RESUMO:

The worldwide concern regarding the indiscriminate use of antimicrobials used in animal creations, and their consequences due to these excesses are unquestionable. In fact, the activity of active principles has been hampered by the appearance of superbugs, which are becoming more resilient every day. Several factors are related to the increase of bacterial resistance, among them, it is of fundamental importance to highlight the bacteria that have the capacity to form biofilms. Numerous studies indicate that, in this formation, bacteria tend to be more resistant due to their highly organized structure and, consequently, their greater protection from external attacks. Several studies aim to find antimicrobials with equivalent elimination power of important bacteria in the animal sector. Thus, the main objective of the present study was to find an essential oil (OE), which to present relevant bactericidal effect against Escherichia coli (E. coli) isolates in planktonic and sessile form (biofilms). For this, two OEs extracted by hydrodistillation process, and two commercial OEs were selected. With these OEs, tests were performed to verify the efficacy against the bacterium in its planktonic and sessile (biofilm) form. The OEs were tested in three concentrations: 0.4%, 0.8% and 1%, and control (solution without oil). The present study demonstrated the bactericidal capacity of OEs, and with this, a great potential of use as an alternative to antimicrobials in animal production.
