Article Abstract
This is the first study of the genetic diversity of Moraxella spp. Isolates were detected in an Eye Hospital in the City of Buenos Aires. Due to the high frequency of Moraxella spp. observed in corneal abscesses, we decided to validate their identification at the species level, determine their drug susceptibility and perform molecular subtyping. Seventeen (17) isolates obtained from corneal abscesses were evaluated. The identification was carried out using a combination of biochemical tests and MALDI-TOF mass spectrometry. Of these isolates, 88.2% were identified as Moraxella lacunata, and 11.8% as Moraxella nonliquefaciens. Molecular subtyping was performed using the pulsed-field gel electrophoresis (PFGE) technique. All isolates were typable and thirteen digestion patterns were identified. Based on the obtained results, the PFGE technique using the SmaI enzyme can be used for epidemiological studies of strains of these species.

The Grand Magal of Touba (GMT) is the largest religious gathering in West Africa, and, like any large mass gathering, presents a risk of transmission of infectious diseases, mainly respiratory tract infections. Respiratory pathogen carriage was assessed by qPCR between 2017 and 2023 in healthy and ill pilgrims. The study included 1067 pilgrims comprizing 328 healthy controls, 298 pilgrims with respiratory symptoms who did not consult and 441 patients who consulted for respiratory symptoms.

: Acute pediatric rhinosinusitis is most commonly caused by , , and . The involvement of species is rare and typically linked to chronic or nosocomial infections. Typical cases of acute rhinosinusitis in children present with abundant nasal discharge, headache, and fever and are generally managed with systemic antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), mucolytics, and topical intranasal treatment.

Background: The nasopharyngeal microbiota, which plays a crucial role in respiratory health and disease during infancy, was significantly affected by the COVID-19 pandemic lockdown in children and adults. This study aimed to prospectively explore the dynamics of the nasopharyngeal microbiota in infants during the COVID-19 pandemic.
Methods: We conducted a prospective birth cohort study at Hospital Sant Joan de Déu (Barcelona, Spain) involving 32 neonates born between December 2019 and December 2020.

is a recently described Gram-negative bacterium that colonises the human nasopharynx and may be associated with poor upper respiratory tract health. Here, we describe the isolation of from samples collected from a South African birth cohort, creating the first archive of cultured strains of the species from Africa. Sequenced genomes from this archive reveal that South African is more similar to Australian strains than those from Southeast Asia, and that it may share genes with other members of the microbiome that are relevant for virulence, colonisation, and antibiotic resistance.
