classification of bacteria cont Flashcards
Growth characterstics include—-?
grows aerobically or not faculatative or not microaerobic or noe incubation temperature PH nutrients required for growth antibiotics resistance
antigen and phage susceptibility classification uses which antigens?
cell wall(o)
flagellar(H)
capsular(k)
What are uses of serotyping?
to determine virulence
to identify pandemic strains
biochemical tests include—?
oxidase nitrate reduction AA degrading enzymes fermentation carbohydrate utilization
the biochemical test used for staphylococci
coagulase test
the biochemical test used for gram positive cocci
pyrrolidonyl arylamidase
what do you call determining the susceptibility pattern of an isolate to a set of specific bacteriophages
Phage typing
O157;H7 E. coli causes?
dysentery(bloody diarrhea) and hemolytic uremic syndrome(kidney failure)
for classification below species level we use–?
serotype, phage type, colicin type, biotype, bioserotype
for classification above species level we use–?
genus(group of species)
family(group of genera)
true or false
genetic similarity should be given priority than phenotype in establishing genera
false
true or false
the primary consideration for genus is that it contains biochemically similar species
true
which nucleotide protein do we use to phylogenetically classify above species? and why?
rRNA
because it has preserved in evolution. in other words it hasnt changed much through time so comparison between genus, family and higher taxonomy levels is easier
species are named according to principles and rules of nomenclature set in the——?
bacteriological code
Prokaryotic cells divide or reproduce by——
binary fission
