Eubacteria Archaebacteria
cell walls that contain peptidoglycan cell walls that contain proteins or polysacc
Cytoplasmic membrane made of phospholipids Cytoplasmic membrane made of long fatty
Gram positive and gram negative bacteria (phytanol)
o G- Spirochetes, aerobic rods and cocci, Can be found in harsh environments and p
anaerobes, rickettsias and chlamydias, budding or stuff like methane
appendaged bacteria (mycoplasma also but no cell o Examples: methane producers, red
wall) halophiles, sulfur dependent bacteria,
o G+ cocci, endospore formers, rods, thermoplasmas
mycobacteria, actinomycetes
Eubacteria Archaebacteria
Cell Walls Peptidoglycan Proteins, polysaccharides
Cytoplasmic membrane Phospholipids Phytanol (long FA chains)
Protein Synthesis differs
Living Environments common Harsh- heat/salt
Other G+
G-
Mycoplasms (no cell wall)
Gram Positive & Gram Negative
Important to consider structure when treating patient with antibiotics

, Aerobic Rods (Bacilli) and Can be found in soils and water; e.g., Pseudomonas
Diplococcus Neisseria
Cocci Neisseria gonorrhoeae- gonorrhea
Neisseria meningitides-meningitis
Facultative G- Rods Can grow with or without oxygen, can be curved or straight
Salmonella- cause bad infections
Enterobacteria; can be natural to flora but cause infection in different part of
Escherichia, proteus, klebsiella, serratia
can cause typhoid fever and gastroenteritis
Shigella- causes dysentery
Yersinia pestis causes plague
Facultative anaerobes- vibrio cholera; cause cholera and Haemophilius influe
is the leading cause of bacterial meningitis in children
Obligate Intracellular Cannot grow on their own; require a host like viruses
Must be cultivated in tissue culture
parasites Rickettsia- can be caught from flea or tick bite
Chlamydia- cause blindness, & pelvic inflammatory disease, sterility in women
G- Anaerobic Bacteria Predominant organisms in human instestine, but cause infections in othe
body
1. Require sulfur
commonly found in wound infections; can be found in
intestinal tract
Bacteroides fragilis- most common cause of wound in
gives off smell
2. Do not require sulfur
Spiral shape Highly coiled
May have flagella that enable motility
Best seen with wet mount or darkfield
Gram Positive Eubacteria
Cocci Appear based in irregular clusters, pairs, or groups of four
Irregular clusters- micrococcus, harmless, live in freshwater
Clusters or chains- staph aureus (TSS), can live on skin and mucou
animals
Groups of four- Deinococcus, red pigmented, can resist high level
in extremely cold environments
Streptococcus pyogenes- most common, causes strep throat, scar
fever
Streptococcus pneumoniae- bacterial pneumonia
Streptococcus lactis- milk and dairy products starter culture for m
Regularly Shaped Rods Cannot form spores
Have uniform appearance
Lactobacillus- used to produce yogurt and cheese
Endospore forming In dire conditions, bacteria form a hard shell of protection
