Title

EFFECT OF GROWTH TEMPERATURE AND BIOFILM AGE ON THE RESISTANCE OF SALMONELLA TYPHIMURIUM BIOFILMS TO BACTERIOPHAGE

Pages

  173-182

Abstract

 Background & Aims: SALMONELLA TYPHIMURIUM is among the most important food-borne disease. This study was conducted to investigate the anti-biofilm effect of the S. Typhimurium phage against Salmonella formed in CHICKEN meat model.Materials & Methods: The effects of different phage concentrations (104, 106 and 108 PFU/mL) with two contact times (10 and 20 min) on one and 7 days old BIOFILM adhered to stainless steel coupon in CHICKEN broth at 15, 8 and 4°C were evaluated.Results: The results showed that the bacteria had an ability to adhere to the coupons and form BIOFILM in CHICKEN broth, the BIOFILM levels were significantly (P£0.05) higher at 15°C for 7 days. Increasing the phage concentrations, resulted in no significant BIOFILM removal properties and the activity was not influenced by the phage contact times. The anti-biofilm activity was influenced by the age of BIOFILM, in this case, one day-old BIOFILM was more sensitive than 7 days old.Conclusion: From the study it can be concluded, that in CHICKEN model, the phage exhibited BIOFILM removal activity on Salmonella only at high concentrations, then the use of a combination of methods to control BIOFILM is recommended.
