Change in the Pharyngeal Microbiologic Environment after a Tonsillectomy

By Lindsey Abramson

Introduction

Tonsillectomies, the surgical removal of the tonsils, are performed on individuals with chronic tonsillitis infections, recurrent strep throat, enlarged tonsils, and other issues such as cancerous cells (Brietzke and Andreoli, 2021). The goal of this radical procedure is the eradication of bacteria assuming antibiotics have been frequently used and failed / resistance was developed (Yildizoglu et al., 2015). Streptococcus pyogenes (also called group A streptococci, or GAS) is the causative agent bacterium of strep throat, one of the leading causes that push individuals towards an elective tonsillectomy (Slonczewski et al., 2024). Although viruses are also common, other problematic bacteria include: Staphylococcus aureus, Haemophilus influenzae, Streptococcus pneumoniae, Escherichia coli, and Pseudomonas aeruginosa (Yildizoglu et al., 2015).
