Antibacterial And Antifungal

Currently, the increasing resistance of microorganisms to antibiotics is a serious problem. Marine organisms are the source of thousands of substances, which also have antibacterial and antifungal effects. Among them, marine macrolides are significant. In this review, the antibacterial and/or antifungal activities of 34 groups of marine macrolides are presented. Exemplary groups are chalcomycins, curvulides, halichondramides, lobophorins, macrolactins, modiolides, scytophycins, spongistatins, or zearalanones. In the paper, 74 antibiotics or their analog sets, among which 29 with antifungal activity, 25 that are antibacterial, and 20 that are both antifungal and antibacterial are summarized. Also, 36 macrolides or their sets are produced by bacteria, 18 by fungi, ten by sponges, seven by algae, two by porifera, and one by nudibranch. Moreover, the chemical structures of representatives from each of the 34 groups of these antibiotics are presented. To summarize, marine organisms are rich in natural macrolides. Some of these may be used in the future in the treatment of bacterial and fungal infections. Marine macrolides can also be potential drugs applicable against pathogens resistant to currently known antibiotics.

Abstract Aim The aims of the study are to investigate the bactericidal effect of three antiseptics (chlorhexidine solution, povidone-iodine solution, and Walkhoff solution) and to determine the minimum inhibitory concentration and their effect on different microbial species. Methods and Materials The study was performed on microflora derived from root canals with simple and complicated pulp gangrene and on pure strains of Enterococcus and Candida albicans. Results Chlorhexidine and povidone-iodine proved to have antibacterial and antifungal effects if used in the treatment of pulp gangrene and in cases not responding to conventional therapy. Conclusion According to the obtained results, the spectrum of antibacterial agents used in infected canal irrigation can be enlarged to include the agents tested. Citation Shurrab MY.

Antibacterial And Antifungal

Infectious diseases caused by fungi and bacteria are among the major causes of illness and death worldwide. This is mainly implicated by the antimicrobial resistance of the current treatment regimens. Since plant products are house stores of bioactive compounds, it is essential to screen plant-based antimicrobials to come up with novel medicines that counter the grave consequences of antimicrobial resistance. In the folk medicine of Ethiopia, Aloe megalacantha is used for the treatment of wound, dandruff, malaria, diabetes, impotence, colon cleansing, amoeba, ascariasis, abdominal pain, urine retention, snake bite, and evil eye. Hence, the present study was aimed to evaluate the antibacterial and antifungal effects of the leaf exudate of Aloe megalacantha. Agar well diffusion was employed to determine the antibacterial and antifungal effects. Six bacterial strains, namely, S. aureus (standard), S. aureus (clinical isolate), E. coli ATCC 25922 (standard), E. coli (clinical isolate), K. pneumoniae (standard), and P. aeruginosa ATCC 27853 (standard), and four fungal strains such as C. albicans, C. glabrata, C. tropicalis, and C. krusei were studied. The leaf exudate showed the highest activity against C. krusei with an average zone diameter of 22.49 ± 0.47 mm at 400 mg/mL. Among the bacterial species, S. aureus ATCC 29213 (standard) was the most sensitive with an average zone of diameter of 16.63 ± 0.12 mm at 200 mg/mL. Thus, the present findings support the folklore use of Aloe megalacantha for the treatment of different microbial infections.

Abstract The aim of the experiment was a green synthesis of cobalt nanoparticles from the aqueous extract of Ziziphora clinopodioides Lam (CoNPs) and assessment of their cytotoxicity, antioxidant, antifungal, antibacterial, and cutaneous wound healing properties. The synthesized CoNPs were characterized using different techniques including UV–Vis., FT-IR spectroscopy, X‐ray diffraction (XRD), energy dispersive X-ray spectrometry (EDS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). According to the XRD analysis, 28.19 nm was measured for the crystal size of NPs. TEM and SEM images exhibited a uniform spherical morphology and average diameters of 29.08 nm for the biosynthesized nanoparticles. Agar diffusion tests were done to determine the antibacterial and antifungal characteristics. Minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and minimum fungicidal concentration (MFC) were specified by macro-broth dilution assay. CoNPs indicated higher antibacterial and antifungal effects than many standard antibiotics (p ≤ 0.01). Also, CoNPs prevented the growth of all bacteria at 2–4 mg/mL concentrations and removed them at 2–8 mg/mL concentrations (p ≤ 0.01). In the case of antifungal effects of CoNPs, they inhibited the growth of all fungi at 1–4 mg/mL concentrations and destroyed them at 2–16 mg/mL concentrations (p ≤ 0.01). The synthesized CoNPs had great cell viability dose-dependently and indicated this method was nontoxic. DPPH free radical scavenging test was done to assess the antioxidant potentials, which revealed similar antioxidant potentials for CoNPs and butylated hydroxytoluene. In vivo experiment, after creating the cutaneous wound, the rats were randomly divided into six groups: untreated control, treatment with Eucerin basal ointment, treatment with 3% tetracycline ointment, treatment with 0.2% Co(NO3)2 ointment, treatment with 0.2% Z. clinopodioides ointment, and treatment with 0.2% CoNPs ointment. These groups were treated for 10 days. For histopathological and biochemical analysis of the healing trend, a 3 × 3 cm section was prepared from all dermal thicknesses at day 10. Use of CoNPs ointment in the treatment groups substantially raised (p ≤ 0.01) the wound contracture, hydroxyl proline, hexosamine, hexuronic acid, fibrocyte, and fibrocytes/fibroblast rate and remarkably decreased (p ≤ 0.01) the wound area, total cells, neutrophil, and lymphocyte compared to other groups. In conclusion, CoNPs can be used as a medical supplement owing to their non-cytotoxic, antioxidant, antibacterial, antifungal, and cutaneous wound healing effects. Additionally, the novel nanoparticles (Co(NO3)2 and CoNPs) were good inhibitors of the α-glycosidase, and cholinesterase enzymes.
