“…Studies have shown that bacterial contamination of mobile phones, computer keyboards, and other hand-held devices may be involved in the spread of multidrug-resistant pathogenic bacteria [1,2,5]. In this study, there was an overall bacterial contamination level of 63.3% to mobile phones and computer keyboards, and bacterial contamination of 83.3% vs. 43.3% was observed for mobile phones vs. computer keyboards, respectively.…”

Globally, mobile phones and computers (laptops and desktops) are indispensable part of human lives for communication, entertainment, and educational purposes. However, there are concerns about the increasing risk of bacterial contamination and antibiotic resistant trends from the surfaces of these devices. This study aims to assess bacterial contamination of mobile phones and computer keyboards and their resistant profile at the University of Ghana, Korle-Bu Campus, Accra. This was a cross-sectional study conducted from March to June 2017 with 240 swabs collected from the surfaces of mobile phones and computer keyboards used by healthcare students. Swabs were cultured on MacConkey, blood, and mannitol salt agar. Bacteria identification was performed with a standard bacteriological method. A total of 91 bacterial isolates were obtained from the devices, and they were tested against 9 commonly used antibiotics by the Kirby–Bauer disc method. The study revealed mobile phones and computer keyboards had contamination levels of 83.3% and 43.3%. Bacteria isolated included Staphylococcus epidermidis (25.4%), Klebsiella spp. (12.9%), Staphylococcus aureus (9.2%), Escherichia coli (6.7%), Pseudomonas spp. (5.4%), Enterobacter cloacae (2.1%), and Enterobacter spp. (1.7%). Overall, 91 bacterial isolates were highly resistant to ampicillin (96.7%) and tetracycline (75.8%) and moderately resistant to chloramphenicol (49.5%) with lower resistance to cefotaxime (18.7%), ceftadizime (14.2%), ciprofloxacin (25.3%), and gentamycin (24.7%). Additionally, 45.1% of isolates were multidrug resistant. Findings from this study revealed mobile phones and computer keyboards of healthcare students in the university were contaminated with pathogenic bacteria. Hence, frequent hand hygiene and disinfection of mobile phones and computer keyboard surfaces is encouraged to minimize the spread of resistant bacteria pathogens.

“…Various studies have proven that these displays are often contaminated with a variety of microorganisms and can therefore contribute to the spread of nosocomial infections [1][2][3]. By far the most frequently identified microorganisms were pathogenic and non-pathogenic staphylococci [2][3][4].…”

“…Several authors investigated the results of chemical disinfectants and ultraviolet radiation [6][7][8] directly applied to the touch screen display. However, the necessary effort leads to the conclusion that it is hardly possible to disinfect all touch screen devices regularly [3] and so the majority of health-care professionals never disinfect their personal smartphones [4].…”

Touch screen displays are potential pathogen reservoirs and involved in the spread of hospital acquired infections. They emit visible light that is known for a weak but proven antimicrobial photoinactivation effect, so the question is whether displays have the potential to disinfect themselves. To test the antimicrobial capacity of touch screen displays, Staphylococcus carnosus are distributed on Samsung tablets and illuminated for up to 36 hours. The average number of colony forming units decreases with time with white light being the most efficient followed by blue, green and red light. Increasing the illumination intensity by a mirror leads to a faster bacterial decrease up to a 90% reduction in 15 hours. A 99.99% reduction of staphylococci should be possible by turning on the display over the weekend.

“…Em adição, o início da década de 1970 foi marcado pelo surgimento de cepas de S. aureus resistentes à meticilina identificadas pela sigla MRSA (Methicillin Resistant Staphylococcus aureus) (9) . Considera-se que o aumento significativo da manipulação de celulares por profissionais da área da saúde dentro dos estabelecimentos de saúde ao longo do dia e o contato íntimo com o aparelho possibilitam a transferência da microbiota residente e transitória da pele para os aparelhos celulares, podendo elevar o risco da transmissão de bactérias patogênicas responsáveis por infecções, como o S. aureus, para pacientes internados (12) . Ademais, evidencia-se que o uso desses equipamentos em UTIs pode trazer riscos adicionais para infecções relacionadas à assistência, uma vez que frequentemente os pacientes desse setor encontram-se em estados de imunodepressão, debilitados e, eventualmente, com a integridade das barreiras primárias comprometidas (10) .…”

Objetivo: isolar e traçar o perfil de resistência de cepas de Staphylococcus isoladas de smartphones de profissionais de saúde da Unidade de Terapia Intensiva em Hospital Universitário. Métodos: estudo experimental, laboratorial e quantitativo. Coletaram-se 27 amostras com swab nas superfícies dos smartphones com tecnologia touchscreen. Colônias típicas de S. aureus em ágar manitol salgado foram submetidas à coloração de Gram, provas da catalase, DNAse e coagulase; após comprovação fenotípica de S. aureus, realizaram-se testes de sensibilidade a antimicrobianos por técnica de difusão em discos. Utilizou-se análise estatística descritiva. Resultados: identificou-se o crescimento em 21 amostras semeadas em ágar manitol salgado. Destas, 100% pertenciam ao gênero Staphylococcus, 28% apresentavam correspondência ao S. aureus a partir de análise fenotípica e 71,5% (15) a estafilococos coagulase-negativa. As principais resistências microbianas detectadas foram à azitromicinna e à eritromicina. Conclusão: smartphones encontram-se colonizados por Staphylococcus sp resistentes, sendo necessárias medidas de controle para esse micro-organismo.
