IV-B: Prokaryotes Flashcards
(178 cards)
categorizes bacteria into taxa based on rRNA sequences
Bergey’s Manual
Greek god who could assume many shapes
Proteus
the largest group of bacteria, most gram-negative and chemoheterotrophic
Proteobacteria
five classes of proteobacteria
alphaproteobacteria, betaproteobacteria, gammaproteobacteria, deltaproteobacteria, epsilonproteobacteria
capable of growth with very low levels of nutrients, nitrogen-fixing bacteria, chemoautotrophs, and chemoheterotrophs
Alphaproteobacteria
most abundant in the oceans on the basis of weight
Pelagibacter
member of a group of SAR 11 (Sargasso Sea)
Pelagibacter ubique
grow in soil, using nutrients excreted by plants and fix nitrogen
Azospirillum
industrially important aerobic organisms that convert ethanol into acetic acid
Acetobacter & Gluconobacter
emerging pathogen found in patients with chronic granulomatous disease
Granulibacter
Transmitted to humans by insect and tick bites, gram-negative rod-shaped bacteria or coccobacilli
Rickettsia
Epidemic typhus
Rickettsia prowazekii
Endemic murine typhus
Rickettsia typhi
Rocky Mountain Spotted Fever
Rickettsia rickettsii
live obligately within white blood cells, rickettsia-like bacteria
Ehrlichia
they have prosthecae because of the constant changing flow of water
Caulobacter
budding bacteria found in lakes, found growing in laboratory water baths
hyphomicrobium
infects the roots of leguminous plants, such as bean, peas, or clover
Rhizobium & Bradyrhizobium
insert a plasmid into plant cells, inducing a tumor-like gall, and used in genetic engineering
Agrobacterium
appear swollen and red with round, raised lesions and can have pus
Bartonella
cat-scratch disease, mild infection can occur at the site of the scratch or bite
Bartonella henselae
small non-motile coccobacilli & obligate parasites of mammals and have the ability to survive phagocytosis
Brucella
important element of the body’s defense against bacteria
phagocytosis
oxidize nitrogen for energy and fix CO2
chemoautotrophic
