Abstract:

A radio-frequency plasma system (RF) was used to investigate the removal of microorganisms from water.Plasma generated by RF radiation can produce active compounds (H•, •OH, H2O2, O3, etc.) that have a highoxidation potential and can kill microorganisms present in water (fecal coliforms and total coliforms). Thefrequency of the plasma system was set to 3.0, 3.3 and 3.7 MHz and applied to river water for 60 minutes. Theresults show that in all runs, the pH of the water produced was in the range from 7.4 to 7.9. The removalefficiencies of fecal coliforms achieved were between 83.75 and 95% and w

Abstract:

BACKGROUND: Nepal is one of the least developed countries and in most of the areas the water supplied directly from natural water sources (like streams, rivers etc.) is used for drinking purpose, without any prior treatment. So every year there are many water related outbreaks mainly in rainy season. Very little data is available about the bacteriological quality of the water from drinking water sources, in the country. This report presents a scenario of the bacteriological quality of the water from drinking water sources and reservoirs, supplying Dharan municipality of Nepal.METHODS: Bacterio

Abstract:

The coliform bacteria group consists of several genera of bacteria belonging to the family enterobacteriaceae. These are harmless bacteria, mostly live in soil, water, and digestive system of animals. Fecal coliform bacteria, which belongs to this group, are present in large numbers in feces and intestinal tract of human beings and other warmblooded animals which can enter into water bodies from human and animal waste. Swimming in water having high levels of Fecal coliform bacteria increases the chance of developing illness (fever, nausea or stomach cramps) from pathogens entering the body thr

Abstract:

Two main channels have been identified to be responsible for microbiological contamination of raw milk and milk products. Firstly, contamination has occurred due to udder infection from the cow or the blood which harbours most bacteria that come in contact with the raw milk. Secondly, via external factors (may include faeces, skin, contaminated water, environment etc.) which are associated with the operation of milking. There is direct contact with the milk and/or surfaces before, during or after the milking, posing public health risk and economic decline. The aim of this study was to examine

It is known that the majority of bacteria defined as fecal coliform in the coliform group are Escherichia coli. The presence of E. coli or fecal coliform bacteria in any sample is an indication that the necessary hygienic measures are not taken during production, storage, and sale. That means the sample is directly or indirectly contaminated with faeces, and/or other intestinal pathogens may also exist. In this study, raw milk, freshly
