Abstract

Background and Aims: The aim of this study was to evaluate the bacterial sensitivity of the ‎tonsillar core and to evaluate the antibiotic susceptibility to determine the currently selected ‎antibiotic and to treat chronic tonsillitis and to reduce the need for surgery and to correct the ‎resistance caused by inappropriate use of antibiotics.‎ Methods: This prospective study included the analysis of 96 patients with chronic and ‎recurrent tonsillitis who underwent tonsillectomy in Imam Khomeini Hospital of Ahvaz. In this ‎study, 96 patients were enrolled. The average age was about ten years. 41 patients were female ‎‎(42%) and 45 (58%) were male. The youngest age was 5 years and the maximum age was 25 ‎years. The cause of tonsillectomy (35%) was obstructive and 61 cases (64%) were infectious.‎ Results: In this study, about 11% have negative culture and, fortunately, about 89% have ‎positive culture reported. The positive Gram-positive strains cultured were Staphylococcus ‎aureus and Staphylococcus coagulase. The negative Germ-free cultivars Includes Pseudomonas ‎and klebsiella pneumonia and klebsiella oxytoca. No sample of staphylococcus epidermidis was ‎reported. The most isolated were Staphylococcus aureus with about 50%. Other isolates ‎included Pseudomonas and Klebsiella and Staphylococcus coli. The most isolated isolate was ‎Staphylococcus aureus. ‎Conclusion:  Our study suggests that the type of isolates and antibiotic resistance are changing ‎and requires a new look at the appropriate antibiotic selection and requires more studies. In ‎most isolates, antibiotic resistance was high, which is probably due to misuse of antibiotic ‎regimens in recent years. On the other hand, there was resistance to very new antibiotics, and if ‎this trend continues falsely, it will lead to the fate of the resistance of antibiotics‎‎‎‎.
