Antiseptics' Concentration, Combination, and Exposure Time on Bacterial and Fungal Biofilm Eradication.

Background: This study aims to assess the activity of solutions containing povidone-iodine (PI) and hydrogen peroxide (HO) alone or combined on the biofilm of microbial species in the contest of periprosthetic joint infection (PJI).

Methods: Different antiseptic solutions were tested on 2-day-old biofilms of Gram-positive and Gram-negative bacteria and fungi at 1 and 3 minutes of exposure. The efficacy of these solutions was evaluated by measuring the biofilm metabolic activity by methoxynitrosulfophenyl-tetrazolium carboxanilide (XTT) reduction assay.

Antibacterial Metabolites Produced by an Endemic Plant of Lampedusa Island.

Lampedusa, the largest island of the Pelagie archipelago, Sicily, Italy, has proven to be a rich source of plants and shrubs used in folk medicine. These plants, often native to the island, have been very poorly investigated for their phytochemical composition and biological potential to be translated into pharmacological applications. To start achieving this purpose, a specimen of , a plant native to Lampedusa, was investigated for the first time.

Unveiling the mechanism of action of acylated temporin L analogues against multidrug-resistant .

The increasing resistance of fungi to conventional antifungal drugs has prompted worldwide the search for new compounds. In this work, we investigated the antifungal properties of acylated Temporin L derivatives, and , against , including the multidrug-resistant strains. Acylated peptides resulted to be active both on reference and clinical strains with MIC values ranging from 6.

Extended-Spectrum Beta-Lactamase-Producing and Carbapenem-Resistant in Companion and Animal-Assisted Interventions Dogs.

Animal-assisted interventions (AAIs) are being implemented in many countries for the beneficial effects they have on humans. Patients involved in AAI are often individuals at greater risk of acquiring infections, and these activities involve close contact between humans and animals, as is the case with humans living with a pet. The spread of multidrug-resistant is a serious problem for human health; an integrated One Health strategy is imperative to combat this threat.
