Farmers in Central and South America are most susceptible to chromoblastomycosis due to F. There is, however, some evidence supporting the hypothesis that sialic acids could help fungal cells to escape host defenses by protecting them against phagocytosis Oda et al.

Melanization of Cryptococcus neoformans affects lung inflammatory responses during cryptococcal infection. These enzymes have a potential role in fonsecwea microbial infections Jost et al. Importantly, peroxidase-containing granules in neutrophils were found to be fused with the parasitophorous vacuole, indicating that the toxic products of H 2 O 2 cleavage are involved in F.
