El objetivo de este trabajo fue determinar la concentración mínima inhibitoria (CMI) y la concentración mínima bactericida (CMB) de nanopartículas de plata (NpAg) obtenidas por síntesis verde con extracto de hojas de Leea coccinea sobre cepas de Staphylococcus aureus y aislados resistentes a meticilina. Se evaluaron tres lotes de NpAg de Leea coccinea sobre dos cepas S. aureus y dos aislados resistentes a meticilina, por el método de diluciones seriadas, para la determinación de CMI y CMB. Las NpAg de Leea coccinea mostraron actividad antibacteriana sobre las cepas y los aislados resistentes de S. aureus, con valores de CMI para los tres lotes que coincidieron en su mayoría en 0,03 mg/mL para todas las cepas y los aislados. En los valores de CMB en los tres lotes concordaron y se observaron diferencias entre los valores para los aislados resistentes (0,485 mg/mL) y las cepas (0,12 mg/mL). Estos resultados demuestran la actividad antibacteriana de las NpAg de Leea coccinea sobre este patógeno, destacan sus potencialidades como alternativa ante la resistencia a antibióticos y crean las bases para otros estudios con vista a una futura aplicación como antibacteriano.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT Infections caused by Staphylococcus aureus represent a problem for animal and human health. This work was aimed to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of silver nanoparticles (NpAg) obtained by green synthesis with Leea coccinea leaf extract on Staphylococcus aureus strains and methicillin resistant isolates. Three batches of NpAg from Leea coccinea were evaluated on two S. aureus strains and two methicillin resistant isolates, by the serial dilution method, for MIC and MBC determination. NpAg from Leea coccinea showed antibacterial activity against resistant strains and isolates of S. aureus, with MIC values for the three batches mostly coinciding at 0.03 mg/mL for all the strains and isolates. MBC values in the three batches agreed and differences were observed between the values for resistant isolates (0.485 mg/mL) and strains (0.12 mg/mL). These results demonstrate the antibacterial activity of NpAg from Leea coccinea on this pathogen, demonstrating its potential as an alternative to antibiotic resistance and creating the basis for further studies for its application as an antibacterial agent.]]></p></abstract>
