Objectives: The SARS-CoV-2 pandemic required the use of personal protective equipment (PPE) in medical and social contexts to reduce exposure and prevent pathogen transmission. This study aims to analyse possible changes in voice and speech parameters with and without PPE.
Methods: Speech samples using different types of PPE were obtained.
Background: Candidate Phyla Radiation (CPR) is a large monophyletic group encompassing about 25% of bacterial diversity. Among CPR, "Candidatus Saccharibacteria" is one of the most clinically relevant phyla. Indeed, it is enriched in the oral microbiota of subjects suffering from immune-mediated disorders and it has been found to have immunomodulatory activities.

- * During this period, 39 plague cases were identified, with 29 resulting in death, highlighting serious issues in public health record-keeping as some deaths were misattributed.
- * The research suggests that the spread of the plague in late 1629 was contained more by environmental conditions than by health interventions, despite political efforts to downplay the situation.
Forensic microbiology is a relatively new discipline, born in part thanks to the development of advanced methodologies for the detection, identification and characterization of microorganisms, and also in relation to the growing impact of infectious diseases of iatrogenic origin. Indeed, the increased application of medical practices, such as transplants, which require immunosuppressive treatments, and the growing demand for prosthetic installations, associated with an increasing threat of antimicrobial resistance, have led to a rise in the number of infections of iatrogenic origin, which entails important medico-legal issues. On the other hand, the possibility of detecting minimal amounts of microorganisms, even in the form of residual traces (e.

- Bacterial species, like Serratia marcescens, often develop distinct lineages due to genetic isolation and ecological differences, but the relationship between these factors is not fully understood.
- This study examines the genetic and ecological influences on Serratia marcescens, revealing five well-defined genetic clusters with limited gene sharing, influenced in part by R-M systems compatibility.
- Additionally, investigations into metagenomic datasets indicate only some habitat separation among these clusters, suggesting that genetic isolation is a key factor that occurred before ecological adaptations, aligning with the principles of the Evolutionary Extended Synthesis.
