The Phytochemical Tactics for Battling Antibiotic Resistance in Microbes: Secondary Metabolites and Nano Antibiotics Methods

One of the most serious threats to human health is antibiotic resistance, which has left the world without effective antibiotics. While continuous research and inventions for new antibiotics are going on, especially those with new modes of action, it is unlikely that this alone would be sufficient to win the battle. Furthermore, it is also important to investigate additional approaches. One such strategy for improving the efficacy of existing antibiotics is the discovery of adjuvants. This review has collected data from various studies on the current crisis and approaches for combating multi-drug resistance in microbial pathogens using phytochemicals. In addition, the nano antibiotic approaches, are discussed, highlighting the high potentials of essential oils, alkaloids, phenolic compounds, and nano antibiotics in combating antibiotic resistance.

Antimicrobial Resistance: Physicians' and Pharmacists' Perspective

Aims: The aim of this study was to evaluate pharmacists' and physicians' attitudes and knowledge about antimicrobial treatment and resistance and based on the results to identify possible gaps and suggest opportunities for collaboration between the two professions. Methods: The physician's questionnaire consisted of 47 items and the pharmacists' questionnaire consisted of 50 items. Participants were asked to identify situations in which they were more likely to prescribe/dispense an antimicrobial without a firm indication, to identify the greatest contributors to antimicrobial resistance (AMR) among health care workers, to rate statements related to AMR, how frequently they used different sources of information and to rate the possible causes of AMR. Furthermore, preparedness for specific actions in practice was self-rated and knowledge was evaluated. The questionnaires were anonymous and participation in the study was voluntary. Results: This research included 180 community pharmacists and 181 physicians. As many as 76 (42.0%) physicians stated they would prescribe an antimicrobial when unsure whether the infection was of viral or bacterial etiology. More than half of the participants considered family medicine doctors the greatest contributors to AMR (N = 216, 59.8%), followed by patients (N = 175, 48.5%). In questions focusing on knowledge, physicians scored significantly higher compared with pharmacists (4.06 ± 1.01 vs. 3.71 ± 1.08, p = 0.001). Conclusion: This research revealed practices among pharmacists and physicians that should be improved and it highlighted gaps in knowledge by both professions. More attention should be given to patient consultation when dispensing and prescribing an antimicrobial as this may reduce their contribution to AMR.
