Title

EFFECT OF ESSENTIAL OIL OF SATUREJA HORTENSIS ON INTESTINAL E. COLI ISOLATES IN BROILER CHICKENS

Pages

  25-35

Abstract

 This study was conducted to investigate the effects of diets containing different levels of Satureja hortensis essential oil on Fecal and illum microflora of BROILER CHICKS, resistance antibiotic and invitro assay activity SATUREJA ESSENTIAL OIL against E.COLI isolates. Tree hundred and twenty one-day old male BROILER CHICKS (Ross-308 strain) were used in a completely randomized design with 4 treatments, and 4 replicates were allocated to each treatment. Different levels of SATUREJA ESSENTIAL OIL in diets had not significant effects on total bacterial count and E.COLI/coliform population in faecal material at 32 days old and illum at 42 days of age (p>0.05). Also in this survey Dietary treatment had no effect on the anti-bacterial valus of thirteen antibiotics against E.COLI isolates by Disc diffusion method (p>0.05). Most of the E.COLI isolates were resistant to antibiotics, the most efficient being Penicillin, Riphampicin and Erythromycin. Chemical analysis of this oil by capillary GC showed as the main constituent carvacrol (%37.18). An invitro assay measuring the antimicrobial activity of SATUREJA ESSENTIAL OIL in disc diffusion method, the highest inhibition areas were observed for the amount of 5μl essential extract. The results are suggesting that SATUREJA ESSENTIAL OIL for the amounts of 1μl and 2μl has antibacterial effect on E. coli isolates similar to the best antibiotics such as Streptomycin, Tetracycline and Neomycin.The results of MIC and MBC showed the high anti-microbial effect of SATUREJA ESSENTIAL OIL. It seems the presence of carvacrol caused the strong anti microbial effect of this oil.
