Bacteria/Archaea
| Question | Answer |
|---|---|
| What are some arthropod vestors? | flies, fleas, ticks and misquitos |
| What are the characteristics of Domain:bacteria, Phyllum:Proteobacteria? | Largest taxonomic group, all gram negative bacteria, five classes based on Rna sequencing. |
| What are the five classes based on Rna sequencing of Phyllum: Proteobacteria? | Alpha, Beta, Gamma, Delta, and Epsilon. |
| Fixes nitrogen in the roots of legumes plants? | Azospirillum |
| Rhizobium | fixes nitrogen in nodules of the roots of legume plants |
| Agrobacterium | causes crown gall disease, makes a protein called opines. |
| Agrobacterium tumefaciens | invades plant cells, found in soil, plant gets a wound, then plant gets infected. |
| Ti plasmid with the T-Dna gene | tumors are inserted by the conjugative transfer of a Dna segment |
| Rickettsia | Rocky Mountain spotted fever, or typhus |
| Howard Ricketts and Stanislaus von Prowazek | studied typhus |
| Wolbachia | insects infected with Wolbachia, influence reproduction, kill some insects, protect others, feminize males, promote parthenogensis |
| Wolbachia | infected male, reg female=no offspringreg male, infected female=offspringinfected male, infected female=offspringreg male, reg female=offspring |
| Caulobacter | stalks anchor them to surfaces, found in low nutrient aquatic environments, faculatitive halophile, form buds to reproduce |
| Hyphomicrobium sulfonivorans | reproduce by budding, isolated from tongue and tooth plaque, destroy compounds that cause bad breath |
| Neisseria meningitidis | inflammation of the meninges, meningititis, have nonmotile fimbriae |
| Neisseria gonorrhoeae | causes gonorrhea |
| Thiobacillus | chemoautotrophic- makes its own food from chemicals, |
| Sphaerotilus | chemoheterotophic - must find food souce |
| Psuedomonas aeruginosa | can reside in soap reside, antiseptics, secretes blue water soluble pigment, causes septicemia, meningitis, infections of UTand burns and wounds, spoils food in frige, produces enzymes that digest pesticides, and oil. |
| Moraxella lacunata | conjunctivitis, or pink eye |
| Legionella pneumonphili | cooling towers of air conditioning systems, Legionelloisis, a pheumonia like condition |
| Vibrio | bent rod |
| Vibrio cholerae | causes cholera |
| Enterobacteriales | facultative anaerobes, live in intestines, have fimbriae to adhere to cell surface, produce bacteriocins that cause the lysis of other bacteria, coliforms can break down lactose, used to indicate presence. |
| Enterobacteriales | E.coli, Salmonella,Shigella, Klebsiella, Serratia, Proteus, Enterobacter, |
| E. coli | food poisoning |
| Salmonella | typhoid fever, and food poisoning, Mary Mallon healthy carrier of typhoid. |
| Shigella | causes bacillary dysentery |
| Klebsiella | causes pneumonia, capsulated |
| Serratia | produces a orange-red pigment called prodigiosin, causes urinary, respiratory, wound, and eye infections, at 37 degrees no color, heat sensititive |
| Proteus vulgaris | causes urinary and wound infectionsperitrichous flagela makes them very fast |
| Enterobacter cloacae | urinary tract and respiratory infections |
| Yersinia pestis | pneumonic, septicemic, and bubonic plague |
| Bdellovibrio | lives in the periplasmic space of gram negative bacteria and causes lysis of host bacteria |
| Myxococcus xanthus | lives as a biofilm called a swarm, hunts in wolf packs and leaves a slime trail, fruiting bodies make myxospores |
| Helicobacter pylori | causes stomach ulcers |
| Campylobacter | inflammatory bloody diarrhea or dysentery |
| Cyanobacteria | anabaena - filamentous cyanobacteriaGleocapsa - colonial cyanobacteria |
| Spirochaetes | Borrelia burgdorferi causes lyme disease |
| Treptonema pallidum | causes syphilis, aquired through sexual contact |
| Firmicutes | low G-C ratioGram positive |
| Clostridium tetani | tetanus |
| Clostridum botulinum | tolerates oxygen due to enzyme called sueroxide dimutase, becomes dangerous to humans when infected by virus, produces the neurotoxin botulinum. |
| Clostridum perfringens | causes food poisoning, bacterial agent in gas gangrene |
| Mycoplasma pneumoniae | causes walking pneumonia, resistant to penicillins |
| Staphylococcus aureus | lives 10-46 degrees Celsius, and in extreme pH environments, facultative halophile, produces an enterotoxin, can cause food poisioning, lives on the skin, and mucus membranes |
| MRSA | methicillin resistant Staphylococcus aureus |
| Osteiomylitis | bone infection requires prolonged antibiotic theraphy, or amputation |
| Toxic Shock Syndrom | caused by a bacterial toxin, caused by S. aureus.S.pyogenes can also cause this illness |
| Carbuckles | large, contagious abscesses |
| Furuncles | boils on the skin that are small |
| Strephtococcus pyogenes | can cause white cells to self-destruct, linked to a diverse spectrum of infections and diseases, rheumatic fever, inpetigo, flesh-eating disease,strep throat, scarlet fever |
| Bacillus anthracis | causes anthraz |
| Actinobacteria | high G-C ratiogram positive |
| Gardnerella vaginalis | causes vaginitis |
| Mycobacterium | M.tuberculosis= tuberculosism.leprae= leprosy |
| Domain: Archaea | two phylum: Crenarchaeota and Euryarchaeota |
| Phylum: Crenarchaeota | Sulfolobolus - hyperthermophiles |
| Phylum: Euryarchaeota | Methanobacterium and Halobacterium |
| Methanobacterium | methanogens, live in the gut of humans, aids in the digestion of food |
| Halobacterium | extreme halophiles |
| Thiomargarita namibiensis | the largest bacteria 750 um can be seen with the naked eye, giant cocci |
| Nanobes | nanobacteria, smallest form of life, smalles known bacteria, found on rocks and sediments |
