DETECTION OF BIOFILM PRODUCTION BY STAPHYLOCOCCUS AUREUS AND IN-VITRO INHIBITION OF BIOFILM USING SERUM ANTIBODIES
Journal Title: Matrix Science Medica (MSM) - Year 2017, Vol 1, Issue 2
Abstract
The biofilm producing ability of Staphylococcus aureus has been implicated for development of different diseases in animals and humans. The presence of biofilms makes the bacterial population resistant to a wide range of antibiotics. Biofilms are also antigenic structures of the bacterial population. Therefore, the present study was planned to evaluate the biofilm-producing ability of S. aureus and in-vitro inhibition of biofilm production using serum samples from rabbits immunized with biofilm-producing S. aureus bacterin-toxoid. A total of 64 S. aureus isolates were harvested from lactating cows and buffaloes suffering from clinical and sub-clinical mastitis. The biofilm-producing ability of S. aureus isolates was determined by tube method and micro-plate assays. The rabbits were vaccinated using strong biofilm producing S. aureus bacterin-toxoid. The ability of serum antibodies to inhibit in-vitro biofilm production was assessed by performing a biofilm inhibition assay. The results showed that 71.87% and 56.25% ofthe isolates were positive for biofilm production in tube method and micro-plate assays, respectively. The serum samples collected at days 30, 45 and 60 post-immunization completely inhibited the biofilm production by S. aureus. Our results suggested that both micro-plate assay and tube method can be used for determination of biofilm production, however micro-plate assay is quantitative, more accurate and reliable. The study also concluded that the antibodies produced against biofilm producing S. aureusbacterin-toxoid seems helpful to avert the attachment of bacteria, which may further implicate the better control of chronic infections.
