Sterilization Effect

Abstract In this work, we systematically investigate the sterilization effect of six kinds of commonly used commercial disinfectants, including the DuPont Virkon disinfectant, peracetic acid disinfectant, sodium hypochlorite, bromogeramine disinfectant, water-soluble allicin, and absolute ethanol, against the Escherichia coli, Staphylococcus aureus, Monilia albican and Clostridium sporogenes. The inhibition zone was used to qualitatively determine the antibacterial effects of the six disinfectants, and then the minimum two-fold dilution method was used to quantitatively determine the minimum inhibitory concentration and minimum bactericidal concentration of the six disinfectants on the four pathogens. The result illustrated that the antibacterial effect of peracetic acid disinfectant is the best, and clostridium sporogenes is the most sensitive to it, followed by bromogermine disinfectant, which can inhibit the four pathogenic bacteria at the concentration recommended by the manufacturer. The antibacterial effect of DuPont Virkon disinfectant, sodium hypochlorite, water-soluble allicin and absolute ethanol is not as good as expected, and cannot inhibit the four kinds of pathogenic bacteria at the recommended concentration. In summary, the antibacterial effect of peracetic acid disinfectant is the strongest, followed by the bromogermine disinfectant, DuPont Virkon disinfectant, sodium hypochlorite and water-soluble allicin. The absolute ethanol exhibits the worst antibacterial properties.

Objective: Oral infections and dental caries are considered serious health problems. Therefore, searching for new agents with antimicrobial properties seems to be crucial. This study aimed to evaluate the antimicrobial activity of the recombinant Thrombocidin-1 [TC-1] peptide on some oral pathogens. Also, the cytotoxicity of this peptide on human gingival fibroblast cells was investigated. Methods & Materials: In this study, Pichia pastoris was used for the expression of recombinant TC-1. The microbroth dilution method was used to determine the minimum inhibitory concentration [MIC] and minimum bacterial concentration [MBC]. It tested against four main oral pathogens; Streptococcus mutans, Streptococcus salivarius, Streptococcus oralis, and Enterococcus faecalis. Moreover, the cytotoxicity analysis was done on gingival fibroblast cells by the MTT method. The data were analyzed using a two-way analysis of variance [ANOVA] and Tukey’s HSD tests. Results: The most bactericidal effect of TC-1 was against S. salivarius, the highest bacteriostatic effect was against S. salivarius, and S. oralis had the lowest MIC value of 1.512 μg/ml. The Thrombocidin-1 peptide showed lower antibacterial properties against E. faecalis compared with CHX, unlike the stronger antimicrobial effect on examined streptococci. According to cytotoxicity examination, no concentration of TC-1 presented over 50% growth inhibition [IC50] of the fibroblasts cells. Conclusion: Based on antimicrobial tests and cytotoxicity results, the Thrombocidin-1 peptide may be useful as a safe antibacterial agent against some oral pathogens in dental materials.

Streptococcus mutans is a key bacterium in dental caries- one of the most prevalent chronic infectious diseases. Conventional treatment both fails to specifically target the pathogenic bacteria and at-tempts to eradicate commensal bacteria as well. Thus, caries remains one of most common and challenging diseases. The use of bacterial viruses as anti-bacterial agents, is gaining interest worldwide. Hardly any phages were described against S. mutans. The objective of this study was to isolate anti-S. mutans phages and to characterize their antimi-crobial properties. Human saliva samples were filtered and screened for potential phages. Standard double-layered agar method was used for isolation. Whole genome sequence analysis and morphology visualization by TEM, were used for anti-S. mutans phage identification. Antibacterial properties were evaluated using clinical strains and ATCC strains of S. mutans in various states. Antibacterial effect was also tested on human cariogenic dentin. One phage against S. mutans was isolated and termed SMHBZ8. This phage showed effective lytic activity in vitro against both planktonic and biofilm S. mutans cultures. Moreover, the phage showed antibacterial effect when used on cariogenic dentin. The isolation and characterization of SMHBZ8 may be the first step in developing a potential phage therapy for dental caries.

