Biofilm production by organisms

Beneficial biofilms developed by nitrogen fixing bacteria and P - solubilising fungi in vitro conditions and also used as biofertilizers in non - leguminous crops and also observed that the bacteria colonized fungal mycelia to form biofilms. The biofilms showed high rates of biological nitrogen fixation and organic acid production which directly influences the synthesis of indole acetic acid like substances than microbes when used as monocultures. (Seneiviratne et al., 2003).

Ventilator-associated pneumonia is defined as nosocomial pneumonia occurring more than 48 hours after patients have received mechanical ventilation. VAP in a critically ill patient significantly increases risk of mortality, ventilator time, length of stay and cost of care. The Endotracheal tube is a favourable site for biofilm formation. They are adherent cells which are embedded within a self-produced matrix of This EPS matrix impedes the normal functions of antibodies and the phagocytic cells of the immune system and leads to increased resistance to antibiotics.

Escherichia coli is responsible for a wide variety of intestinal infections, showing increasing antimicrobial resistance. Antimicrobials resistance in biofilm-forming isolates contributes to bacterial persistence which may lead major public health concern and treatment problems. The aim of this study was to study the antimicrobial resistance profile of E. coli with reference to biofilm production to study the possible relationship among E. coli isolates from cattle and their farm environment. Out of 64 samples 34 (53.12%) samples were confirmed as E. coli, whereas 16 (47.

Mangiferin was isolated from Vietnamese Mangifera indica leaves. Its antimicrobial activities against the oral bacterium Streptococcus mutans GS-5 were evaluated in terms of inhibition of acid production and biofilm formation. The obtained results indicated that mangiferin at the concentration of 0.5 mM clearly inhibited acid production by this organism with a final pH value of 5.2 compared to 3.9 of the control. The reduction in biofilm biomass was found up to 92 % when it was treated with 1.0 mM mangiferin. Thus, mangiferin possesses moderate anticaries activity against S. mutans GS-5.
