Infectious diseases continue to be one of the biggest health problems in the world, affecting millions of people annually M. abscessus and other species of rapidly growing mycobacteria (RGM) are naturally resistant to antimicrobial compounds and disinfectants because they have an impermeable cell wall composed by peptideoglycan and mycolic acids. These RGM are responsible for various hospital outbreaks worldwide, causing lung infections in patients with cystic fibrosis, chronic lung disease (bronchiectasis, nodules and cavitations), post-surgical infections and skin and soft tissue infections in immunocompromised patients. The resistance of M. abscessus (Mabs) to the medications used in current therapy challenges the search for new treatment strategies. Previous studies on the search for new natural compounds with antimicrobial action highlighted the potential of Bixa orellana (urucum). The seeds of this plant are already used in folk medicine for treating heart disease, gastrointestinal problems and respiratory infections. In this study, we evaluated potential anti-inflammatory activities of hydroalcoholic (BoEH) and ethyl acetate (BoEA) extracts of B. orellana leaves, using a murine model of peritonitis induced by heat killed Mabs. C57BL/6 mice were orally treated with different concentrations of BoEH or BoEA. After one hour, peritonitis was induced by inoculation of 1x108 CFU of heat killed Mabs. BoEH and BoEA inhibited the migration of total leukocytes (Figure 1A-B), migration of polymorphonuclear cells (Figure 1C-D) and mononuclear cells (Figure 1E-F) into the peritoneum in the periods analyzed 4 and 24 hours after the induction of peritonitis. Our results suggest anti-inflammatory actions of the extracts tested, indicating this plant as natural source of compounds with potential for pharmacological and biotechnological applications.