AbstractMint flavorings are widely used in confections, beverages, and dairy products. For the first time, mint flavoring composition of mint candies and food supplements (n = 45), originating from 16 countries, as well as their antibacterial properties, was analyzed. The flavorings were isolated by Marcussonʼs type micro-apparatus and analyzed by GC-MS. The total content of the mint flavoring hydrodistilled extracts was in the range of 0.01 – 0.9%. The most abundant compounds identified in the extracts were limonene, 1,8-cineole, menthone, menthofuran, isomenthone, menthol and its isomers, menthyl acetate. The antimicrobial activity of 13 reference substances and 10 selected mint flavoring hydrodistilled extracts was tested on Escherichia coli and Staphylococcus aureus by broth dilution method. Linalool acetate and (−)-carvone, as most active against both bacteria, had the lowest MIC90 values. (+)-Menthyl acetate, (−)-menthyl acetate, and limonene showed no antimicrobial activity. Three of the tested extracts had antimicrobial activity against E. coli and 8 extracts against S. aureus. Their summary antimicrobial activity was not always in concordance with the activities of respective reference substances.

A quantitative assessment of the antibacterial effect of silver nanoparticles on polyantibiotic-resistant grampositive and gram-negative microorganisms was carried out. Silver nanoparticles were synthesized by the environmentally friendly metal-steam synthesis method. The size and electronic state of nanoparticles were investigated by transmission electron and X-ray photoelectron spectroscopy. The antibacterial properties of nanomaterials were assessed on two clinical pathogenic strains of gram-positive and four strains of gram-negative microorganisms. The typing and assessment of bacterial resistance to antibiotics were carried out on a microbiological analyzer. The antibacterial effect of nanoparticles was quantitatively assessed using the dilution method and the determination of the minimum inhibitory and minimum bactericidal concentrations.It was found that the studied silver nanoparticles have sizes in the range from 5 to 24 nm with an average diameter of 10.8 nm. It was shown that all clinical strains of microorganisms used in the study are characterized by multiple antibacterial resistance; the percentage of their antibiotic resistance ranges from 12.5 to 93.3 %. It was found that for the studied microorganism, the values of the minimum inhibitory concentration (MIC) are in the range from 7.81 to 31.25 μg/ml, and the minimum bactericidal concentration (MBC) is in the range from 31.25 to 62.50 μg/ml. The obtained MIC and MBC data can be used to create promising antimicrobial drugs and medical next generation devices.

Objectives:: The present study was conducted to evaluate the antimicrobial effects of the recombinant chimer present in the lactoferrampin-lactoferricin [LFA-LFC] derived from the camel milk on some oral bacteria responsible for dental caries and endodontic failures. Methods and Materials:: The antimicrobial activity was assessed on the Streptococcus mutans [ATCC 35668], Streptococcus salivarius [ATCC 9222], Streptococcus oralis [ATCC 35037], and Enterococcus faecalis [ATCC 29212], using the microbroth dilution method. The cytotoxicity analysis was done through the MTT method on the human gingival fibroblasts. The data were reported using the descriptive methods, and were analyzed by the one-way analysis of variance (ANOVA) and Tukey’s honestly significant difference (HSD) test. Results:: Results showed that the chimeric peptide had the highest bacteriostatic effect on S. salivarius with the lowest minimum inhibitory concentration value of 1.22 μg/Ml. Also, LFA-LFC chimer was more effective against S. mutans and S. salivarius compared to using 0.2% chlorhexidine mouthwash. The minimum bactericidal concentration analysis showed the most bactericidal effect against S. mutans [1.256 μg/mL]. In spite of greater antibacterial effect on the evaluated streptococci, this peptide showed the lower bacteriostatic and bactericidal properties against E. faecalis compared to the chlorhexidine. Based on cytotoxicity assay, over 50% of the cells were viable in all the evaluation times demonstrating the biocompatibility of the peptide. Conclusion:: The LFA-LFC chimer revealed comparable or even more effective antibacterial properties compared to the chlorhexidine against the caries-inducing bacteria with no toxicity on the human gingival fibroblast cells. So, this peptide can be used as a safe alternative to the chlorhexidine and other chemicals in the dental applications for prevention and management of the dental caries.

