Abstract

In a retrospective study, covering the period from 1986 to 1995, tissues of aborted fetuses were re-examined. A total of 347 cases were tested immunohistochemically, among them samples of 223 brains were examined for Neospora caninum, Toxoplasma gondii and Bovine Virus Diarrhoea Virus (BVDV), and 249 placentae for Chlamydiaceae. Two real-time PCR assays, one for N. caninum, and one for T. gondii, were developed. These potential abortion-inducing agents were detected – and confirmed by PCR, except for BVDV – in 16.1% (N. caninum), 0% (T. gondii), 9.9% (BVDV) and 0.8% (Chlamydiales) of the cases examined. Immunohistochemistry proved to be inadequate for the detection of the protozoal epitopes, whereas it was confirmed as a very useful tool for the detection of BVDV. In abortion material, PCR is considered to be more suitable for the detection of protozoa and Chlamydophila abortus, an adequate sampling presupposed.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
