WHEN THE CHOICE IS MADE TO PROTECT IMMUNOCOMPROMISED PATIENTS WITH POINT OF USE FILTERS, DO NOT FORGET SOME CRITICAL POINTS.

WHEN THE CHOICE IS MADE TO PROTECT IMMUNOCOMPROMISED PATIENTS WITH POINT OF USE FILTERS, DO NOT FORGET SOME CRITICAL POINTS.

In a very interesting paper published by the University Hospital of Montpellier (Tracking the spread routes of opportunistic premise plumbing pathogens in a haematology unit with water points-of-use protected by antimicrobial filters. Baranovsky S. et al. Journal of Hospital Infection,2018,98,53-59) the confirmation of the necessity to not forget some critical points in the water safety plan is scientifically proven. The objective of this study was to assess the effectiveness of water filtration in daily practice and to track secondary non-filtered…

Environmentals Reservoirs of persisting Carbapenemase-Producing Bacteria.

Environmentals Reservoirs of persisting Carbapenemase-Producing Bacteria.

Reservoirs of antibiotic-resistant bacteria are of great importance for the risk of a « naive » new patient to be contaminated when hospitalized in the room of a previously colonized or infected patient by an extended- spectrum betalactamase-producing bacteria. This risk may be considered near to 2 for this naive new patient in comparison to the risk encountered when hospitalized in a room previously occupied by a non-infected patient. This is particularly hazardous in case of gram negative carbapenemase-producing bacteria (CPB) which…

WHY TO USE POINT-OF-USE FILTERS IN IMMUNE COMPROMISED UNITS

WHY TO USE POINT-OF-USE FILTERS IN IMMUNE COMPROMISED UNITS

Bone Marrow Transplant / Neonates Intensive Care Unit / Intensive Care Unit / Burn Unit Patients hospitalized in bone marrow transplantation, NICU and other high risk hospital units have zero immune system due to the treatments used for avoiding the reject of the bone marrow transplantation and other immune suppressing environment factors; thus the necessity to protect these patients from environmental contamination is accepted worldwide. For years, diverse ventilation systems and air treatment processes are dedicated to insure a specific air quality…

There is now a largely diffused information in the public related to the risk of waterborne contamination and infection since some mediatic outbreaks of gastroenteritidis, legionellosis and health-care associated infections. The request of a safe environnement, both in hospital settings and public receiving buildings is clearly expressed by the users who don’t hesitate to go in front of a…

MANAGING THE WATERBORNE RISK IN THE HEALTH SETTINGS.
THE FRENCH GUIDELINES 2005.

Introduction Since the 80’s some cases of waterborne Healthcare Associated infections (HAIs) were described, but this concern was really taken into consideration in France during the 90’s, in relation with the Mycobacterium xenopi outbreak in the « Clinique du Sport » in Paris from 1993 to 1999 (1). A first case of osteomyelitis after endoscopic nucleotomy was reported in june 1993, inducing investigations which evidenced 9 cases, all operated in this clinic under endoscopy from 1988 to 1993. The origin of this…

THE DIFFERENT FACTORS
OF BACTERIAL ATTACHMENT AND ADHESION ON SURFACES
Professor Philippe Hartemann

THE DIFFERENT FACTORS
OF BACTERIAL ATTACHMENT AND ADHESION ON SURFACES
Professor Philippe Hartemann

The attachment of bacteria and other microorganisms on surfaces is the result of some physicochemical links and interactions and their own metabolical characteristics. Then occurs a second phase, called adhesion, linked to those factors in interaction with others of biological nature. These two phases could be eventually followed by a third one, the colonization if cleaning and/or disinfection of the surface at this place are inefficient … or not performed. This leads to the formation of a biofilm. The attachment…

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…

Legionella longbeachae, legionnaires’ outbreak source

Legionella longbeachae, legionnaires’ outbreak source

In Europe, Legionella pneumophila is responsible for 95% of Legionnaires’ outbreaks. Among the remaining 5%, the causative agent is Legionella longbeachae.     This bacteria belongs to family Legionellaceae and was first isolated in 1980  in California (USA)  from a patient who had a pneumonia . Areas where it developed are still unknown. However the source of human infections are soils, and compost derived products such as bark and sawdust. In New-Zealand, a recent study had been about people hospitalized who had a pneumonia via Legionella longbeachae….

Legionella biofilms

Legionella biofilms

  A biolfilm is a multicellular community of microorganisms composed of bacteria, fungi, algea or protozoa which develop on a surface. Microorganisms synthetise a matrix which allow a protection and adhesion and each group performs specialized metabolic functions. Biofilms are usually found in high humid areas, on solid substrate submerged in or exposed to an aqueous solution. It can also form as floating mats on liquid surfaces. Biofilms protect microrganisms from worse conditions for their developement. In the cycle of life for…