ABSTRACT Chili peppers are a very important crop in Mexico. However, these peppers have been associated with Salmonella infection outbreaks in the United States, and Salmonella and diarrheagenic Escherichia coli pathotypes have been isolated from jalapeño and serrano peppers in Mexico. To decrease microbial contamination of fruits and vegetables, chemical agents are commonly used; however, chemical agents used to eliminate pathogenic bacteria on vegetables have a limited antimicrobial effect. Roselle (Hibiscus sabdariffa) calyces have been reported to have an antimicrobial effect on pathogenic bacteria. In the present study, the antibacterial effect of four roselle calyx extracts (water, methanol, acetone, and ethyl acetate), sodium hypochlorite, colloidal silver, and acetic acid against foodborne bacteria was evaluated on contaminated jalapeño and serrano peppers. The 13 types of foodborne bacteria evaluated were Listeria monocytogenes, Shigella flexneri, Salmonella Typhimurium, Salmonella Typhi, Salmonella Montevideo, Staphylococcus aureus, E. coli O157:H7, five E. coli pathotypes (Shiga toxin producing, enteropathogenic, enterotoxigenic, enteroinvasive, and enteroaggregative), and Vibrio cholerae O1. All 13 types attached to both pepper types, with no significant differences in attachment between jalapeño and serrano peppers. Roselle calyx extract treatment resulted in a greater reduction in levels of all foodborne bacteria than did treatment with sodium hypochlorite, colloidal silver, and acetic acid on both pepper types. Roselle calyx extracts may be a useful for disinfection of chili peppers in the field, processing plants, restaurants, and homes.

Abstract AOAC Method 966.04, the Sporicidal Activity of Disinfectants Test, is a carrier-based test that provides a qualitative measure of product efficacy against spores of Bacillus subtilis and Clostridium sporogenes. For regulatory purposes, Method 966.04 is accepted by the U.S. Environmental Protection Agency (EPA) and the U.S. Food and Drug Administration (FDA) for the generation of product performance data for sporicides and sterilants. In this study, we report on findings associated with proposed improvements (modifications) to the Clostridium component of the method. Egg meat medium (EMM), the culture medium for C. sporogenes currently specified in the method, is no longer commercially available and finding a suitable replacement is critical. In addition, the use of a nonstandardized extract of raw soil as an amendment to EMM, as stipulated in the current method, may result in a highly variable spore suspension. The primary focus of this study was to find replacements for EMM and soil extract. A carrier count procedure, the establishment of target carrier counts (spores/carrier), and a neutralization confirmation procedure were also evaluated. The study was limited to liquid products tested against Clostridium on a hard surface carrier (porcelain penicylinder). Spore suspensions of C. sporogenes were generated using: (1) EMM with soil extract (EMM/SE), (2) cooked meat medium with soil extract (CMM/SE), and (3) cooked meat medium with 5 g/mL manganese sulfate (CMM/MnSO4). The titer of the spore suspension, carrier counts, resistance to hydrochloric acid (HCl), and efficacy against 3 liquid sporicidal agents were used to evaluate the potential of CMM and MnSO4 as replacements. The study was performed by the EPA Office of Pesticide Programs Microbiology Laboratory, Fort Meade, MD. Use of CMM/SE and CMM/MnSO4 resulted in comparable results for titer of spore suspensions (approximately 108 spores/mL) and carrier counts (approximately 3 106 spores/carrier). The carrier counts for the EMM/SE were approximately 1 log lower than CMM-based treatments; however, no attempt was made to dilute the CMM spore suspensions prior to carrier inoculation to reduce the carrier counts for CMM. Resistance of spores to 2.5 M HCl was acceptable across the 3 media types. Treatments for comparative efficacy testing were designed to provide a range of sporicidal activity, i.e., high and low efficacy treatments. Sodium hypochlorite (bleach), hydrogen peroxide/peracetic acid, and glutaraldehyde were used as test chemicals. The number of carriers resulting in growth (positive) for the low treatments for all 3 chemicals ranged from 9 to 59 out of 60 across the 3 media typesEMM exhibited fewer positives overall. The high efficacy treatments for sodium hypochlorite and hydrogen peroxide/peracetic acid yielded a range of 0 to 2 positives out of 60 across the 3 media. However, the high glutaraldehyde treatment generated 3, 20, and 20 positives out of 60 for the EMM/SE, CMM/SE, and CMM/MnSO4, respectively. The lower number of positive carriers for EMM/SE may be due to the reduced carrier counts. CMM, either with SE or MnSO4, appears to be a suitable replacement for EMM/SE. On the basis of the results of this study, the Study Director recommends that CMM/MnSO4 and the spore enumeration target carrier count and neutralization procedures be considered for collaborative study to officially modify the Clostridium porcelain component of Method 966.04.

