    Opis:
    Background: Legionella spp. have been found in both natural and manmade water systems, coastal waters, thermal waters, moist soils, clays, and near wastewater discharge sites. Aim of the study: This study aims to report a comparative, retrospective epidemiological analysis of water testing study results indicating the presence of Legionella spp. in Poland between 2009-2013 and 2014-2016. This study is a comparative retrospective epidemiological analysis of individual tests for the presence of Legionella spp. in hotels between two different time periods. The two time periods being compared in this study are between 2009-2013 (n=369 hotels) and 2014-2016 (n=174 hotels). Reporting has been performed in accordance with the STROBE checklist. Material and methods: Hot water samples were collected by employees of the Sanitary and Epidemiological Station in Poland as part of routine water quality monitoring. Samples were taken from the water supply systems of 369 hotels, representing 19.59% of total hotels in Poland, from January 2009 until December 2013. Samples were taken from the water supply systems of 174 hotels, representing 7.51% of total hotels in Poland, from January 2014 until December 2016. Results: The percentage of facilities classified as Group I remained comparable for the period between 2009 and 2013 compared to the period between 2014 and 2016. The percentage of facilities classified as Group II, however, showed a clear upward trend between 2014 and 2016 compared to the time period between 2009 and 2013. The percentage of facilities classified as Group III showed a clear downward trend between 2014 and 2016 compared to the time period between 2009 and 2013. Conclusions: The colonization rates observed in this comparative study indicate that the aquatic environment in these facilities requires constant monitoring to lower the risk of legionellosis. The increased colonization of hotel water networks with Legionella spp. is a serious health problem that requires constant monitoring.

    Opis:
    Introduction. The increasing development of marine traffic has led to a rise in the incidence of legionellosis among travellers. It occurs in similar environments, especially closed and crowded, and aboard ships Legionella survives and multiplies easily in water pipes, spreading into the environment through air conditioning systems and water distribution points. Although in recent years in the construction of cruise ships preventive measures aimed at curbing the proliferation of Legionella (design, materials, focus on the operation and maintenance of the water system), have been taken account, little or no attention has been paid to small ships which, in many cases, are old and not well maintained. Objective. The aim of the study was to evaluate the frequency and severity of Legionella contamination in ferries and cruise ships in order to adopt more specific control measures. Materials and method. A prevalence study was carried out on 10 ferries and 6 cruise ships docking or in transit across the port of Messina (Sicily, Italy). Water and air samples collected from many critical points were tested for qualitative and quantitative identification of Legionella. Results and conclusions. Legionella pneumophila sg 1 was isolated from the samples of shower and tap water in 7 (70%) of the 10 ferries examined, and in 3 (33%) of the 6 cruise ships examined, and L. pneumophila sg 2–14 in 8 (80%) and 1 (16.7%) of these ships, respectively. No Legionella contamination was found in whirlpool baths, air and ice samples. In conclusion, the data obtained confirm higher levels of Legionella contamination in local ferries and cruise ships, underlining the need to adopt corrective actions more specific for these smaller vessels.

    Introduction and objective. Several studies have reported therapy failures in patients with legionnaires’disease; however, antimicrobial resistance of clinical and environmental isolates of Legionella spp. has not yet been documented. Routine susceptibility testing of Legionella spp. is not recommended because of difficulties in determining standard minimal inhibitory concentration values. The purpose of this study was to analyze the antimicrobial susceptibility of Legionella pneumophila. strains isolated from a water supply system. Materials and method. Twenty-eight isolates of L. pneumophila (16 – L. pneumophila SG 1, 12 – L. pneumophila SG 2–14) obtained from water systems in public buildings in Poland were tested. Susceptibility testing was performed using the E-test method. The tested antibiotic were azithromycin, ciprofloxacin, and rifampicin. The medium used for the susceptibility testing was BCYE-, a special medium for Legionella cultivation. Results. Among the tested strains, L. pneumophila was the only one resistant to azithromycin. It was a strain of L. pneumophila SG 2–14 isolated from the water system in a sanitorium. All isolates were found to be sensitive to ciprofloxacin and rifampicin. However, the azithromycin-resistant strain exhibited higher ciprofloxacin and rifampicin MIC (1.5 μg/ml, and 0.19 μg/ml, respectively). The MIC50 for azithromycin, ciprofloxacin, and rifampicin were 0,032, 0,125, and 0,003 μg/ml, respectively. The MIC90 for azithromycin, ciprofloxacin, and rifampicin were 0,032, 0,125, and 0,003 μg/ml, respectively. Conclusions. Azithromycin resistance was found in one strain of L. pneumophila SG 2–14, but the resistance mechanism is unknown and needs further study. It is possible that therapeutic failures in Legionnaires’ disease may be associated with bacterial resistance which should be taken into account. The antibiotic sensitivity testing described in this study could be helpful in detecting the resistance of clinical L. pneumophila isolates. Ciprofloxacin and rifampicin have good in vitro activity against environmental L. pneumophila SG 1 and SG 2–14 in Poland.

