detection by immunomagnetic pcr of mycobacterium avium subsp. paratuberculosis in milk from dairy goats in norway.milk samples from 340 individual goats in 34 dairy herds throughout norway were examined for mycobacterium avium subsp. paratuberculosis (m.a. paratuberculosis) by culture and immunomagnetic separation combined with pcr (ims-pcr). the samples included three categories; (a) vaccinated dairy goats in herds with paratuberculosis; (b) vaccinated dairy goats in herds with no history of paratuberculosis; (c) unvaccinated goats in herds with no history of paratuberculosis. viable m.a. paratuberculosis ...200312488077
new probes used for is1245 and is1311 restriction fragment length polymorphism of mycobacterium avium subsp. avium and mycobacterium avium subsp. hominissuis isolates of human and animal origin in norway.mycobacterium avium is an environmental mycobacterium that can be divided into the subspecies avium, hominissuis, paratuberculosis and silvaticum. some m. avium subspecies are opportunistic pathogens for animals and humans. they are ubiquitous in nature and can be isolated from natural sources of water, soil, plants and bedding material. isolates of m. avium originating from humans (n = 37), pigs (n = 51) and wild birds (n = 10) in norway were examined by is1245 and is1311 rflp using new and spe ...200717335590
designing a risk-based surveillance program for mycobacterium avium ssp. paratuberculosis in norwegian dairy herds using multivariate statistical process control analysis.surveillance programs for animal diseases are critical to early disease detection and risk estimation and to documenting a population's disease status at a given time. the aim of this study was to describe a risk-based surveillance program for detecting mycobacterium avium ssp. paratuberculosis (map) infection in norwegian dairy cattle. the included risk factors for detecting map were purchase of cattle, combined cattle and goat farming, and location of the cattle farm in counties containing goa ...201425200769