Background: One of the most common health problems is infectious diseases. Infectious disease can be caused by bacteria. There were two groups of bacteria based on the staining, Gram-positive and Gram-negative bacteria. Purpose: Antibiotics are the main therapy used in the incidence of bacterial infections. But over time, some antibiotics became resistance. Several studies have shown that garlic has an antibacterial effect. The content of allicin, ajoene, saponins, and flavonoids is found in garlic which has antibacterial properties. The antibiotic activity test of garlic was carried out on the bacteria Streptococcus pyogenes and Pseudomonas aeruginosa. The goal of this study is to investigate the antibacterial effect of Allium sativum L. extract against Streptococcus pyogenes and Pseudomonas aeruginosa. Methods: Garlic extract was made using the maceration method using 96% alcohol as the solvent. Tube dilution method elected to observe garlic antibiotic activity. This test aims to determine the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC). There were eight different concentration used, i.e. 2 grams/ml, 1 gram/ml, 0.5 gram/ml, 0.25 gram/ml, 0.125 gram/ml, 0.0625 gram/ml, 0.03125 gram/ml, and 0.015625 gram/ml. Replication is done three times. Results: In this experiment, the extract produced was turbid that MIC could not be determined and there was no momentous differentiation between before and after treatment. There was no growth of Streptococcus pyogenes in 1 gram/ml and Pseudomonas aeruginosa in 0.5 gram/ml. This number indicates the MBC for each bacteria. Conclusion: Garlic (Allium sativum L.) has an effect of bactericidal activity, it can perform as an antibacterial for Streptococcus pyogenes and Pseudomonas aeruginosa. Garlic extract was more effective for Pseudomonas aeruginosa than Streptococcus pyogenes.

Initial Stage

Infection is a disease caused by the presence of pathogenic microbes, including Staphylococcus aureus and Escherichia coli. Garlic (Allium sativum L.) has chemical contents such as allicin, alkaloids, flavonoids, saponins, tannins, and steroids, which can function as an antibacterial against Staphylococcus aureus and Escherichia coli. This study aims to determine the antibacterial properties of garlic extract powder against Staphylococcus aureus and Escherichia coli. This research is the initial stage of the development of herbal medicines to treat Staphylococcus aureus and Escherichia coli infections. The antibacterial activity test was carried out by the liquid dilution method. The concentrations used were 30 mg/mL, 40 mg/mL, 50 mg/mL, 60 mg/mL and 70 mg/mL. The results showed that the Minimum Inhibitory Concentration (MIC) against Staphylococcus aureus and Escherichia coli was 40 mg/mL and 50 mg / mL. Minimum Bactericidal Concentration (MBC) results for Staphylococcus aureus and Escherichia coli are 50 mg/mL and 70 mg/mL. Based on the Simple Linear Regression test, the R2 value of Staphylococcus aureus and Escherichia coli is 0.545 and 0.785, so it can be concluded that there is an effect of garlic extract powder on the growth of Staphylococcus aureus and Escherichia coli by 54.5% and 78.5%. Garlic (Allium sativum L.) extract powder has potential as herbal medicine against bacterial infections but requires further research to determine its effect in vivo.
