AI Article Synopsis
- Salmonellosis is a disease that can affect both animals and humans, often linked to antimicrobial-resistant bacteria found in reptiles that act as carriers.
- The study focused on testing the effectiveness of L. essential oil (TEO) against bacterial growth and biofilm production of these resistant bacteria isolated from reptiles in a Zoo in Italy.
- Results showed that TEO successfully inhibited bacterial growth and biofilm formation at various dilutions, suggesting it could be a useful disinfectant to prevent salmonellosis transmission from reptiles to humans.
Article Abstract
Salmonellosis is an infectious disease affecting both animals and humans. Antimicrobial resistant (AMR) and biofilm-producing spp., frequently detected in reptiles (who can then act as asymptomatic carriers for warm-blooded animals), have developed resistance to biocides; this represents a warning for the emergence of biocide/antimicrobial cross-resistance. The aim of this study was to evaluate the efficacy of L. essential oil (TEO) in inhibiting bacterial growth and biofilm production of spp., which had been isolated from wild reptiles housed in a Zoo in Italy. The resistance profile against different classes of antibiotics showed that all the isolates were susceptible to the tested antibiotics, despite the presence of several AMR genes. All the isolates were also tested with aqueous solutions of TEO at different dilutions (5% to 0.039%). Interestingly, TEO proved effective both in inhibiting bacterial growth at low dilutions, with MIC and MBC values ranging between 0.078% and 0.312%, and in inhibiting biofilm production, with values ranging from 0.039% to 0.156%. TEO demonstrated effective bioactivity against the biofilm producer spp., proving to be a valid disinfectant for the prevention of salmonellosis from reptiles, a possible source of infection for humans exposed to the reptiles' environment.

Aim: This study aimed to assess if the addition of origanum oil to denture materials could decrease microorganisms counts and biofilm formation without changing their mechanical/surface properties.
Materials And Methods: A total of 66 resilient denture liner discs (SoftConfort, Dencril Comércio de Plásticos Ltda, SP, Brazil) were prepared with fixed dimensions of 10 × 3 mm for biofilm assay ( = 36) and 12 × 2 mm for sorption-solubility tests ( = 30) containing three oil concentrations - 0, 2.5 and 5%, thereby = 12 per each group samples for biofilm assay and = 10 per each group for sorption-solubility test respectively.

Dental caries, driven by dysbiosis in oral flora and acid accumulation, pose a significant threat to oral health. Traditional methods of managing dental biofilms using broad-spectrum antimicrobials and fluoride face limitations such as microbial resistance. Natural products, with their antimicrobial properties, present a promising solution for managing dental caries, yet their clinical application faces significant challenges, including low bioavailability, variable efficacy, and patient resistance due to sensory properties.

The degradation of rubber seal (RS), particularly ethylene-propylene-diene (EPDM), in the drinking water networks has been confirmed, yet the role of RS as a disinfection by-product (DBP) precursor remains unknown. This study provides explicit proof of the formation of halogenated disinfection by-products (X-DBPs) from RS in chlorinated drinking water within water supply systems. Over time, exposure to chlorinated water ages RS, releasing high levels of organic compounds, which act as DBP precursors.

This review aimed to assess the scope of the literature on tracking the microbial community of biofilms, focusing on the dairy farm and processing environments. The majority of studies focused on either production, storage, transport or processing of milk, while 5 combined the investigation of both production and processing facilities. Factors influencing short-term changes in dairy microbiota such as the occurrence of mastitis and season were distinguished from factors revealed through long-term studies, such as feed and weather, rather than the milking equipment.

Purpose: Preclinical studies have confirmed the safety and efficacy of narrowband low-intensity ultraviolet C light (UVC) in managing bacterial corneal infection. To further consolidate these findings, the present study aimed to explore in vitro anti-biofilm efficacy of low-intensity UVC light for its potential use in biofilm-related infections.
Methods: Pseudomonas aeruginosa biofilm was grown in chamber well slides for 48 h and exposed to one of the following challenges: UVC (265 nm wavelength, intensity 1.
