Microbiological characterization of the concrete laboratory and the first-floor bathroom of the Santo Tomás University, Tunja branch, campus headquarters

Abstract

This work was carried out in order to report the quantity and types of microorganisms found in two areas of the Santo Tomas University campus, Tunja section (first floor bathroom and concrete laboratory), which have a large influx of students, teachers and administrative staff. Sampling was carried out for two weeks. To perform a comparative analysis of the data obtained in a practical way from the CFU and temperature, two exercises were proposed in which three mathematical models were implemented: Newton's Law of Cooling or Heating, Population Growth and Logistic Growth, the Excel program was used in which a macro was created in Visual Basic where the mathematical models were implemented. 37 CFU were obtained in the concrete laboratory and 22 CFU in the bathroom area in the sampling of the first week, in the second week 59 CFU were found in the concrete laboratory and 49 CFU in the bathroom. It was concluded that the laboratory, being a place where large quantities of materials and elements are found, such as different types of soils for the production of concrete in the civil engineering field, as well as the large influx of people and tools which are used to carry out topographic surveys or for the proper performance of different academic practices, generate and bring with them microorganisms, which are able to spread very easily.
