Common characteristics of 3 types of fungi
Eukaryotic, have cell wall, composed of polysacharide called chitin, chemoheterotrophs
Types of fungi (spores)
Sponrangiospores (inside the sac)
Chlaymdospores (inside the hyphae)
Conidiospores (spores nott enclosed in a sac)
Characteristic of mold
Multicellular, filamentous, aerobic (w/oxygen), reproduced by spore, asexual/sexual
What are Hyphae's that molds are composed of
Septate hyphae - divided into cells by crosswall
Aseptate hyphae - no septum, aka coenocytic (multi-nucleated)
Ex. Dimorphic pathogenic fungi
Candida albicans, coccideodesimmitis (valley fever), hisplasma capsulation (lung infection)
Growth requirement of fungi over bacteria
Acidic pH, tolerates salt/sugar concentrations, high osmotic pressure, requires less nitogent for growth
Disease of GI Protozoa
Giardiasis - Giardia, Amoebiasis - Entamoeby histolytic & cryptosporidiasis - sytosporidium
PSP - Paratytic shellfish poisoning & Neurotoxin - secreted by dinoflagellate protozoa
Food intoxication of Protozoa
Worm like parasites, egg & larve, infectous to humans & animals i.e. flukes, tapeworm and roundworm
Multicellular animals, freeliving & parasites, circulatory digestive, nervous, multiple host & produce by egg, larve & adult worms
Characteristics of arthropods
Jointed legs, segmented body covered in exskeleton, & transmission of diseases
Infected with pathogen, reproduces inside arthropod & transmitted to another host through bite with arthropod
Carry pathogen on their external body parts, wings & leggs & transmit to another host
Ex: of Vector borne diseases
Mosiquito (B) - malaria & West niles virus, ticks - lyme disease & house fly - transmitts, tyhoid, & jauntis
