|
Entameobas histolyglica |
Ameoba, in contaminated water, cysts enter stomach and become trophozoite, causes damage and dysentery, intestinal parasite, rare |
|
|
Acanthameoba species |
Ameoba, rare, treated with ani-protozan drugs, first case in Texas 1980, called keratitis |
|
|
Trichomonas vaginalis |
STD, self limiting, spin like helicopters in fresh urine, shaped line a pear |
|
|
Giardia lamblia |
Cysts in water, small intestine, before trophozoites and cause fanfare and dysentery, cysts in stool, intestinal parasite |
|
|
Typanosomes (2 Strains) |
T cruzi - S America, vector is missing bug, parasite gets into blood (hemoflaggelate), goes to heart and damages valves, deadly, more common in children T gambiense - Africa, vector is tsetse fly, hemoflaggelate, goes to brain and cause coma and leads to death, African sleeping sickness |
|
|
Balantidium coli |
Rarest, only cilliate pathogen to humans, cysts in H2O, get into intestines, become trophozoites, cause damage and diarrhea |
|
|
Apicomplexans |
Complex life cycles, 2 hosts |
|
|
Plasmodium (4 Species) |
cause malaria, vector is anopleles mosquito (1st host), enters human blood (2nd host), every 24hrs RBC's burst causing fever and leads to death |
|
|
Toxoplasma gondi |
Hosts - domestic cats and humans, disease called toxoplasmosis, cat feces have oocytes, gets ingested and goes to brain causing damage, will kill placenta in pregnant women |
|
|
Cryptosporidium |
1980 - 400k people infected in Milwaukee leading to diarrhea, cysts in cow feces gets into drinking water, not deadly, self limiting |
|
|
Pneumocystis |
Old "Protozan", now Fungi, fungi pneumonia is #1 looker in immune compromised systems |
|
|
Characteristics of fungi |
Over 100k species, all chemoheterotrophs, absorb organic food with exo enzymes, mostly multi cellular (yeast unicellular), few human diseases (in immune compromised systems), reproduce sexually(rare) + asexually(common), major cause of food spoilage |
|
|
Benefits of fungi |
Biodegrade organic material, myocorrhizae - soil fungi, symbonic roots increase absorption of water, food - mushrooms, cheese, beer, drugs - penicillin, antibiotics |
|
|
General characteristics of fungi |
Aerobic (mold) + anaerobic (yeast), chitin cell walls, fungi classified into phylum based on type of sexual spores or asexual spores |
|
|
Mycology |
Study of fungi |
|
|
Mycellium |
Reproductive/Vegatitive |
|
|
Hyphae |
Branching filaments that make up the mycellium |
|
|
Septate |
Spores or hyphae that possess or lack a septa ton divide cells |
|
|
Fungi exo enzymes |
Cellulase, petinase, ligninase - can live on complex carbs |
|
|
Fungi morphology - yeast |
37C, low O2, high CO2, vaginal yeast, thrush |
|
|
Fungi morphology - mold |
25C, high O2, low CO2, farmers lung |
|
|
Teleomorph |
Method of making spores sexually - rare, made in distress, genetic recombo, variety in zygote gives advantage asexual - common, cloning, no variety |
|
|
Fungi sexual spore type zygomycota |
Fusion fungi, two fungi fuse, produce zygote, zygote=spore |
|
|
Fungi sexual spore type ascomycota |
Sac fungi make a sac (ascus) that had spores |
|
|
Lichens |
Don't belong to any kingdoms, symbionic relationship between algae and fungi Lichens live in barren environments, due in the presence of pollution |
