BMS 602 Exam #2 Questions and
Answers 100% Solved | Graded A+
LO (11&12): Know the disease states that S. pyogenes and S. pneuomniae
can cause and be able to discriminate between these disease states in a
case study. - ✔✔Streptococcus pyogenes:
-Lance group: A
-Hemolysis: Beta
-Habitat: Throat, and Skin
-Disease: Pharyngitis, Impetigo, Rheumatic fever, Glomerulonephritis
Streptococus pneumoniae:
-Lance group: None
-Hemolysis: Alpha
-Habitat: Throat (primarily nasopharynx)
-Disease: Pneumonia, Meningitis,and Bacteremia
What are some characteristics that allow Streptococci to be distinguished
from other bacteria? - ✔✔Streptococci grow in chains or pairs, and are

catalase-negative organisms. While these are their main distinguishing
traits, Streptococci are also facultative anaerobes, meaning that they can
survive in both aerobic or anaerobic conditions, and have complex
nutritional requirements, meaning that they are not easily grown. (Need
Blood Agar medium or serum enriched media)
What are the three ways that species of Sreptococci are classified? -
✔✔The three different overlapping classification schemes are:
1. Lancefield groupings: serological grouping by surface antigens - groups
are A, B, C, and G.
2. Hemolysis patterns: Complete (beta), partial (alpha), no hemolysis
(gamma)
3. Biochemical properties
*ALL BETA HEMOLYTIC streptococci are put into lancefield groupings,
however other species with different hemolysis patterns are classified by
their biochemical properties.

List the Lancefield grouping, hemolysis pattern, habitat, and common
diseases caused by:
S. pyogenes - ✔✔Lancefield: A
Hemolysis: Beta
Habitat: Throat, skin
Common disease: pharyngitis, impetigo, rheumatic fever (can also cause
necrotizing fasciitis)
List the Lancefield grouping, hemolysis pattern, habitat, and common
diseases caused by:
S. pneumoniae - ✔✔Lancefield: NONE
Hemolysis: Alpha
Habitat: Throat

Common disease: pneumonia, meningitis, bactermia (S. pneumonia is the
leading cause of bacterial meningitis, which is bacterial infection of the
blood)
What is the difference between epithelial and endothelial cells? -
✔✔Epithelial cells are cells that line the hollow organs and glands, and
make up the outer surface of the body. These cells are EXPOSED to the
outside world, and are generally coated in mucous. Some epithelial cells
contain cilia to remove foreign substances.
Endothelial cells are cells that line the INTERIOR surface of blood vessels
and lymphatic vessels. These cells are only exposed to blood or lymph,
NOT the outside world. These cells are not ciliated, and do not contain
mucous.
** Main Differences:
Epithelial: EXTERIOR - ciliated, contain mucous
Endothelial: INTERIOR - non-ciliated, no mucous
What are the roles of the two functional domains of the respiratory system?
- ✔✔The two functional domains are:
