Brote de legionelosis en un restaurante de la Comunidad de Madrid

Abstract

Legionella pneumophila serogroup 1 subgroup Pontiac Allentown/France serotype 448 was isolated in water samples, and this Legionella coincided with the one isolated from respiratory samples of some patients. So, we could show the link between environmental risk factor and the disease. This link was also confirmed by genetic sequencing with PCR.

Characterisation of Legionella Clinical Isolates in Spain from 2012 to 2022

“…Allentown/France ST448 was found in seven isolates from clinical samples in the same outbreak [24] and was also described in four sporadic cases.…”

“…The Benidorm subgroup was predominantly represented by the ST42 genotype in 18 isolates, six of which were associated with four outbreaks reported during the studied period, and ST181 was found in 11 isolates, two of which were associated with two independent outbreaks. Allentown/France ST448 was found in seven isolates from clinical samples in the same outbreak [24] and was also described in four sporadic cases.…”

Aspectos a considerar en una actualización de la normativa nacional en materia de legionelosis

“…En los últimos años se han publicado casos de legionelosis asociados a ambientes o instalaciones que parecían tener bajo riesgo, o bien se ha demostrado la presencia de Legionella en los mismos. Se han referido casos asociados a prácticas de nacimiento en medio acuático 60 , humidificadores domésticos 61 , máquinas de hielo 62 , unidades dentales 63 , generadores de niebla usados en supermercados 64 , camiones cisterna de riego de vías públicas 33 , lavaderos de coche y túneles de autolavado 65 y establecimientos de restauración que contaban con diversos equipos de enfriamiento 35 . En los últimos años han proliferado equipos de enfriamiento evaporativo con sistemas de pulverización/nebulización de agua mediante boquillas, utilizados para crear microclimas durante los meses cálidos en ambientes externos establecimientos de restauración 66 .…”

Long‐term monitoring of the microbial quality and Legionnaires' disease risk in tap water from mass catering establishments

“…One of these components is L. pneumophila . Various studies conducted in Spain (Sanz et al, 2014), Japan (Kuroki et al, 2017), the United States (Craun et al, 2010) and Turkey (Sepin Özen et al, 2017) show that tap water causes LD cases and death. The studies on L. pneumophila have been conducted at homes (Akkaya & Özbal, 2011), hotel water supply systems (Doménech‐Sánchez et al, 2022; Valciņa et al, 2023), air conditioning systems (Kirecci & Daglı, 2019), storage tanks and cooling towers (Logan‐Jackson & Rose, 2022) and healthcare services (Chaudhry et al, 2017; Sakhaee et al, 2022).…”
