Introduction
Cysticercosis is a type of tapeworm that can be
found in uncooked pork. When infected into a
human it can reach many places including our
brain. When it reaches the brain it can be very
deadly. So next time youre about to eat that
pork chop make sure to check how well cooked it
is because you could become very sick.

Descriptions

• A parasitic infection (common to
  cottontail rabbits and snowshoe hares.) They
  appear as sacs of clear fluid containing small
  white objects.

  370_12150_12220-26630--,00.html

• Rare tapeworm infection from pork, caused by
  Taenia solium. Infection occurs when the tape
  worm larvae enters the body and causes cysts.
  When cysticeri are found in the brain, the
  condition is called neurocysticercosis.

Anatomy and Physiology

• Anatomy
• Head/scolex, adhesive organs, intestinal mucosa
• membrane.
• 3 structures
• Diphyllobothrium latum scolex w/ organs
• Taenia saginata 4 muscular suckers
• Taenia solium muscular suckers rostellum w/
  hooks.
• Has multiple hermaphroditic egg units
• Physiology They are hermaphrodites.
  Proglottids(buds) produce and stay attached to
  intestine wall till they mature. The buds break
  loose and are passed through feces.

Life cycle of the worm

• Pigs raised in unsanitary conditions can have
  cysticeribladder worms in muscles
• Capsule that contains scolex
• The bladder worm is ingested. The stomach juice
  dissolves into capsule wall (pork chops.)
• Scolex turns inside out and the hooks and
  suckers attach to intestine wall
• Proglothds (buds) produce. They stay attached
  for awhile and mature. They eventually become
  hermaphrodites.
• The buds break loose and pass through feces.
• Chain reaches 20 ft. and has approx. 1000 buds.
• Each proglottid (bud) has approx. 60,000 eggs.
• Fertilized eggs that are released can reach soil
  and be consumed by pig.

How the worm gets in hosts

• Ingested by immature tapeworms in raw or uncooked
  pork.
• Poor personal hygiene can cause infection.
• Pigs raised in unsanitary conditions can ingest
  bladder worm into their stomach.

Can you prevent it??

• Dont eat raw/uncooked meat
• Wash hands with soapy water before handling food
• Wash and peel veggies and fruit
• Drink mostly bottled or boiled water or
  carbonated drinks

Symptoms of worm infestation

• General- brain swells
• Muscle- none/ lumps under skin
• Eye- blurry vision, disturbed vision, retinal
  swelling, retinal detachment
• Neurocysticercosis- seizures, headaches,
  confusion, lack of attention to people and
  surroundings, swelling of brain, sudden death.
• Eye- causes blindness
• Spinal cord- paralysis

Diagnosis of worm infestation

• MRI and CT brain scans
• Blood tests
• Surgery
• Ask where youve traveled and eating habits

14
Treatment of worm infestation

• Anti-parasitic drugs
• anti-inflammatory drugs
• Eye surgery
• Or no treatment at all if its not that bad

Control of worm infestation

• See health care provider
• Anti-parasitic and anti-inflammatory drugs
• Surgery (in eyes or to reduce brain swelling)

Distribution of worm infestation
Migrate from small intestine to stomach, back to
small intestine. Eggs hatch and larvae penetrates
lining, enters blood stream. Larvae can be
distributed to any organ in the body. They grow
into metacestode stage. If there are few
cysticerci in liver muscles it can go unnoticed
until found by a routine autopsies. www.biosci.ohi

Statistics

• 50 million who have it are in involved with
  agriculture because they come in close contact
  with animals.
• 1 of 6 diseases that could be eradicated ( gone
  entirely)
• 1987-2000 the cysticercosis was reduced from 24
  to 3 in the pig population
• Vaccines are available from Australian scientists
  that can protect pigs and cattle 93- 95 better
