手机可能是细菌病原体定殖的理想栖息地，尤其是在炎热的气候下，并且可能是传播医院感染的储存库或载体。我们调查了沙特阿拉伯三家医院医护人员手机上的细菌污染情况，并确定了选定细菌的耐药性。对三所医院的 285 名医护人员进行了问卷调查，收集了工作区和卫生间的手机使用情况、手机清洁和共用情况以及对手机作为感染源的认识等信息。在 Vitek 2 Compact 系统（bioMerieux Inc.，美国）上进行筛选以表征细菌分离株。从三家医院采集的 60 份样本中，有 38 份（63.3%）呈阳性，有 38 种细菌分离株（4 种革兰氏阴性菌和 34 种革兰氏阳性菌）。我们发现 38.3% 的手机受到凝固酶阴性葡萄球菌污染，特别是表皮葡萄球菌（10 株分离株）。其他鉴定出的细菌包括金黄色葡萄球菌、人型链球菌、耳炎异球菌、河流弧菌和施氏假单胞菌。药敏试验显示，大多数凝固酶阴性葡萄球菌对青霉素、红霉素和利福平耐药。八个分离株对苯唑西林具有抗药性，特别是表皮葡萄球菌 (3)、人型链球菌 (2) 和沃氏链球菌 (2)。 A.中耳炎，引起急性中耳炎，表现出多重耐药性。一种分离株，一种经证实的异万古霉素中度耐药金黄色葡萄球菌，对常用于治疗皮肤感染的抗生素具有耐药性。污染程度与在厕所和共用手机的使用情况之间存在显着相关性。我们的研究结果强调了医护人员使用手机时的卫生习惯对于防止多重耐药微生物传播的重要性。
Cell phones may be an ideal habitat for colonization by bacterial pathogens, especially in hot climates, and may be a reservoir or vehicle in transmitting nosocomial infections. We investigated bacterial contamination on cell phones of healthcare workers in three hospitals in Saudi Arabia and determined antibacterial resistance of selected bacteria. A questionnaire was submitted to 285 healthcare workers in three hospitals, and information was collected on cell phone usage at the work area and in the toilet, cell phone cleaning and sharing, and awareness of cell phones being a source of infection. Screening on the Vitek 2 Compact system (bioMerieux Inc., USA) was done to characterize bacterial isolates. Of the 60 samples collected from three hospitals, 38 (63.3%) were positive with 38 bacterial isolates (4 Gram-negative and 34 Gram-positive bacteria). We found 38.3% of cell phones were contaminated with coagulase-negative staphylococci, particularly Staphylococcus epidermidis (10 isolates). Other bacterial agents identified were S. aureus, S. hominis, Alloiococcus otitis, Vibrio fluvialis, and Pseudomonas stutzeri. Antimicrobial susceptibility testing showed that most coagulase-negative staphylococci were resistant to benzylpenicillin, erythromycin, and rifampicin. Eight isolates were resistant to oxacillin, specifically S. epidermidis (3), S. hominis (2), and S. warneri (2). A. otitis, a cause of acute otitis media showed multidrug resistance. One isolate, a confirmed hetero-vancomycin intermediate-resistant S. aureus, was resistant to antibiotics, commonly used to treat skin infection. There was a significant correlation between the level of contamination and usage of cell phone at toilet and sharing. Our findings emphasize the importance of hygiene practices in cell phone usage among healthcare workers in preventing the transmission of multidrug-resistant microbes.
