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 کاملDetection of Chlamydia pneumoniae and Chlamydia psittaci in sputum samples by PCR.
AIMS To use the polymerase chain reaction (PCR) to detect Chlamydia pneumoniae and Chlamydia psittaci in sputum samples. METHODS A nested PCR was developed, the first stage of which amplified DNA from both C pneumoniae and C psittaci while the second stage targeted specifically at C pneumoniae, allowing the two species to be differentiated. The primers were designed not to amplify sequences f...
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 کاملextremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Use 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...
