Detection 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 ...
متن کاملPyrimidine metabolism by intracellular Chlamydia psittaci.
Pyrimidine metabolism was studied in the obligate intracellular bacterium Chlamydia psittaci AA Mp in the wild type and a variety of mutant host cell lines with well-defined mutations affecting pyrimidine metabolism. C. psittaci AA Mp cannot synthesize pyrimidines de novo, as assessed by its inability to incorporate aspartic acid into nucleic acid pyrimidines. In addition, the parasite cannot t...
متن کاملProtein-carbohydrate-lipid complex isolated from the cell envelopes of Chlamydia psittaci in alkaline buffer and ethylenediaminetetraacetate.
Exposure of isolated cell envelopes from purified infectious elementary (EB) of Chlamydia psittaci to sodium carbonate-bicarbonate buffer at pH 10 plus ethylenediaminetetraacetate (EDTA) results in partial solubilization of the total protein. The released materials represent 20% of the dry weight, 16% of the total protein, 40% of the total carbohydrate, and 9% of the total lipid of the cell env...
متن کاملInnate immune response in avian macrophages elicited by Chlamydia psittaci Aangeboren immuniteit van aviaire macrofagen geïnduceerd door Chlamydia psittaci
Chlamydia psittaci is a gram-negative, obligate, intracellular bacterium, which mainly infects birds and mammals. Not much is known about innate immunity initiated by C. psittaci. The focus of the present study is on chicken macrophage activation and expression of cytokine, chemokine, caspase-1, iNOS and TLR genes during the early phase and mid-cycle period of the developmental cycle of the hig...
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...
