“…Recently and after our revision, Morgan [30] shown that MO powder significantly reduced 87% E. coli colonies in contaminated water and also similar result as well have been reported by Vunain [31] by reduction of microbial load through turbidity reduction. In addition, a single 100 mg of MO seed powdered is the quantity required to eradicating 99.9% of the microbial load from 1 L of water [32]. Although water turbidity reduction implies a reduction of pathogens it is not clear whether they remain in the water or are deposited in the sludge resulting from water treatment.…”

Plant extracts have been used as alternatives to the conventional chemical water treatment. Moringa oleifera Lam. is one of the plants used for this purpose due to its antimicrobial and coagulant properties. However, there is no systematization of Moringa's application methodology. Different parts of the plant, extraction methods and concentrations can be applied to remove several pathogens present in contaminated drinking water. In the present work, reported Moringa applications with antimicrobial effect were systematically reviewed, in order to identify effective methodology(ies) for water treatment. Forty-nine articles were screened for: (1) part of the plant used, (2) extraction method, (3) extract concentration, (4) targeted pathogens, and (5) inhibition zone obtained. Nine articles complied with these criteria and were carefully analyzed; eight of them reported on leaf extracts and only one on seed extracts. Two approaches were used: analysis by pathogen and overall analysis. A total of eight different extraction methods were reported. Extract concentrations used ranged from 0.02 to 800 mg mL −1 and were tested on twenty pathogens. Our analysis revealed that none of such methods is effective against all the tested pathogens. However, leaf extracts obtained with distilled water or with 95% ethanol were the most effective ones for a higher number of pathogens such as Escherichia coli and, possibly, Vibrio cholerae. Moreover, Moringa's extract concentration of 30 mg mL −1 obtained by the 95% ethanol extraction method was the most efficient. Findings suggest an effective procedure to use Moringa, reinforcing its importance as an environmentally friendly alternative for water treatment in areas lacking a water supply system.

“…The results indicated that MO has superior antimicrobial activity among EOs. Virk et al (2019) has reported antagonistic activity of MO against S. aureus and E. coli. LABs showed MIC values ranging from 1.90 to 0.48 mg mL -1 against E. faecalis (MW051601) which is in accordance with Nazareth et al (2019), who reported MIC values of LABs ranging from 125 to 4 g/L against fungi.…”

In vivo studies could not confirm in vitro prophylactic synergism between Moringa essential oil and Lactobacillus reuteri (MT180537)

Aerobic vaginitis (AV) is a recently defined vaginal recurring infection, which is treated with antibiotics. However, excessive and prolonged use of antibiotics disrupts healthy vaginal microflora and leads to the emergence of antibiotic resistance among pathogens. This situation has directed researchers to explore alternative antimicrobials. The current study describes in vitro and in vivo antimicrobial efficacy and pharmaceutical interactions between plant essential oils (EOs) and five lactic acid bacteria (LABs), isolated from the healthy vagina, against E. faecalis, one of the major etiological agents of AV. In vitro experiments confirm good antimicrobial activity of both plant EOs and cell free supernatant (CFS) from LABs. Based on high antimicrobial efficacy, Moringa essential oil (MO) was selected to determine its nature of interaction with CFS of five LAB strains. Synergism was recorded between MO and CFS of L. reuteri (MT180537). To validate in vitro findings, prophylactic responses of individual and synergistic application of MO and L. reuteri (MT180537) were evaluated in an E. faecalis (MW051601) induced AV murine model. The prophylactic efficacy was evidenced by a reduction in intensity of clinical symptoms, E. faecalis (MW051601) count per vaginal tissue along with a reduction in AV associated changes in histological markers of infection in animals receiving Moringa essential oil and L. reuteri (MT180537) alone or in combination. However, significant synergism between Moringa essential oil and L. reuteri (MT180537) could not be observed. Our data confirms the importance of in vivo experiments in deducing pharmacological interactions.

“…The fine moringa seed powder (moringa-teabag) was previously produced by Diocesan Caritas of Bissau. Then, moringa-teabags were prepared by us, each containing 2 g of moringa seed powder, to be diluted in 20 L of water (i.e., in a proportion of 100 mg/L) for 5 min, which has the potential to eliminate 99.9% of several pathogenic bacterial strains ( Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, Staphylococcus aureus, and methicillin-resistant Staphylococcus aureus ( MRSA) [ 34 ].…”

Moringa as a household water purification method – community perception and pilot study in Guinea-Bissau

et al. 2022

View full text Add to dashboard Cite

Background Public perceptions of water-related issues are still under-researched topics. The current paper intends to explore a local community’s perceptions regarding household water purification (HWP) strategies, namely before and after trying a new method: moringa seeds powder (moringa-teabag). Methods In September 2020, six focus group discussions (N = 65) assessing perceptions about the usefulness of Moringa oleifera Lam (Moringaceae) as a HWP method (before moringa-based HWP trials), and questionnaires (N = 104) evaluating successes and identifying difficulties (after one week of moringa-based HWP trials). Participants were all women aged over 18 years, living in Ondame, Biombo region, Guinea-Bissau. Data were analyzed using qualitative and quantitative approaches. Results The focus group discussions revealed that people are aware of the fact that water can transmit diseases. Although certain persons showed concern about shallow well water safety, people generally underestimate the risk, as they trust tubewell water. Not everyone had an understanding of what water contamination is, or the concept of medical importance. Some respondents declared they use traditional methods such as boiling and bleach to treat water before drinking. However, those who reported no kind of treatment indicated reasons such as lack of time, cost, and bleach’s taste and smell. In the questionnaire, more than half of the participants (68%) reported treating water before consumption. Nevertheless, these results are not consistent with our field notes. Participants demonstrated a strong belief in the capacity of moringa-teabags to purify water and even consider them better or much better (81%) than other methods. Participants asked for more information on moringa-teabag for household water purification. Conclusion More information on water treatment and water safety would help to raise public awareness about waterborne diseases. These findings could be used to promote greater adherence to moringa-based HWP as an alternative to household water treatment.
