Cyanotoxins are toxic substances produced by cyanobacteria, or blue-green algae, which can proliferate in water bodies under conditions like high nutrient levels and warm temperatures. There are over 1,118 different cyanotoxins identified globally in freshwater environments across 66 countries, illustrating the widespread nature of this ...
These diseases can affect individuals coming into contact with contaminated water sources ...
These, along with antibiotic resistant bacteria, get into municipal and hospital wastewaters, and may be spread into water sources by inefficient disinfection. Antimicrobial photodynamic treatment (aPDT) may be an alternative to tackle the issue of antimicrobial resistance spread. ...
Effective hand hygiene reduces the risk of meat contamination and the transmission of foodborne disease Clean hands are essential to health and effective handwashing is one of the simplest ways to prevent the spread of germs. Hand hygiene is particularly important in minimizing food safety risks along food animal chains, as there are many diseases that can be transmitted to humans from polluted ...
Maintaining sterile storage conditions is necessary to protect medical instruments, drugs, surgical implants, and other equipment from contaminants. ARON guidelines on sterilization are straightforward: temperatures should not exceed 72°F (22°C) to 78°F (26°C), relative humidity should not exceed 60%, and airflow should be positive pressure with at least four total air changes per ...
This “shipping effect” was observed with samples tested with lab culture and lab qPCR. (9) Weekly testing: The benefits of qPCR Genomadix’s qPCR test quantifies the amount of live Legionella in a water source in 45-minutes so you’re able to detect Legionella contamination in real-time. ...
There are two factors that can cause this problem: Stagnant water: Stagnation can occur in hot and cold water systems, irrigation systems, cooling systems, and cold water storage tanks. This can increase the growth of biofilms and free-floating bacteria, including pathogenic bacteria such as Legionella. Low water use: fewer ...
Pharmaceuticals and personal care products (PPCPs) in swimming pool water are hypothesized to originate from fill water and anthropogenic sources like urine, sweat, swimwear and body surfaces. ...
A literature search was conducted in order to review: (1) methods used for investigating the effects of public drinking water on GI; (2) evidence of possible dose–response relationship between sporadic GI and drinking water consumption; and (3) association between sporadic GI and factors affecting drinking water quality. ...
The purpose of this study was to investigate the susceptibility of waterborne strains of Legionella to eight antimicrobials commonly used in legionellosis therapy. The minimum inhibitory concentrations (MICs) of 66 environmental Legionella strains, isolated from fountains and cooling towers of public facilities (hotels, schools, and shopping malls) in Macau and Guangzhou, were tested using ...
Water is the main stimulus for the development of microorganisms, and its flow has an important role in the spreading of contaminants. In hospitals, the water distribution system requires special attention since it can be a source of pathogens, including those in the form of biofilms often correlated with resistance of microorganisms to ...
In addition to the BSF, this study evaluated household education level, socioeconomic status, water source and handling, and sanitation as factors impacting the occurrence of diarrhea for households in the village of Enseado do Aritapera in Para, Brazil. Of the 18 correlations examined, 16 were negatively correlated, and the strongest correlation was between the ...
Arsenic, a natural element of ecological relevance, is found in natural water sources throughout Argentina in concentrations between 0.01 and 15 mg/L. The autochthonous toad Rhinella arenarum was selected to study the acute toxicity of As and the biochemical responses elicited by the exposure to As in water during its embryonic development. ...
We assessed variation in AGI dynamics in general, and disaggregated by hydroclimatic regime and drinking water source. We used several different visual and statistical techniques to describe and characterize seasonal and annual patterns in AGI incidence over time. Our results consistently illustrate marked seasonal patterns; seasonality remains when the dataset ...
Surface water samples used for irrigation or domestic purposes, and water samples from the outflow of wastewater plants were collected from six provinces. ...
BioLargo has developed unique iodine solutions aimed to source and deliver “free-iodine” on demand. The company’s CupriDyne® solution works by combining minerals with water from any source to deliver “free-iodine” in controlled dosages, in order to balance efficacy of disinfectant or odor control performance with ...
An estimated 1.1 billion persons worldwide lack access to an improved water source. Hundreds of millions more drink contaminated water from improved sources because of unsafe water treatment and distribution systems and unsafe water ...
Hepatitis E virus (HEV) is a common cause of water-borne acute hepatitis in areas with poor sanitation. In 2004 an outbreak of HEV infection affected around 2,000 people in Eastern Chad (Dar Sila). ...
The purpose of this study was to investigate the occurrence of antibiotic resistance genes (ARGs) in water used for irrigation in the Werribee River Basin, Australia, including river water and reclaimed effluent water (reclaimed water). ...
