| Question | Answer |
|---|---|
| DNA Viruses Parvoviruses | single stranded, smallest of DNA viruses, best know to cause animal disesases, cause aplastic anemis, dna |
| hepadnaviruses | cause liver infections in humans and animals papoviruses circular, double strand of DNA; linked to cervical cancer, produce tumor-like lesions in humans and animals, dna |
| adenoviruses | responsible for respiratory, gastrointestinal, and genitourinary infections; and severe eye infections, dna |
| Herpes viruses | large, posess latency, cause infectious mononucleosis, dna |
| poxviruses | largest DNA virus, cause smallpox and benign tumors in humans, dna |
| reoviruses | causes severe vomiting and diarrhea; cause travelers diarrhea, responsible for infant deaths in developing countries, RNA |
| Picornaviruses | smallest RNA viruses, cause polio and common cold, can cause Hepatitus A, RNA |
| Togaviruses | transmitted mostly by arthropods (spiders, ticks); causes rubella (German measles), RNA |
| Flaviviruses | can cause Hepatitus C and liver cancer, RNA |
| Orthomyxoviruses | have enveloped and helical symmetry, responsible for causing the flu (influenza), RNA |
| Paramyxoviruses | highly pleomorphic (assume different shapes), can cause measles, mumps, and various respiratory infections |
| Rhabdoviruses | human rabies |
| Bunyanviruses | cause kidney disfunction and human encephalitis, RNA |
| Retroviruses | cause AIDS, RNA |
| Chlorophyta | some are unicellular, but most are multicellular; contain chlorophyl, reserve product is starch, Algae |
| Euglenophyta | unicellular, motile, no cell wall, reproduce asexually; reserve products are carbs and oils; contain chlorophyl, Algae |
| Chrysophyta | unicellular, abundance of carotenes, contain chlorophyls, reserve products are oils,two part overlaping cell wall, Algae |
| Phaeophyta | multicellular, superficially resemble plants, contain carotenes, reserve products are carbohydrates and oil, Algae |
| Pyrrophyta | unicellular, move rapidly through liquid responsible for red tides that occur in coastal waters of US and Canada in summer and early fall, reserve products are starches and oils, Algae |
| Rhodophyta | non-motile, uni or multicellular, added to icecreams, jellies, and jam;used as a solidifying agent in culture media; reserve product is starch, Algae |
| Sarcodina | move by pseudopodia (false feet), free-living parasitic amoebas, include (Entamoeba histolytica), slowest moving protozoa, Protozoa |
| Mastigophora | moves by one or more flagella, cause human infections, intestinal flagellates have sucking disks, Protozoa |
| Ciliata | move by cilia (short hairlike appendages), which surround plasma membrane; cilia help take in foods by creating waves, Protozoa |
| Sporozoans | complex life cycles, nonmotile, all cause infectious diseases, Protozoa |
| Zygomycota | mainly found in soil, nonseptate hyphae, ex. common bread mold, Fungi |
| Ascomycota | includes yeasts and some molds, have septate hyphae, reproduce asexually, Fungi |
| Basidiomycota | include rusts, common mushrooms; reproduce asexually or sexually, Fungi |
| Deuteromycota | cannot reproduce sexually, ex. Penicillin, known as Class of Leftovers, Fungi |
| Spirochetes | Cause Syphillis and lime disease; helical, motile aqueous environment, in association with human or animal hosts, Bacteria |
| Aerobic/Microscopic | helical uibriodgramnegative bacterial Slightly curved or posses multiple helical turns, motile by flagella fresh or coastal water, Bacteria |
| Gram-negative aerobic | rods or cocci aerobic and never fermentative; cause gonorreah and whooping cough widely distributed in nature, Bacteria |
| Facultatively anaerobic | gram-negative rods if motile, all have pertrichous flagella, simple nutritional requirements soil, water, intestional tracts of animals and humans, Bacteria |
| Anarobic gramnegative | rods can be isolated from sewage; straight, curved, or helical;motile or non-motile intestional tracts of animals and humans, Bacteria |
| Rickettsias and Chlamydias | cause blindness and typhus mouth and intestines, Bacteria |
| Mycoplasmas | smallest free living bacteria;no cell wall;cause atypical pneumonia animals, plants and humans, Bacteria |
| Gram-positive Cocci | aerobic or anerobic, spherical cells;differentiated by atmospheric requirements humans, animals |
| regular gram positive rods | obligate or facultative anaerobes;complex nutritional requirements vagina, yogurt, pickles, Bacteria |
| Mycobacteria | aerobic, acid-fast rods;cause tuberculosis and leprocy soil, air, humans, Bacteria |
| streptomycetes | aerobic, produces spores, important source of antibiotics soild, Bacteria |
| nacardioforms | aerobic, gram-positive, some are partially acid-fast lungs, skin, Bacteria |
| methogens | generate methane, anaerobic enviorments, Archaea |
| extreme thermophiles | thrive in extreme heat;highly acid enviorments, Archaea |
| extreme halophiles | require high concentration of NaCl, Archaea |
