infection with ovine herpesvirus 2 in norwegian herds with a history of previous outbreaks of malignant catarrhal fever.infection with ovine herpesvirus 2 (ovhv-2) in healthy cattle, swine, sheep, and goats was investigated on 43 selected norwegian farms; of which, 41 (95%) had experienced outbreaks of malignant catarrhal fever (mcf) in cattle and/or swine during the preceding 5 years. two of the farms had no history of mcf and were included for control purposes. blood samples from 384 cattle, 40 sows, 75 sheep, and 4 goats were examined for ovhv-2 by polymerase chain reaction assay (pcr) and for antibodies using ...200919286510
quantification of staphylococcus aureus in unpasteurised bovine and caprine milk by real-time pcr.a sensitive and reproducible real-time pcr assay targeting the nuc gene of staphylococcus aureus was applied for quantification of this microorganism in artificially and naturally contaminated raw milk samples. the s. aureus cell equivalents (sces) estimated by the real-time pcr method were two log scales higher than colony forming units (cfus) estimated from a plate count method in artificially contaminated milk. the repeatability of the real-time pcr assay including the dna isolation procedure ...200515862454
genetic diversity of small-ruminant lentiviruses: characterization of norwegian isolates of caprine arthritis encephalitis virus.small-ruminant lentiviruses (srlvs), including caprine arthritis encephalitis virus (caev) in goats and maedi-visna virus (mvv) in sheep, are lentiviruses that, despite overall similarities, show considerable genetic variation in regions of the srlv genome. to gain further knowledge about the genetic diversity and phylogenetic relationships among field isolates of srlvs occurring in geographically distinct areas, the full-length genomic sequence of a caev isolate (caev-1ga) and partial env seque ...200616476978
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
brucellosis in the european union and norway at the turn of the twenty-first century.control and eradication programs of brucellosis in cattle, sheep, goats and pigs have been more or less successfully implemented within the member states (ms) of the european union (eu) and norway after word war ii. as a result, the epidemiological situation of animal brucellosis is extremely diverse among different ms or regions within a ms and among the different animal species. some ms, mainly north european countries, and norway are declared "officially bovine brucellosis free" and/or "offic ...200212414139
chemical composition of milk from a herd of norwegian goats.the chemical composition of norwegian bulk collected goats' milk from the university herd was analysed during one lactation period (30 weeks, 20 samples during 1983). there was considerable variation in chemical composition during the year. fat content decreased over the first 4 months of lactation and increased during the mountain pasture period. protein concentration decreased during the first 4 months, and then increased until the end of lactation. lactose concentration decreased throughout l ...19863755147
