Only 1 of the paromonycin treated patients developed a mediastinitis infection due to one of the treated microorganisms.
Subsequently, the treated microorganisms are re-suspended, adequately diluted, and streaked out on agar plates to yield single colonies.
After sterilization, each test tube was inoculated with 100 µl of one of the previously prepared bacterial suspensions and then incubated under moderate shaking of 100 rpm at 35 °C for 24 h (treated microorganisms).
Controlled hyperthermia to treat microorganisms and cancers is receiving renewed attention [ 19].
In contrast to other resistant or difficult to treat microorganisms, MRSA carriage can be eliminated through the application of decolonization agents, such as nasal mupirocin and chlorexhidine soap.
These contradictory results are probably ascribable to differences in patients and pathogens responsible for pneumonia; since in the studies those found higher mortality rates when AB was inadequate, the patients who received inadequate AB were the ones with pneumonia caused by the most difficult to treat microorganisms [ 5, 11].
In that work, differently morphological silver particles such as spherical, rod-shaped and truncated triangular silver nanoparticles were used to treat microorganism.
Difficult-to-treat microorganisms and strict anaerobic bacteria were more frequently isolated from patients without an early response compared to those with.
Whether surveillance cultures could further improve empirical treatment selection for ICU patients with suspected hospital-acquired pneumonia (HAP) is still debated but certainly should be weighed when difficult-to-treat microorganisms abound, making initial choices particularly risky [ 52, 53].
Based on those data, most patients' therapy could be safely switched to monotherapy after 3 to 5 days, provided that the initial therapy was appropriate, the clinical course evolved favorably, and microbiological data did not indicate difficult-to-treat microorganisms, with high in vitro MICs, as can be observed for some non-fermenting GNB.
