Hookworms (picture)

- Ancylostoma tubaeforme and Ancylostoma braziliense

- They are a type of round worm

- Life cycle is very similar to the roundworms we just discussed (picture)

- these guys suck blood and are well equipped to do so) (also show drawing)

- mouthparts have cutting plates

- cause mini hemorrhages and feed on blood

- symptoms include dermatitis, pneumonia, anemia; usually not life threatening, black, tarry feces

- about 1/4 of an inch long

- can produce 10,000-25,000 eggs a day

- takes two days for the hookworm to hatch

- becomes infective in about five days

- can have devestating effects on humans–Cutaneous, dermal larval migrans or creeping eruption–all the same thing–these guys love sandboxes, kitty litter pans, gardens–keep em clean

- As the larvae migrate through the skin and finally die, there is an inflammatory response, and the progress of the larvae through the skin can actually be followed since they leave a tortuous "track" of inflammed tissue just under the surface of the skin. Treatment of such infections requires surgical removal of the migrating larvae. Considering the location of larvae, just under the skin, in light infections this can be done under local anesthesia and is a relatively simple procedure. Infections involving large numbers of larvae can be very uncomfortable, and treatment (removal) might require general anesthesia and supportive treatment with anti-inflammatory drugs.
