

  • Occurrence of toxinotype I (one isolate) is compatible with the introduction of microorganisms from external sources.

  • Isolates associated to fatal outcomes (GCD13, GCD14 and GCD22) are situated in regions of the biplots related to altered laboratory values at admission.

10.1016/j.ram.2022.02.007
Highlights

  • Epidemiologic and spatial analysis of leptospirosis can be applied in human population.

  • Information about leptospirosis in rural areas is scarce.

  • Preventive measures can be applied for human leptospirosis from rural areas.

Helicobacter pylori infection: A balance between bacteria and host
Pamela Bucci, Yanina Barbaglia, Fabián Tedeschi, Fabián Zalazar
10.1016/j.ram.2022.04.003
Highlights

  • H. pylori genotypes and SNP-174G>C IL-6 in patients with gastritis were evaluated.

  • More virulent genotypes and -174G/G IL-6 were found in active chronic gastritis IM+.

  • Our results can be useful to identify patients at greater risk for adenocarcinoma.

Phenotypic and molecular characterization of Staphylococcus aureus isolates conducted in nares of psoriatic patients attending a public hospital in Argentina
Carina A. Boncompain, Cristian A. Suárez, Mario Squeff, Valeria Belluzo, Gustavo Piccirilli, Ana Molteni, Ramón A. Fernández Bussy, Héctor R. Morbidoni
10.1016/j.ram.2022.02.008
Highlights

  • A study on the carriage of Staphylococcus aureus in psoriasis patients is presented.

  • Carriage was higher in the group of psoriasis patients than in the control group.

  • The frequency of isolation was directly related to the severity of the disease.

  • No link of phenotypic or virulence trait of S. aureus to psoriasis was found.

  • Transcriptomics will answer if specific S. aureus genes are linked to psoriasis.

10.1016/j.ram.2022.04.002
Highlights

  • Klebsiella pneumoniae ST307 resistant to carbapenems and ceftazidime/avibactam.

  • KPC-3 and NDM-1 producing Klebsiella pneumoniae isolates are clonally related.

  • blaNDM-1 is located in a conjugative IncA/C plasmid.

  • Genetic context of blaNDM-1 presented ISKpn14 and bleMBL.
