Antimicrobial Photodynamic Activity of the Zn(II) Phthalocyanine RLP068/Cl Versus Antimicrobial-Resistant Priority Pathogens.

The emergence and spread of antimicrobial resistance among pathogens are significantly reducing available therapeutic options, highlighting the urgent need for novel and complementary treatment strategies. Antimicrobial photodynamic therapy (aPDT) is a promising alternative approach that can overcome antimicrobial resistance through a multitarget mechanism of action, exerting direct bactericidal and fungicidal effects with minimal risk of resistance development. Although aPDT has shown efficacy against a variety of pathogens, data on its activity against large collections of clinical multidrug-resistant strains are still limited.

Molecular Assays on Cutaneous Swabs as an Effective, Non-Invasive Diagnostic Technique for Cutaneous Leishmaniasis: Results from a Retrospective Study Conducted in Italy.

Background: The case confirmation of CL relies on the direct demonstration of the parasite in clinical specimens from skin tissues. Despite most research efforts focusing on biopsy samples as the preferred diagnostic specimen for the detection of spp., the use of non-invasive sampling, such as cutaneous swabs, combined with the use of molecular assays, has shown promising results.

Evaluation of STANDARD™ M10 SARS-CoV-2 from bronchoalveolar lavage samples.

Detection of SARS-CoV-2 in bronchoalveolar lavage (BAL) is considered as a promising alternative method to detect COVID-19 infection. STANDARD™ M10 SARS-CoV-2 assay on 150 negative and 50 positives BAL samples for SARS-CoV-2 showed 96 % sensitivity, 100 % specificity compared to Allplex™ SARS-CoV-2 assay and a 31.25 genomic copies/mL limit of detection.

producing FIM-1-metallo-β-lactamase: emergence and cross-transmission in a long-term acute care rehabilitation hospital.

FIM-1 metallo-β-lactamase was previously detected in sporadic clinical isolates. Here, we report on FIM-1-positive from two patients who had shared the same ward in a long-term acute care rehabilitation hospital. Whole-genome sequencing analysis revealed close relatedness of these isolates, which belonged to an ST235 sublineage (clade 8/14) different from those previously reported.

Utility of bronchoalveolar lavage for COVID-19: a perspective from the Dragon consortium.

Diagnosing COVID-19 and treating its complications remains a challenge. This review reflects the perspective of some of the Dragon (IMI 2-call 21, #101005122) research consortium collaborators on the utility of bronchoalveolar lavage (BAL) in COVID-19. BAL has been proposed as a potentially useful diagnostic tool to increase COVID-19 diagnosis sensitivity.

Carbapenem-resistant : the role of plasmids in emergence, dissemination, and evolution of a major clinical challenge.

Introduction: is a major agent of healthcare-associated infections and a cause of some community-acquired infections, including severe bacteremic infections associated with metastatic abscesses in liver and other organs. Clinical relevance is compounded by its outstanding propensity to evolve antibiotic resistance. In particular, the emergence and dissemination of carbapenem resistance in has posed a major challenge due to the few residual treatment options, which have only recently been expanded by some new agents.

Novel resistance ICEs carrying the metallo-β-lactamase gene from an ST235 sublineage.

FIM-1 is an acquired metallo-β-lactamase identified in a multidrug-resistant (index strain FI-14/157) of clinical origin isolated in 2007 in Florence, Italy. Here we report on a second case of infection by FIM-1-positive (FI-17645), which occurred in 2020 in the same hospital. Both FIM-1-positive strains exhibited resistance to all anti- antibiotics except colistin and cefiderocol.

Material And Methods: Sexually active men with previous severe acute respiratory syndrome coronavirus 2 infection and proven recovery from coronavirus disease 2019 were enrolled in a prospective cohort study. Clinical, uro-andrological data and semen specimens were prospectively collected.

Rapid screening for SARS-CoV-2 VOC-Alpha (202012/01, B.1.1.7) using the Allplex™ SARS-CoV-2/FluA/FluB/RSV Assay.

Background: The emergence of SARS-CoV-2 variants of concern (VOCs) for increased transmissibility and being potentially capable of immune-escape mandates for epidemiological surveillance. Genomic alterations present in VOCs can affect the results of RT-qPCR assays for routine diagnostic purposes, leading to peculiar profiles that can be used for rapid screening of variants. This study reports a peculiar profile observed with the Allplex™ SARS-CoV-2/FluA/FluB/RSV assay and VOC-Alpha (202012/01, lineage B.

Soccer in the time of COVID-19: 1 year report from an Italian top league club, March 2020-February 2021.

We report the events of an Italian top league soccer club that took place in 1 year (from March 2020 to February 2021) at the time of coronavirus disease 2019 (COVID-19) pandemic. In early March 2020, just before sport competitions were called off due to the national lockdown in Italy, the team, which included 27 players and 26 staff at the time, faced a COVID-19 outbreak, with 16 confirmed and seven probable cases, including three staff members who had to be hospitalised. In May 2020, at the resumption of the training sessions, a high prevalence of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin G positivity (35/53, 66%) was detected among the members of the group.

The SARS-CoV-2 viral load in COVID-19 patients is lower on face mask filters than on nasopharyngeal swabs.

Face masks and personal respirators are used to curb the transmission of SARS-CoV-2 in respiratory droplets; filters embedded in some personal protective equipment could be used as a non-invasive sample source for applications, including at-home testing, but information is needed about whether filters are suited to capture viral particles for SARS-CoV-2 detection. In this study, we generated inactivated virus-laden aerosols of 0.3-2 microns in diameter (0.

Summary of the Available Molecular Methods for Detection of SARS-CoV-2 during the Ongoing Pandemic.

Since early 2020, the COVID-19 pandemic has caused an excess in morbidity and mortality rates worldwide. Containment strategies rely firstly on rapid and sensitive laboratory diagnosis, with molecular detection of the viral genome in respiratory samples being the gold standard. The reliability of diagnostic protocols could be affected by SARS-CoV-2 genetic variability.

Antibacterial and Anti-Inflammatory Activity of an Antimicrobial Peptide Synthesized with D Amino Acids.

The peptide SET-M33 is a molecule synthesized in tetra-branched form which is being developed as a new antibiotic against Gram-negative bacteria. Its isomeric form with D amino acids instead of the L version (SET-M33D) is also able to kill Gram-positive bacteria because of its higher resistance to bacterial proteases (Falciani et al., , 2012, 7, e46259).

An antimicrobial molecule mitigates signs of sepsis in vivo and eradicates infections from lung tissue.

The peptide sequence KKIRVRLSA was synthesized in a dimeric structure (SET-M33DIM) and evaluated as a candidate drug for infections due to multidrug-resistant (MDR) Gram-negative pathogens. SET-M33DIM showed significant antibacterial activity against MDR strains of Klebsiella pneumoniae, Acinetobacter baumannii, and Escherichia coli (Minimal Inhibitory Concentration [MICs], 1.5-11 µM), and less activity against Pseudomonas aeruginosa (MICs, 11-22 µM).
