The subject relates to an isolated antibody that specifically binds to O25b antigen of multi drug resistant (MDR) E. coli strains, its medical and diagnostic use, method of producing the antibody, including an isolated nucleotide sequence, plasmids and host cells as used in the production of the antibody; and further an isolated epitope recognized the specific antibody.

The present invention relates to recombinant Gram-negative bacterial strains and the use thereof for delivery of heterologous proteins into eukaryotic cells.

A molecular sensor that utilises dichroism can be used to identify the presence of specific molecules in a substance. The molecular sensor includes a sensor element comprising (i) a scaffold moiety and (ii) one or more receptor molecules for the target molecule attached to the scaffold moiety to form a scaffold/receptor complex, wherein the scaffold/receptor complex is modified to incorporate a chromophore and the modified scaffold/receptor complex has a high aspect ratio.

A method for manufacturing a structure for microbe detection comprises the steps of: reacting nitrilotriacetic acid (NTA) and an acid anhydride to prepare a first compound; chelation of metal ions to the first compound to prepare a second compound; binding the second compound and a microbe detector to prepare a third compound; and mixing an exfoliated transition metal-dichalcogenide (TMD) compound and the third compound to prepare a structure for microbe detection, in which the metal ions of the third compound are bound with the transition metal-dichalcogenide compound.

Methods and compositions useful in treating neurodegenerative disorders are based on septapeptides and extended forms thereof (or portions thereof) that exhibit chemokine activity with respect to microglial cell precursors.

A test device for indole concentrations in headspace gasses of bacterial cultures has a porous substrate imprinted with a wax barrier surrounding a test spot impregnated with p-dimethylaminocinnamaldehyde (DMACA). In embodiments, the test spot lies within a printed bar code and is configured to alter a reading of the bar code when the test spot darkens. The test device may optionally include a second test spot impregnated with Bromthymol Blue, Cobinamide, p-dimethylaminobenzaldehyde, or Chromotropic acid. The device is used by inoculating a sample into a culture; incubating the culture; inserting the test device into airspace of the culture, and observing the test spot for a color change indicative of indole presence.

A method for detecting verotoxin includes: providing a sample and a molecule that binds to verotoxin; performing an operation for purifying verotoxin in the sample by using binding of the molecule and the verotoxin; and subjecting the sample obtained by the operation to a first mass spectrometry.

A new class of pH sensitive fluorescent dyes and assays relating thereto are described. The dyes and assays are particularly suited for biological applications including phagocytosis and monitoring intracellular processes. The pH sensitive fluorescent dyes of the present invention include compounds of Formula I:

##STR00001## wherein the variables are described throughout the application.

The present invention relates to bacteriophage therapy. More particularly, the present invention relates to novel bacteriophages having a high specificity against Escherichia coli strains, their manufacture, components thereof, compositions comprising the same and the uses thereof in phage therapy.
