BIOL 3200 Lecture Notes - Lecture 16: Helicobacter Pylori, Pertussis, Escherichia
Document Summary
Autoinomycin: binds to dna, blocks transcription (dna >rna) Myxopyronin > myococcous fuluis, rna polymerase before polymerization. Inplace of rifambin because of resistance issues. Viable/ non- cultivable organisms are still out in the wild that haven"t been discovered. Number of genes and dna (woese) molecular phylogenetics viable, non- culturable (you can get sequences rather than growing them) These can be pathogens to humans (ex. heliobacter pylori- involved with ulcers, in epsilon; vibrio cholera, comma shaped; neissara gonnoreah caused by dipliococcous,; escheria coli, normal ora or virus depends on the strain) Beta group: bordatella pertusis (causes whooping cough) Gamma group: desufforibrio sulfer cycle; psuedonomas aerginosa (burns, lung infection associated with cystic brosis; end up with ammonia like symptoms) Purple sulfer bacteria and non-sulfer bacteria which are capable of photosynthesis. Endosymbiotic relationships: some can be good at this; mostly alpha group bacteria; rna sequence. Most are chemoautotrophs some are heterotrophs, a number of them are photosynthetic.
