Análise de coliformes totais e termotolerantes em água de bebedouros da Universidade Federal da Grande Dourados, Dourados, MS

Abstract

Contaminated drinking water poses a great risk to human health, requiring sanitation and monitoring, especially from a microbiological point of view. One of the parameters that define water quality is the evaluation of the presence or absence of the Coliform group, with the bacteria present in this group being the main cause of illnesses such as fever and diarrhea. Therefore, an analysis of the microbiological quality of four drinking fountains located at the Federal University of Grande Dourados, located on the Dourados/Itahum highway km 12. The method used was the most probable number (MPN) of total and thermotolerant coliforms by the tube technique multiples. Two samples were collected twice in different weeks from each drinker. The results obtained were absence of coliforms in tubes inoculated with Lauryl Sulfate Tryptose Broth (LST). This study concluded that it is of great importance to constantly monitor the water we consume, in accordance with the standards established by the Ministry of Health and WHO.
