• Abstract:

  Introduction: The microbiota refers to the population of microorganisms that inhabit the skin and mucous membranes of healthy people and can be classified as resident or transient. In terms of quantity and quality, it can be said that the microbiota is not uniform, as each region has a microbiota with its own characteristics. Aim: To identify the aerobic oropharyngeal microbiota of patients hospitalized for elective head and neck surgery at the time of hospital admission and to see if there were any changes in this microbiota 48 hours after admission. Method: 99 samples of secretion from the posterior wall of the oropharynx were collected from hospitalized patients using a sterile bacteriological swab or loop. The samples were collected on admission and 48 hours after hospitalization and submitted to microbiological analysis. Results: 64.64% of the patients showed a change in the aerobic microbiota of the oropharynx after 48 hours of hospitalization. Conclusion: Candida albicans, Candida tropicalis, Enterobacter aerogenes, Escherichia coli, Klebsiela oxytoca, Klebsiella pneumoniae, Micrococcus spp, Proteus mirabilis, Pseudomonas aeruginosa, Serratia marcescens, Staphylococcus aureus, Staphylococcus coagulase negative and Streptococcus viridans were identified in the oropharyngeal microbiota of the research participants and 64.64% of the individuals studied showed changes in their microbiota.
