Pathogenicity of Streptococcus pyogense associated among tonsillitis patients and Tonsillectomy (Published)

Two hundred    patients with tonsillectomy (TS)   in Basrah, 102(51% ) males  and 98(49% ) Females, with male: females ratio (1.04:1) and 50 individual without tonsillitis  problems as control group were included in this study, which was done during the period of April,2015 to Jun, 2017. This Include collection of throat  swab samples, culturing of samples, identification of causative agents species and antibiotic sensitivity. Gram’s positive  bacteria were the commonest  microorganisms .the  comments’ causative   agents was    Streptococcus pyogense 30 isolates (15%) followed by Staph.aureus   was  28 isolates (14%)  isolated   from  (200) chronic  tonsillitis   patients  before  and  after  tonsillectomy,while  the  most   normal  flora   was Streptococcus.(α-heamolytic)   45 isolates (90%),,followed by Staphylococcus epidermidis   40(80%)  from  (50 ) health  persons . Most  isolated  of  Streptococcus pyogense were  high  sensitive  to antibiotic  such  as   Clindamycin, Rifampin,     and Azithromycin . while  moderate  sensitive  to    Penicillin-G  Cefotaxime, Cefetriaxone, trimethoprim , and   resistant  to  Augmentine, ampicillin, Cloxacillin,  in  this  study  most  commo Streptococcus pyogense isolated  associated   with  pyrogenic  toxin   SPeB (76%),flowed  by   SPeC (60%)and  SPeA (26%) .
