Bacteriological study of in Kirkuk City

Tonsillitis is one of the most widespread diseases; for the period from November 1/11/2023 to January 18/1/2024, 36 smear samples were taken from persons with tonsillitis of both sexes, within the age range of (4-60) year. They had performed their source diagnostic tests on basis of cultural, microscopic, and biochemical characteristics of 24 different aerobic bacterial isolates from 36 samples of persons suffering from tonsillitis. According to the findings made by this study, there are high chances of contracting tonsillitis infections from Gram-positive bacteria than from the Gram-negative bacteria. Gram-positive bacterial isolates in this study was found to be (21) isolates, 87.5% while Gram-negative bacteria was found to be (3) isolates, 12.5%. A sensitivity test for some of the antibiotics and reagents was carried out and the result of the test for Staph. aureus isolates showed high resistance to the specific antibiotics Azithromycin, Cloxacillin, which were 93%, 80% respectively while 73% for each of Ceftazidime and Amoxicillin. The findings also confirmed that the Streptococcus spp isolates had no resistance to the Amoxicillin, which was 100% resistant and Cloxacillin which was 83%, while moderate sensitivity was recorded to the Azithromycin, which was 83% sensitive and moderate resistance to the Ceftazidime, which was 33% resistant. Concerning Klebsiella spp isolates, they were all resistant to Azithromycin, moderates to Cloxacillin and Amoxicillin at 67% each. Also, the Klebsiella spp isolates proved highly sensitive to Ceftazidime at a 100% level of sensitivity.
