  • The skin is colonized by a large number of microorganisms with a stable composition of species. However, disease states of skin such as acne vulgaris, psoriasis, and atopic dermatitis have specific microbiome compositions that are different from those of healthy skin. The target modulation of the skin microbiome can be a potential treatment for these skin diseases. Quorum sensing (QS), a bacterial cell-cell communication system, can control the survival of bacteria and increase cell density. Also, QS affects the pathogenicity of bacteria such as biofilm formation and protease production. In this study, we confirmed anti-QS activity of Amorepacific patented ingredients, which are Lactobacillus ferment lysate (using Lactobacillus plantarum APsulloc 331261, KCCM 11179P) through bio-reporter bacterial strain Chromobacterium violaceum. The purple pigment production of C. violaceum controlled by QS was reduced 27.3% by adding 10 ㎍/mL of Lactobacillus ferment lysate (freeze dried). In addition, the Lactobacillus ferment lysate increased growth of Staphylococcus epidermidis 12% and decreased growth of Pseudomonas aeruginosa 38.5% and its biofilm formation 17.7% at a concentration of 10 ㎍/mL compared to the untreated control group. Moreover, S. epidermidis was co-cultured with the representative dermatological bacterium Staphylococcus aureus in the same genus, the growth of S. epidermidis was increased 134 % and the growth of S. aureus was decreased 13%. These results suggest that fermented lysate using Lactobacillus plantarum APsulloc 331261 may be useful as a cosmetic ingredient that can control the balance of skin microbiome.

  • The antimicrobial activity of methanol extracts from 17 seaweeds was screened using a paper disc method and using three human skin pathogens: Staphylococcus aureus, S. epidermidis and Candia albicans. The serial extraction of Neorhodomela aculeata was also conducted using four different solvents (n-hexane, chloroform, ethyl acetate, and methanol) and the minimal inhibitory concentration (MIC) of each extract was examined for the three pathogens. Of the 17 seaweeds, the MeOH extracts of Ulva conglobata, N. aculeata and Symphyocladia latiuscula showed antimicrobial activities. For the extracts from N. aculeata and S. latiuscula, the inhibition zones were more than 10 mm in diameter against S. aureus and S. epidermidis, and >7mm for C. albicans. The inhibition zone of U. conglobata treatment was about 8 mm for S. aureus only. The MIC of each N. aculeata extract ranged from 8 to 32 mg/mL against the three human skin pathogens, and the lowest value (8 mg/mL was with the methanol extract. These results suggest that the MeOH extract of N. aculeata might be useful for developing new antibiotics against human skin pathogens.

  • The antimutagenic activities of ethanol extracts of Korean and American propolis were tested using Salmonella Typhimurium TA98 with two indirect mutagens of 3-amino-1,4-dimethyl-5H-pyrido [4,3-b]indole (Trp-P-1) and 2-aminoanthracene (2-AA) with S9 mix. Additionally, their antimicrobial activities against acne-related pathogenic strains of Propionibacterium acnes, Staphylococcus Epidermidis, Staphylococcus aureus and Pseudomonas aeruginosa were evaluated using both paper disk method and agar dilution method. Ethanol extracts of Korean and American propolis showed strong inhibitory effects, in a dose dependant manner, against the mutagenicities induced by Trp-P-1 and 2-AA. The antimutagenic effect of ethanol extracts of Korean propolis showed significantly higher protective activity than that of American propolis against the Trp-P-1 induced mutagenicity of S. Typhimurium TA98 at the lower concentration ($1-10\;{\mu}g$), but significantly lower protective activity at the higher concentration ($50-200\;{\mu}g$). The antimutagenic effect of ethanol extract of Korean propolis showed significantly higher protective activity than that of American propolis against the 2-AA induced mutagenicity at the concentration of $1\;{\mu}g$, but significantly lower protective activity than that of the American at the higher concentration ($50-200\;{\mu}g$). Both extracts showed strong antimicrobial activities against all the acne-related pathogens tested, with minimal inhibitory concentration (MIC) values in the range $1,500-5,000\;{\mu}g/mL$.

