Colonização microbiana em superfícies de banheiros de shoppings centers

Abstract

All environments are subject to microbiological contamination, as microorganisms are present on various surfaces, and there is an interaction that, under certain conditions, associated with the host's conditions, can assume a pathogenic pattern. And this contamination can occur through direct and indirect interpersonal contact, surfaces and inanimate objects in public restrooms. Therefore, understanding the dynamics of proper use, especially in shopping mall restrooms, as they have a high demand for people circulating, requires attention to surfaces that have a high probability of cross-contamination, such as toilets, latches, faucets and sinks. Therefore, the objective of this study was to quantify, isolate, and identify colonies, also evaluating their sensitivity or resistance profile in relation to various antibiotics. The collections were performed on different contact surfaces of the women's and men's restrooms of two shopping centers. The collection was carried out in March 2025, by rubbing sterile swabs soaked in saline solution, totaling 48 surfaces. And from these surfaces there was bacterial growth on all plates with bacterial predominance of gram-positive cocci, with 62%, followed by gram-positive bacilli, with 25% and finally gram-negative bacilli, with 13%, corresponding to 37 isolates identified and distributed in 8 species, which are: coagulase-negative Staphylococcus, Bacillus sp., Pseudomonas aeruginosa, Staphylococcus aureus, Acinetobacter baumannii, Burkholderia cepacia, Enterobacter cloacae and Chryseomonas luteola.
