Sorry if i intrude but there are several strains of yeast which may invade the mucus lining and infect all around the body.
Candida is probably one of the most easiest fungies to cure and since antibiotics (azole, triazole) work on a microbial level even fungus die of it but since fungi is stronger than probiotics it's recommended not to take on a sugary diet directly after an antibiotica treatment since the probiotics are surely to fail against yeast on the starting line, that's why people are so cynical about antibiotics cause the reinvention of probiotics into the bowels takes days before you can eat anything sugary again to not disturb the flora.
And if there is leaky gut present the yeast will reinfect it since inflammations in the GI tract takes months to heal.
The ideal balance of probiotics/fungi in the bowels are 85/15%, other strains of more difficult fungi include Aspergillus (Niger, Flavus, Fumigatum), Penicillum, Fusarium et cetera.
To treat those you HAVE to go antibiotics, maybe even intravenous for a week or more like liposomal Voriconazole.
The difficulty of the harder fungis is that they are aerobic and aren't as sensitive to oxygenising while Candida is anaerobic and easier to kill with both anti-fungals AND oxygen promotion (H2O2 = brands like Hydrogen Peroxide).
But some antibiotics with essentially anti-microbial properties might not work against Candida or fungi at all.
