  Roundworms
Ascariasis is an infection caused by the roundworm Ascaris lumbricoides.

 Common Internal Parasites of Swine
Parasites reside in the stomach and intestinal tract of the pig, causing irritation, impaction, indigestion and lack of appetite.
Whenever a pig dies, your veterinarian should necropsy it to determine parasitic infections by presence of ascarids in the small intestine and by milk spots on the liver surface.
Unfortunately, roundworm and whipworm eggs persist for long periods, kidneyworm and lungworm larvae are found in earthworms, and Strongyloides may be passed in colostrum.

 PIH
Roundworm eggs are remarkably resistant to adverse climate conditions and disinfectants.
Pigs from dewormed sows that have been farrowed on clean slotted or mesh floors and placed in slotted floor nurseries commonly are worm free.
Pigs should be dewormed at 6 to 8 weeks and again 30 days later, or treatment with continuous pyrantel tartrate or Hygromy- cin B can be initiated at weaning.

 Chapter 4: The pig
If infected pigs have been kept out in a field the land should be ploughed and used for a crop, or as grazing for other animals, before pigs are put back on it.
Pigs can be kept in a sty when they will need to be fed twice a day with one feed in the morning and one in the evening.
Pigs can be kept alone or in small groups in a pig sty, a concrete or solid floored pen with a low shelter.

 Controlling Internal Parasites in Swine, G91-1049-A
The pig coughs and forces worms into the throat where they are swallowed and passed into the small intestine--this time to mature and grow to adults.
Pigs have a dry nonproductive cough, loss of appetite and weight, rough hair coat, increased temperature, and an increased rate of respiration accompanied by thumping.
Eggs are laid in the large intestine and pass from the body in manure.

 Broad-Spectrum Control of Worms
The weakened pig can also become more susceptible to bacterial and viral diseases that may be easier to detect than the underlying subtle performance problems generated by the parasites.
Unlike most of the worm parasites of pigs, initial infection with nodular worms does not elicit a strong immune response and populations tend to build up in older animals that are re-exposed.
The weakened pig can have an increased susceptibility to bacterial and viral diseases that may be easier to detect than the underlying subtle performance problems generated by the parasites.

 PIH
During a slaughter check, large numbers of animals can be examined in a relatively short period of time for evidence of disease and parasitism.
It is important to relate the probable cause, extent of the lesions, number of pigs affected and percentage of the lung involved, to average daily gain (days to market), feed efficiency and percent mortality when formulat- ing a plan for drug treatment, feed additives, vaccination, or change in environment.
Pigs with poorer performance may have contracted pneumonia earlier in life or grown so slowly that their lungs may have healed prior to slaughter.

 Raccoon Parasite Seen As Threat To Humans   (Site not responding. Last check: 2007-10-11)
WEST LAFAYETE, Ind. – A roundworm transmitted by raccoons has been responsible for one human death and is a serious threat to cause more fatalities, a Purdue University scientist warns.
Kazakos says that while the raccoon roundworm is known to cause devastating brain and eye damage in such animals as squirrels, rabbits, mice and even monkeys, it only recently was linked to a similar affliction in humans.
He says eggs of the roundworms are carried in raccoon feces and and spread into the soil or onto the grass or other surfaces when the feces break up.

In conjunction with a commercial pig breeder, an assay to measure the ability of pig macrophages to kill Salmonella was developed and tested.
Data suggests that pigs with salmonellosis can be divided into two categories, one group that is unaffected by stress and another group in which stress causes more severe disease and bacterial shedding.

 eMedicine - Ascariasis : Article Excerpt by: David R Haburchak, MD
Usually asymptomatic, infections are most prevalent in tropical and developing countries, where they are perpetuated by contamination of soil by human feces or use of untreated feces as fertilizer.
In developing countries, ascariasis may exist as a zoonotic infection associated with exposure to pigs or pig manure.
Pathophysiology: Ascaris lumbricoides is the largest of the common nematode (roundworm) infections of man. The white or yellow adult is 15-35 cm long and lives 10-24 months in the jejunum and middle ileum of the intestine.

 Monitoring Lesions of Slaughtered Pigs
At one extreme it has been suggested that evaluation of pneumonic lesions in slaughtered pigs can be used to estimate the cost of disease in financial terms and at the other extreme it is suggested that there is no justification for the method.
The probability that a pig will have lesions at slaughter is also determined age of infection, and age at slaughter.
In summary, careful inspection of adequate samples of slaughtered pigs is a relatively inexpensive means of obtaining substantial information about the health status of populations of growing pigs.
