Abstract:

The oral microbiota of domestic cats is composed of several microorganisms that play an important role in the disease and health of the animal. Recently, some studies have shown the strains of Pasteurella isolated from the oral cavity of domestic cats�?¢�?�?�?�? present antimicrobial resistance. In this context, the essential oils (EOs) are presented as a therapeutic alternative to this antimicrobial resistance. Thus, the study aimed to evaluate the antimicrobial action of EOs from Citrus bergamia (bergamot), Anthemis nobile (roman chamomile), Cymbopogon citratus (lemongrass), Copaifera officinalis (Copaiba), Eugenia caryophyllus (clove) and Melaleuca alternif�?�?�?³lia (tea tree) against Pasteurella spp. isolated from the oral cavity of healthy cats and with gingivitis. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined for each isolate by broth microdilution technique, from the maximum concentration of 3200 �?�?�?µg mL-1. The strains of Pasteurella spp. were sensitive to the EOs of cloves (MIC= 200 to 400 �?�?�?µg mL-1, MBC=200 to 800 �?�?�?µg mL-1), lemongrass (MIC= 50 to 400 �?�?�?µg mL-1, MBC= 50 to 400 �?�?�?µg mL-1), melaleuca (MIC= 400 �?�?�?µg mL-1, MBC= 400 to 1600 �?�?�?µg mL-1) and roman chamomile (MIC= 200 to 1600 �?�?�?µg mL-1, MBC= 400 to 1600 �?�?�?µg mL-1). However, the Pasteurella spp. isolated of domestic cats were not sensitive to copaiba and bergamot EOs. EOs showed the highest antimicrobial activity against the strains of Pasteurella spp. isolated from cats with gingivitis. These results confirm the potential of the antimicrobial action of some essential oils for treatment of oral infections.
