What Is The Poptropica Hacking Device

Hotel prevent legionella

Temperatura di crescita

Legionella si moltiplica tra 25°C e 42°C con temperatura ottimale di 35°C

PH di crescita
The optimum pH for growth is slightly acidic (between 6.85 and 6.95), but is tolerated up to a pH of 5.5

Breathing
are aerobic bacteria, but their growth is favored by artificial turf in microaerobic (presence 2.5% CO2), especially in the first isolation

Natural Environment
Legionella bacteria are natural aquatic environment. Are in:

- Rivers
-
Lakes - Ponds
- Collections surface water of any kind
- Soil wet



Urban environment - water distribution
-conditioning systems and humidifiers (towers / cooling condensers Evaporative)
- decorative fountains, spas, hot tubs, steam baths and sauna areas used as irrigation systems, wastewater sanitation
- Pools and tanks with standing water
- Equipment for inhalation

mode of contamination

• Few entering the plant and microbial cells reproduce themselves (20-45 ° C)

ESSENTIAL ROLE OF WATER HOT

additional risk factors in tourism

Special tourist facilities
- distribution system of ' water complex (every room has a bathroom) and the long distances from the distribution site on the faucet
- short stays, variability in the use depending on the season:
- in high season water consumption concentrated at certain times of day and night (drop in water temp)
- in low season, low consumption or hotel closed with possible stagnation that facilitates the formation of biofilms
the quality of water supplied may vary and should be monitored more frequently
-poor knowledge of the problem

mode of infection

inhalation of aerosols contaminated
Aspiration of contaminated water to
Inhalation of dust particles derived therefrom for drying
not contracted by drinking contaminated water

Mode The legionella infection

contracts generally via respiratory inhalation of aerosols contaminated or microaspiration
The aerosol is formed by the droplets generated by splashing water or the impact of water droplets on the surface
Most are small (< 5 micron) più facilmente raggiungono le basse vie respiratorie
Intervention strategies



• Monitoring • Air conditioning • Water system
:
-run samples of water (hot and cold) at the level of priority (guest rooms) and centrally (boiler), then to ' entrance of the aqueduct, water softeners, kitchen and plans do not ancora occupati. All’inizio ogni 7 giorni, successivamente ogni 15 giorni, poi 1 volta al mese
