THE ROLE OF EXTRACELLULAR DNA IN MAINTENANCE OF BIOFILMS FORMED BY E. COLI, H. INFLUENZAE, K. PNEUMONIAE, P. AERUGINOSA, S. AUREUS, S. PYOGENES AND A. BAUMANNII George V. Tetz & Victor V.

It is known that bacteria within biofilms are much less susceptible to antibiotics particularly because of poor antimicrobial penetration through surface film that covers microbial community and inactivating role of extracellular matrix. Combined effects of DNase (Enzyme for digesting single and double-stranded DNA) and antibiotics on established biofilms of different unrelated bacteria were displayed. A Combination of antibiotics with DNase I resulted in significant decrease of established biofilm biomass compared to the reduction of biomass achieved when antibiotics or DNase I were used alone.

Our results confirmed a possible existence of H. pylori in drinking-water biofilms.

ANALYSIS AND IDENTIFICATION OF THE BIOFILM WOUND MICROFLORA IN HORSE WOUNDS Samantha J. Westgate1, Steven L Percival2*, Derek C. Knottenbelt1 and Christine A.

Equine wound healing is notoriously problematic on the lower limb, specifically when biofilms are evident. Equine chronic wounds display similar characteristics to chronic wounds in humans thus these cases provide an effective model for human cases. Whether wounds are caused by trauma or surgery their high prevalence is of concern and treatment can be both challenging and costly. Biofilms are considered detrimental to normal healing in non-healing and infected chronic wounds because of their recalcitrant nature towards antimicrobial agents. Biofilms are also known to be resistant to the effects of the immune system. Because of this fact more research in the area of chronic wounds and biofilms is warranted.

Culturable analysis of the microflora revealed that the majority of bacteria isolated from the chronic wounds of horses were Staphylococcus spp, Pseudomonas spp, Micrococcus spp, Enterococcus spp, Corynebacterium spp, Streptococcus spp, Bacillus spp, Aerococcus spp and Clostridium spp. Further analysis of all isolates highlighted their biofilm forming potential and antibiotic resistance profiles. Biofilms were shown to be evident in a large percentage of the chronic wounds. In conclusion these studies provide evidence that biofilms exist in the chronic wounds of horse which may well provide an underlying reason as to why a large percentage of chronic wounds are recalcitrant to antimicrobial therapies, do not heal a timely manner and often become infected.

CONCLUSIONS: Biofilms were demonstrated to be present in 80% the 30 patients undergoing surgery for chronic rhinosinusitis (CRS); none of the (control) patients without Chronic Rhinosinusitis had any evidence of biofilms.
