In this study,120 vaginal and urine samples were collected from patients suffering from severe to moderate vaginitis and urinary tract infection who attending to Babylon Hospital of Delivery and Maternal in hilla city through a period of three months. It was found that only seven isolates of Streptococcus agalactiae were identified. All isolates underwent culture and biochemical tests to confirm diagnosis, and it was reveled that the all isolates gave the same cultural and biochemical characters. However, other types of bacteria and yeasts were also isolated.
The effect of some antibiotics on Streptococcus agalactiae was investigated, and the results showed that all isolates were found that 42% of isolate are resistant to B-lactam antibiotic ,only 12.5 % are resistant to cephalosporine ,46 %are resistant to aminoglycoside , about 72% are resistant to macrolide and all isolate are resistant to cloramphenicol.
Some virulence factors of bacteria were also studied, and the results showed that all bacterial strains possessed capsules, which were regarded as the most virulent factor of the bacteria. The most characteristics of Streptococcus agalactiae is Gram-positive coccus which appears in chain or pair, catalase negative, facultivaly anaerobic bacteria, contain capsule and resistance to bacitracin. In respect of the ability of the isolates to produce Haemolysin, Siderophore, and Extracellular proteases, the results of the work showed that all the isolates were able to produce bacterial haemolysin, but were not able to produce siderophore and extracellular proteases.
