ABSTRACT

The frequencies of Escherichia coli, Staphylococcus aureus and Methicillin-resistant S. aureus (MRSA) and ‘aerobic mesophilic bacteria’ (AMB) counts in different seasons and marine sources were compared to understand the microbiological dynamics at beaches in N. Cyprus. Also, antibiotic resistance patterns were evaluated. The characterization and AMB enumeration studies were performed by conventional microbiological methods. AMB counts increased from winter to summer significantly (45.5*104 CFU/mL to 2.5*106 CFU/mL). Similarly, percentage detection frequencies of the bacteria were higher in summer compared to winter and were significant particularly for E. coli in both sand and seawater samples in 2019 and 2020 (p = 0.0181, p = 0.0142, p = 0.1257, p = 0.0446, respectively). However, a significant difference was not detected in percentage detection frequencies in terms of different sources or recreational status of beaches. The highest resistance percentages were detected against beta-lactam and lincosamides group of antibiotics. Results of the study signified that regular microbiological monitoring for beaches is essential.

在两年内监测来自休闲和非休闲海滩的海滩沙子和海水样本中的微生物动态

摘要

比较不同季节和海洋来源的大肠杆菌、金黄色葡萄球菌和耐甲氧西林金黄色葡萄球菌(MRSA) 和“需氧嗜温细菌” (AMB) 计数的频率,以了解塞浦路斯北部海滩的微生物动态。此外,还评估了抗生素耐药性模式。通过常规微生物学方法进行表征和AMB计数研究。AMB 计数从冬季到夏季显着增加(45.5*10 4 CFU/mL 至 2.5*10 6 CFU/mL)。同样,与冬季相比,夏季细菌的百分比检测频率更高,尤其是大肠杆菌。在 2019 年和 2020 年的沙子和海水样品中(分别为p = 0.0181 、p = 0.0142 、p = 0.1257、p = 0.0446)。然而,就不同来源或海滩的娱乐状况而言,百分比检测频率没有发现显着差异。对β-内酰胺和林可酰胺类抗生素的耐药率最高。研究结果表明,定期对海滩进行微生物监测至关重要。
