The purpose of this study was to determine the presence of thermophilic Campylobacter spp. and Salmonella spp. in sand from non-EEC standard and EEC standard designated beaches in different locations in the UK and to assess if potentially pathogenic strains were present. Campylobacter spp. were detected in 82/182 (45%) of sand samples and Salmonella spp. in 10/182 (6%). Campylobacter spp. were isolated from 46/92 (50%) of samples from non-EEC standard beaches and 36/90 (40%) from EEC standard beaches. The prevalence of Campylobacter spp. was greater in wet sand from both types of beaches but, surprisingly, more than 30% of samples from dry sand also contained these organisms. The major pathogenic species C. jejuni and C. coli were more prevalent in sand from non-EEC standard beaches. In contrast, C. lari and urease positive thermophilic campylobacters, which are associated with seagulls and other migratory birds, were more prevalent in sand from EEC standard beaches. Campylobacter isolates were further characterized by biotyping and serotyping, which confirmed that strains known to be of types associated with human infections were frequently found in sand on bathing beaches.
本研究的目的是确定英国不同地点非欧盟标准指定海滩和欧盟标准指定海滩沙子中嗜热弯曲杆菌属和沙门氏菌属的存在情况，并评估是否存在潜在致病菌株。在182份沙子样本中，82份（45%）检测到弯曲杆菌属，10份（6%）检测到沙门氏菌属。从非欧盟标准海滩的92份样本中，46份（50%）分离出弯曲杆菌属；从欧盟标准海滩的90份样本中，36份（40%）分离出弯曲杆菌属。两种海滩的湿沙中弯曲杆菌属的检出率更高，但令人惊讶的是，超过30%的干沙样本中也含有这些微生物。主要致病物种空肠弯曲杆菌和结肠弯曲杆菌在非欧盟标准海滩的沙子中更为普遍。相比之下，与海鸥和其他候鸟相关的海鸥弯曲杆菌和脲酶阳性嗜热弯曲杆菌在欧盟标准海滩的沙子中更为普遍。通过生物分型和血清分型对弯曲杆菌分离株进行了进一步鉴定，结果证实，在海水浴场沙滩的沙子中经常发现已知与人类感染相关类型的菌株。
