Document Summary
Pseudomonas aeruginosa - harmful when ingested (pathogen); e ects more detrimental for immune-compromised indv; found at hospitals: mrsa (hospital superbug) - mobile phones carry this. Listeria - hard to defend o ; causes septic shock identify pathogen and treat: microbial therapies. Archaea dna sequence more similar to eukaryotes than bacteria. Bacteria: share nucleotide changes (bases); form a group; single celled biochem of bacteria more related to eukaryotes (not dna) Archaea: found in very harsh environments; have similar base changes (di erent from bacteria); di evolutionary group: microbes from a mixed culture not pure. Evolutionary tree by dna sequence: if it"s more alike with dna = closer evolutionary relatedness. Prokaryotes: cell w out membrane bound organelles; no true nucleus: mitochondria: have its own dna - endosymbiotic. Microbes: can form colony that is distinctive and can be rst stage to identify pathogen.
