antibacterial properties of honey experiment

In a comparative study of the activities of Manuka honey and Malaysian Tualang honey (Koompassia excelsa) against an extensive spectrum of microorganisms, Tan et al., found that MICs of Tualang honey ranged between 8.75% and 25% which means that Tualang honey has a similar antibacterial activity to Manuka honey with therefore potential for use used for the same medical purposes [68]. Furthermore, a low level of catalase would also mean a high level of hydrogen peroxide. After analysis, the scientists concluded that the vast majority of honey's antibacterial properties come from that protein. This discovery has provoked an increase in the number of studies that have investigated the effect of substances other than peroxide activity. et al.rted the antibacterial properties of honey against two laboratory isolates e.g. Moreover, it is evident that the season also has a noticeable effect on the total phenolic (TP) acid content of honey. The aim of this experiment was to find a solution that may help control the resistance of bacteria to conventional antibiotics. MIC is used to determine the in vitro activity of an antibacterial substance and can be defined as the lowest concentration of an antibacterial agent that will inhibit the visible growth of microorganisms after an overnight incubation [31]. As the antibacterial effects of honey have been shown to be quite potent, a number of studies have sought to draw comparisons with the activities of conventional antibiotics. Even if honey is natural, it is no better than ordinary white or brown sugar for … All samples were tested at different concentrations (0.1%, 1%, 5%, 10%, and 20% (w/v)). This was supported by another study in which solutions of pasture honey 25% (w/v) showed no detectable antibacterial activity in the presence of catalase but an activity equivalent to 14.8% phenol without catalase, whereas the same solution of Manuka honey had activity equivalent to 13.2% with and without catalase [36]. They examined the pattern of use of 43 ingredients and tested their antibacterial properties. A. Imlay and S. Linn, “Bimodal pattern of killing of DNA-repair-defective or anoxically grown, K.

Sign up here as a reviewer to help fast-track new submissions. It was originally believed that hydrogen peroxide is the only factor responsible for the antibacterial effect of diluted honey, and this antibacterial activity of honey could be completely removed by the addition of catalase [50, 51]. These terms were coined by Dold and Witzenhausen in 1955 and involve the formation of a scale of 1 to 5 equal to honey dilutions in 5% steps, from 25% to 5% (w/v) (Table 1). This clearly demonstrates that the pronounced antibacterial activity of New Zealand Manuka honey may be linked to it being rich in MGO [63]. To compare the antibacterial effect of different honey types. coli In other methods, honey is incorporated into the nutrient agar or into the nutrient broth in which the bacterial culture is grown. The susceptibility of Campylobacter jejuni to the antibacterial activity of Manuka honey was also tested, and the results showed that 1% (v/v) of Manuka honey was sufficient to give the minimum inhibitory effect [69]. The phenolic acid level in honey can be affected by its botanical and geographical origin as it depends upon the source of the nectar. The antibacterial effect of honey refers to the experiment that identify the effect of honey on different bacteria growing on agar plates in order to find out the properties present in the honey that help to destroy the Bees collect many materials to produce honey, including nectar, volatiles essential oils, pollen, and propolis, and these various botanical origins will also affect the composition of honey [11]. There are several other methods that have been used to measure the antibacterial activity of honey. Thus, part of the antimicrobial honey components are absorbed while still in the mouth which makes the consumption much more complete. Honey has been in use as a wound dressing for thousands of years.1,2 In the past few decades, there has been a large amount of clinical evidence has been accumulated that demonstrates the effectiveness of honey in this application.3,4 However, it is only in more recent times that the science behind the efficacy has become available. The moisture content of honey can also vary between different honey varieties and can be affected by climate, season, and moisture content of the original plant nectar. It has been known to be very effective in almost all cases of infection and for the promotion of healing especially in burn injury and wounds [6]. Measurement of absorbance using fluorimetry or the spectrophotometric determination of growth has a greater sensitivity especially when used with low honey concentrations [32]. As a result, many studies have analysed the composition of honey and have studied the physical and chemical properties that may give rise to its ability to work against various microorganisms [7]. Moreover, 80% of people depend on these types of treatment in Asian countries such as China and India. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. The method involves preparing two-fold dilutions of honey in a broth and dispensing them to tubes (macrodilution version) or to 96-well microtiter plates (microdilution version). 2.5 Preservation of honey 2.6 Properties and active ingredient of honey 2.7 Mode of action of some antibacterial substance present in honey 2.8 Clinical conditions for treatment with honey 2.9 Honey as an antimicrobial agent 2.10 Practical consideration for the clinical use of honey 2.11 Adverse reaction of honey 2.12 Research on honey. There are different varieties of lemon. The results showed the presence of 14 phenolic compounds which were mainly phenolic acids and flavonoids. Nevertheless, the content of individual carbohydrates did vary and ranged between 329.2 to 426.3 mg/g for fructose and glucose (as the dominant components) [13]. An equivalent activity could be made by using a 15–30% honey dilution which contains similar amounts of MGO. In Lachman et al.’s study, the content was very low and ranged between 82.5 and 242.5 mg/kg honey with the main phenols being flavonoids and phenolic acids [53]. Undiluted honey and its 1 : 2 to 1 : 6 aqueous dilutions showed activity of 100% and 96.4%, respectively, against P. aeruginosa and E. coli. Different proteins have been detected in different honey varieties, predominantly related to different types of honeybees or different types of plants/flowers [27]; however, a group of major royal jelly proteins are shared by all honeybees. Several research studies have investigated honey and its effect on various species of bacteria (Table 3). It is evident that undiluted honey has the ability to stop the growth of bacteria completely because of the high content of sugar; high sugar concentration of honey exerts osmotic pressure on bacterial cells which causes transport of water out of bacterial cells through osmosis. This acidity is due to the presence of organic acids, particularly gluconic acid which is present at ∼0.5% (w/v) [38, 39]. The colour of honey ranges from light yellow, through to amber and dark reddish amber to a nearly black colour [23]. In another in vivo experiment, a significant decrease in the count of E. coli cells in faecal samples was observed in rats that had previously been inoculated orally with E. coli and fed 2 g honey daily for three days in comparison with glucose-, fructose-, and sucrose-fed controls [75]. Myrrh extract. The author declares that there are no conflicts of interest. A study by Alnaqdy et al. In case of raw honey-2, the maximum inhibition as produced by extracts was observed against S. typhi (31.18 mm zone size)> P. aeruginosa(26.00 mm zone size)
