- Hookworm = blood sucker = chronic blood loss
A d= sucks blood 0.2 ml/worm/day
chronic hemorrhage from punctures site - release of anti-coagulant from esophageal glands - Bleeding from multiple site due to migration
550
Why dimorphic anemia by A d??
deficiency of Fe + Folic acid / V-B12
550
Skin manifestation by A d ??
Ground itch
/
ancylostome dermatitis
why A d more pathogenic than n americans ??
- more bleeding
- A d = 6 tooth
N a = 4 tooth - N a = 0.03ml/worm/day
- A d = more migdratory = more bleeding
