The Effect of Cinnamomum burmannii Water Extraction Against Staphylococcus aureus, Enterobacter spp., Pseudomonas aeruginosa, and Candida albicans: In Vitro Study

Abstract

Indonesian cinnamon (Cinnamomum burmannii) is a native plant of Indonesia that has a lot of potential. The most consumed part is the bark. This study aims to examine the antimicrobial effect of Cinnamomum burmannii bark extract on various types of pathogenic microbes, namely Staphylococcus aureus, Enterobacter spp., Pseudomonas aeruginosa, and Candida albicans. An experimental study using a water extract (infusion) of Cinnamomum burmannii bark and a microbial test obtained from the Faculty of Pharmacy, Widya Mandala Catholic University, Surabaya. The antimicrobial effect test was carried out by the microdilution method in 96-well-microplate to determine the Minimum Inhibitory Level (MIC) and implantation on solid media to determine the Minimum Kill Rate (KBM). The MIC and KBM against Staphylococcus aureus were 625-1,250 ppm and 1,250-2,500 ppm, respectively. MIC and KBM for Enterobacter spp., Pseudomonas aeruginosa, and Candida albicans were not found at the highest concentrations tested at 10,000 ppm. Cinnamomum burmannii extract can be used as a potential ingredient with antimicrobial effects, especially against Gram-positive bacteria. Future studies should pay attention to the quality of simplicia, particle size, and the most effective extraction methods extracting antimicrobial substances from simplicia

Effect of Ciprofloxacin, Levofloxacin, and Ofloxacin on Pseudomonas aeruginosa : A case control study with time kill curve analysis

“…So it is more appropriate to use the time-kill curve method to observe antibiotic activity after microorganisms are exposed to antibiotics. The information obtained is more detailed and dynamic because this method shows antibiotic activity that depends on the amount of concentration and time [ 12 , 13 ].…”

Trans-Cinnamaldehyde Inhibitory Activity Against <i>mrkA</i>, <i>treC</i>, and <i>luxS</i> Genes in Biofilm-forming <i>Klebsiella pneumoniae</i>: An In Silico Study

“…24,25 Cinnamon has an antibacterial effect on a variety of pathogenic microorganisms, including Candida albicans, Staphylococcus aureus, Enterobacter spp., and Pseudomonas aeruginosa. 26 Trans-cinnamaldehyde (trans-CNMA), a naturally occurring antibacterial and antibiofilm substance has been demonstrated to exhibit efficacy against commensal, enterohemorrhagic, and uropathogenic Escherichia coli (UPEC) strains in addition to Methicillin-resistant Staphylococcus aureus strains. Numerous CNMA analogs have recently been found to have antibiofilm actions on strains of Streptococcus pyogenes, Vibrio species, and Candida albicans.…”

Evaluation of fluconazole, itraconazole, and voriconazole activity on Candida albicans: A case control study

“…There are at least 15 Candida species that can cause human disease, but the following five pathogens cause more than 90% of invasive infections: Candida albicans , Candida glabrata , Candida tropicalis , Candida parapsilosis , and Candida kruse i [ [1] , [2] , [3] ]. Based on the SENTRY antifungal surveillance program from 1997 to 2016, of the 20,788 isolates admitted, 46.9% were Candida albicans , 18.7% Candida glabrata , 15.9% Candida parapsilosis , 9.3% Candida tropicalis , 2.8% Candida krusei , and 6.5% Candida spp., [ 4 , 5 ]. A study in Asia found that Candida albicans caused the highest incidence of candidemia with a total of 41.36%, followed by Candida tropicalis at 25.45%, Candida glabrata at 13.93%, and Candida parapsilosis at 12.15%.…”
