Cryptosporidium

Cryptosporidium

Hydric pathogen microorganismes present in water can be divised in three parts : virus, bacteria and protozoa. Virus and bacteria grow in surface water and underground water, whereas protozoa grow mainly in surface water.   Cryptosporidium Cryptosporidium is a parasite protected by an outer shell that allows it to survive outside the body for long periods of time. This parasite can be spread in several ways but the most common is by water not treated. It is a leading cause of…

HAI, what is it ?

HAI, what is it ?

HAI’s (Healthcare Associated Infections) also called nosocomial infection are  infection thats are acquired in a hospital or other Healthcare facility .   CAUSE ? These infections develop after germ or bacterial contamination in a healthcare facility. Pathogen agents spread easily trought the skin, so people with a weakened immune system are fragile. The contamination could be from air, water, materials, or food. HAI could appear 30 days after a chirurgical operation or one year after a stranger material in the body…

France, new application to prevent legionella risk

France, new application to prevent legionella risk

  A french start-up has developed an application which permit to detect conditions that could be appropriate for a legionella development. Indeed, this application provide link to water system to detect temperatures too cold or too hot, optimal conditions in which legionella can develop. Clinical settings could have all day an alert on phone or computer about temperatures in water systems. An innovation which could provide a prevention from legionella risk and lead to a protection for residents or patients….

DNA testing can rapidly solve Legionella outbreaks

DNA testing can rapidly solve Legionella outbreaks

    Legionnaires’ disease is a potentially-fatal bacterial lung infection caused by legionella contamination. An estimated 8,000 to 18,000 cases a year in the United States require hospitalization. To detect potential legionella risk in an environment suspected, water samples are studied. Then bacterial cutlure show the potential presence of legionella. This analysis take few days before detect the pathogen bacteria and develop measure of prevention and control.   New approach with DNA ? “polymerase chain reaction (PCR)” American scientifics studied…

What are pseudomonas ?

What are pseudomonas ?

Pseudomonas are bacteria rod-shaped, aerobic which can reach 2 or 4 micrometers in size. They have one or more flagellum, providing mobility . They secrete green-blue (pyocynine), yellow-green (pyorubrine) or fluorescent pigments. Pseudomonas can grow on soil, water, plants and also humans. These bacteria have a large tolerance for temparature for their growing. They have an optimal temperature range for 30 et 35 °C , but they can also grow between 4°C and 42 °C slowing down their metabolism.   The most…

Stagnant water, potential area of bacteria contamination ?

Stagnant water, potential area of bacteria contamination ?

  You came back from holidays ? You want to drink water ? Be careful before using your faucet or taking a shower ! It is notice to run the tap for few moments before use water cold or hot  Why ? Studies showed that bacterial concentrations are highest in the first 100 milliliters of tap flow when water has stagned in pipes during few days. But that bacteria are not a risk for health. Scientifics worked on tap water in…
