The COVID-19 literature is limited regarding bacterial infections. If bacterial infections drive mortality in respiratory viruses, this has clear implications for patient management. To address this limited literature problem, we review current knowledge on bacterial infections in COVID-19, assess information from past viral respiratory pandemics, and determine the most prevalent infections. We also study antibiotic misuse during the COVID-19 pandemic. The findings of this study conclude that there is a need to consider presence or absence of bacterial infection in COVID-19 management. Early determination and antibiotic treatment are of importance, however not all patients who are tested for COVID -19 are also tested for bacterial infections which may exacerbate the disease. Physicians utilised antibiotics as a treatment for COVID -19 for various reasons, this posed a risk of antibiotic overuse and antimicrobial resistance when administered in patients with no bacterial infection. While lack of access to antibiotics could be dangerous in the same vein as its misuse, it is of importance to ensure that these life-saving agents are preserved and used with utmost care.

The continuous use of synthetic antibiotics will not only kill bacteria but also can accelerate the emergence of resistant pathogenic races. In addition, it can also cause the death of normal flora. Coffee extract is reported to have the potential as a naturally active and non-toxic antibacterial compound suitable for biomedical applications. Extraction using methanol was carried out on green coffee and which had been roasted for three types of Jambi coffee, namely Arabica, Robusta and Liberica coffee and continued with fractionation using hexane and ethyl acetate. The results of the analysis using FTIR showed that OH, C-H, C = C, C = O, C-O, C-N and N-H groups were detected. These functional groups are probably the functional groups that belong to caffeine, trigonelline, nicotinic acid and dehydrocafestol, which are believed to have bacteriostatic effects on some bacteria. The SEM-EDX analysis results of the three types of coffee showed that the dominant elements were O, K and Mg. Potassium and magnesium minerals bind with chlorogenic acid to form salt complexes of chlorogenic acid and magnesium chlorogenic acid complex. The antibacterial activity of the coffee extract and fraction was still low with the diameter of the inhibition zone was still low (0-10 mm). Furthermore, further characterization and tests are needed to confirm the antibiotic potency of the Arabica, Robusta and Liberica coffee ethanol extracts.

Introduction: The certain commonly used antibiotics (cefixime, metronidazole, ciprofloxacin, cefpodoxime and cetirizine) purchased from the chemist shop in Mokokchung town, Nagaland and effects on mitotic activity of root tip meristematic cells of Allium Cepa were observed. Methods: The different concentrations were prepared by retaining the original effective concentrations (400, 400, 500, 200 and 10 mg) of the antibiotics and treated the root tips of Allium at different times (6, 12 and 24 h) to record the effects or abnormalities. Results: All the concentrations (ppm) and time (h) were effective to induce the chromosomal disturbances during the mitotic activity of root tip cells in Allium. Conclusion: The mean value (\±S.E.) recorded for mitotic cells, mitotic stages, physiological and clastogenic abnormalities and showed a mixed response which could not predict dose response curve in actual.
