“…The antimicrobial susceptibility testing methods provide reliable results when used according to the previously mentioned standard procedures. As prevalence patterns of microorganisms vary widely and change continually, regional and local resistance must be taken into consideration in the selection of suitable and appropriate antimicrobial agent to combat specific pathogens and to avoid misuse of antibiotics [25][26][27][28]. Recently, resistance to many classes of antimicrobial agents and antibiotics is increasing, which indicates the fact that previous practices during the past period have not been sufficient to prevent the development and spread of resistant pathogens.…”

Due to the globally increasing need for utilizing antimicrobial materials, it is necessary to improve and develop newer methods and techniques for determining the antimicrobial properties of these materials qualitatively and quantitatively, especially in the medical field. Recently there has been a debate among scientists between the difference between antimicrobial test and sterility test. For antimicrobial and microbial resistance, the test is limited to the standard methods to determine the effect of the sample as an antimicrobial without paying attention to the fact that the sample is sterile or not, unless the sample was taken into sterile atmosphere and isolated with a protective suitable sterile package cover after treatment with the antimicrobial agent because the external atmosphere contains a lot of scattered types of bacterial and fungal microorganisms. In case of sterility test, the sample to be examined should be prepared, isolated and coated from the outside atmosphere, where the presence of microbes on the surface of the sample by standard methods is detected and in some sterilization tests it is prohibited to include an antimicrobial substance to the sample to be tested to avoid the interference with the test. In both cases the tests should be implemented in a sterilized room and conditions according to the recognized scientific principles. In conclusions, the antimicrobial test is used to make sure that the specimen is attained antimicrobial properties or not and the sterilization test is done by ensuring that the sample is free of contaminated microorganisms. This review poses on some factor and conditions affecting antimicrobial action and some standard test methods for determination of antimicrobial and sterility potential of materials.

“…To impart antimicrobial characteristics to textiles, different approaches were studied and applied. An easy and common solution encompasses absorption and trapping of an antimicrobial agent in the tissue texture or, on occasion, its grafting onto the surface of polymeric fibers [1][2][3][4][5][6][7][8][9]. Common antimicrobial agents used so far include quaternary ammonium compounds, trichlosan, diclofenac, metal salts, silver compounds, or even natural polymers [1,[10][11][12][13][14][15].…”

Introduction: Bacterial proliferation in health environments may lead to the development of specific pathologies, but can be highly dangerous under particular conditions, such as during chemotherapy. To limit the spread of infections, it is helpful to use gauzes and clothing containing antibacterial agents. As cotton tissues are widespread in health care environments, in this contribution we report the preparation of cellulose fibers characterized by the covalent attachment of lipopeptides as possible antimicrobial agents. Aim: To covalently link peptides to cotton samples and characterize them. Peptides are expected to preserve the features of the fabrics even after repeated washing and use. Peptides are well tolerated by the human body and do not induce resistance in bacteria. Materials and Methods: A commercially available cotton tissue (specific weight of 150 g/m2, 30 Tex yarn fineness, fabric density of 270/230 threads/10 cm in the warp and weft) was washed with alkali and bleached and died. A piece of this tissue was accurately weighed, washed with methanol (MeOH) and N,N-dimethylformamide (DMF), and air-dried. Upon incubation with epibromohydrin, followed by treatment with Fmoc-NH-CH2CH2-NH2 and Fmoc removal, the peptides were synthesized by incorporating one amino acid at a time, beginning with the formation of an amide bond with the free NH2 of 1,2–diaminoethane. We also linked to the fibers a few peptide dendrimers, because the mechanism of action of these peptides often requires the formation of clusters. We prepared and characterized seven peptide-cotton samples. Results: The new peptide-cotton conjugates were characterized by means of FT-IR spectroscopy and X-ray Photoelectron Spectroscopy (XPS). This latter technique allows for discriminating among different amino acids and thus different peptide-cotton samples. Some samples maintain a pretty good whiteness degree even after peptide functionalization. Interestingly, these samples also display encouraging activities against a Gram positive strain. Conclusions: Potentially antimicrobial lipopeptides can be covalently linked to cotton fabrics, step-by-step. It is also possible to build on the cotton Lys-based dendrimers. XPS is a useful technique to discriminate among different types of nitrogen. Two samples displaying some antibacterial potency did also preserve their whiteness index.

“…The leaf extracts of D. stramonium were studied and approved to have excellent antimicrobial activity against micro-organisms based on the availability of large amounts of bio-active compounds such as tannins, flavonoids and alkaloids, which are effective against bacterial and fungal infections (Bhuyan et al, 2016). Also, it has been proved that these antimicrobial agents which have varying composition and concentration in different plant parts are usually accumulated as secondary metabolites in plant cells (Tawiah et al, 2016) and that leaves possess the highest antimicrobial activity levels thus opted for in therapeutic applications (Gutarowska et al, 2013). In respect to that, the use of D. stramonium leaf extract as a textile finish on 100% cotton and silk fabrics and its dyeing potential has not been examined and reported in any form.…”

Functional finishes are agents that are applied to fabrics to make them suitable for specific uses and contribute a specific attribute to a fabric without altering its appearance. In this context, the present study reveals the importance of dyed fabrics with Datura stramonium plant leaf extracts to control antibiotic-resistant bacteria, which have been a threat to human health and posed noticeable challenges confronted with medical physicians in the treatment of many infectious diseases. More still, the importance of using natural dye is not limited to its antimicrobial and other medicine values but also to its wide range of advantages via elimination of environmental pollution due to the usage of synthetic dyes. 100% plain woven, desized, scoured and bleached cotton fabric samples and 100% degummed and bleached hand knitted silk fabric samples were dyed with aqueous extracts from D. stramonium plant leaves in combination with Alum and Iron Sulphate as mordants using post-mordanting method and then tested against two strains of Staphylococus aureus (Gram-positive bacteria) and Pseudomonas aeruginosa (Gram-negative bacteria) using Agar diffusion method as per SN195920-1992 standard. The fastness properties (wash fastness, light fastness and rubbing fastness) of the dyed fabrics were assessed following guidelines from The American Association of Textile Chemists and Colorists (AATCC) and International Organization for Standardisation (ISO) testing methods. Spectrophotometric experiments were employed to evaluate the colour strength (K/S) of the dyed samples. The antimicrobial activity results showed that for both cotton and silk dyed fabric samples; there was an interruption of the microbial growth beneath the fabric and a clear zone of inhibition around the fabric. Dye ability and fastness results showed that dyed fabric samples with D. stramonium extracts using mordants had relatively high colour strength (K/S) values as compared to the control fabrics which were dyed without a mordant and their colorant was more stable to light, rubbing and washing, respectively.
