“…This Legionella species was cultured from the articular tissue of a woman aged 80 years. The majority of extrapulmonary infections are associated with direct inoculation of the microorganism into a wound site during bathing or upon contact with contaminated water (26). In general, extrapulmonary Legionella infections are more prevalent in immunocompromised patients and patients with rheumatoid arthritis (27).…”

OBJECTIVE: To determine the current presence of Legionella spp. in the output water of dental unit waterlines (DUWLs) and examine its mitigation by disinfection at the Institute of Dentistry and Oral Sciences, Faculty of Medicine and Dentistry, Palacky University Olomouc and University Hospital Olomouc. MATERIAL AND METHODS: The fi rst stage of our survey involved collecting samples of DUWL output water from 50 dental chair units (DCUs), and 2 samples of the incoming potable water. In October 2015, a one-time disinfection (1 % Stabimed) of DUWLs was conducted. This was followed by collecting 10 control samples (survey stage 2). RESULTS: From the total of 50 samples (survey stage 1), 18 samples (36.0 %) tested positive for Legionella spp. Following the disinfection, nine of the ten samples no longer showed any presence of Legionella. CONCLUSION: Based on culture results, the one-time disinfection (1 % Stabimed) was effective. We are unable to comment on the duration of positive effect of disinfection on the occurrence of Legionella spp. in the outlet water. It was a one-time survey (Tab. 2, Ref. 32).

“…De forma global, hasta el 60-90% de los receptores de TOS sufren alguna infección por CMV tras el trasplante 34 . Sin embargo, el aislamiento de CMV en una muestra clínica (incluida la sangre) no siempre es sinónimo de enfermedad por este virus, y por lo tanto, no siempre es necesario instaurar un tratamiento especí-fico.…”

Organ transplantation has become one of the most important areas of medical research and, at present, is still the only therapeutical tool for several diseases. However, there are a number of factors related to transplantation, like immunosuppression and prolonged neutropenia that affect the incidence of infection. These infections are somehow peculiar to trasplant recipients. In fact, there are infectious diseases that only occur in immunodepression situations and, moreover, clinical expression of these infectious diseases can be quite different from that in immunocompetent patients. Besides these aspects, some infections, due to the high prevalence described, must be considered for prevention strategies because they continue to be a principal cause of morbidity and mortality, either due to direct effects or to their implication in the pathogenesis of rejection. These strategies commence before trasplantation by active immunization through vaccine administration to the patient and to people in the milieu and continue after trasplantation with prophylaxis or pre-emptive therapy. The importance of infectious diseases in the evolution and prognosis of trasplant recipients gives a special meaning to the understanding of associated infections, their clinical expression and ways of prevention and treatment.

“…A Medline search from 1966 to 2001 found 43 such outbreaks, of which 69% (29) could be linked by epidemiological and molecular evidence to biofilms (a community of microorganisms growing as a slimy layer on surfaces immersed in a liquid) in water storage tanks, tap water, and water from showers. [229][230][231][232] Pathogens identified in waterborne nosocomial infections include: Legionella spp., P. aeruginosa, 233,234 Stenotrophomonas maltophilia, 235 Mycobacterium avium, 236 M. fortuitum, 237 M. chelonae, 238 Fusarium spp., 239 and A. fumigatus. 240 Even if hand hygiene practices are in place, a plausible route for transmitting these organisms from water to patient could be through HCWs' hands if contaminated water is used to wash them.…”
