Various studies indicated that endophytic microbes lived in the plant tissues and produced antimicrobial compounds. Sugar-apple plant  (Annona squamosa L) contained alkaloids, cyanogenic glycosides, and flavonoids. The purpose of this reasearch were (1) to determine the endophytic microbes isolated from sugar-apple plant (2) to study inhibiting capabillity of endophytic isolate against Staphylococcus aureus and Candida albicans, (3) to analyze antimicrobial compounds produced by the potential endophytic isolate. Diffusion agar plate methode was used to assessed antimicrobial activity. Antimicrobial compounds were analyzed by Thin Layer Chormatography (TLC) and High Performance Liquid Chormatography (HPLC), compared with erythromycin, metronidazole and tetracycline. Twelve bacterial isolates and 24 fungus were isolated. Selected bacteria, BMC 1.1, showed the biggest clear zone on C. albicans culture on agar medium, meanwhile selected fungi, BTCK 1.1T, formed the biggest colony on S. aureus culture on agar medium. TLC and HPLC analysis showed that the Rf value of BMC 1.1 and BTCK 1.1T chloroform phase fractions was similiar to metronidazole. Metronidazole concentration in C1, C2, Ck1 and Ck2 fraction were 170.98 ppm, 18.27 ppm, 1.51 ppm and 4.14 ppm respectively.

A validation of the method for determination of the microbiological purity of Caffetin® tablets has been done. For this purpose the test microorganisms: Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans and Aspergillus niger from the collection ATCC have been used. A non-specific nutritious medium for aerobic microorganisms and specific nutritious media for adequate test microorganisms: ENDO, Cetrimid, Baird-Parker and Sabouraud nutritious agar medium have been used. The method was performed in two modes: a direct inoculation into a nutritious medium and a membrane filtration. At the same time, a Challenge test was as well used the test of counting the growing colonies (CFU/ml). A calculation of the factor has been done, which represents relationship between growing microorganisms of the inoculated nutritious medium with and without adding to the examined preparation, as a criterion for acceptance of the achieved analytical results. The achieved values for the factor as a criterion for acceptance have shown satisfying values. It can be concluded that this method can be used for determination of the microbiological purity of Caffetin® tablets.

We report our investigations into the underlying differences between 1,2,3-dithiazole and their ultra-rare counterpart, 1,2,3-thiaselenazole. This rare 1,2,3-thiaselenazole chemotype was afforded by sulfur extrusion and selenium insertion into the preconstructed 1,2,3-dithiazoles. We built a library of matched paired compounds to compare and contrast the two ring systems. This led to the development of both narrow and broad-spectrum antimicrobial compounds with sub-micro molar potency, limited to no toxicity and a further understanding of the transition state electronics through molecular simulations. We also identified the potent 4,5,6-trichlorocyclopenta[d][1,2,3]thiaselenazole 11a, for use against Candida albicans, Cryptococcus neoformans var. grubii, Staphylococcus aureus and Acinetobacter baumannii, all of which have limited clinical treatment options. The 1,2,3-thiaselenazole represents a new class of potential compounds for the treatment of a host of multi-resistant hospital derived infections.

ABSTRACT Aim To evaluate and compare antimicrobial effect of various root canal medicaments against Enterococcus faecalis, Staphylococcus aureus and Candida albicans. Materials and methods Six root canal medicaments: 2% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) Calcium hydroxide (Ca(OH)2), EDTA, MTAD and propolis and three microorganisms: Staphylococcus aureus, Enterococcus faecalis and Candida albicans were used. These strains were inoculated in brain heart infusion (BHI) and incubated at 37 degrees C for 24 hours. For the agar diffusion test (ADT), petri plates with 20 ml of BHI agar were inoculated with 0.1 ml of the microbial suspensions, using sterile swabs that were spread on the medium, obtaining growth injunction. Paper disks were immersed in the experimental solutions for 1 minute. Subsequently, four papers disks containing one of the substances were placed on the BHI agar surface in each agar plate. The plates were incubated at 37°C for 48 hours. The diameter of microbial inhibition was measured around the papers disks containing the substances. One way ANOVA followed by Tukey's post-hoc test were used. p-value <0.05 was considered statistically significant. Results Propolis and other irrigants were found to be effective on C. albicans, S. aureus and E. faecalis. CHX and MTAD were found to be most effective amongst all the materials tested followed by propolis. Conclusion Propolis showed antimicrobial activity against E. faecalis, S. aureus, C. albicans. It appears that propolis is an effective intracanal irrigant in eradicating E. faecalis and C. albicans. Clinical significance Propolis is an effective intracanal irrigant in eradicating E. faecalis and C. albicans. It could be used as an alternative intracanal medicament.

<p>The increase of issues on the antibiotics resistant pathogenic bacteria has triggered high exploration for new antimicrobial compounds. One of the potential sources is sponge-associated bacteria. The aim of this study was to get sponge-associated bacteria extract containing antimicrobial activities. On the basis screening of antimicrobial activity using by streaking on agar medium, there were two potential isolates with antimicrobial activities namely LCS1 and LCS2. The two isolates were cultivated,then secondary metabolite product were extracted using methanol as a solvent. Minimum inhibitory concentrations (MICs) of extract LCS 1 were 1,000 μg/well for S. aureus, 950 μg/well for Salmonella sp.and 800 μg/well for Bacillus subtilis. Minimum inhibitory concentrations of extract LCS 2 were 500 μg/well for S. aureus, 1,050 μg/well for Salmonella sp., 750 μg/well for Bacillus subtilis, 350 μg/well for P. aeruginosa, 750 μg/sumur terhadap B. subtilis. Based on the MIC values, the two assay extracts have a relatively low antimicrobial activity.</p> <p>Keywords:Antimicrobial,Sponges associated bacteria,MICs</p>

The medicinal value of the plants is due to their chemical components that bring a definite physiological action on the human body to prevent the diseases. In this work, we investigated the antimicrobial activity of leaves’ extracts of Quercus robur L., collected from the Algerian upper highlands, on ten bacterial strains and one fungal strain known to be pathogenic. First, we performed a qualitative phytochemical analysis, and second, antimicrobial activity tests performed by agar diffusion method (disc and well) with the determination of MIC by broth macro-dilution method. Given the results, it appears that obtained macerates of Quercus robur L. were rich in bioactive phytoconstituents such as alkaloids, anthraquinones, saponins, tannins, and other components. The yield of aqueous and methanolic macerates of leaves was 8.5 ± 1.41 and 22.4 ± 4.36%, respectively. The bacterial resistance was relatively important to several antibiotics, namely, ampicillin, amoxicillin + clavulanic acid for strains of Escherichia coli and Salmonella sp. However, Staphylococcus aureus strains were resistant to fusidic acid, penicillin, and oxacillin; while Enterococcus faecalis was resistant to fusidic acid, penicillin, oxacillin, and ticarcillin. The antibacterial activity of the macerates toward tested microbial strains showed that the aqueous and methanolic macerates of the leaves were proportional to the tested concentration and active not only against Gram-positive and Gram-negative bacteria but also on the fungal species Candida albicans. The estimated MIC for Escherichia coli, Enterococcus faecalis, and Staphylococcus aureus was in the order of 10 mg/mL, which seems more effective than toward Salmonella sp., Klebsiella pneumoniae, Pseudomonas aeruginosa, and Candida albicans which were in the order of 30 mg/mL. These preliminary results confirm that the part of the studied plant had a very good antimicrobial activity that was proportional to the serial concentrations of the tested extracts.
