“…For our research, we had chosen the bell and the diaphragm as they come in direct contact with the fingers of HCWs and are applied directly to the patient’s body to receive vibrations from a selected skin surface area and transmit them to the inside of the waveguide. According to the literature data, bacterial colonization of the diaphragm is much more frequent than the colonization of the bell ( Dutra et al 2013 ; Campos-Murguía et al 2014 ; Queiroz Júnior et al 2021 ). It is also confirmed by our results from all tested stethoscopes, regardless of the year of a student’s education.…”

“…In a study by Uneke et al (2008) , S. aureus amounted to 41.6%. According to Queiroz Júnior et al (2021) , 80% to 100% of stethoscopes in use are contaminated with S. aureus , of which 20–40% are resistant to methicillin. As a comparison, in the study by Gazibara et al (2015) , S. aureus was most frequently isolated at 62.64%, of which 21.05% were MRSA isolates.…”

The stethoscope remains an indispensable diagnostic tool for medical students. Improper stethoscope hygiene may cause bacterial infections, including hospital-associated infections (HAIs), which challenge the Polish medical system. The study’s main objective was to evaluate the hygiene habits declared by medical students. Moreover, microbiological control with the characteristics of potentially pathogenic microorganisms was performed. The study included 66 medical students from the Faculty of Medicine at the Jagiellonian University Medical College in Cracow, Poland. The participants filled in an anonymous questionnaire. Stethoscope contamination was assessed through isolation, identification, testing of antibiotic resistance, and clonality of the isolates bacterial pathogens. The survey showed that only 30.3% of students cleaned their stethoscopes after each patient, and 1.5% never did this. Of the 66 stethoscopes tested, 100% were positive for bacterial growth. Staphylococcus spp. was the most frequently isolated contaminant (50.5%). The questionnaire results demonstrated the necessity of the validated procedures for cleaning the stethoscopes. Stethoscopes used by medical students are contaminated with numerous bacterial species, including multidrug-resistant organisms. The clonal structure of the MRSA and MRSE populations acquired from stethoscopes has been demonstrated. Our results confirm the possibility that these medical devices mediate the spread of hazardous pathogens in the hospital environment. Practical exercises are essential to forming the correct hygiene habits involving stethoscopes, which enable practicing and checking the correctness of the established skills.

“…Additionally, mobile medical devices should be included in routine investigations due to their potential for cross-contamination between patients [61]. Ensuring proper disinfection protocols for these devices with proper hand hygiene measures is essential in minimizing the risk of transmission of pathogens, including C. auris [100].…”

Candida auris, a multidrug-resistant yeast, poses significant challenges in healthcare settings worldwide. Understanding its environmental reservoirs is crucial for effective control strategies. This systematic review aimed to review the literature regarding the natural and environmental reservoirs of C. auris. Following the PRISMA guidelines, published studies until October 2023 were searched in three databases: PubMed, Web of Science, and Scopus. Information regarding the origin, sampling procedure, methods for laboratory identification, and antifungal susceptibility was collected and analyzed. Thirty-three studies published between 2016 and 2023 in 15 countries were included and analyzed. C. auris was detected in various environments, including wastewater treatment plants, hospital patient care surfaces, and natural environments such as salt marshes, sand, seawater, estuaries, apples, and dogs. Detection methods varied, with molecular techniques often used alongside culture. Susceptibility profiles revealed resistance patterns. Phylogenetic studies highlight the potential of environmental strains to influence clinical infections. Despite methodological heterogeneity, this review provides valuable information for future research and highlights the need for standardized sampling and detection protocols to mitigate C. auris transmission.

“…Diante de tantos casos de resistência bacteriana, enquanto novas drogas para conter, não acompanha o seu aumento, muitos países lideram campanhas contra seu uso indiscriminado com o objetivo de garantir que os medicamentos sejam usados de forma segura, responsável e que toda a população tenha acesso ao tratamento [3,11]. A resistência condicionada por bomba de efluxo de macrolideos é codificada pelo gene mefA.…”
