contamination of room Door Handles by methicillin sensitive methicillin resistant staphylococcus aureus
Journal of Hospital Infection, 2002Co-Authors: Shigeharu Oie, I. Hosokawa, Akira KamiyaAbstract:We investigated the contamination of room Door Handles by Staphylococcus aureus in wards of a university hospital. Door Handles in 53 (27.0%) of 196 rooms were contaminated by methicillin-sensitive Staphylococcus aureus (MSSA) and/or methicillin-resistant Staphylococcus aureus (MRSA); MSSA was detected on Door Handles of 41 rooms (20.9%), MRSA on Door Handles of 17 rooms (8.7%), and MSSA and MRSA on the same Door Handles of five rooms (2.6%). The density of MSSA contamination was 1-2.6x10(4) colony forming units (cfu)/Door handle, and that of MRSA was 1-6.0x10(3) cfu/Door handle. The MRSA contamination rate on Door Handles of rooms with patients with MRSA was 19.0% (4/21 rooms) while that on Door Handles of rooms with patients without MRSA was 7.4% (13/175); the difference was not significant. These results suggest extensive contamination of MSSA and MRSA in the hospital environment.

Prevalence and pattern of antibiotic resistance of Staphylococcus aureus isolated from Door Handles and other points of contact in public hospitals in Ghana.
Antimicrobial resistance and infection control, 2017Co-Authors: Courage Kosi Setsoafia Saba, Jean Kwadwo Amenyona, Stephen Wilson KpordzeAbstract:Studies have implicated Staphylococcus aureus as the leading cause of septicemia in the Tamale metropolis of Ghana. The aim of this study was to determine the prevalence and antibiotic susceptibility of S. aureus and Methicillin Resistant S. aureus (MRSA) in the environments of three hospitals in Ghana. A total of 120 swab samples were taken from Door Handles, stair railings and other points of contact at Tamale Teaching Hospital, Tamale Central Hospital and Tamale West Hospital. The swab samples were directly plated on Mannitol Salt and Baird Parker agar plates and incubated at 37 °C (± 2) for 18–24 h. An antibiotic susceptibility test was performed using the Clinical Laboratory Standard Institute’s guidelines. Isolates resistant to both cefoxitin and oxacillin were considered to be MRSA. A total of 47 (39%) positive S. aureus samples were isolated from all three hospitals, of which, eight (17%) were putative MRSA isolates. One MRSA isolate was resistant to all the antibiotics used (cefoxitin, oxacillin, ciprofloxacin, erythromycin, tetracycline, ampicillin, streptomycin and sulfamethoxazole-trimethoprim). Five of the MRSA isolates were multi-drug resistant, whilst the other three were resistant to only two antibiotics. All the multi-drug resistant MRSA isolates were resistant to at least four antibiotics. The percentage of isolates resistant to oxacillin, ampicillin, ciprofloxacin, tetracycline, streptomycin, erythromycin, and sulfamethoxazole/trimethoprim were 17, 13, 9, 28, 89, 13 and 11% respectively. The high multi-drug resistance of MRSA in hospital environments in Ghana reinforces the need for the effective and routine cleaning of Door Handles in hospitals. Further investigation is required to understand whether S. aureus from Door Handles could be the possible causes of nosocomial diseases in the hospitals.

Antibiotic Susceptibility Profile of Bacteria Isolated from Door Handles of University of Benin Teaching Hospital, Benin City, Edo State, Nigeria
Journal of Health and Environmental Research, 2018Co-Authors: Augustine Brian Odigie, Frederick Osaro Ekhaise, Paul Ikechukwu Orjiakor, Eze Chibuzor Nwadibe, Odeyemi Adebowale Toba, Odoh Chuks KennethAbstract:In recent times, surfaces of hospital environment, constantly exposed to activities of patients and health-care workers, have been identified as potential routes for horizontal dissemination of drug resistant microorganisms of public health significance. This study was conducted to investigate the antibiotic resistance profile of bacteria isolated from samples collected from Door Handles of various units in University of Benin Teaching Hospital (UBTH), Benin City, Edo State, Nigeria. Out of the 66 Door Handles sampled and analysed bacteriologically, 68 predominant bacteria distributed among five (5) species of Escherichia coli (30.9%), Staphylococcusaureus (26.5%), Pseudomonas aeruginosa (17.6%), Streptococcus pneumonia (13.2%) and Bacillus subtilis (11.8%) were isolated. Kirby Bauer techniques of disk diffusion antibiotic susceptibility test on the isolates using 9 commercial antibiotics according to Clinical Laboratory Standards Institute (CLSI) procedure showed resistance of P. aeruginosa to five (5) drugs (Sulfamethoxazole-Trimethoprim, Streptomycin, Ampicillin, Cephalexin and Nalidixic acid), E. coli to five (5) drugs (Ofloxacin, Sulfamethoxazole-Trimethoprim, Ampicillin, Cephalexin and Nalidixic acid), S. pneumoniaeto two drugs (Ampicilin and Nalidixic acid) and S aureus to only Nalidixic acid. Agarose gel electrophoresis carried out on their plasmid DNA revealed detectable fragments in P. aeruginosa and E. coli. After plasmid curing, the isolates became sensitive to Streptomycin, Cephalexin,Ofloxacin, Sulfamethoxazole-Trimethoprim, Ampicillin and Ciprofloxacin. Findings from this study suggest the presence of plasmid mediated multi-drug resistant P. aeruginosa and E. coli on surfaces of hospital Door Handles. Hence, public education on proper personal hygiene and disinfection techniques are recommended in hospitals.

