Detection Antibiotic susceptibility and some virulence factors for bacterial isolated from Pharyngitis patients

Abstract

The third most frequent primary complaint seen in outpatient medical facilities is pharyngitis. The most frequent causes of pharyngitis are usually infectious. This infection may lead to abnormally big tonsils and pharynx, which make it difficult to breathe and swallow. The purpose of this study is to evaluate the effectiveness of pharyngeal swabs for detecting some virulence in patients with pharyngitis, antibiotic susceptibility, and the most prevalent bacterial species that may be isolated from smear samples. In total, 115 throat swab samples were taken from selected patients in the pharyngitis department at Balad hospital. The results show 50 samples show positive growth on the media used, the number of Gram-positive samples are 42(84.0%) while number of Gram-negative samples are 8(16.0%). number of females is 15(30%), and the number of males is 35(70%), with ages ranging 1-69years. After that, samples were sent for culture, sensitivity, and detection of some virulence factors. The results showed that S.aureus 28(56%) , S.pyogenes 12(24%), S.epidermidis 2(4%), K.Pneumonia 2(4%), E.coli 3(6%), P.aeruginosa 3(6%). The sensitivity of the bacterial isolates under study was tested to 11 antibiotics. This study demonstrated that all isolates of S.aureus were sensitive to Imipenem, Azithromycin, Chloramphenicol, Gentamycin, and Amikacin, however resistance to Penicillin, Amoxicillin/Clavulanic acid, Ampicillin, Cefotaxime, Amoxicillin, and Tetracycline. S.pyogenes were sensitive to Imipenem, Tetracycline, Amoxicillin, Amoxicillin/clavulanic acid...
