has neutrophils present when smeared

Answer 11

PNEUMOCOCCAL PNEUMONIA (CAP)

Question 12

Gram positive (+) bacteria, cocci

Answer 12

Streptococcus pneumoniae

Question 13

• Virulence Factors for PNEUMOCOCCAL PNEUMONIA (CAP) (4)

Answer 13

Adhesins
Polysaccharide capsule
Phosphorylcholine
Pneumolysin

Question 14

mediates binding of the bacterium to epithelial cells
of the pharynx

Answer 14

Adhesins

Question 15

protects them from lysis by
phagocytes

Answer 15

Polysaccharide capsule

Question 16

• a chemical inserted into cell wall which
  stimulates endocytosis of the bacterium

Answer 16

Phosphorylcholine

Question 17

• a cytotoxin that binds to cholesterol in the
  cytoplasmic membranes of ciliated epithelial cells, producing transmembrane pores that result in the lysis of the cells; it also
  suppresses the digestion of phagocytized bacteria

Answer 17

Pneumolysin

Question 18
