Chlorination of in potable water.

The present study examined the effects of chlorine (NaOCl) disinfection on in potable water. The adhesion of the bacteria on glass surfaces and the growth of the adherent cells were measured after treatment with chlorine (0, 0.25, 0.

Disruption of Pseudomonas aeruginosa Adherent Cells by NaCl and NaOCl in Drinking Water.

The aim of this study was to compare and explain the disruptive effect of sodium chloride and sodium hypochlorite on the adherent cells of P. aeruginosa on glass slides. To this end, the surface characteristics of glass slides and P.

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.

Adhesion Behavior of Strains on Glass: Role of Cell Surface Qualitative and Quantitative Hydrophobicity in Their Attachment Ability.

Microbial adhesion to surfaces is thought to involve physicochemical interactions between the substrate and microbial cells. Understanding the physicochemical aspects involved in the adhesion phenomenon, as a critical step in biofilm formation, is essential to finding ways to prevent their formation and control biocontamination risks. The aim of this study was to investigate the relation between the adhesion behavior of 12 strains isolated from food and their surface hydrophobicities using qualitative ( ) and quantitative (Δ ) approaches.

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.

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.
