摘要：

Enterococcus faecalis is a Gram-positive bacteria considered an important emergent nosocomial pathogen. mainly due to its resistance to most antibiotics and responsible For a variety of human infections. In order to discover new bioactive secondary metabolites from microbial sources, the objective of this work was to evaluate the antimicrobial activity of the crude extract obtained from Paecilomyces variotii for eight clinical isolates of E. faecalis by the disk diffusion method. The results showed that all clinical isolates were inhibited by fungal extract, with inhibition zones ranging from 25 to 35.25 mm. In addition, the results also revealed resistance, in the microorganisms test, to antibiotics such as ciprofloxacin, cotrimoxazole, erythromycin, gentamicin, oxacillin and tetracycline.
