Abstract：
Public restrooms are often a hub of microbial contamination and the examination of bacterial contamination in these facilities can serve as an important indicator of the transmission of infectious diseases. This study was conducted to determine the prevalence of bacterial contamination in public restrooms based on the economic class of the building. Samples were collected from various spots in 32 restrooms found in 10 shopping malls, classifying them into two categories: upper-end restrooms and lower-end restrooms. The findings showed that the level of contamination was higher in the lower-end restrooms, with the seat being the most contaminated area. The most dominant Gram-positive bacteria were of the coagulase-negative staphylococci species, making up 86% of the identified Gram-positive isolates. The most dominant Gram-negative bacteria identified were Klebsiella pneumoniae (K. pneumoniae) and Pseudomonas aeruginosa (P. aeruginosa). The antibiotic sensitivity test results revealed the presence of multidrug-resistant bacteria among the Gram-positive and negative isolates, including Staphylococcus haemolyticus (S. haemolyticus), Staphylococcus kloosii (S. kloosii), Acinetobacter baumanii (A. baumanii), and P. aeruginosa. In conclusion, the study underscores the significance of monitoring bacterial contamination in public restrooms and the need for measures to reduce the spread of infectious diseases. Further research is crucial to gain a complete understanding of the bacterial contamination in public restrooms and their resistance patterns, to ensure the safety and health of the public. The implementation of improved cleaning practices and hands-free designs in addition to the installation of antimicrobial surfaces in restrooms can help reduce the risk of cross-contamination and prevent the spread of diseases.
摘要：
公共厕所通常是微生物污染的枢纽，对这些设施中细菌污染的检查可以作为传染病传播的重要指标。进行这项研究是为了根据建筑物的经济等级确定公共厕所中细菌污染的患病率。样本是从10个商场中发现的32个洗手间的不同地点收集的，将它们分为两类:高端洗手间和低端洗手间。调查结果显示,低端洗手间的污染程度较高,座椅是受污染最严重的区域。最主要的革兰氏阳性菌是凝固酶阴性葡萄球菌，占已鉴定的革兰氏阳性分离株的86％。鉴定出的最主要的革兰氏阴性菌是肺炎克雷伯菌（K。肺炎)和铜绿假单胞菌(P.铜绿假单胞菌）。抗生素敏感性试验结果显示，革兰氏阳性和阴性分离株中存在多重耐药细菌，包括溶血葡萄球菌(S.溶血)，金黄色葡萄球菌（S.kloosii)，鲍曼不动杆菌（A.baumanii),还有铜绿假单胞菌.总之,这项研究强调了监测公共厕所细菌污染的重要性，以及采取措施减少传染病传播的必要性。进一步的研究对于全面了解公共厕所的细菌污染及其耐药模式至关重要，确保公众的安全和健康。除了在洗手间安装抗菌表面外，实施改进的清洁实践和免提设计可以帮助降低交叉污染的风险并防止疾病传播。