    Opis:
    Background. This paper evaluated Legionella spp. water system contamination in the public facilities. Material and methods. Samples of warm water from the inner water supply system of 41 facilities in years 2009-2013 and 46 facilities in years 2014-2016 were collected for analyses. The facilities included school dormitories, boarding houses, school-education centers, halls of residence, nursery schools, kindergartens, and correctional institutions. Results. The results of research carried out on tap water in public facilities in 2014-2016 showed that in comparison to 2009-2013 the percentage of facilities from group I increased. In group III facilities a decreasing tendency was observed in comparison to research carried out in 2009-2013. Conclusions. The results indicate that it cannot be explicitly ascertained that the eradication methods of L. pneumophila from tap water systems of the analyzed facilities within the studied period were sufficient. Epidemiological analyses of this type should be successively and systematically continued and based of the largest possible number of facilities.
    Wprowadzenie. Celem pracy była ocena skażenia systemów wodnych w budynkach użyteczności publicznej przez bakterie Legionella spp. Materiał i metody. Materiałem były próbki wody ciepłej pobrane z wewnętrznej instalacji wodociągowej 41 obiektów w latach 2009-2013 oraz 46 obiektów w latach 2014-2016. Były to: bursy szkolne, internaty, ośrodki szkolno-wychowawcze, domy studenta, żłobki, przedszkola, zakłady karne. Wyniki. Wyniki badań sieci wody użytkowej obiektów użyteczności publicznej w latach 2014-2016 w porównaniu do lat 2009-2013, wykazały, że odsetek obiektów z grupy I wzrósł. W obiektach z grupy III stwierdzono tendencję spadkową w porównaniu do lat 2009-2013. Wnioski. Wyniki badań świadczą, że w analizowanym okresie nie można jednoznacznie stwierdzić czy stosowane metody eradykacji L. pneumophila z systemów wody użytkowej analizowanych obiektów są wystarczające. Tego typu analizy epidemiologiczne należałoby sukcesywnie i systematycznie kontynuować w oparciu o jak największą liczbę obiektów.

    Opis:
    Bakterie z rodzaju Legionella są rozpowszechnione w środowisku, zwłaszcza wilgotnym. Mają zdolność kolonizowania sieci wodociągowej i różnorodnych zbiorników wodnych sztucznych i naturalnych. Dotychczas wyodrębniono 42 gatunki i 64 grupy serologiczne, z których najczęściej przyczyną zachorowań jest L. pneumophila, serotyp 1. Człowiek zaraża się przez drogi oddechowe, wdychając zakażone pyły lub wodne aerozole. Do szczególnie narażonych na zakażenia należą osoby przebywające w pomieszczeniach o wzmożonej wilgotności powietrza. Legioneloza przebiega pod postacią ciężkiego zapalenia płuc o śmiertelności około 20% lub gorączki Pontiac o znacznie łagodniejszym przebiegu, bez przypadków śmiertelnych.
    The bacteria of genus Legionella are commonly present in the environment, especially in humid conditions. To date 42 species have been identifid of which Legionella pneumophila is the most frequent cause of diseases (1). Infections take place through the airways by inhalation of droplet aerosols from water or dust. The risk of infection is increased by high humidity of the air. Legionellosis may occur as a pneumonia with mortality of about 20%, or as a much milder flu-like illness called Pontiac fever.

    Opis:
    Legionnaire’s disease is a life threatening respiratory tract infection that is commonly associated with a stay in communal accommodations such as hotels, hostels, guesthouses and camping sites.In the European Alps and some other areas of the world mountain refuges and huts can sometimes accommodate over 100 guests in almost hotel like comfort. Such a “hut” may have cramped dormitories with multi-occupancy bunks and a basic water supply system possibly with hot water. Some will have showers. The water supply may be limited by the environment. As such these may pose a high risk for transmission of Legionellosis. In an environment of a hut which is more difficult to control than others. Unfortunately countries differ in their guidelines for the prevention of Legionnaire’s disease transmission within tourist accommodation. The aim of this paper is to propose a set of simple and pragmatic rules that can prevent the development of Legionella infections in mountain huts and other accommodations situated in the wilderness environment.

    Opis:
    The aim of the study was to assess the risk posed by Legionella bacteria in a public building in Krakow. An old building with internal installation risers of different ages, as well as draw-off points of different types, was selected for testing. Samples were collected during two campaigns. In one sample of the first series of tests, no bacteria were found. During the second series of tests, no Legionella bacilli were found in just one sample and in one sample only 4 colony-forming units were detected. At the remaining draw-off points (water taps), the bacteria count detected were greater than the maximum threshold allowed by legal regulations (admissible threshold for public utility buildings – 100 cfu/100 mL). No morphological differences were observed with respect to the occurrence of specific serogroups. In 14 samples, Legionella pneumophila serogroups 2–14 were found, while the Legionella pneumophila serogroup 1 was only found in one sample. The risk assessment was also carried out based on a semi-quantitative risk matrix approach and as a quantitative microbial risk assessment. The risk matrix approach was successfully implemented for the recognition of the potential risk associated with the Legionella occurrence in a water system. The calculated annual cumulative risk is high. The research shows that even if the weekly inhalation exposure dose (and therefore the calculated risk) is high, the number of Legionella pneumophila illness cases found can be equal to zero. This is probably due to the large uncertainty associated with QMRA determination. The size of the room in which the contaminated water is used also affects the possibility of infection.
