Resumo: | The objective of the work was to study the microbiota of the conjunctival secretion of health professionals. Samples were collected from the clinically normal eyes of 40 health professionals in four different sectors, Proctology, General Intensive Care Unit (ICU), Male Ward, and Oncology of Hospital das Clínicas Dr. Augusto Leite, Aracaju, SE, Brazil. Ten professionals from each sector were selected. The samples were inoculated into various culture media: blood agar, Chapman agar, EMB medium (Teague), and Sabouraud dextrose agar with chloramphenicol. The bacteria most frequently isolated from all the sectors were Staphylococcus epidermidis (45.0%) and Bacillus sp (29.0%). The least frequent bacteria were Proteus sp (6.1%), Staphylococcus aureus (4.1%), Enterobacter sp (4.1%), Alcaligenes sp (4.1%), Citrobacter sp (2.1%), Moraxella sp (2.1%), and Proteus mirabilis (2.1%). Fungi were not isolated. These results confirm the continuous contamination of the conjunctival sac of these professionals by the external environment, while at the same time confirming that the mechanisms of local defence continue to be intact, preventing the fixation of invading microorganisms.
