Estudo comparativo entre a produção de fosfolipases extracelulares e proteinases do gênero Candida isoladas a partir de infecções de cavidade oral

Abstract: Resumo Introdução A habilidade da Candida spp. em produzir enzimas proteolíticas, tais como fosfolipase e proteinases, tem um papel importante na patogenicidade destas leveduras. Objetivo Determinar as espécies causadoras das infecções orais por Candida spp., além de investigar a atividade in vitro das fosfolipases e proteinases em isolados clínicos do gênero Candida, provenientes de pacientes com candidíase oral. Material e método Isolados de Candida spp., pertencentes à Coleção de Cultivos Fúngicos do Lab… Show more

“…[37] According to the present research, all isolated Candida species produce phospholipases, with C. albicans having the strongest Pz activity, corroborating the findings of another study that described phospholipae production in 61.42% of C. albicans isolates, in addition the majority were considered as strong producers. [37] Our findings regarding Pz [17,30,39,40] and hemolytic activities [21,39] in PLHIV are consistent with the findings of several previous studies.…”

“…Other virulence factors that Candida species may exhibit are the production of proteinases and phospholipases that facilitate the invasion of hyphae into the epithelium. In the case of proteinase, host protein degradation occurs by hydrolysis of peptide bonds, both those located on the mucosal surface and those related to the immune system (immunoglobulin, complement system proteins, and cytokines); and in the presence of phospholipases, phospholipid hydrolysis occurs resulting in the disintegration of cell membranes 8,9,21 .…”

“…However, not only host-related factors can cause candidiasis, but also the virulence factors of these microorganisms, including secretion of hydrolytic enzymes (phospholipases and proteinases), toxins, hemolysins, and adhesion and biofilm formation capacity [8][9][10] .…”

“…Cepas resistentes de Candida spp. apresentam maior produção de enzimas hidrolíticas como fosfolipase, proteinase, hemolisina com atividade enzimática que varia entre alta e moderada (ANDREOLA et al, 2016;ELLEPOLA et al, 2016;MENEZES et al, 2016;DABIRI et al, 2018), entretanto, a interação entre a produção destas enzimas com algumas substâncias antifúngicas ainda não foi elucidada (UYGUN- CAN et al, 2016).…”
