1
Phylum Sarcodina - Amoeba
Thrive in fresh water, salt water and soil. Many are motile, with pseudopods (“false feet”) used for locomotion. Some are parasitic species, found in animal intestines.
3
Entamoeba histolytica
Amoebic dysentery is transmitted through contaminated food and water. Amoebae spread by forming infective cysts which can be found in stools, and spread if whoever touches them does not sanitize their hands. Amoebic dysentery is most common in developing countries. Amoebic dysentery is often confused with "traveler's diarrhea", or "Montezuma's Revenge" in Mexico. Liver infection, and subsequent amoebic abscesses can occur. Blood may be present in stool.
4
Phylum Ciliophora - Paramecium
Most complex and advanced of the protozoans. Have hairlike structures called cilia which are used for movement and in feeding. Reproduce through binary fission and conjugation.
5
Acanthamoeba keratitis
Produce spiny pseudopodia as they move slowly along. 5 times the size of a human red blood cell, considered fairly large, but too small to see with the naked eye. Live in water, moist soil, mud, and decaying organic material. Feed on bacteria and other microscopic organisms. Can be found to invade human tissues – most commonly through the cornea of the eye from contact lenses. Can lead to corneal removal or removal of the full eye.
6
Trypanosoma brucei African sleeping sickness
Trypanosoma brucei and transmitted by the tsetse fly. The disease is endemic in some regions of sub-Saharan Africa. It is estimated that 50,000 to 70,000 people are currently infected, the number having declined somewhat in recent years. Symptoms in 2 stages: 1) Characterized by fever, headaches, joint pains, swelling of lymph nodes and itching. 2) Invades central nervus system and into thebrain. Causes confusion, reduced co- ordination, disruption of sleep cycle (daytime slumber, nighttime insomnia) Other modes of transmission: Mother to child infection: Crosses the placenta and infect the fetus. Laboratories: accidental infections Blood transfusion Sexual contact (might be possible, but happens rarely)
8
Phylum Chrysophyta - Diatoms
Fresh and salt water Autotrophic, contain chlorophyll. Many are encased in silicate shells or skeletons. (Can be used in toothpaste.)
9
Chlorella Used as a nutritional supplement High in essential nutrients
45% protein, 20% fat, 20% carbohydrates, 5% fibre and 10% vtimains and minerals when dried Super food!
11
Phylum Pyrrophyta - Dinoflagellates
Autotrophs, contain chlorophyll and red pigments. Can contaminate shell fish.
12
Phylum Euglenophyta - Euglena
Both heterotrophic and autotrophic. Have an eye spot which is sensitive to light. Reproduce asexually and sexually. Evolutionary link between plants and animals.
14
Kingdom Fungi
15
Kingdom Fungi Include yeasts ,moulds, and mushrooms.
Non photosynthetic plantlike organisms. Most fungi are saprobes (decomposers) and help to recycle nutrients back into the soil. Some parasitic and live off of living organisms. Secrete digestive enzymes onto food and then absorbs the nutrients Fungal cell walls contain chitin (kite-in). Produce seedlike spores to ensure distribution. Eukaryotic cells, most are multicellular Sexual and asexual reproduction
