| [ovine enzootic abortion: seroprevalence in switzerland using a competitive enzyme-linked immunosorbent assay (celisa)]. | the present study gives an overview over the seroprevalence of ovine enzootic abortion in switzerland. 639 sheep flocks out of eight cantons in switzerland were examined by a competitive enzyme linked immunosorbent assay (celisa) for antibodies against chlamydophila abortus (chlamydia psittaci serotype 1), the agent causing ovine enzootic abortion. the eight cantons included aargau, bern, zürich, appenzell-ausserrhoden, appenzell-innerrhoden and fribourg, the vallais and the graubünden. they wer ... | 2002 | 12677686 |
| seroprevalences for ovine enzootic abortion in switzerland. | our 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) analysis was applied to define the cut-off of the pool approach. at a cut-off value of 30% inhibition, the flock-level pooled sensitivity and specificit ... | 2004 | 15488271 |
