“…Therefore, the presence of all these bacterial varieties with resistant strains in treated water is a matter of concern in HD centers and should be taken seriously when assessing HD water quality by performing routine monthly disinfections with high-level disinfectants. Other solutions to improve the quality of HD water were recommended: disinfecting machines frequently by updating the disinfection protocol (Asserraji et al 2014;Verma 2015), biofilm analysis on tubing dialysis machines (Marion-Ferey et al 2003), improving nursing education on dialysis water (Chamney & James 2008), and conducting monthly quality assurance for risk analysis to the progress of water quality. The choice of piping materials is also essential.…”

The water treatment process is a vital factor for hemodialysis (HD) patients. This study aimed to assess the degree of contamination of HD water by bacteria at the HD center of Mohammedia, Morocco, in addition to evaluating the antimicrobial resistance of isolated bacteria. Fifty-four water samples were taken, the appropriate cultures were used to isolate the pathogenic bacteria, which were identified biochemically and molecularly by 16S RNA sequencing. Their susceptibility to antimicrobial drugs was determined by the disk diffusion method. Approximately 5.5% of water samples were above the norm. The isolated bacteria that colonized the HD systems were mostly Gram-negative bacilli, such as Stenotrophomonas maltophilia, Pseudomonas spp., and Burkholderia cepacian. Results of the antibiotics test showed remarkable resistance levels. Among Pseudomonas spp. and S. maltophilia, 10 strains were classified as multidrug-resistant (MDR), and 4 as extensively drug-resistant (XDR). The diversity of bacterial strains isolated in the water used for HD treatments, and their worrying resistance levels pose a significant risk to patients. For these reasons, an urgent need for periodic microbiological monitoring of water after each treatment step must be applied, and the treatment process should also be optimized.

“…In one study on the bacteriological quality of treated water and dialysis in hemodialysis unit of a tertiary care hospital in 2015, it showed that thirty-six samples of treated water and 394 samples of dialysate analyzed for bacteriological contamination. 4 out of 36 (11.1%) samples of treated water and 44 out of 394 dialysate samples (11.2%) showed unacceptable bacteriological growth [15]. Totaro et al 2017 in Italy, from nine-dialysis water plants at nephrology wards within the city examined for identify microbial and chemical hazards.…”

Background: A single 4-hour dialysis treatment can require up to 400 liters of water per week for dialysis patients compare that with healthy person who drinks less than 15 liters of water per week. Therefore, it is clearly important to know and monitor the chemical and microbiological purity of the dialysis water. Aims: Determine the physicochemical and bacteriological characteristics of water used by hemodialysis services Isolate and identify fungi present in water systems of hemodialysis units in Benghazi Medical center (BMC) in Benghazi, Libya. Methods: Analysis study carried out in hemodialysis unit in BMC collected samples from each places (A & B) sections. Results: Six samples that target to chemical analysis and 32 samples for microbiological test, Chemical parameters of study area A and B for drinking and dialysis water were within international standards, but there was a minute of Calcium elevation in area B that was 3.3mg/l. No contamination with bacteria observed in all samples in section (A), the counts of yeasts and filamentous fungi investigated in the tap water, in the treated water, and dialysis machine in section B and Penicillium spp was the most frequent fungi. Conclusions: Our study demonstrated that the tap and dialysis water success to meet the all-chemical and microbiological requirements in (A) area inside hospital of Benghazi center. In generally to prevent the risk of contaminants for hemodialysis patients need to a high water quality management program and development of water treatment system in hemodialysis centers.

“…The bacteria enter the bloodstream through the oral cavity or other gates e.g. through lines and dialysates of hemodialysis, migrate to different places and damage the endothelium [37]. They weaken the intima of vessels, proliferate, create their biological colony, and build the plaque.…”

The main cause of atherosclerosis is not completely understood. Besides the classical risk factors, food intolerance and its microbiota promote inflammation. IgG antibodies against antigens and microbial genomes have been detected in atherosclerotic lesions. It has been suggested that fruits despite their benefits in terms of nutrients and anti-oxidative properties may also act as "enemies" provoking diseases through immunity pathways. The current production of fruits involves the use of conservatives, insecticides, fungicides, herbicides, acaricides, surface disinfectants etc. hostile to human body. Banana contains microorganisms which may use our "ecosystem" to build colonial biofilms called plaques in order to survive. Their metabolites create acidic environment resulting in illnesses and even death. The primary outcome of this computerized search was that there is a direct and indirect association between banana intolerance and arteriosclerosis. There is limited information about fruit antigens and microbiota and their interactions with the host. Biofilms and immunity complexes could link banana with atherosclerosis. The banana contains nutrients good for us and for our intrinsic "habitants" and microflora which interacts and modulates the host microbiota. Plaques are reconstructed by living "microbes" fighting for home and food. Banana's antigenic load triggers the production of immunocomplexes which are deposited on the vascular walls and initiate atheroma formation. Extensive studies on the biology and "dietology" of diseases should be conducted to further clarify the "gaps" of this issue.
