Diagnosis of quinolone-resistant Coxiella burnetii strains by PCR-RFLP.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A total of 12 strains of Coxiella burnetii (8 Greek isolates from acute Q-fever patients, two reference strains-Nine Mile and Q212-and two pefloxacin-resistant laboratory strains) were examined for the presence of point mutations in the quinolone resistance determining region (QRDR) of gyrA gene by direct DNA sequencing of the polymerase chain reaction (PCR)-amplified fragments. The gene sequences of all eight Greek isolates and the two reference strains Nine Mile and Q212 [minimal inhibitory concentration (MIC)</= 4 microg/ml] were identical. Direct DNA sequencing of the in vitro-selected resistant strains (MICs to pefloxacin, 8-32 microg/ml) revealed a transition (G-->A) at the corresponding codon 87 of E. coli. This mutation lead to the substitution of Glu (codon GAG) by Lys (codon AAG ). Restriction maps of amplified gyrA gene sequences were determined by GCG Wisconsin PACKAGE, and the MnlI restriction enzyme was found to cut only the sensitive strains sequences and not the resistant ones. The present PCR-RFLP analysis has proved to be a simple, rapid, and useful method for the detection of Coxiella burnetii and, at the same time, for the diagnosis of quinolone-resistant Coxiella burnetii strains.
