Hongos resupinados del Parque Nacional Podocarpus como agentes de control biológico de bacterias de interés clínico

Abstract

Abstract: In Ecuador, the knowdlege about the diversity of fungi and their biotechnological potential is scarce, especially those microscopic fungi such as resupinated fungi. For this reason, through in vitro tests the antibacterial capacity of molecularly characterized resupinated fungi from the Podocarpus Cajanuma National Park was evaluated against Gram-negative bacteria of clinical interest. For this, antagonism tests were performed through the Muller Hinton agar diffusion method under the criterion of the diameter of the inhibition halos, based on a reference value determined by the CLSI with antibiotic control. The results indicate that several fungi such as Oliveonia sp. did not show antibacterial activity, however Gloeocystidiellum sp. has inhibition capacity with halo values between 20 and 23 mm against different Escherichia coli pathotypes. This last one is presentes as a potential source of a specific antibiotic to Escherichia coli.
