Gram (+)->B. Non-endospore-forming->2.Cells R cocci* a. Lack cytochrome system (e) Streptococcus
Gram (+)->B. Non-endospore-forming->2.Cells R cocci*b. Use aerobicrespiration (f) Staphylococcus
II. Gram (-)-> A. Cells are helical or curved->1. Axial filament(g) Treponema
II. Gram (-) ->A. Cells are helical or curved->2. No axial filament(h) Spirillum
II. Gram (-) ->B. Cells are rods--------------->1.Aerobic,nonfermenting(i) Pseudomonas
II. Gram (-) ->B. Cells are rods--------------->2. Faculatively anaerobic(j) Escherichia
III. Lack of cell walls(k) Mycoplasma
IV. Obligate intracellular parasites->A. Transmitted by ticks(l) Rickettsia
IV. Obligate intracellular parasites->B. Reticulate bodies in host cells(m) Chlamydia
C/C Cyanobacteria & algae ---------------------------> Both are oxygenic photoautotrophs. Cyanobacteria=prokaryotes;algae=eukaryotes
C/C Actinomycetes&fungi ----> Both R chemoheterotrophs can form mycelia;some form conida; Actinomycetes=prokaryotes; fungi=eukaryotes
C/C Bacillus & Lactobacillus--->Both R large rodshaped bacteria;Bacillus formsendospores, Lactobacillus=fermantative non-endospore-forming rod
Pseudomonas&Escherichia->Both=small rod shaped bacteria. Psudomonasoxidative metabolism; Escherichia=fermantitive;Pseudomonas=polar flagella;Escherichia=peritichous flagella
Leptospira & SPirllum->Both=helical bacteria; Leptospira=(spirochete) has anaxial flilament. Spirllum has flagella
Escherichia & Bacteroides->Both are gram(-), rodshaped bacteria. Escherichia=faculatitive anaerobes, and Bacteroides=anaerobes
Rickettisia & Chalmydia->Both=obligatory intracellular parasites. Rickettsia=transmitted via ticks; Chlyamydia=unique development cycle
Ureaplasma & Mycoplasma->Both lack peptiglyocan cell walls. Ureaplasmaare archaea; Mycoplasma=bacteria
Gram-stained bacteria that live in human intestine, U would expect to find mostly= Gram (-) Rods
Which following does NOT belong with others?Lactobacillaes
Pathogenic bacteria can be=all of the aboveMotile/RodS/Cocci/Anaerobic
Which of the following is an intracellular parasite?Ricketssia
Which of the following terms is the most specific?Bacillus
Which of the following does not belown w/ the others?Staphylococcus
Which of the follwing pairs is mismatched?spirochete-Helicobacter
Spirillum is not classified as a spirochete b/c spirochetesPossess axial filaments
When Legionella newly discovered, why classified w/ pseudomonads?It is an aerobic gram-negative rod
Unlike purple & green phototrophicbacteria, cyanobacteriaproduce oxygen during photosynthesis
