intoxication due to ingestion of foods, typically grains, contaminated with fungal toxins (mycotoxins) - aflatoxin
atopic hypersensitivity due to exposure to fungal antigans (allerign becouse of the spores they produce
all yeast produce- conidia that is blown out from the mother cell, either a yeast or hypha (tip of the hypha is the active growing part
produced basipetally as part of a chain by septation and disarticulation of a conidiiogenous hypha
blastic conidium produced basipetally and extruded from a conidiogenous cell (phialide)
(poroconidium) produced through minute pores in the wall of a conidiophore or previously formed conidium
blastic conidium produced basipetally in chains or balls from the tip of a conidiogenous cell (annellide) wherein a scared tip is left between each successive spore
zygomycota (water fungi)
contaminants and adventitious pathogens characterizied by rapid growth and aseptate hyphae
asomycota (sac fungi)
contaminants and, advantitious and overt pathogens-advanced forms phylogenetically and largest number of species
basidiomycota (club fungi)
mushrooms, puffballs, rusts, and smuts; highest forms phyogenetically, no animal pathogens, some species cause mycotismus and mycotoxicosis
deuteromycota (fungi imperfecti)
sexual (perfect) mode of reproduction unknown, most animal pathogens in this group
deuteromycota class; conidia borne on conidiophores or directly on hyphae (moniliaceae and dematiaceae)
characteristic of some fungi wherin they exhibit two different somatic forms depending upon environmental conditions temp isthe main factor
fungi main function of spore
dissemination (dispersial) not extremely resistant they are problematic b/c they disperse into the air and are inhealed
eucaryotic, anerobic or faculative, saprophytic and hetertropic, and are usually filamentous, branched somatic structers with rigid cell wall
most fungal infections are
exogeneous in origin (environment) except tinea versicolor and candidosis