  • Lonicerae Flos was extracted with methanol and successively fractionated with petroleum ether, chloroform, ethyl acetate, and methanol to investigate their antimicrobial effects against food-borne pathogens and food spoilage bacteria using paper disc method. Ethyl acetate extracts of L. Flos showed highest antimicrobial activity against Shigella dysenteriae. Synergistic effect in inhibition was observed when L. Flos extract was mixed with Artemisa capillaris extract as compared to using each extract alone. Growth inhibition curves were determined using ethyl acetate extracts of L. Flos against Staphylococcus epidermidis and S. dysenteriae. Ethyl acetate extract of L. Flos had antimicrobial activity against S. dysenteriae at 3,000 ppm, retarding growth of S. dysenteriae up to 12 hr.

  • Hibiscus cannabinus L. is a plant in the Malvaceae family, that was seeded at June 1st in 2010 and harvested at November 18th. The present study was designated to investigate the safety for host cells, antibacterial effects of Hibiscus cannabinus L. of flower (HCME-F) or leaf (HMEF-L) methanol extract for typical Gram's positive bacteria (St. aureus and Str. epidermidis) or Gram's negative bacteria (S. typhimurium and E. coli). In treatment of different concentrations of HCME-F or HMEF-L (1, 50 and $100{\mu}g/ml$), cytotoxic effects were not shown to RAW 264.7 cells until 24 h incubation. In determination of antibacterial activity of HCME-F or HMEF-L, the antibacterial activities for St. aureus and Str. epidermidis were markedly increased compared to that of untreated control group, but antibacterial activity of HCME-F or HMEF-L for S. typhimurium and E. coli were not changed. Taken together, we demonstrated that methanol extract of HCME-F or HMEF-L showed the safety for RAW 264.7 cells and antibacterial activities for Gram's positive pathogenic bacteria St. aureus and Str. epidermidis. These findings suggest that a methanol extract of Kenaf flower or leaf may be useful alternatives of conventional chemotherapies for dermatitis and mastitis causing Gram's positive pathogens such as Stapylococcus spp. and Streptococcus spp. in domestic animals and humans.

  • A total of 8 strains of Staphylococcus epidermidis isolated in land-marine tank system of Kyongnam and Kyongbuk. Prefecture were tested for the biological and biochemical characteristics. These strains were isolated from pathologic specimens of cultured flounder. Paralichthys olivaceus. Growth of the isolates was good on BHIA, HIA. Staphylococcus No. 110 and ETGP. Growth was good at NaCl concentration between 2.0 and 3.0%, about $30^{\circ}C$ and at pH values about 7.0. DNase and coagulase production were negative, and all isolates except FSJ-2 strain were positive in hemolysis. Urease was positive reaction, and novobiocin resistance was negative. Acid was produced anaerobically from glucose and maltose. All isolates except FSJ-19 strain produced weakly were negative in anaerobic acid production from mannitol. Acid was produced aerobically from glucose, fructose, galactose, sucrose, maltose and dextrine. But all isolates were not gas production. In characterization of clinically isolates, four different biotype codes were obtained when the all isolated were tested simultaneously. Four different antibiotic susceptibility patterns were obtained. On the basis of these characteristics, the isolates were identified as Staphylococcus epidermidis.

  • Coagulase-negative staphylococci (CNS) have recently become the bacteria most frequently found in clinical infections. The aim of this study was to investigate the prevalence, antimicrobial susceptibilities, and molecular characteristics of CNS isolates from dental clinic environments in Busan, Korea. One hundred and fifty-four samples were collected from 10 dental clinics and dental hospitals in Busan from December 2014 to January 2015. Species were identified by matrix-assisted laser desorption/ionization–time-of-flight. Antimicrobial susceptibility was determined by disk diffusion methods. A polymerase chain reaction was performed to detect mecA, mupA gene, and SCCmec types. Of the 154 samples, 10(6.5%) isolates were identified as CNS (5 Staphylococcus epidermidis, 2 Staphylococcus capitis, 2 Staphylococcus, and 1 Staphylococcus haemolyticus). Among the 10 isolates, 6 were resistant to penicillin, 5 were resistant to gentamicin, 3 were resistant to tetracycline, and 2 were resistant to cefoxitin and erythromycin. However, clindamycin, ciprofloxacin, teicoplanin, and trimethoprim-sulfamethoxazole resistant isolates were not present. Genes encoding mecA were detected in 4 (2 S. warneri and 2 S. haemolyticus) isolates, and mupA in 1 (S. epidermidis) isolate. One methicillin-resistant CNS (S. warneri) isolate was determined as being of the SCCmec type I. It is concluded that CNS resistant to various antimicrobial agents was widely distributed in dental clinic environments in Korea.

