军团菌被认为是潜在可预防的病态和死亡的最重要原因之一。这些微生物无处不在,但是关于我们地区军团菌物种的地理分布的信息不完整。
由于上述原因,在这项工作中,军团菌的分布。在佩萨罗-乌尔比诺(意大利中部)市区的非医院设施中,包括公共喷泉,住宅建筑,公共和私人办公室和养老院,被调查。
从不同设施收集总共298个水样,并进行标准军团菌分离和鉴定方案。
据报道,收集的水样中有17.8%的军团菌属呈阳性。(28.6%来自养老院,21.3%来自住宅建筑,15.3%来自私人和公共办公室)。在退休房屋(58.8%)和住宅建筑物(31.8%)的热水中,阳性样本的百分比最高(14.4%);最常见的分离血清群是肺炎支原体2-14(71.7%)。
这项工作首次描述了军团菌的分布。在佩萨罗-乌尔比诺省的非医院设施中,并强调了易感类别的潜在风险状况。从我们的数据来看,我们可以指出,定期和持续的控制,以防止军团菌病的微生物风险,特别是在容纳老年人的设施中,是推荐的。
Legionella is considered one of the most important causes of potentially preventable morbid-ity and mortality. These microorganisms are ubiquitous, but incomplete information is available on the geographic distribution of Legionella species in our region.
For the mentioned reasons, in this work the distribution of Legionella spp. in non-hospital facilities of the urban area of Pesaro-Urbino (Central Italy), including public fountains, residential build-ings, public and private offices and retirement homes, was investigated.
A total of 298 water samples were collected from the different facilities and subjected to standard Legionella isolation and identification protocols.
As reported, 17.8% of the collected water samples resulted positive for Legionella spp. (28.6% from retirement homes, 21.3% from residential buildings, 15.3% from private and public offices). The highest per-centage of positive samples (14.4%) was found in hot water from retirements homes (58.8%) and residential buildings (31.8%); the most frequent isolated serogroups were L. pneumophila 2-14 (71.7%).
This work is the first describing the distribution of Legionella spp. in non-hospital facilities in the province of Pesaro-Urbino, and highlights a condition of potential risk for susceptible categories. From our data, we can point that a regular and constant control to prevent microbiological risk from legionellosis, particularly in facilities housing the elderly, is recommended.
