“…A total of seven antimicrobial resistance patterns of multidrug was observed in 7.3% (13/ 179) of the S. aureus isolates (Table 4). The contamination of MDR S. aureus isolated from home in theis study was consistent to the previous study, which reported MDR S. aureus contamination of hand touched surfaces in University campus in U.S (7.9%, 6/76) [29]. However, the prevalance of MDR S. aureus in this study was less than other studies including 15.4% from raw cow milk, 14.3% from traditional cheese in Iran, 32.0% from pork, 11.7% from chicken, 10.2% from beef in USA supermarkets and retail chains [8,28].…”

“…Nine of 32 isolates were positive for the mecA gene, therefore 5.0% (9/179) starins were determined as MRSA strains. In USA population, colonized with MRSA, is estimated 1.5 and 5.3% of hand touched surfaces in university campus were contaminated by MRSA [28,29]. However, other studies related to the communities reported higher prevalenc of MRSA compared to this study.…”

One-hundred-and-seventy-nine strains, collected from a total of 825 resident and household item samples in Korean homes nationwide, were tested, to survey the spread of antimicrobial-resistant including the methicillin-resistant (MRSA) strain. Antimicrobial resistance to sulfamethoxazole-trimethoprim (0.0%), teicoplanin (0.0%), tetracycline, vancomycin (0.0%,) chloramphenicol (0.0%), ciprofloxacin (1.1%), clindamycin (1.1%), amikacin (2.2%), gentamicin (8.4%), oxacillin (17.9%), erythromycin (21.8%), ampicillin (96.6%) and penicillin (96.6%), was detected by disk diffusion method and 7.3% (13/179) of the antimicrobial-resistant isolates, were multi-drug resistant (resistant to ≥3 antimicrobial classes). Nine of 32 oxacillin-resistant strains, were positive for the gene and identified as MRSA, in 4 residents and 4 loofah samples, by polymerase chain reaction. These findings provide public health information and contribute to preventing circulation of antimicrobial-resistant strains in community settings including healthy homes.

BackgroundStaphylococcus aureus is a common bacterium found in the nose and throat of healthy individuals, and presents risk factors for infection and death. We investigated environmental contamination of fitness facilities with S. aureus in order to determine molecular types and antibiotic susceptibility profiles of contaminates that may be transmitted to facility patrons.MethodsEnvironmental swabs (n = 288) were obtained from several fitness facilities (n = 16) across Northeast Ohio including cross-fit type facilities (n = 4), traditional iron gyms (n = 4), community center-based facilities (n = 5), and hospital-associated facilities (n = 3). Samples were taken from 18 different surfaces at each facility and were processed within 24 h using typical bacteriological methods. Positive isolates were subjected to antibiotic susceptibility testing and molecular characterization (PVL and mecA PCR, and spa typing).ResultsThe overall prevalence of S. aureus on environmental surfaces in the fitness facilities was 38.2% (110/288). The most commonly colonized surfaces were the weight ball (62.5%), cable driven curl bar, and CrossFit box (62.5%), as well as the weight plates (56.3%) and treadmill handle (50%). Interestingly, the bathroom levers and door handles were the least contaminated surfaces in both male and female restroom facilities (18.8%). Community gyms (40.0%) had the highest contamination prevalence among sampled surfaces with CrossFit (38.9%), traditional gyms (38.9%), and hospital associated (33.3%) contaminated less frequently, though the differences were not significant (p = 0.875). The top spa types found overall were t008 (12.7%), t267 (10.0%), t160, t282, t338 (all at 5.5%), t012 and t442 (4.5%), and t002 (3.6%). t008 and t002 was found in all fitness facility types accept Crossfit, with t267 (25%), t548, t377, t189 (all 10.7%) the top spa types found within crossfit. All samples were resistant to benzylpenicillin, with community centers having significantly more strains resistant to oxacillin (52.8%), erythromycin (47%), clindamycin (36%), and ciprofloxacin (19%). Overall, 36.3% of isolates were multidrug resistant.ConclusionsOur pilot study indicates that all facility types were contaminated by S. aureus and MRSA, and that additional studies are needed to characterize the microbiome structure of surfaces at different fitness facility types and the patrons at these facilities.

“…Public buildings are also aggregators of people, with different ages, roles, education, habits, needs and health status, which may influence the hygienic conditions of public places and the transmission of infections between employees and between users (Thapaliya et al 2017;Zhang et al 2018). In this sense, public restrooms play a key role, as confirmed by the recent interest of the scientific literature on hand washing and its positive influence on increasing antibiotic resistance, reducing the transmission of viruses, bacteria and fungi, both in hospital (Patrick and Van Wicklin 2012;Sabino 2016;Schultz and Spronk 2008) and in non-hospital environments (Anderson et al 2008;Gomes et al 2011;Park et al 2010;Savolainen-Kopra et al 2012).…”

Due to the high density of users hosted everyday, public buildings are important producers of waste and emissions of greenhouse gases (GHGs). Public restrooms play an underrated role in waste generation and GHG emissions, especially if paper towels are used as the hand-drying method. The choice of the hand-drying method (i.e., paper towels vs. electrical hand dryers) also affects the economic balance of a public institution, involving costs for the purchase of hand-drying materials/apparatuses, energy and waste disposal. The present paper aims at evaluating the economic and environmental impact of the introduction of electrical hand dryers (alternative scenario) in place of paper towels (reference scenario) in a public building. The paper presents a solid methodology, based on a numerical experiment approach, to identify a decision criterion for establishing the economical convenience of adopting the alternative scenario in public restrooms. Key factors affecting the choice between the proposed alternatives are presented and discussed in a dedicated sensitivity analysis. From the environmental point of view, this study evaluates the impact of each scenario in terms of GHG emissions, related to multiple waste treatment options and different electric grid mixes. Based on the experimental assumptions, the method allowed concluding that the alternative scenario becomes economically convenient when the number of daily usages (N) is > 57 ± 4. The environmental convenience of the alternative scenario is visible even at N < 10. The method here described can be successfully used to support strategic decisions for cost optimization and environmental mitigation in institutional buildings.