the role of Door Handles in the spread of microorganisms of public health consequences in university of benin teaching hospital ubth benin city edo state
Pharmaceutical Science and Technology, 2017Co-Authors: Augustine Brian Odigie, Paul Ikechukwu Orjiakor, Frederick Osaro Ekhiase, Sunday OmozuwaAbstract:This study was aimed at investigating the microbial loads of surfaces of Door Handles at University of Benin Teaching Hospital (UBTH) with a view to understanding their roles in the transmission of pathogenic microorganisms. Eleven (11) sampling units were identified and used for the study. They included: Emergency Ward, Paediatric Ward, Male and Female Surgical Ward, Intensive Care Unit, Theatre Ward, Consultancy Outpatient Department (COPD), Microbiological Laboratory, Revenue Section, Pharmacy Department, and General Toilet. The samples were collected with the aid of sterile swab sticks moistened with sterile normal saline for a period of Six Months (May 2015 – October 2015) and analyzed using standard microbiological methods. Surfaces of Door Handles of General toilet, Paediatric Ward and Theatre Ward generally had the highest viable bacterial counts, which ranged from 4.03 ± 0.32 - 4.17 ± 0.27 × 104cfu/cm2, while the Intensive Care Unit, Male Surgical Ward and Microbiological Laboratory recorded the least bacterial load that ranged from 3.03± 0.03 - 3.30 ± 0.21 × 104cfu/cm2. The bacterial isolates were Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus pneumoniae, Bacillus subtilis, and Escherichia coli. The most predominant bacterial isolate was E. coli (92.00%), while B. subtilis (60.01%) was the least. Statistical analysis revealed significant correlation (p<0.05) between bacterial isolates and Door Handles at different sampling units. Findings from this study suggest that hospital Door Handles harbor a significant variety of pathogenic and non-pathogenic microorganisms of public health value, and thus could act as potential fomites for communicable diseases dissemination. Health-care workers, patients and visitors are encouraged to pay greater attention to personal hygiene practices to avoid the incidence and spread of hospital acquired infections.

a wearable assistive technology for the visually impaired with Door knob detection and real time feedback for hand to handle manipulation
International Conference on Computer Vision, 2017Co-Authors: Liang Niu, Cheng Qian, John Ross Rizzo, Todd E Hudson, Shane Enright, Eliot Sperling, Kyle Conti, Edward K Wong, Yi FangAbstract:The visually impaired are consistently faced with mobility restrictions due to the lack of truly accessible environments. Even in structured settings, people with low vision may still have trouble navigating efficiently and safely due to hallway and threshold ambiguity. Assistive technologies that are currently available do not provide Door and Door-handle object detections nor do they concretely help the visually impaired reaching towards the object. In this paper, we propose an AI-driven wearable assistive technology that integrates Door handle detection, user's real-time hand position in relation to this targeted object, and audio feedback for "joy stick-like command" for acquisition of the target and subsequent hand-to-handle manipulation. When fully envisioned, this platform will help end users locate Doors and Door Handles and reach them with feedback, enabling them to travel safely and efficiently when navigating through environments with thresholds. Compared to the usual computer vision models, the one proposed in this paper requires significantly fewer computational resources, which allows it to pair with a stereoscopic camera running on a small graphics processing unit (GPU). This permits us to take advantage of its convenient portability. We also introduce a dataset containing different types of Door Handles and Door knobs with bounding-box annotations, which can be used for training and testing in future research.
