Antimicrobial activity of Eucalyptus globulus oil, xylitol and papain: a pilot study

Abstract

Objective:To evaluate the in vitro antimicrobial activity of the Eucalyptus globulus essential oil, and of the xylitol and papain substances against the following microorganisms: Pseudomonas aeruginosa; Samonella sp.; Staphylococus aureus; Proteus vulgaris; Escherichia coli and Candida albicans. Method: The in vitro antimicrobial evaluation was used by means of the agar diffusion test and evaluation of the inhibition zone diameter of the tested substances. Chlorhexidine 0.5% was used as control. Results: The Eucalyptus globulus oil showed higher inhibition than chlorhexidine when applied to Staphylococcus aureus, and equal inhibition when applied to the following microorganisms: Escherichia coli, Proteus vulgaris and Candida albicans. Papain 10% showed lower antimicrobial effect than chlorhexidine in relation to Candida albicans. Xylitol showed no inhibition of the tested microorganisms. Conclusion: The Eucalyptus globulus oil has antimicrobial activity against different microorganisms and appears to be a viable alternative as germicidal agent hence, further investigation is recommended.

Effects of Fruit Maturity Stages on GC-FID Fatty Acid Profiles, Phenolic Contents, and Biological Activities of Eucalyptus marginata L.

“…e highest inhibition diameters were seen with the vegetable oil of immature Eucalyptus marginata fruits with 21 mm against Staphylococcus aureus, 19 mm against Escherichia coli, and 18 mm against Enterococcus faecalis. Our results were in agreement with those found by Mota et al [26], who demonstrated that the essential oil from Eucalyptus tereticornis Sm exhibited antibacterial activity.…”

“…Both Candida species are more sensitive to the VCZ30 fungicide with an inhibition diameter of 35.5 mm. e obtained results confirm those of Mota et al [26], who reported that the essential oil of Eucalyptus tereticornis Sm has also fungicide activity able to completely destroy Saccharomyces spp., Sporobolomyces, and Hansenula.…”

Evaluation of Antibacterial and Antibiofilm Activity of Cinnamon, Clove, Eucalyptus, and Tea Tree Oils Against Oral Streptococci

“…The present study also indicated that eucalyptus oil was highly active against 8 out of ten isolates, and partially active against a multispecies sample. This coincides with a study by (Mota et al, 2015) who demonstrated that Eucalyptus globulus essential oil has a more potential antimicrobial activity than chlorhexidine against gram-positive and gram-negative bacteria.…”

Papain Ameliorates Lipid Accumulation and Inflammation in High-Fat Diet-Induced Obesity Mice and 3T3-L1 Adipocytes via AMPK Activation

“…As a popular folk remedy, papain was used to reduce pain, inflammation, infection, swelling, diarrhea, and allergies, in addition to improving digestion. It is also known for its wound healing properties [12], antibacterial activity [13], and exhibits inhibitory effects on platelet activation [14], monocyte-platelet aggregate formation [15], strongyloidiasis [16], atherosclerosis [17] and peritoneal adhesion [18]. However, its effect on obesity has not been studied.…”
