In this study, it is proposed to investigate how much influence the conditions that have lived these buildings in the increase of the proliferation of bacteria and fungi inside. For this, samples of bacteria and fungi will be taken in three buildings affected in different ways by Hurricane Maria. The first building chosen will be the building of the Metropolitan University (UMET) which is without any electrical energy and therefore without central air conditioning. The second building to be selected is that of the University of Turabo (UT) that has had electrical energy selected by an electric generator, however, it does not have the central air conditioning. Finally, the building of the Universidad del Este (UNE) was chosen, with both the electric generator and the central air conditioning. The different conditions of these buildings will be taken into account as possible experimental variables, giving us the opportunity to compare bacterial and fungal growth in different conditions of humidity and temperature. We will be using TSA plates exposed for 24 hours and TSA contact plates to collect our samples. To these bacteria and fungi are the different types of biochemical tests to preliminarily identify what type of bacteria/fungi are found within these buildings. In conclusion, it resulted in the building that was previously ill seriously that of the UMET, due to the conditions in which the building was decided.
