streptococci

Question 13

how can bactericides fragilis (a normal gut anaerobic commensal) cause an abscess?

Answer 13

Intestinal contents “leak” into peritoneal cavity with normal bacteria

abscess –> facultative anaerobes consume O2 –> B fragilis can replicate

Question 14

urogenital tract normal bacteria

Answer 14

staphylococci

enterics

Question 15

normal microbiota fxn to prod/secrete xs amounts of

Answer 15

vit B12, K

disruption can potentiate warfarin

Question 16

Answer 16

normally degrades digoxin

if disrupted microbiota –> potentiates digoxin

Question 17

Answer 17

aids in estrogen absorption

need backup OCP if on abx
