Cell Staphylococcus epidermidis

In some cases, catechins can also act in synergistic mode when used in association with currently used antibiotic molecules (Table 2). EGCG exhibited synergy with /3-lactams. Sudano Roccaro et al. [73] found that this compound is able to reverse tetracycline resistance in Staphylococcus epidermidis and S. aureus isolates. This synergistic interaction has been explained by inhibition of tetracycline efflux pump activity in microbial cells resulting in an... 

U V-resonance Raman spectroscopy is not only used for bacterial identification but also to study the influence of antibiotics on bacterial cells. The mode of action of amikacin on Pseudomonas aeruginosa cells was studied by Lopez-Diez et al. [83], Neugebauer et al. monitored the effect of ciprofloxacin and moxifloxacin on the chemical composition of B. purnilus and Staphylococcus epidermidis [62, 84],... 

P NMR has been used to investigate the effects of three anti-microbial peptides isolated from Australian tree frogs Litoria caerulea and L. genimacu-lata on the cell membranes of Bacillus cereus and Staphylococcus epidermidis. The wide-spectrum antibiotic peptides caerin 1.1 and maculatin 1.1 disrupted cell membranes causing an increase in the isotropic P NMR signal. However, caerin 4.1, a narrow-spectrum antibiotic, did not affect the P spectra of these bacteria. ... 

Other non-immimosensor-based Pz sensors for the detection of bacteria have been produced. He et al. described a separated electrode Pz sensor for E. coli [106]. Ebersole et al. used Pz detection to monitor the growth and metabolic rates of E. coli cells [107]. Bao et al. developed a sensor for the detection of Staphylococcus epidermidis [108]. A Pz-based assay for Sac-charomyces cerevisiae. Bacillus subtilis and Klebsiella spp. have also been described [109].

S. aureus contains three different forms of tRNA specific for glycine, of which two can act in protein synthesis, though all three will serve in the assembly of peptidoglycan. The synthesis of wall material is presumably the sole function of this last, which cannot bind to any of the known glycine codons. A similar situation exists in Staphylococcus epidermidis, where three of the four t-RNA forms specific for glycine will facilitate its incorporation into protein, while the fourth will not, but is an effective donor in the synthesis of cell wall peptidoglycan. In other species such specialised forms of tRNA have not always been found and the generality of their occurrence is uncertain.

The surface stiffness-dependent behaviour of bacteria has been less explored compared with that of mammalian cells. Using polyelectrolyte multilayer thin films composed of poly(allylamine hydrochloride) and poly(acrylic acid) as model materials, Lichter et al. found that the adhesion of Staphylococcus epidermidis is positively correlated with the stiffness of this material with a varied Young s modulus from 0.8 to 80 MPa, independent of surface roughness and charge density. Other photo-cross-linkable polyelectrolyte films made from poly(L-lysine) (PLL) and hya-luronan derivative modified with photo-reactive vinylbenzyl groups (HAVE) have also been examined. The adhesion and growth of two model bacteria, E. coli and Lactococcus lactis, were examined on the softer (non-cross-linked) and stiffer... 

Vancomycin-modified Fe-Pt MNPs have been reported for selective emichment of vancomycin-resistant enterococci and other Gram-positive bacteria (Staphylococcus aureus and Staphylococcus epidermidis). The selective interaction between MNPs and bacterial cell walls (expressing o-Ala-o-Ala as the terminal peptides) is through multiple hydrogen bonding (Gu et al. 2003).

The first examined bacterium with TERS was bacterium Staphylococcus epidermidis [110—112]. More statistical measurements on S. epidermidis were performed by collecting 15 spectra at one point per cell and five cells in total [112]. From these spectra, a single average spectrum for each cell was generated and characteristic bands for teichoic acid (a (l-3)-linked poly(glycerol... 

Figure 5.28 PCA scores plot of E. coli 0157 H7 (EC), Salmonella Pfphmunum (ST), Staphylococcus aureus (SA) and Staphylococcus epidermidis (SE) pure cell samples. The PCA model was constructed using the spectral range from 400-1800 cm" [276].
