BACTERIAL IDENTIFICATION AND ANTIBIOTIC SUSCEPTIBILITY PATTERNS OF STAPHYLOCCOCUS AUREUS ISOLATES FROM PATIENTS UNDERGOING TONSILLECTOMY IN KUTCH, GUJRAT, INDIA

This study aims to identify the bacteriology of both tonsillar swabs and biopsies specimens among children and adult patients diagnosed with CT and RT (infected tonsils). In addition to obstructive sleep apnea (OSA) and tonsillar hypertrophy (TH) (non-infected tonsils) all undergoing elective tonsillectomy and to characterize the antibiotic susceptibility patterns of the most common isolate. A total number of 138 surgically removed palatine tonsils were collected from 72 patients. Six types of antibiotics were selected to test the susceptibility of Staphylococcus aureus isolates which are methicillin, gentamicin, erythromycin, cotrimoxazole, clindamycin and fusidic acid. The most common isolate was S. aureus (190 isolatre) followed by Haemophilus influenza (83), Streptococcus Group B (61), Haemophilus parainfluenza (33), Klebsiella pneumoniae (32), Streptococcus Group G (29), Streptococcus Group F (14), Streptococcus Group C (12), Pseudomonas aeruginosae (10) and Streptococcus Group A (9) and Streptococcus Group A (9). There was a 30.5% difference in the type of bacterial isolates between tonsillar swab and biopsies. The high prevalence of S. aureus in patients with both infected and non-infected tonsils suggests that this bacterium might not be the aetiological agent of chronic and recurrent tonsillitis. The increased rate of resistance 10.6% to fusidic acid among methicillinsusceptible S. aureus (MSSA) isolates makes this antibiotic a less potential drug of choice for patients with chronic and recurrent tonsillitis.
Key words: Antibiotic susceptibility, Staphylococcus aureus, swab, tonsillectomy.
