| isolation of circovirus from lesions of pigs with postweaning multisystemic wasting syndrome. | postweaning multisystemic wasting syndrome (pmws), an apparently new disease, has been recognized in swine herds in western canada. young pigs with this disease have progressive weight loss, tachypnea, dyspnea, and jaundice, accompanied by interstitial pneumonia, lymphadenopathy, hepatitis, and nephritis. we examined more than 400 pigs from more than 70 herds in alberta, saskatchewan, and manitoba with cases of pmws. a small virus was isolated from a range of tissues from 8 of 8 affected pigs ex ... | 1998 | 9442952 |
| postweaning mortality in manitoba swine. | a case-control study to investigate the contribution of postweaning multisystemic wasting syndrome (pmws) and porcine circovirus type 2 (pcv-2) to deaths among piglets of nursery age (19 to 68 d) in manitoba indicated a significant positive association between pcv-2 infection and an increased mortality rate in nursery pigs. the clinical syndrome pmws was seldom recognized in case or control herds; however, pcv-2 infection was widespread at the herd level. other factors more strongly associated w ... | 2006 | 16850937 |
| porcine teschovirus polioencephalomyelitis in western canada. | beginning in 2002, a small number of pig farms in western canada began reporting 4-7-week-old pigs with bilateral hind-end paresis or paralysis. low numbers of pigs were affected, some died, most had to be euthanized, and those that survived had reduced weight gains and neurological deficits. necropsies revealed no gross lesions, but microscopic lesions consisted of a nonsuppurative polioencephalomyelitis, most severe in the brain stem and spinal cord. the lesions were most consistent with a vir ... | 2011 | 21398466 |
| study of animal-borne infections in the mucosas of patients with inflammatory bowel disease and population-based controls. | crohn's disease may be triggered by an infection, and it is plausible to consider that such an infection may be animal borne and ingested with our food. there has been considerable interest in the past in determining whether mycobacterium avium subsp. paratuberculosis (m. avium) might be the etiologic agent in crohn's disease since it causes a disease in cattle that is similar to crohn's disease in humans. we aimed to determine if there was an association between crohn's disease and infection wi ... | 2003 | 14605128 |
