摘要

摘要这项工作涉及选定的抗生素耐药性细菌在斯洛伐克地表水中的发生。在34份来自河流和静水(水坝、天然湖泊、热水浴池)的地表水中检测了总大肠菌群、耐抗生素大肠杆菌、肠球菌和凝固酶阳性葡萄球菌,其中一些用于休闲游泳。采样时间为2017年夏季(7月和8月)。总大肠菌群的数量范围为1.74 log CFU/10 mL至3.69 log CFU/10mL。每个测试样本中都登记了大肠杆菌。在Hron河的样本中观察到的数字最高。大多数样品含有氨苄青霉素和四环素耐药性细菌。70%的样本中检测到肠球菌,范围从0.78 log CFU/10 mL到3.81 log CFU/10mL。在Váh河中观察到最高数量的肠球菌。对氨苄西林和万古霉素的耐药性高于对环丙沙星和庆大霉素的耐药性。凝固酶阳性葡萄球菌存在于91%的样本中,范围为0.70-3.03 log CFU/10 mL。仅在32%的样本中观察到抗抗生素凝固酶阴性葡萄球菌,主要来自河流。在这些样品中,氯霉素耐药性占主导地位。在三个用于娱乐目的的水样本中,超过了斯洛伐克立法(第308/2012 Coll.号法令)规定的天然游泳池在沐浴季节水质的肠球菌和大肠杆菌限值。

Antibiotic resistant bacteria in surface waters in Slovakia
Abstract This work deals with the occurrence of selected antibiotic resistant bacteria in Slovak surface waters. Total and antibiotic resistant coliform bacteria, enterococci and coagulase positive staphylococci were determined in 34 samples of surface water from rivers and still waters (dams, natural lakes, thermal bath) some of them used for recreational swimming. Sampling was performed during summer season 2017 (July and August). The number of total coliforms ranged from 1.74 log CFU/10 mL to 3.69 log CFU/10 mL. Coliform bacteria were registered in each tested sample. The highest number was observed in the sample from river Hron. Majority of samples contained ampicillin and tetracycline resistant bacteria. Enterococci were determined in 70 % of samples ranging from 0.78 log CFU/10 mL to 3.81 log CFU/10 mL. The highest number of enterococci was observed in river Váh. Ampicillin and vancomycin resistance prevailed over ciprofloxacin and gentamicin resistance. Coagulase positive staphylococci were present in 91 % of samples in the range of 0.70—3.03 log CFU/10 mL. Antibiotic resistant coagulase positive staphylococci were observed only in 32 % of samples, predominantly from rivers. In these samples, chloramphenicol resistance predominated. In three samples of water used for recreational purposes, the limit value for enterococci and E. coli according to Slovak legislation (Decree no. 308/2012 Coll.) for the quality of water in natural swimming pools during bathing season was exceeded.
