Antigen capture ELISA for the heat shock protein (hsp60) of Chlamydia trachomatis.
AIMS To develop an indirect ELISA using the heat shock protein (hsp60) of Chlamydia trachomatis as antigen. METHODS The hsp60 gene was amplified by PCR, expressed in the vector pDEV-107 and transformed into Escherichia coli. The recombinant protein, expressed as a beta-galactosidase fusion product, was captured onto a solid phase using a monoclonal antibody directed against beta-galactosidase...
متن کاملTubal factor infertility is associated with antibodies against Chlamydia trachomatis heat shock protein 60 (HSP60) but not human HSP60.
BACKGROUND Serum antibodies against major outer membrane protein (MOMP) and heat shock protein 60 (HSP60) from Chlamydia trachomatis are correlated with sequelae following infection. Since bacterial and human HSP60 share considerable sequence homology, cross-reactivity to human HSP60 is suggested as being involved in tubal factor infertility (TFI). The aim was to investigate whether antibodies ...
متن کاملReversibility of heat shock in Chlamydia trachomatis.
The heat shock effect on chlamydia development was studied. We report here that the reversibility of the heat shock response did not depend on the stage of chlamydial morphogenesis at which transfer to high temperature occurred, and the infectivity of the particles produced was not affected significantly, so long as the heat shock exposure was not prolonged. Exposure to heat shock for more than...
متن کاملAssociation of antibodies to Chlamydia trachomatis heat-shock protein 60 kD with chronic nongonococcal urethritis.
Ninety male patients with acute nongonococcal urethritis (NGU) who presented for follow-up 10-92 days after initiation of treatment were evaluated. A polymerase chain reaction assay and direct fluorescence antibody test were used to detect Chlamydia trachomatis at presentation and during follow-up. Chlamydial heat-shock protein 60 kD (hsp60) serology with an enzyme-linked immunosorbent assay an...
متن کاملContinuous B-cell epitopes in Chlamydia trachomatis heat shock protein 60.
B-cell peptide epitopes in chlamydial heat shock protein 60 (hsp60) were elucidated with antisera from 13 rabbits immunized with Chlamydia trachomatis serovars B, C, and L2 and antisera from eight women with C. trachomatis-associated ectopic pregnancies. Thirteen major epitopes were identified with the human sera, 10 of which were also observed with rabbit antisera. Seven of the 13 epitopes rec...
