Miniature cell formation in Chlamydia psittaci.
In an electron microscope study on the developmental cycle of the goat pneumonitis strain of Chlamydia psittaci in L cells, it was observed that miniature reticulate bodies, measuring approximately 0.2 mum in diameter and surrounded by double unit membranes, were produced infrequently from normal-sized reticulate bodies through a "budding"-like process. As little as 0.1 mug of penicillin per ml...
متن کاملUse of HeLa cell guanine nucleotides by Chlamydia psittaci.
Exogenous guanine was found to be incorporated into the nucleic acids of Chlamydia psittaci when the parasite was grown in HeLa cells containing hypoxanthine guanine phosphoribosyltransferase (EC 2.4.2.8) activity but not when the parasite was grown in transferase-deficient HeLa cells. No evidence for a chlamydia-specific transferase activity was found in either transferase-containing or transf...
متن کاملChlamydia psittaci in birds of prey, Sweden
BACKGROUND Chlamydia psittaci is an intracellular bacterium primarily causing respiratory diseases in birds but may also be transmitted to other animals, including humans. The prevalence of the pathogen in wild birds in Sweden is largely unknown. METHODS DNA was extracted from cloacae swabs and screened for C. psittaci by using a 23S rRNA gene PCR assay. Partial 16S rRNA and ompA gene fragmen...
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 ...
