Study Notes

Eukaryotic Cells vs. Prokaryotic Cells

Eukaryotic cells have a true nucleus, while prokaryotic cells do not.
Eukaryotic cells are larger than prokaryotic cells and have membrane-bound organelles.
Prokaryotic cells have a single chromosome, while eukaryotic cells have multiple chromosomes.
Eukaryotic cells have a complex internal structure, while prokaryotic cells have a simpler structure.

Bacterial Infections

UTI is a common bacterial infection, with Escherichia coli being the most common cause.
Bacterial meningitis can be purulent (usually bacterial) or aseptic (usually viral).
Streptococcus agalactiae causes meningitis in neonates.
Streptococcus pneumoniae causes meningitis in adults.
Haemophilus influenzae type B causes meningitis in infants less than 2 years old.
Nesseria meningitidis causes meningitis in adolescents.
Meningitis can be acute or chronic.
Neisseria gonorrhoeae ferments only glucose.
Neisseria meningitidis ferments both glucose and maltose.
Neisseria lactamica ferments glucose, maltose, and lactose.
Neisseria sicca ferments glucose, maltose, sucrose/fructose.
Moraxella catarrhalis does not ferment any of the carbohydrates listed above.
Lyme disease (Lyme borreliosis) is the most common arthropod-borne disease in the United States
Borrelia burgdorferi is the causative agent of Lyme disease

Endemic vs. Epidemic Typhus Fever

Endemic typhus fever (murine typhus fever and fleaborne typhus) is caused by Rickettsia typhi.
Reservoirs for endemic typhus include rodents, such as rats and mice.
Transmission of endemic typhus occurs through infected rat fleas.
Epidemic typhus fever is caused by Rickettsia prowazeki.
Reservoirs for epidemic typhus include infected humans and body lice.
Transmission of epidemic typhus occurs from human to louse to human.
