Data were collected from patient charts using a standard form; patients personal information, underlying disease, the name of the antibiotic in use, dosage, usage, duration, reason of antibiotic use (prophylaxis, empyrical, microbiologically prooven infection) and microbiological test results were recorded on the form.
Fig. 3 Microbiological test results.
The type of antibiotic used in the spacer depended on the result of the microbiological test performed previously.
Because the negative result of the microbiological test cannot warrant the absence of pathogen, broad-spectrum antibiotics were empirically delivered.
Microbiological test showed that flufosinateammonium and sodium-glufosinate was be used as a nitrogen source, in the presence of sufficient carbon.
The remaining nine patients, for whom MPCR was the only positive microbiological test, were all receiving recent antibiotic therapy when BAL was performed.
Neuprex, if it works, will be used against toxins released by a family of bugs called gram-negative bacteria (a reference to a microbiological test involving Gram's stain).
Overall, the molecular test displayed a substantially greater sensitivity compared to the microbiological test or radiographic examination, and the results were available within 24 hours, or less, after specimen collection.
Because of this, analyses of blood samples and human fluids must be performed rapidly prior to the administration of broad-spectrum antibiotics, which are eventually adapted to the microbiological test results within the subsequent 48 72 h.
In the microbiological test (pour plate method), use was made of the test bacteria Pseudomonas aeruginosa, while the photochemical test involved the degradation of para-chlorobenzoic acid, monitored by HPLC method.
For early recurrence the following criteria had to be fulfilled: patient considered to be a responder on Day 7, worsening of symptoms in the follow-up period (sum score ≥ 6) and a microbiological test result indicating ≥ 104 colony forming units (CFU/ml).
