Sensibilidade de cepas Staphylococcus aureus resistentes a beta-lactamicos ao óleo essencial de alecrim-pimenta

Abstract

In present days, dairy farming is one of the sectors that shows continuous growth generating high profitability to the country, but it has difficulties, since the herd can be affected by diseases such as mastitis. Mastitis is characterized by the inflammation of the mammary gland causing the fall of animal’s production, and the successive application of antibiotics can be a important reason for ultiresistance’s increase and most of times it can’t cure the disease. Studies have started to find alternative solutions for the control of multiresistant microorganisms and the use of essential oils have obtained recognition, highlighting oil of rosemary pepper, fourteen Staphylococcus aureus strains were used in the disc diffusion test with different concentrations of the oil – 0μl, 30μl, 60μl, 120μl and 240μl. The pepper-rosemary oil presented low activity against the isolated strains, being the 240 μl concentration more efficient, the oil efficiency was variable according to each genetic group analyzed.
