ABSTRACT
Bacteriological and immunological study was done on 150 patients with severe periodontitis at the period from
1- 10-2010 to 1-6-2011in (College of Dentistry). the number of samples gave positive results for growth of
Porphyromonas gingivalis on blood agar were 35 sample ( 23.3%) while 115 samples (76.7%) gave appositive growth for
others bacteria like Streptococcus mutans .The results of immunological study on serum of patients gave positive culture of
P. gingivalis showed increasing in all immunological testing parameters including concentration of immunoglobulin s
such as ( IgM, IgG, IgA) , complement (C3&C4) , total protein comparing with healthy individual (20 person) whom
didn’t have periodontitis and gave a normal results to all tested parameters .
KEYWORDS: Porphyromonas gingivalis, Streptococcus mutans, IgM, IgG, IgA
