Although more than 30% of the Egyptian females carry SGB in the vagina ,E.coli and Enterobacteriaceae species are the leading cause of neonatal infections . SGB strains are found now to be an important invasive pathogen in the Egyptian adults between community acquired patients .

A total of 99 SGBs were isolated from 51 male and 48 female patients , serotypes 1a, 11 ,111, and V were the predominant types accounting for 83% of the isolates ,of which 25% were type V . The 17% rest were belonging to types 1b, 1V, V1,V11 and V111.  31 SGB serotypes 1a, 1b, 11, 111 and V were isolated from urinary tract infection patients  . 25 SGB serotypes 1b, 11,V and V11 were isolated from male patients suffering from prostatitis and urethritis . 12 SGB serotypes 11,111, V and V1 were isolated from male patients with diabetic foot infection and 10 SGB serotypes 1a,11,111 ,V and V1 from the female patients ,of which 80% from both patients were types  11 and V. 

Antibiotic susceptibility test  for SGB was performed by disc diffusion method and the zones of inhibition were measured according to the CLSI regulations . All strains were sensitive to penicillin , ampicillin , vancomycin and linezolid . 4 strains were resistant to macrolides only and 10 were MLS resistant . 17% were resistant to quinolones and 94% were resistant to tetracyclines ,

The presentation and analysis of results will be presented .