  • We isolated seven tryptamine-producing bacteria from commercial salted and fermented sand lance (Ammodytes personatus) sauces using an L-tryptophan decarboxylating medium. These tryptamine-producing bacteria, identified using an API kit and 16S rRNA analysis, included Lysinibacillus xylanilyticus (one strain), Lysinibacillus fusiformis (four strains), and Staphylococcus epidermidis (two strains). Lysinibacillus spp. produced the highest levels of tryptamine in culture broth containing 0.5% L-tryptophan, compared with 1.0% and 2.0% preparations. After 72 h of incubation, Staphylococcus epidermidis produced the highest levels of tryptamine ($60.50{\mu}g/mL$ and $664.86{\mu}g/mL$) in culture broth containing 2.0% L-tryptophan. While Lysinibacillus spp. comprised the dominant tryptamine-producing bacteria in sand lance sauces, Staphylococcus epidermidis also showed high tryptamine-producing activity. This is the first report on the isolation and identification of tryptamine-producing bacteria in sand lance sauces.

  • To elucidate the question of whether biofilm formed by the intercellular adhesion (ica) gene cluster has influences on antibiotic resistance in Staphylococcus epidermidis, we compared 124 skin strains with strains isolated from 50 blood cultures that cause septicemic diseases. The results revealed that the blood culture isolates were more resistant to the antibiotics tested than the saprophytic isolates. Moreover, antibiotic multiresistance was more prevalent in the clinical isolates. In the blood culture isolates, $46\%$ of the strains were resistant to three or more antibiotics, whereas only $12\%$ of the saprophytic isolates were resistant to three or more antibiotics. Interestingly, these characteristics were highly correlated with the biofilm formed by the ica gene cluster. In biofilm-producing strains, $84\%$ of the blood culture isolates and $44\%$ of the saprophytic isolates were antibiotic multiresistant, whereas only $22\%=;and\;9\%$, respectively, were antibiotic multiresistant in biofilm-nonproducing strains. Additionally, in the biofilm-producing ica-positive strains, $89\%$ of the blood culture isolates and $57\%$ of the saprophytic isolates were antibiotic multiresistant. However, the rate of the antibiotic multiresistance in the ica-negative strains was very low, thus indicating that the biofim formed by the lea gene cluster in S. epidermidis is an important pathogenic factor in association with the antibiotic multiresistance.

  • The effect of $\beta$-glucan as an immunostimulant to increase resistance to bacterial diseases by enhancing non-specific defense mechanism in rockfish (Sebastes schlegeli) was examined by oral and bath administration. After oral or bath administration with $\beta$-glucan, the injection challenges with Vibro ordalii, Staphylococcus epidermidis and Edwardsiella tarda were performed to assess $\beta$-glucan efficacy. After injection of V. ordalii, oral administration for 30 days with 1% $\beta$-glucan showed 25% of survival rate. But all control fish died within 3 days after the injection. After injection of S, epidermidis, oral administration group for 20 and 30 days showed a remarkably increased survival rate of 95%. But oral administration of $\beta$-glucan to rockfish did not induce protection against experimental E. tarda infection. $\beta$-Glucan bath administration with or without formalin-killed V. ordalii showed that no protection was observed at 10 days after challenge. The results show that $\beta$-glucan to rockfish was effective to increase survival rate of bacterial infections of S. epidermidis and V. ordalii but not against E. tarda.
