Environmental surveillance of Legionella pneumophila in hot water systems of hotels in Morocco.

Objective: Environmental monitoring of Legionella in hot water systems of hotels in Morocco was performed during the period from January 2016 to April 2018. A total of 149 water samples from 118 different hotels were analyzed.

Methods: A total of 149 water samples from 118 different hotels were analyzed.

Role of biofilms in the survival of to sodium chloride treatment.

Background And Objectives: Legionnaires' disease continues to be a public health concern. Colonized water distribution systems are often implicated in transmission, despite the use of various disinfection strategies, the bacterium is capable to persist and survive in water systems. The aim of this study was to investigate the persistence of to sodium chloride over time at different temperatures and analysing the role of biofilms in the survival of this bacteria.

The theoretical adhesion of Pseudomonas aeruginosa and Escherichia coli on some plumbing materials in presence of distilled water or tap water.

The main aim of this work was to determine the most appropriate materials for the installation of a water system according to the characteristics of the water that passes through it. To this end, we conducted an investigation of the effect of two types of water (SDW: sterile distilled water and STW: sterile tap water) on the properties of bacterial surfaces and the theoretical adhesion of two bacteria (Pseudomonas aeruginosa and Escherichia coli) on six plumbing materials. Contact angle measurements were used to determine the surface energies of bacteria and materials.

Antimicrobial Susceptibility Patterns of spp. Strains Isolated from Water Systems in Morocco.

is a waterborne pathogen that causes a severe form of pneumonia called Legionnaires' diseases, which is normally acquired by inhalation of aerosols containing originating from natural and man-made water systems. The aim of this study was to describe the level of antimicrobial susceptibility of environmental spp. strains to preferred and recommended therapeutic agents to treat disease.

Adhesion of Legionella pneumophila on glass and plumbing materials commonly used in domestic water systems.

We aimed to investigate the adhesion of Legionella pneumophila serogroup1 and L. pneumophila serogroup2-15 on glass, galvanized steel, stainless steel, copper, Polyvinyl chloride(PVC), Cross-linked polyethylene(PEX-c) and Polypropylene Random Copolymer(PPR). The surface physicochemical properties of both bacterial cells and materials were estimated through contact angle measurements.
