Seroprevalences for ovine enzootic abortion in Switzerland
Preventive Veterinary Medicine, 2004Our aim was to assess the seroprevalence of Chlamydophila (Cd) abortus (Chlamydia psittaci serotype 1), denoted ovine enzootic abortion (OEA), in the Swiss sheep population. A competitive enzyme-linked immunosorbent assay (cELISA) was adapted for the investigation of pooled serum samples (pool approach) and receiver-operator characteristic (ROC ...

Summary The complement fixation test has been used for the diagnosis of enzootic abortion in ewes. Suitable antigens were prepared both from infected yolk sacs of the developing chick embryo and from infected membranes of the sheep. The efficiency of the complement fixation test was assessed by testing blood sera from known infected sheep and from ...

Chromosome Aberrations in Cattle with Chronic Enzootic Haematuria
Journal of Comparative Pathology, 2004Chromosomal aberrations were investigated in 56 cattle with chronic enzootic haematuria (CEH) raised on pastures giving access to bracken fern. Of these animals, 27 were slaughtered and showed neoplastic lesions of the urinary bladder. Tumour tissue from 11 of the 27 cattle contained bovine papillomavirus type 2 (BPV-2) DNA.

THE CONTROL OF BLUETONGUE IN AN ENZOOTIC SITUATION
Australian Veterinary Journal, 1975On account of the wide host range of bluetongue virus and its biological transmission by insects, control of the disease in an enzootic situation is based primarily on the active immunisation of susceptible animals as well as on the prevention of contact between the insect vectors and the susceptible hosts.
