Abstract
bjective: To study throat culture and antibiogram results in treatment of acute pharyngitis.
Methods: 105 patients with acute pharyngitis were included in this prospective study. From all of the patients throat culture and gram-stained smear were provided. Antibiogram was done in patients with posit throat culture.
Results: 63 patients of 105 patients (59%) have negative throat culture and gram stained smear from pharyngeal secretions. 20 patients (19%) have positive throat culture and gram - stained smear. 12 patients (12%) have positive throat culture and negative gram - stained smear. Therefore 32 patients (31%) of 105 patients have bacterial pharyngitis. Fever, pharyngeal and tonsillar purulent exudates and adenopathy in patients with positive throat (31%) was more common than patients with negative throat cultures (69%). The most common cause of bacterial pharyngitis was group betahemolytic streptococcus.
Conclusion: Antibiogram findings revealed that bacterial pharyngitis such as streptococcal, staphylococcal and pneumococcal were completely resistant to Penicillin, Amoxicillin and Ampicillin that are used routinely in out patient clinics, and on the other hand were sensitive to unusual antibiotics in treatment of acute bacterial pharyngitis. Including Doxycicline, Vancomycin and Erythromycin and they are better alternatives.
