First report of naturally acquired clinical sarcocystosis in a pig breeding stock

Detection of Zoonotic Protozoa Toxoplasma gondii and Sarcocystis suihominis in Wild Boars from Spain

“…Sarcocystis miescheriana is an ubiquitous parasite; recently, Calero‐Bernal et al. () reported the presence of only S. miescheriana among 44 isolates studied from 11 US states, and it has been confirmed molecularly in China (Yan et al., ), Iran (Kia et al., ) and Switzerland (Caspari et al., ). Sequence analysis and phylogenetic results showed that genetic variability of S. miescheriana is very low; our sequences were found to correspond almost perfectly to either isolates from wild boars in Iran (GU395554) or Lithuania (JN26523).…”

Vorkommen der interstitiellen Nephritis bei Schweinen

“…In addition, granulomatous nephritis due to parasitic infestation or specific bacterial infection can occur (22,34). In some cases interstitial nephritis may be caused by Sarcocystis mischeriana or Trypanosoma (3,7).…”

“…Incidentally observed interstitial nephritis represents a wellknown lesion (17). It represents a worldwide occurring phenomenon which affects boars, sows and piglets (7,12,14,15,20). In the study of de Vries (9), which was carried out in Switzerland, interstitial nephritis with an occurrence rate of 14 % was the most commonly observed organ alteration during their investigation of pigs from a slaughterhouse.…”

“…Although interstitial nephritis is frequently encountered in pigs, its relevance, aetiology and pathogenesis remains undetermined (11,28,33). This might be due to its lacking clinical relevance because in most cited cases no clinical signs were associated with the occurrence of interstitial changes in the kidneys (7,8).…”

Molecular diagnostics of Sarcocystis spp. infections

“…Acute sarcocystiosis in animal intermediate hosts is characterized by encephalitis, inflammation of the brain and spinal cord, bleeding diathesis. It may cause fetal death, premature delivery, abortions in pregnant animals (Tenter 1995, Caspari et al 2010. Mild and chronic sarcocystiosis leads to a decrease in body weight and amount of fur (Tenter 1995).…”
