Μελέτη των ιστολογικών βλαβών του κερατοειδούς από και τα συστατικά της slime - GLP και LPS
… (a) by a single intracorneal injection of live bacteria of the P.a. prototype strain PAC-IR (20-30 cell/per injection), (b) by a single injection of 100μg slime-GLP and (c) by a single injection of 2μg LPS. Slime-GLP and LPS derived from the same strain (PAC-IR) of P.a. that used to induce …

The effects of administered indigenous micro-organisms on uptake of ¹²⁵I-gamma globulin in in vitro intestinal segments of neonatal calves
… uptake in segments receiving one ml of either live intestine origin bacteria culture, sterile microbiological broth or autoclaved bacteria culture with four h incubation followed by 1.5 h exposure to ¹²⁵I-gamma globulin. Two treatments measured anaerobic microbial growth after four h incubation …

Ionic Control of Porin Permeability
… within the outer membrane of gram-negative bacteria that allow nutrients, and small molecules, including antibiotics, to enter the cell. Electrophysiological studies on porins reconstituted in lipid bilayers have suggested a dynamic regulation of porin conductance through changes in the …

Innate memory to bacterial infection
… markers analysis, cell depletion, heat killed bacterial immunisation and bacterial infection.<br/><br/>This study hypothesised that following immunisation mice would be able to restrain bacterial growth and aimed to investigate the magnitude and longevity and specificity of the response. …

A SYNTHETIC TMRNA PLATFORM FOR ELUCIDATION OF BACTERIAL PROTEOME REMODELING UNDER STRESS
… reprogramming is a key component of the bacterial stress response and is a function of mRNA stability, protein turnover and proteolysis. Total proteome measurements give a view of the stable proteome but can fail to capture dynamic changes under stress, including incomplete polypeptides …

The effect of antibiotic treatment on Haemophilus parasuis colonization, disease and immunity
… colonization by temporarily reducing the bacterial load in the upper respiratory tract. However, enrofloxacin was unable to eradicate the organism. Then, it was demonstrated that the inoculation of pigs with a low dose of pathogenic H. parasuis protected pigs against secondary infection. …

Presence and Role of Acanthamoeba in Wound Infections
… well known that Acanthamoeba feed on and protect bacteria. The role of Acanthamoeba in wound infections is not very well understood. It is possible that the presence of Acanthamoeba in wounds is one of the key factors for such re-infections. In this study, 140 wound swabs were collected to check …

Immunomodulatory effects exerted by Lactobacillus salivarius strains on innate immune cells
Despite increased application of commensal bacteria for attempting to improve the symptoms of a variety of inflammatory conditions, including inflammatory bowel diseases, diarrhoea and irritable bowel syndrome, therapeutic approaches that involve live bacteria are hampered by a limited …

Modeling the interface between biological and synthetic components in hybrid nanosystems
… in (1) immunosurfaces used for detection of live bacteria; (2) protein transport through a nanochannel; (3) deriving the Langmuir constant for adsorption for small, organic molecules on synthetic surfaces; (4) creating a multiscale model for transport in micro- and nanofluidic devices; (5) …

Development of novel metal nanoparticle based methods for detection of bacteria using surface-enhanced Raman spectroscopy
… Spectroscopy (SERS) for the rapid detection of live bacteria by analysis of the headspace above bacterial cultures. It is knownt hat in-situ SERS can be used to detect vapour phase dimethyl disulphide (DMDS), which is a metabolic product of live bacteria. The test experiments in this thesis were …

Assessing Helicobacter pylori's HcpE and DsbK's Effects on Immunostimulation in Host Gastric Cells
… gastric) cells were exposed to either live bacteria, bacterial culture supernatants, outer membrane vesicles (OMVs), supernatants devoid of OMVs of wild-type and knock-out mutants of DsbK and HcpE in two HP background strains or purified recombinant HcpE (rHcpE), followed by IL-8 …

Role of Mincle in Immune Responses to Orientia tsutsugamushi infection
… murine bone marrow-derived macrophages (MF) to live or inactivated O. tsutsugamushi. We found that while heat-killed bacteria stimulated transitory Mincle expression, live bacteria generated a sustained Mincle response. Notably, infection had limited impact on other tested CLRs or TLRs. …

Engineering protein self-assembly for biosensing applications
… to generate FRET signals for nitrite sensing in live bacteria. We extended this system into a cost-effective nitrite sensing platform by creating coating materials. Molecular docking simulations were performed to understand the binding interactions between NasS and nitrite, guiding the …

In vitro evaluation of equine bone-marrow derived mesenchymal stromal cells to combat orthopedic biofilm infections
… is often due to biofilms that are communities of bacteria that are adhered to a surface or to each other and are surrounded in a self-secreted extracellular matrix. The biofilm matrix protects the indwelling bacteria from being killed by antibiotics and the immune system. Biofilms also stimulate …

Melioidis: an investigation of cellular immune responses
… infections with other facultative intracellular bacteria such as Listeria monocytogenes and Legionella pneumophila, has been shown to be mediated largely by a cell-mediated immune (CMI) response of the host. B. pseudomallei is also a facultative intracellular bacterium but despite decades of …

Impact of cryoprotectants during freeze drying on Lactobacillus plantarum viability and their role in enhancing probiotic storage stability
… as studies have revealed the potential use of live bacteria known as probiotics as potential therapeutics for restoring and maintaining human health. These probiotic-biopharma formulations must contain the right strain(s) in sufficient numbers when administered to confer the desired health …

Intracellular triggering of inflammation by the extracellular bacterium Pseudomonas aeruginosa
… system is found exclusively in Gram-negative bacteria and it forms a conduit between the bacteria and the host cell through which effector molecules can be translocated. These effectors alter the function of the host cell to promote survival of the bacterium. Infections are detected initially …
