Syzygium aromaticum is used in combination with other plants as an alcoholic infusion by traditional practitioners to treat infections. It has been selected for evaluation for its antimicrobial properties to justify its use in traditional pharmacopoeia. The fruits were used as plant material while the microbial germs consisted of six reference strains: Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 29213, Salmonella typhimurium ATCC 14028, Pseudomonas aeruginosa ATCC 27853, Shigella flexneri ATCC 12022, Candida albicans ATCC 35659 and their clinical counterparts. The extracts were obtained by aqueous decoction, hydroethanolic and ethanolic macerations. The phytochemical screening was performed by chemical staining tests. The antibiotic susceptibility test was performed using the well diffusion method and the MIC and MBC or MFC were determined using the 96-well microplate dilution method. The results showed that 66.67% of the strains tested were sensitive to the aqueous extract with inhibition diameters ranging from 15 to 21 mm and MIC and MCB or MFC between 0.0976-0.3906 mg/mL and 0.1953-07812 mg/mL respectively, thus determining bacteriostatic activity. 100% of the germs tested were sensitive to hydroethanolic and ethanolic extracts. The inhibition diameters range from 12-28 mm for hydroethanolic extract with MIC and MBC or MFC ranging from 0.0488-0.3906 mm and 0.0488-0.7812 mm respectively. The ethanolic extract gave inhibition diameters of 12-26 mm; MIC and MBC or MFC ranging from 0.

Cochlospermum planchonii is traditionally used in Togo in treating several diseases, including burn wounds which achievement requires anti-infective and good cicatrisation processes. This study aims to evaluate the antimicrobial properties of hydroethanolic extracts from leaves and roots of C. planchonii and its phytochemical composition. Five (05) bacterial strains were suspended in liquid media with plant extracts at various concentrations and then spread, after 24 h incubation, on solid media. The minimum inhibitory (MIC) and minimal microbicidal (MMC) concentrations were assessed. Phytochemical characterization tests were performed and flavonoids, tannins and total phenol contents were also determined. Hydroethanolic extracts from the leaves and roots of C. planchonii were active on all the germs tested, with MICs ranging from 0.782 to 50 mg/mL and MMCs ranging from 1.563 to 100 mg/mL. The bests activities were recorded with root extract against Staphylococcus aureus: MIC=0.782 mg/mL and MMC =1.563 mg/mL. The MMC/MIC ratios are all equal to 2, indicating that both roots and leaves have bactericidal activities rather than inhibitory activities. Phytochemical tests have demonstrated the presence of metabolites such as flavonoids, tannins, carbohydrates, sterols, triterpenes, saponosides, and an absence of alkaloids. Total phenols, tannins and total flavonoids amounts found were respectively 85.466 ± 0.289; 33.566 ± 0.503; 218.333 ± 0.577 µgRE/mg in root extracts, and 75.833 ± 0.289; 26.533 ± 0,053; 183.666 ± 0.577 µgRE/mg in leaf extracts. Both root and leaf hydroethanolic extracts of C. planchonii could be potential natural antimicrobial remedies.

In Togo, the abusive use of the root of Cassia sieberiana D.C. in traditional medicine, contributes gradually to the rarefaction of the species. The general objective of this study is to promote the use of vital organs of Cassia sieberiana in traditional medicine in Togo. The identification of secondary metabolites of the extracts (cyclohexane, dichloromethane and methanol) was carried out by GC-MS and by CL-MS / MS. The antibiotic susceptibility test was performed according to the well diffusion method and the MICs and MBCs according to the tube dilution method. Compounds such as sitosterol α-acetate, β-sitosterol, emodin, chaetochromine, luteolin, (±) -catechin, naringenin 5-O-rhamnoside, guibourtinidol- (4 alpha-> 6) -catechin and (-) - epiafzelechin are found in the root and in the stem bark. The identified molecules give the different methanolic extracts, an antibacterial effect on all the germs tested. At the end of this study, it appears that the chemical composition of the stem bark is almost similar to that of the root bark. The leaves would be better placed for the treatment of bacteria tested.

Annona senegalensis and Securidaca longepedunculata are two plants traditionnaly used in inflammation and wounds infection treatment after snakebites. This study aims to investigate the in vitro anti-inflammatory and antimicrobial activities of the hydroalcoholic extracts of Annona senegalensis and Securidaca longepedunculata. Antimicrobial activity of the two plant extracts was examined against five bacterial strains with the well diffusion method and the inhibition zones diameters (IZD), minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined using the 96-well microplate dilution method. While antiinflammatory activity was assessed by the albumin denaturation method. The results obtained showed that the hydroalcoholic extract of Annona senegalensis has antimicrobial property against Staphylococcus aureus (IZD=12.22 ± 0.24 mm, MIC=62.5 mg/mL, MBC=125 mg/mL) and against Pseudomonas aeruginosa (IZD=12.06 ± 0.06 mm, MIC=125 mg/mL, MBC=250 mg/mL). Securidaca longepedunculata also showed its antimicrobial activity against Staphylococcus aureus (IZD=12.03 ± 0.03 mm, MIC=125 mg/mL, MBC=250 mg/mL) and Candida albicans (IZD=12.12 ± 0.07 mm, MIC=62.5 mg/mL, MFC=125 mg/mL). In the order hand,  Annona senegalensis and Securidaca longepedunculata exhibited concentration-dependent anti-inflammatory activity by reducing significantly (p<0.001)  the denaturation of BSA. In addition  S. longepedunculata inhibited haemolysis significantly (p<0.001) more than Diclofenac sodium at 200 and 400 µg/mL. Hence, it was concluded that Annona senegalensis and Securidaca longepedunculata possessed anti-inflammatory and antimicrobial properties and can be used in the treatment of inflammation and wounds infection after snakebites. Keywords: Annona senegalensis, Securidaca longepedunculata, anti-inflammatory, antimicrobial, BSA.

The general purpose of this article is to help monitor the performance of thewater and food microbiology laboratory at National Institute of Hygienics (NIH)of Lome. To achieve it, thework focused on analyzing trends in customers satisfaction from the laboratory in theperiod from 2012 to 2020. This study mainly took into account the analysis ofcustomers satisfaction levels with satisfaction metrics such as qualityreception facilities, the waiting time, the reliability of the results and the deadline for renderingresults customers complaints analysis as well as analysis of customers suggestions.From the results obtained, it emerged that the majority of the laboratorys customers are satisfiedof its services. Satisfaction rates were over 86% with respect to the quality ofreception facilities, more than 89% concerning waiting time, more than 93% compared tothe reliability of the results and more than 73% for the deadline for rendering results. Claimingcustomers are over 75% cleared and all cleared claims were made within the timeframeresolution expected. Customers suggestions are taken into account through the implementation ofappropriate action plans. However, the analysis of these results has made it possible to identifyinadequacies such as the non-representativeness of the samples from the various satisfaction surveysand the unavailability of certain data which should allow a morethorough. In addition, the available data have shown that the perception of the benefits of thelaboratory by customers, is not growing. However, these data made it possible to achieveto the conclusive results which deserve to be taken into account. In short, it appears clearlythat customers perceptions in the services of the water andfood microbiology laboratory of the NIH of Lome, is satisfactory, even if it is not growing.
