Legionnaires' disease, which is a waterborne disease leading to pneumonia that can result in death, is one of the major health issues today. The study aims to carry out a three-year retrospective review of routine Legionella follow-up analyses in various samples taken mostly from hospitals in the province of Erzurum and nearby provinces, and to discover a the frequency of isolation of the agent and serogroups from each kind of media.
The study included a total of 2,025 water samples taken from hospitals, hotels, Turkish baths and shopping malls in Erzurum,and 13 nearby cities between 2016 and 2018. Samples were filtered by 0.45 μm-diameter membrane filter paper in the Public Health Laboratory of Erzurum and examined for using culture method, according to the criteria set out in ISO 11731-2.
The presence of was found in 65 of the 2,025 water samples taken in hospitals, and in none of 40 samples taken in hotels, Turkish baths and shopping malls. serogroup 2-14 was detected in 46 (70.8%) of 65 samples found positive, whereas serogroup 1 was detected in 18 (27.7%). Furthermore, both the serogroup 2-14 and serogroup 1 were detected simultaneously in one example (1.5%). The first three samples indicate that the highest positivity rates were in hot water taps (11.6%), hot water tanks (6.1%) and shower heads (4.8%).
The Prevalence rat of was found to be quite low compared to other studies conducted in the western regions of Turkey. positivity was found to be higher in the hot water systems of hospitals and related points, compared to the other sample points.
军团病是一种由水传播导致肺炎的疾病，严重时可能导致死亡，是当今主要的健康问题之一。本研究旨在对 2016 年至 2018 年间从埃尔祖鲁姆省及其周边省份的医院等各种来源采集的常规军团菌后续分析进行为期三年的回顾性分析，并确定从各种介质中分离出该病原体及其血清群的频率。
本研究共包括从埃尔祖鲁姆及其周边 13 个城市的医院、酒店、土耳其浴室和购物中心采集的 2025 份水样。在埃尔祖鲁姆公共卫生实验室，用 0.45μm 直径的膜滤纸过滤样本，按照 ISO 11731-2 规定的标准，用培养法进行检测。
在从医院采集的 2025 份水样中，有 65 份水样中存在 ，而在从酒店、土耳其浴室和购物中心采集的 40 份水样中均未检出。在 65 份阳性样本中，检测到 46 份（70.8%）为 血清群 2-14，18 份（27.7%）为 血清群 1。此外，有 1 份样本同时检出 血清群 2-14 和 血清群 1（1.5%）。前三个样本表明，热水龙头（11.6%）、热水箱（6.1%）和淋浴喷头（4.8%）的阳性率最高。
与土耳其西部其他研究相比，该研究发现 的流行率相当低。与其他采样点相比，医院及其相关点的热水系统中 的阳性率更高。
