Blood samples from 3112 sheep (185 flocks) and 1196 goats (163 flocks) from the Western region of Austria were tested for pestivirus-specific RNA. In this area, communal Alpine pasturing of sheep, cattle and goats is an important part of farming. The prevalence of sheep persistently-infected (PI) with pestivirus was 0.32% (10 animals) and the PI animals(More)
During the initial phase of operation, the linacs of the Next Linear Collider (NLC) will contain roughly 5000 X-Band accelerator structures that will accelerate beams of electrons and positrons to 250 GeV. These structures will nominally operate at an unloaded gradient of 72 MV/m. As part of the NLC R&D program, several prototype structures have been built(More)
The purpose of this investigation was to determine the influence of communal Alpine pasturing on the spread of pestivirus infections among sheep and goats. The study included 481 sheep from 23 farms and 131 goats from 26 farms pastured on separated Alpine meadows in the western part of Austria. At the starting of pasturing on the sheep meadow, 325 (67.6%)(More)
Faeces of 230 calves with and without diarrhoea collected during the winter period 2004/2005 in 100 Austrian farms (Styria and Lower Austria) were examined for viral, bacterial and parasitic enteropathogens. Torovirus-specific nucleic acid confirmed by reverse transcriptase-polymerase chain reaction was found in 12 of 230 calves (5.2%). Ten of these calves(More)
BACKGROUND Mycobacterium avium subsp. paratuberculosis (MAP) is the etiological agent of paratuberculosis (Johne's disease) in ruminants and is suggested to be one of the etiologic factors in Crohn's disease in humans. Contaminated milk might expose humans to that pathogen. The aim of the present study was to develop a novel real-time PCR assay providing(More)
Paratuberculosis (Johne's disease) is one of the most important diseases in ruminants today. Its contribution is worldwide and the disease is causing severe financial losses among cattle producers in some countries [Hasanova, L., Pavlik, I., 2006. Economic impact of paratuberculosis in dairy cattle herds: a review. Vet. Med.-Czech. 51, 193-211].(More)
Two cases of zinc deficiency in dairy goats from different flocks and not associated with a zinc-deficient diet are described. Hard, dry, hyperkeratotic skin, hair loss and pruritus especially prominent on the back, legs, udder, face and ears were the most common clinical signs. Skin biopsy findings revealed a mixture of orthokeratotic and parakeratotic(More)
An outbreak of tuberculosis due to Mycobacterium bovis occurred in a wild animal park. Three pot-bellied pigs (Sus scrofa vittatus), one red deer (Cervus elaphus), one buffalo (Bison bonasus) and two European lynxes (Lynx lynx) were affected and showed clinical signs including weight loss, enlarged lymph nodes and paralysis of the hindlimbs. Postmortem(More)
Paratuberculosis (Johne's disease) is a chronic infectious disease of ruminants, caused by Mycobacterium avium subspecies paratuberculosis (MAP). Because of its long incubation period, high economic losses, difficulties in diagnosis and possible links to Morbus Crohn in humans, paratuberculosis is one of the most important diseases of ruminants today.
