“…Contrary to this assertion, synergism has been observed by the combination of the antifungal drugs terbinafine and fluconazole for control of Pythium insidiosum in vitro (CAVALHEIRO et al, 2009). Further, in contrast to the non-efficacy of antifungal agents on oomycetes, intravenous regional perfusion (IRP) using miconazole (WORSTER et al, 2000) and amphotericin B is reportedly a successful therapeutic for ECP (CARVALHO et al, 2016;DÓRIA et al, 2012DÓRIA et al, , 2015, which highlights the lack of knowledge regarding the mechanisms of action of these drugs on oomycetes. It is likely that the main mechanism of action of antifungal agents against Pythium insidiosum is modulation of the host's immune system against pathogens, either by recruiting phagocytes or releasing cytokines (BEN-AMI et al, 2008;MESA-ARANGO et al, 2012).…”
