|
This genus of bacteria grows in chains of spherical cells.
|
Streptococcus
|
|
The __-hemolytic streptococci lyse RBCs
|
Beta
|
|
The __-hemolytic streptococci cause blood-containing media around the colony to turn green.
|
Alpha
|
|
Streptococci acquire energy by what mechanism?
|
fermentation, but most are oxygen-tolerant anaerobes
|
|
B-hemolytic strains of Streptococci are further divided into groups (A through T) based on their cell wall polysaccharides. Which group is the most important in human disease?
|
group A
|
|
This group of streptococcus is responsible for causing "strep throat".
|
group A
|
|
What is the most important pathogenic A-hemolytic streptococcus?
|
S. pneumoniae (bacterial pneumonia)
|
|
This genus of Gram + cocci looks like buckshot or bunches of grapes under the microscope.
|
Staphylococcus
|
|
What are the two main pathogenic species of Staphylococcus?
|
S. aureus and S. saprophyticus
|
|
What mechanism do Staphylococci use to obtain energy?
|
aerobic respiration
|
|
This enzyme, produced by S. aureus, clots plasma.
|
coagulase. Catalyzes the transformation of fibrinogen to fibrin.
|
|
Two major pathogenic species of Neisseria, a Gram - cocci.

|
What is the agent of diphtheria?
|
Corynebacterium diphtheriae, a Gram + rod

|
List three important strict anaerobes belonging to the genus Clostridium, a Gram + spore-forming rod
|
C. botulinum, C. tetani, C. perfringens
|
|
This species of Clostridium is responsible for antibiotic mediated pseudomembranous colitis. The antibiotics typically responsible for this are Clindamycin since it targets anaerobic bacteria, and penicillin family drugs.
