“…This finding is in agreements with other researchers. [17][18][19] High rate of Staphylococcus epidermidis were also reported in this study. This organism is normally found on skin as normal flora, and this might be the reason for their high rate of growth from the mobile phones in the present study.…”

“…MRSA is particularly important in the medical community, as it has developed resistance to βlactam antibiotics. 17 The present study found that Staphylococcus aureus was the predominant microorganism isolated; this bacterium is very important pathogen and can be transferred through the mobile phone to the public community. This finding is in agreements with other researchers.…”

Background: Cell phones are increasingly becoming an important vector for pathogens, especially when they are combined with unhealthy behaviours that speed up the spread of nosocomial infections. Objectives: This study was conducted to investigate microbial contamination of mobile phones belonging to students of Basrah Medical College, located in the southern region of Iraq. Methods: Samples were collected aseptically with sterile swabs moistened with sterile normal saline solution over a period of four weeks. One hundred mobile devices were included in this study. The wet swab was rolled over the exposed surfaces of the mobile phones. Results: Of 100 swabs samples, 137 isolates were identified. Of these, Staphylococcus aureus, Staphylococcus epidermidis, and Pseudomonas aeruginosa were the most frequently identified microorganisms, in addition to other important pathogens. Conclusion: This study showed that mobile phones are potential carriers for the spread of many pathogens, and a measure of cleanliness must be introduced to prevent the possibility of cross contamination. It was also revealed that bacteria colonized mobile phones of medical students and the contaminated mobile phones are able to transport microbes that may be able to produce serious disease.

Background and Purpose: Nosocomial infections are a growing problem in many health centers. Cell phones used by the medical staff can act as a vector for nosocomial transmission of microorganisms. This study aimed to investigate the role of cell phones of senior medical students in the spread of nosocomial bacterial infections in Amir-al-Momenin general hospital in Tehran in September 2015. Methods: Thirty medical students were enrolled using convenience sampling method. Demographic data, perspectives, attitudes, phone type, and frequency of cleaning of mobile phones were collected by questionnaires. Samples were taken from the phones using a sterile swab moistened with a nutritive medium in order to assess the possibility of bacterial growth. Results: A total of 53.3 percent of mobile phones were infected. Isolated bacteria were: Staphylococcus epidermidis (26.7%), Nonalbicans Candida (16.7%), Bacillus PSP (13.3%), Micrococcus PSP (10%), non-hemolytic Streptococcus and Enterococcus (each 6.7%), and Klebsiella and Staphylococcus aureus (each 3.3%). Conclusions: Mobile phones can act as potential carriers of nosocomial infections which are significantly higher in male students' phones and in smartphones. So, some restrictions should be applied to their use in sensitive areas of hospitals. Also, due to the significant impact of cleaning mobile phones in reducing the frequency of bacterial contamination, attention to their regular cleaning should be considered.

“…9 Absence of nasal colonization has been shown to be predictive of lack of MRSA involvement in future pulmonary infection. 9-31 Colonization of the nares provides a place for S aureus to conceal from host defenses, which can lead to infection when host defenses are breached (eg, insertion of a catheter or device). Colonization requires 4 prerequisites as described by Wertheim et al 9 (Figure 1).…”

Systematic Review of the Clinical Utility of Methicillin-Resistant Staphylococcus aureus (MRSA) Nasal Screening for MRSA Pneumonia

Objective: To describe the diagnostic performance characteristics of methicillin-resistant Staphylococcus aureus (MRSA) nasal screening for patients with pneumonia. Data Sources: PubMed and Scopus were searched from 1 January 1990 to 12 December 2018 using terms methicillin-resistant Staphylococcus aureus AND (screening OR active surveillance OR surveillance culture OR targeted surveillance OR chromogenic OR PCR OR polymerase chain reaction OR rapid test) AND (nares OR nasal) AND (pneumonia OR respiratory). Study Selection and Data Extraction: Relevant studies in humans and English were considered. Data Synthesis: In all, 19 studies, including 21 790 patients, were included. Nasal screening for MRSA had a high negative predictive value (NPV; 76% to 99.4% for relevant studies) across all types of pneumonia. Time from nasal screening to culture varied across studies. Relevance to Patient Care and Clinical Practice: MRSA nasal screening has a high NPV for MRSA involvement in pneumonia. Utilizing this test for antimicrobial stewardship program (ASP) purposes can provide a valuable tool for reducing unwarranted anti-MRSA agents and may provide additional cost benefits. A cutoff of 7 days between nasal swab and culture or infection onset seems most appropriate for use of this test for anti-MRSA agent de-escalation for ASP purposes. Conclusions: Consideration for the inclusion of the utility of MRSA nasal screening in MRSA pneumonia should be made for future pneumonia and ASP guidelines. Additional studies are warranted to fully evaluate specific pneumonia classifications, culture types, culture timing, and clinical outcomes associated with the use of this test in patients with pneumonia.
