Unit 5 bacteria
atypical bacteria, fungi, asexual reproduction
| Question | Answer |
|---|---|
| Atypical bacteria | Mycoplasma pneumonia, Richsettia Rickittii, chlymydia trachomatis |
| Mycoplasma pneumonia | No cell wall and is gram negative |
| Mycoplasma pneumonia treatment | Treat with dioicycline |
| Why is mycoplasma pneumonia atypical | because it does not have a cell wall. The cell wall gives organisms its shape and ridgity. This organism is "L" shaped. |
| Ricksettia Rickittii discovered | Rocky Mountain spotted fevver-dog ticks, first discovered in a lab in the Rocky mountains. |
| Ricksettia Rickittii is from an | oblonggotic intracellular parasite- |
| Oblonggotic intracellular parasite | must lie inside host cell, cell will be a brain cell |
| Why is Ricksettia Rickittii atypical | The cell will be a brain cell. |
| Ricksettia Rickittii treatment | Treat with IV antibotics, prognosis is better if caught early. Onset of bacteria is 72 hours, in 14 days a rash will appear. |
| Chlamydia trachomatis | STD Chlamydia, Gram negative rod, causes blindness |
| Chlamydia trachomatis treatment | Treat with Dioicycline, onset of infection is 24-48 hours with clear discharge |
| Chlamydia trachomatis causes of blindness | Oblonggotic intracellular parasite, totatlly dependent on host cell, does not divide by inary fusion |
| Elementary body | smaller and infects the body |
| Reticulate body | smaller body transforms into this, and this is responsible for cellular division. |
| Fungi | Dermatophytoses, no choloraphyl and is a eukaryotic cell. |
| Fungus | is a Thallus plant devoid of chloraphyl, no roots, no stems, no leaves |
| Examples of fungi | Mushroom, yeast, mold |
| Mushroom | Is perfect, produce sexually, medically used as a hallucangentic |
| Yeast | Imperfect, no sexual means of repoduction, so it is asexual reproductions |
| Mold | Imperfect qualities, hyphae and mycelium |
| Hyphae | long hais that grow on food |
| mycelium | large gathering of hyphae |
| Types of asexual reproduction | Spores-Arthrospores, sporoangiospore, chyamydiospore, conidiospore, and blastospore |
| Arthrospores | break at joint, fungal spore formed by the breaing and fragmentation of hypae |
| Sporangiospore | a spore produced inside a closed structure, potato going bad |
| Chlyamydiospore | structure for the preservation of genetic material during adverse times. Has thick wall...... |
| Conidiospore | born unprotected, green color comes from pigmentation, ex. bread mold |
| Blastospore | produced by budding spores, ex. yeast |
| Protozoa | A group of single celled eudaryotic organisms with NO CELL WALL. Animal-no cell wall and plants-cell wall |
| Protozoa classified by | means of motility |
| Protozoa means of motility | Ameoba-sarcodina, flagelates-mastogophora, ciliztes-ciliata, non motile-sporozoa |
| Protozoa forms | Trophoziote, cyst |
| Protozoa cyst | has no motility, no pseudopods with thick cell wall |
| Helminth Parasite | Nematode-is sexual, trematode-has both sexes, cestode-has both sexes |
| Nematode | Differs in size and is sexual, round worms (elongated). As small as microscopic in blood or large as earthworms, is sexual-either male (shorter) or female (longest) |
| Trematode | Fluke, organ specific, is a hermaphrodite-has both sexes (single worms becomes mulit worm infestation), motility-falling leaf movement, attachments-lateral sucker and dorsal sucker, get from contaminated food or water |
| Cestode | segmented worm, each proglottid contains both male and female sex, this is an egg productin machine, ex tape worm. |
| Viruses | Either RNA or DNA, NEVER BOTH |
| Virion | Simplest infectious particle, consisting of an outer portein shell called a capsid and an inner core of nucleic acid (either RNA OR DNA) |
| Virion shape | Rod-shaped |
| Transcription | making RNA out of DNA |
| lysogeny | occurs in bacterial viruses |
| Prion | Infectious protein particle, ex. mad cow disease |
