The aim of this study was to study the antibacterial activity of Silver nanoparticles synthesized by L. acidophilus and the biosynthesis of AgNPs from nonpathogenic bacterial isolates. Fifty samples were obtained during the period from December 2020 to March 2021. AgNO3 was used as a precursor for the synthesis of AgNPs. Biological AgNPs were origi...

... average diameter and three-dimensional structure of silver nanoparticles were discovered using an Atomic Force Microscope (AFM). P. mirabilis produced silver nanoparticles with an average diameter of 45.82 nm (Fig. 3). The color change, XRD, and AFM were used to describe and characterize nanoparticles. As a result, the morphology, size, distribution, and existence of metal composites were ...

... There are several types of diabetes, including type 1, type 2 diabetes, maturityonset diabetes of the young (MODY), gestational diabetes, neonatal diabetes, and diabetes induced by secondary causes such as endocrine system, steroid intake, etc. [2]. Type 1 diabetes is a form of autoimmune disease in which the cells that make insulin are destroyed by the immune system, while type II diabetes, which is more common than type I, occurs when the body does not respond to the insulin produced [3]. The global prevalence of diabetes and impaired glucose tolerance in adults have been increasing in recent decades. ...
... In chronic conditions, diabetes can lead to long-term damage, dysfunction, and failure of various organs, especially the eyes, kidneys, nerves, heart, and blood vessels. A few common complications of diabetes include retinopathy, kidney failure, diabetic foot disorders (severe infection of the legs leading to amputation), and cardiovascular disease [3]. Diabetic skin ulcers appear as painful lesions with the disintegration of skin tissue, including ulcers of the epidermis, dermis, and in many cases, subcutaneous tissue. ...
Insulin therapy is the mainstay of treatment in patients with type 1 diabetes, while diet and lifestyle changes, and if left untreated, insulin therapy are effective in treating type 2 diabetes. Research has shown that the oldest treatment for diabetes was the use of herbs. Thus, various medicinal plants were used to relieve many of the complications of diabetes. This study aimed to assess the effectiveness of various medicinal plants in the treatment of diabetes. The data on medicinal plants and diabetes were collected from related articles published from 2014 to 2021 in reputable databases such as Cochrane, PubMed, Scopus, ScienceDirect, Embase, and SID. Data analysis showed that medicinal plants such as Allium sativum, Cinnamomum verum, Trigonella graecum foenum, Silybum marianus, Citrullus colocynthis, Abelmoschus esculentus, Eryngium, Coriandrum sativum L, and Zingiber officinale were the most frequently used herbs in the treatment of diabetes. Medicinal plants can reduce blood sugar in patients due to having effective medicinal compounds and natural antioxidants and due to the least side effects but longer treatment period.Keywords: Diabetes; Medicinal plants; Remedy; Pharmaceutical Plant
... The same nanoparticle was also used against K. pneumoniae and 19.17 mm inhibition zone was observed at a concentration of 1 mM of AgNPs and 22 mm using 4 mM of AgNPs (Abeer Mohammed et al., 2022). The antimicrobial effects of AgNPs synthesized by Lactobacillus acidophilus (Hussein & Alsharifi, 2021) and leaves extracts of Ficus benghalensis (Maniraj et al., 2019) against P. mirabilis have been studied previously, but, to the best of our knowledge, antimicrobial effects of AgNPs synthesized by P. aeruginosa against P. mirabilis was investigated for the first time in this study. ...
Nanoparticles (NPs) are tiny materials ranging in size from 1 to 100 nm and have unique magnetic, electrical, optical characteristics differing from the bulk materials. They have broad spectrum of applications in pharmaceuticals, electronics, optics, aviation, construction, and automotive industries. Several physical and chemical techniques such as electrochemical, thermal decomposition, chemical vapor deposition, sonochemical reduction and microwave irradiation have been applied to produce metal NPs. Alternatively, green synthesis offers an environmentally-friendly and simple mean for NP preparation. In the present study, silver NPs were produced by Pseudomonas aeruginosa OG1 strain. Characterization of NPs were performed by TEM, SEM and XRD. These NPs were used against pathogenic Proteus mirabilis, which occurs widely in soil and water and shows high level urease activity and forms clear biofilms. It is the cause of 90% of all Proteus infections and frequently related with the catheter-associated urinary tract infections. Silver NPs obtained in the present study were applied to inhibit the growth, urease production, and biofilm formation of P. mirabilis. Growth inhibition zones of 9 mm and 11 mm and, 60 % and 85% antibiofilm effects were obtained by 100 µg/mL and 200 µg/mL NPs, respectively. Urease activity of P. mirabilis was completely inhibited in both concentrations. These results show that the Ag NPs can be used as effective antimicrobial, antibiofilm, and antiurease agents in the fight against pathogens.
Through this study, we show the biological activities of commercially manufactured silver nanoparticles from US Research nano. (USA) and compared it with alcoholic leaf extract Ziziphus spina-christi (Sedr) against Gram-positive bacteria (Staphylococcus aureus, Enterococcus faecalis) and Gram-negative bacteria (Proteus mirabilis, Pseudomonas aerginosa) The efficacy of ten antibiotics against these studied bacteria such as Ampicillin, Erythromycin, Azithromycin, Gentamicin, Vancomycin, Tetracycline, Trimethoprim/Sulfamethoxazole, Ciprofloxacin, Chloramphenicol and Clindamycin was also evaluated. The results showed that the manufactured silver particles had inhibitory activity against S. aureus, E. faecalis, P. mirabilis and Ps. aerginosa is higher than the inhibitory activity of alcoholic leaf extract of Ziziphus spina-christi (Sedr).
