Hookworm
* Most hookworms burrow into intestines
  - small intestines
* Most hookworms cause infection
  - intestinal infection
* Most hookworms enter juvenile stages
  - skin
  - feed on blood
* Most hookworms have big appetite
  - structures
* Most hookworms infect dogs
* Most hookworms invade intestines
  - mouse intestines
* Most hookworms live in intestines
  - use mouthparts
* Some hookworms cause anemia
  - death
  - diarrhea
  - illnesses
  - severe illnesses
  - weakness
  - get nutrition
* Some hookworms have natural secretion
  - symptoms
  - infect cats
  - live for years
  - move through bloodstreams
  - parasitize humans
  - penetrate skin
  - suck blood
* actually attach themselves to the dog s intestinal wall.
* also have a very different digestive track.
* appear to evade or inhibit effective human immune responses.
* are a major world parasite, infecting nearly a billion people
  - serious threat to dogs, especially young puppies
* are a type of parasitic roundworms
  - roundworm parasite that invade the body and live in the small intestine
  - also parasites
  - another roundworm and one of the most common helminth infections worldwide
* are blood feeders and the mouthparts of hookworms have teeth
  - sucking parasites that live in the small intestine
  - common parasites of dogs regardless of age
  - long, skinny worms that are unsegmented
  - long-lived and are capable of living as long as the cat
  - monoxenous, as their life cycle depends on only one host
* are more common in warm, moist environments
  - severe and can cause a weak kitten to die
  - most common in the subtropics and are uncommon in the United States
* are one of the most destructive parasites
  - harmful intestinal parasite of dogs
  - second only to malaria as parasitic causes of human misery and debility
  - small worms measuring one cm
* are smaller than roundworms and reside in the small intestine
  - spread by eating infected larvae that are in the environment
  - the most common parasite
  - transmiited to humans via contact with contaminated soil
  - unique in their ability to penetrate human skin
  - vigorous blood suckers due to which they can affect the inner lining of the stomach
* attach themselves onto the intestinal lining with hook-like teeth.
  - the intestinal lining and cause a great deal of damage and blood loss
* can be fatal to puppies
  - fatal, especially in puppies
  - present in household pets, including dogs and cats
  - bore through intact skin
* can cause a skin disease in humans called cutaneous larval migrans
  - blood loss, weight loss, diarrhea or death, especially in young cats
  - itchy skin lesions and abdominal problems
  - enter the body by penetrating the skin of the feet
* causes anaemia, and so, it needs great attention
  - anemia in the small sea creatures, and they eventually starve
* enter the body through skin, commonly through bare feet
  - human body through skin from infected water
* grab onto the intestinal mucosa, resulting in hemorrhage of the mucosa and loss of blood.
* grip the intestinal wall and suck blood.
* hatch in damp vegetation.
* have a complex life cycle that begins and ends in the small intestine
  - direct life cycle and huge loads can build up in the system in a very short time
  - pretty sharp teeth and cause the dog's intestine to bleed
  - such teeth
* includes brains
  - cell membranes
  - cells
  - corpi
  - cytoplasm
  - faces
  - heads
  - nuclei
  - plasma membranes
  - sections
  - skulls
  - vacuoles
* infect about one billion people, mostly in developing countries
* is an intestinal parasite of humans that usually causes mild diarrhea or cramps
  - especially prevalent in the south and southeastern United States
  - one of the most prevalent infections in humans
  - the most common temperate-zone parasite that can penetrate unbroken skin
* live in the human intestine drinking the blood it sucks from the intestine wall
  - intestine of infected humans
* parasite that is behind millions of infections worldwide
  - lives in the gut and causes anemia
* present a far more serious threat to both the mother and puppies
  - slight risk to humans if larvae in the soil contact skin
* require a moist, fairly cool environment to survive and develop as free-living organisms.
* suck blood and therefore cause internal blood loss.
* tend to be medication resistant and reinfection occurs at a high rate
  - live in tropical and subtropical locations and do best in moist, hot climates
* thrive best in a moist, sandy environment.
