“…The losses incurred by PTb in Iran are estimated to be approximately several thousand Euros per year for an HF farm with 200 cows (Taghipour Bazargani et al, 2007), and this is consistent with losses estimated elsewhere (Lee et al, 2006). Kasravi and Nowrouzian showed HF cattle with clinical PTb in Iran are more likely to be culled because of having a left-displaced abomasum (LDA) than symptom-free cattle (Kasravi and Nowrouzian, 2004). This imposes an extra cost to farmers.…”

Paratuberculosis is an important disease of ruminants with a worldwide distribution. In developing countries where funding constraints challenge establishment of control schemes, large losses are incurred on cattle farmers due to paratuberculosis. In this study, faecal specimens from Holstein-Friesian cows with progressed and moderate clinical paratuberculosis (N = 223) from 13 dairy farms in Isfahan, Central Iran, were subjected to bacterial culture. Culture growth diagnostic for M. avium subsp. paratuberculosis was found in cattle from nine of the 13 farms and in 71 of the cattle studied. These results illustrate the emergence of PTb in this region, and they imply that PTb should be given a higher priority for veterinary measures.
