Noun1.Gram stain- a staining technique used to classify bacteria; bacteria are stained with gentian violet and then treated with Gram's solution; after being decolorized with alcohol and treated with safranine and washed in water, those that retain the gentian violet are Gram-positive and those...
摘要: An historical discussion of the Gram method for staining bacteria is given, showing that the literature abounds in different technics all given this same designation. Nineteen of the most characteristic of these technics were selected for investigation....
Results and Discussion In Vitro Antibacterial Activity We have previously reported the broad spectrum activity of a library of cationic tryptophan rich peptoids against six bacterial strains and compared those activities with the ones of similar antimicrobial peptides12,16. In addition, the hemolytic ...
A total sample size of 200 was estimated to provide a power of 80% with a one-sided alpha level of 2.5% and a non-inferiority margin of 20%, considering 10% non-evaluable patients. DISCUSSION: The GRACE-VAP trial is expected to reveal whether Gram staining can reduce the use of broad...
Results and discussion Portable ozone delivery system An ozone generation and delivery system was designed to enable the topical ozone and antibiotic wound therapy (Fig. 2a). The system features an onboard ozone generation system that uses corona discharge to produce gaseous ozone from ambient air ...
Summaries of the Gram staining results and selected antibiotic agents are shown in eTables 5 and 6 in Supplement 2. Outcomes Per-protocol analysis showed that, at the follow-up or test-of-cure visit, 79 patients (76.7%) in the Gram stain–guided group had a clinical response compared with...
Results One-hundred-fifty-two aerobic samples growing 27 Gram-negatives, 106 Gram-positives, and 19 fungi and 130 anaerobic samples growing 37 Gram-negatives, 91 Gram-positives, and two fungi were analysed. In anaerobic samples, ten discriminators were identified by the random forest method allowi...
3. Results and discussion 3.1. Self-assembly properties of C12−CL5 The molecular weight and purity of the peptides were reconfirmed by electrospray ionization mass spectrometry (ESI-MS) and reversed-phase high performance liquid chromatography (RP-HPLC), respectively (Fig. S1 and S2). The ret...
Results and Discussion Cytological profiling is a powerful tool for high-throughput screening of the mechanism of action of novel antibacterials Bacterial cytological profiling (BCP) relies on the concept that antibacterial compounds with distinct mechanisms of action also produce distinct phenotypes in drug...
Addressing these concerns helps to increase confidence in the reliability and relevance of observed results [13]. There is currently inadequate availability of cumulative antibiogram data for bacterial pathogens to aid specific interventions that will augment AMS implementation and tailor the NSTGs to ...
