Effect of algae and plant lectins against bacterial biofilm formation

Prophylactic outcomes of casbane diterpene in Candida albicans and Candida glab...

Biofilms are surface associated communities of microorganisms embedded within a self-produced extracellular matrix and adhered on inert and biotic surfaces. These biological consortia are considered the most prevalent growth form of microorganisms. Biofilm formation is a potent virulence factor for a number of Candida species, as it confers significant tolerance to antimicrobial therapy, primarily by limiting t...

Casbane diterpene activity on mixed biofilms of P. aeruginosa and Candida species

Casbane diterpene as a promising natural antimicrobial agent against biofilm-as...

Croton nepetaefolius is a native plant from northeastern Brazil that belongs to the Euphorbiaceae family. The biological action of this plant has been extensively explored, being the secondary metabolites responsible for its properties alkaloids, diterpenes, and triterpenes. This study aimed to evaluate the ability of casbane diterpene (CD), isolated from the ethanolic extract of C. nepetaefolius, to inhibit mi...

Evaluation of leguminous lectins activities against bacterial biofilm formation

Biofilms are composed by microbial cells that are irreversibly associated with a surface and enclosed in a matrix of polymeric material. Lectins are sugar binding proteins of non immune origin that agglutinate cells and ⁄ or precipitate glycoconjugate molecules. Due to their capacity to bind and recognize specific carbohydrates, lectins can be a potent tool in biofilm studies. The search for potential phytochem...

Casbane diterpene as novel and natural antimicrobial agent against biofilm infe...

Croton nepetaefolius is a plant native from northeastern Brazil and belongs to Euphorbiaceae family. The essential oil of this plant is widely used in folk medicine from the treatment of gastrointestinal disorders to the use as an antiseptic agent, with an antifungal action scientifically proven. The action of this plant has been extensively explored by the scientific community, being the secondary metabolites,...

Perfil de proteases de lesões cutâneas experimentais em camundongos tratadas co...

O objetivo deste estudo foi determinar o perfil de proteases em lesões cutâneas experimentais tratadas com a lectina isolada das sementes da Canavalia brasiliensis (ConBr) livre e conjugada com o seu açúcar específico. Lesões cirúrgicas foram produzidas assepticamente na região dorsal de camundongos (n=120), divididos de acordo com o tratamento empregado: Grupo NaCl (NaCl 150mM), Grupo manose (manose 100mM), Gr...
