Elementary body envelopes from Chlamydia psittaci can induce immediate cytotoxicity in resident mouse macrophages and L-cells.
Isolated, purified Chlamydia psittaci elementary body envelopes at a high multiplicity of infection (1,000:1) are capable of inducing immediate cytotoxicity in resident mouse macrophages and 929 L-cells.
متن کاملProtein antigens of Chlamydia psittaci present in infected cells but not detected in the infectious elementary body.
Ocular infection of guinea pigs with the guinea pig inclusion conjunctivitis (GPIC) strain of Chlamydia psittaci produces a clinical condition representative of acute chlamydial conjunctivitis in humans. Guinea pigs which had recovered from two challenges with GPIC were used as a source of sera for the identification of antigens present in GPIC-infected tissue culture cells but absent in the in...
متن کاملRequirements for ingestion of Chlamydia psittaci by mouse fibroblasts (L cells).
Ingestion of 14C-amino acid-labeled Chlamydia psittaci (6BC) by mouse fibroblasts (L cells) was inhibited when the host cells were incubated for 30 min at 37 degrees C in Earle salts containing 10 mug of crystalline trypsin per ml. Tryptic digestion also inhibited the ingestion of 1-mum polystrene latex beads. Trypsin-treated L cells almost completely recovered their ability to ingest chlamydia...
متن کاملEchocardiographic follow-up of Chlamydia psittaci myocarditis.
Chlamydia psittaci myocarditis has been infrequently reported. A case of serologically confirmed C psittaci myocarditis with dilated left ventricle and severely impaired left ventricular function is described. Serial echocardiograms demonstrated complete recovery after therapy. An early diagnosis has important prognostic implications.
متن کاملDetection of Chlamydia psittaci by immunofluorescence.
A direct fluorescent-antibody (FA) test was developed to detect Chlamydia psittaci in dural impressions from specimen-inoculated mice. Technical procedures for the test were compared. C. psittaci was found in mice after infection as early by the FA technique as it was by cytochemical staining methods usually used. The lymphogranuloma venereum organism was also stained by conjugated antibody to ...
