Abstract

Corynebacterium striatum is an emerging Gram-positive bacillus that presents tropism for thehuman microbiota however it has a high probabilityofpresenting a multidrug-resistant MDR profile In addition severalstudiesindicate its abilityto cause seriousinfections in patients with varying levels of immune compromise C striatum samples may present different virulence mechanisms such as disinfectant tolerance motility and bacterial biofilm formation This work aims to evaluate the antimicrobial activity of the hydroalcoholic extract of Psidium guajava L on MDR and MDS strains of C striatum an alternative for treatment We used the agar disk diffusion method to evaluate the susceptibility of bacterial samples under conditions of treatment with Psidium guajava L
