The public should be warned that the water served by the Westerly Public Water System should be boiled before drinking. It is suggested by the RI Department of Health that all water be boiled for at least one minute, and allowed to cool before drinking. Studies indicate that boiling water kills bacteria and other organisms contained therein. If boiling the water is not available, bottled water can also be used instead. It is recommended that boiled or bottled water must be used for drinking, making ice, brushing teeth, washing dishes, food preparation, bathing of infants and others, until further notice. Studies confirmed the presence of E. coli bacteria in the water supply of Westerly Rhode Island.
The article stressed that E. coli in these waters indicate that it is contaminated with human or animal wastes. These bacteria are known to cause diseases such as diarrhea, nausea, vomiting, headaches and other symptoms. E. coli should be taken seriously especially for people with weakened immune system. Likewise, these bacteria may pose a risk for infants, toddlers, young children and even adults whose compromised immune system is severely compromised. Read the rest of this entry »
Fecal-Indicator Bacteria in Surface Waters of the Santee River Basin and Coastal Drainages, North and South Carolina, 1995-98
This article examines the possible effects of fecal indicator bacteria found in rivers and streams. Possible pathogenic or microorganisms that are able to cause disease include cholera, dysentery, Hepatitis A and typhoid fever. Symptoms of these water borne diseases consist of severe vomiting, diarrhea, fever and also eye, ear, nose and throat infections, to name a few.
In our water systems, pathogenic bacteria are not routinely tested. Coliform bacteria such as Escherichia coli or E. coli, and enterococci are commonly tested and are used as indicators of sanitary water supply. These are present in higher quantities in fecal matter and are easily detected. Read the rest of this entry »
It is a common knowledge that bacteria is abundant everywhere. They can be found in land and in water. The United States Geological Survey released a report on fecal bacteria found in rivers and streams of the Wind River, Big Horn River, and Goose Creek Basins in Wyoming.
Studies show that it is not unusual to find these types of bacteria in rivers and streams where human beings, wildlife, and domestic animals are nearby. Findings of the study conducted with the aid of the microscope revealed that bacteria concentrations in the streams were related to the use of the land. Generally, the concentrations were lower in streams adjacent to forested and rangeland areas as compared to streams adjacent to agricultural and urban areas. The purpose of the study was to measure both Escherichia coli and E. coli, which is a bacterium that is found in the intestines of warm-blooded animals as well as fecal-coli form bacteria, a class of bacteria found in the intestines of warm-blooded animals and other sources. These bacteria can be observed closely under the microscope. The presence of either of these in a stream gives an indication that the water may have been contaminated by fecal material from warm-blooded animals. Under the microscope, these microorganisms can be examined extensively.
Concentrations of E. coli and fecal-coli form bacteria were found to be closely related. The result is significant especially for the State of Wyoming which is switching from a fecal-coli form standard to an E. coli standard in determining whether their water is safe for recreational use. Some scientists believe that E. coli can be better correlated with illness which is associated with swimming since it provides more direct proof of fecal contamination in streams. The results from the study will aid regulators interpret the newly acquired E. coli data in relation to historically collected fecal-coli form data, thereby easing the shift from the old standard to the new one.

The article dealt with the behaviors of bacteria. Discovery may perhaps show the way to novel nano-devices and comprehension of the disease. The Escherichia coli cells utilize elongated, slender composition known as flagella to push or to propel them.
Researchers gave details of novel discovery regarding how particular bacteria propel themselves from one place to another. Knowledge regarding the micro-movement of bacteria will profit the researchers, engineers and scientists that are involved in developing nano-scale power-driven tools that someday will thrust fluids and transmit molecules in the absence of force or electrical charges.
The discovery may possibly aid in clarifying how diseases-causing bacteria or pathogens navigate the human body when initiating an illness.
