    “Evaluación del efecto antibacteriano de los extractos de plantas medicinales del Ecuador”
    (Universidad Técnica de Ambato - Facultad de Ciencias de la Salud - Carrera de Laboratorio Clínico, 2019-10-01) Núñez Hernández, Erika Tatiana; Gudiño Gomezjurado, Marco Esteban Dr.
    In the last decade, worldwide data shows the continued increase in resistance of microorganisms to antimicrobials. All this is due to the abuse, abuse of these substances by humans and the use of antibiotics during agricultural and veterinary practices. So much so, that according to the World Health Organization (WHO) the situation is emerging at the health level, with the consequent socioeconomic impact. Therefore, new alternatives have been sought and one of them is the plant species. Ecuador, owning a great diversity of flora, fauna and ethnic diversity, Aboriginal peoples have used plants to mitigate and cure ailments. Against this background, we set out to evaluate the antimicrobial activity of 11 plant species against bacteria. Of these, Croton lechleri and Eucalyptus globulus Labil had antibacterial effects in the presence of log10 7.8 CFU of S. aureus ATCC 25923 and log10 8.48 CFU of L. monocytogenes ATCC 19115 with a minimum bactericidal concentration of 2.5 mg for S. aureus ATCC 25923 and 5 mg for L. monocytogenes ATCC 19115 with C. lechleri and 5 mg for S. aureus ATCC 25923 and 0.625 for L. monocytogenes ATCC 19115 with Eucalyptus globulus Labil.
