Journal ArticleDOI
Recent developments in the laboratory diagnosis of chlamydial infections.
Konrad Sachse,Evangelia Vretou,Morag Livingstone,Nicole Borel,Andreas Pospischil,David Longbottom +5 more
TL;DR: An overview on methodologies and technologies used currently in diagnosis of chlamydial infections with emphasis on recently developed tests is given, and a combination of a specific real-time PCR assay and a microarray test for chlamydiae is proposed as an alternative reference standard to isolation by cell culture.
Journal ArticleDOI
Multi locus sequence typing of Chlamydia reveals an association between Chlamydia psittaci genotypes and host species.
Yvonne Pannekoek,Veerle Dickx,Delphine Sylvie Anne Beeckman,Keith A. Jolley,Wendy Keijzers,Evangelia Vretou,Martin C. J. Maiden,Daisy Vanrompay,Arie van der Ende +8 more
TL;DR: The population structure of Chlamydia was assesed using multi-locus sequence typing to report for the first time an association between C. psittaci genotypes with host species and host species jumps.
Journal ArticleDOI
Seroprevalences for ovine enzootic abortion in Switzerland
TL;DR: The cELISA in combination with testing pooled sera and statistical methods for true prevalence estimation provided a good survey tool at lower costs and time when compared to other approaches.
Journal ArticleDOI
Serological Diagnosis of Ovine Enzootic Abortion by Enzyme-Linked Immunosorbent Assay with a Recombinant Protein Fragment of the Polymorphic Outer Membrane Protein POMP90 of Chlamydophila abortus
David Longbottom,Susan Fairley,Stephanie Chapman,Evgenia Psarrou,Evangelia Vretou,Morag Livingstone +5 more
TL;DR: A series of overlapping recombinant antigens representing the polymorphic outer membrane protein POMP90 of C. abortus was assessed by enzyme-linked immunosorbent assay (ELISA) and the new rOMP 90-4 ELISA was found to be a more sensitive and specific test than CFT for differentiating animals infected with C. abortedus from those infected withC.
Journal Article
Diagnosis of ovine enzootic abortion, using a competitive ELISA based on monoclonal antibodies against variable segments 1 and 2 of the major outer membrane protein of Chlamydia psittaci serotype 1.
V. Salti-Montesanto,E. Tsoli,P. Papavassiliou,E. Psarrou,Bryan Markey,G.E. Jones,Evangelia Vretou +6 more
TL;DR: The new cELISA is a sensitive and specific assay for antibodies against C psittaci abortion strains that is rapid and easy to perform and does not require serum dilutions and is suitable as a routine test for chlamydial diagnosis and seroepidemiologic studies.
