Biofilm Producing by Staphylococcus aureus and Lactobacillus spp. Isolated from Urogenital Tract Infections of Women

To assess the ability of vaginal lactobacilli and staphylococci that associated with urinary tract infection to form biofilm. out of sixty vaginal samples, thirty samples were positive culture for Staphylococcus aureus which were cultured on congo red agar medium for determined their ability for biofilm formation, only 19 isolates were able to form biofilm. whereas out of sixty vaginal samples fourty two samples were positive culture for Lactobacillus spp., 16 isolate were able to form biofilm. Genetic detection of icaD gene by PCR of Staphylococcus aureus isolates was don and 86% of isolates give positive result of this gene. Not all isolates of vaginal lactobacilli and staphylococcus were able to produce biofilm.
