Antibacterial potential of essential oils against planktonic and sessile cells of Escherichia coli isolated from diarrhea cases in swine

Escherichia coli is a pathogen associated with infections in piglets the post-weaning phase, its pathogenicity related to animal's susceptibility bacterial enterotoxins. The objective of present study was determine EOs activity against E. strain, form planktonic and sessile. Although Disc-Diffusion tests Minimum Inhibitory Concentration, do not fully corroborate other analyzes this study, it noticed bacteria inhibition. were prepared at 0.4%, 0.8% 1.0% for tests. tested effective cells (p<0.05). As sessile cells, most significant result inhibition 100% concentration Cymbopogon citratus EO. there resistance some treatments, demonstrated capacity, constituting promising alternatives control coli, especially cells.
